Slashing Tips

You know that part in a movie where some guy gets sliced up with a sword and you can see a big cut across his ninja shirt?… Well usually they do some fancy editing where he has a robe without a slash and then it cuts to a close up where the shirt now has a big rip… This actually works really well, especially with a nice sound effect. But I wanted to do the slicing all in one continuous take using computer technology!

How would you do it?

Looking forward to seeing how you did this--especially how you turned Tito's chest into metal to deliver that slicing sound. ;)

That's cool. I think I might have to do something like this for an upcoming episode of my web series My Ghost Sister & Me, but that will involve a stabbing so it's a bit different

Easy:

1) Take knife
2) go to friend's house
3) approach victim
4) slash victims shirt

trick complete.

haha you could have been a comedy writer if you didn't get into after effects.
November 23rd, 2010 @ 8:33 pm
There are two layers that I noticed. One was the whole shirt and the other, the footage. It was shot when the shirt was already torn. Then he takes the untorn layer and puts it on top of the footage and blends it together.
You can see how the untorn footage doesn't react when he moves around (the wrinkles/waves) while the live footage layer shirt is reacting to the movement.

Did I get that right?
Took me a few replays to see it. Good job!
    Brent
    December 7th, 2010 @ 5:07 pm
    Yeah I figure this is the way too... you could have the actor getting slashed act out the scene twice, once with the shirt fine and once with it slashed. That way you would have a bit of movement on the shirt when you mask it..?
    Iggy
    July 5th, 2012 @ 1:59 pm
    Phil - i think youre right. I noticed a disparity between the relationship of the logo to the shirt's neckline before and after the slash.
therealpanse
November 23rd, 2010 @ 8:34 pm
in this case i would prepare te slashed shirt, talk him into wearing it (and keep a perfecly good one for myself) and hide the cut in it with some graphic which is tracked to it.
easy as pie
November 23rd, 2010 @ 8:35 pm
first i'd wait for the tutorial....
which might include tracking the footage.
taking a photo of a slashed shirt worn by tino
dropping that photo on top of the footage and link it to the null..
then use that one transition (wipe?) to reveal the cut with the knife slash.
November 23rd, 2010 @ 8:38 pm
I'm gonna say the guy already has a torn shirt and you used Mocha to put a layer of the guy's uncut shirt on top of that, which you have in the beginning and mask out when you do the slash. Either way, very effective!

Did you film yourself in front of a green screen and then overlay the footage on T to the No? The keying or roto work on you looks a little off. It could use a little better color correction. The shirt could have been done a couple of ways.
November 23rd, 2010 @ 9:02 pm
@arvin, yeah there ya go. reverse of what i said. the torn shirt would be in the footage and then track the unslashed shirt over top.

I like how you are forcing people to think about your process before you reveal. It is a good learning tool.
Josh
November 23rd, 2010 @ 9:28 pm
Good job, but you need to work on making the angle that you cut with your knife the same as the angle of the cut on the shirt; during the footage you cut the shirt at a more horizontal angle than the rip in the shirt was at. This did not look very convincing to me.
November 23rd, 2010 @ 9:43 pm
sweet! nice job as usual Andrew
Kerem Ogan
November 23rd, 2010 @ 9:46 pm
hi andrew its nice:) like others:) my english is not good (i didnt read other comments:)

i guess you maked reverse compositing...

actually t-shirt is torn from starting... but you tracked and put the fixed tshirt from start...and when you slice the tshirt...you switch real torn tshirt...(some paths for transition)...and some rotos of course for your arm :)

i guess this is your way...

my english is not good sorry i hope u will understand me:)

take care...
Ryan
November 23rd, 2010 @ 9:52 pm
Funny looking finger :D

I'm pretty sure that's a thumb haha

but pretty cool effect.

Not sure how its done but going fram by frame at 0:44 i can see there are multi layers. On the left side of the knife you can see a slight image of a building that its further along on the t shirt, although i could be wrong.

I think you've basicly tracked over the rip and covered it with a real image of the t shirt and then keyed it out with the knife! nice job tho!
Simon
November 23rd, 2010 @ 10:29 pm
It looks fake because of the direction of the knife you swung was different to the cut on the t-shirt
November 23rd, 2010 @ 10:36 pm
Thanks for this work (blog)! :)
November 23rd, 2010 @ 10:42 pm
Hmmm...maybe you tracked an image (logo) of the shirt over the torn one....and revealed it after the slice? Seems logical but I know you would have a more slick approach. I guess I will wait and see.
November 23rd, 2010 @ 10:55 pm
Amaziing excellent work andrew
thanks for your videos
November 23rd, 2010 @ 11:08 pm
Woot! Thanks Andrew! :)
November 23rd, 2010 @ 11:39 pm
Sound effects are a bit much, but thats not what you're demonstrating! Great work. As always, I cant wait for the tutorial (if any)!
Brandon
November 24th, 2010 @ 12:44 am
I would say he was wearing the cut up shirt the whole time during that one shot, and you filmed him with the unripped shirt before or after, then made a matte of the uncut area and tracked that onto the ripped shirt. A traveling matte would need to be used alongside the arm to cleanly reveal the ripped shirt. But if I had to do this myself, I might try avoiding the extra compositing work and just film him with a ripped shirt the whole time, BUT I would neatly tape up the shirt from inside and attach some fishing wire or something undetectable to the tape. I would have the guy cutting block the victim a bit and when he goes to cut I would have someone pull on the wire or trigger device and the shirt would come apart. It might take a couple takes to get it right though.

November 24th, 2010 @ 12:50 am

November 24th, 2010 @ 12:54 am
cool !!!!!!!!!!!!!!!
November 24th, 2010 @ 12:58 am
I rekon you have rotoscoped your body out and carefully got tito to get back in the position he was in as you cut. that way all you would have to do is just put the two tito footages together and do a quick keyframed paint job on after. Just what i would do.
Are you actually going to tell us or just leave us hanging?

Hey Andrew and Team, really nice work.
May you show us, but how did you do it?
Do you made a Tutorial about this?

Greetings from Germany.
November 24th, 2010 @ 1:37 am
No CG there.

There was strange rounded fold on the end of the cut.
I suspect it's something that made that precutted cut to spread.

November 24th, 2010 @ 1:43 am
that was so funny.
i thought i would talk to you about knife safety... but then i changed my mind. lol so funny
November 24th, 2010 @ 1:49 am
Andrew, you find the best way to animate it. My team would do it for real, wearing a green bullet proof vest under the shirt. So the guy would look more scary and a lot more concentrated.
Also we would catch the scene with 3 cams out of different angles. So you get what you need. If you try it, tell the guy that he has to protect his right arm... there would be a cut too!!! Greenscreen do the rest... Greetings Joe from Germany
Malcolm K
November 24th, 2010 @ 1:56 am
I would do it using Andrew Kramer, and some kind of acting machine...maybe some sort of Sam Loya, or something. Can somebody perhaps invent that kind of guy, or can VC start loaning him out for holidays and birthday parties?
November 24th, 2010 @ 2:14 am
I would use after effects

A sport shirt is already torn, remains to impose the photo
of logotype or (front of shirt)
next mocha fix this guy, and then to impose the photo of shirt.There is to do some work with subtletie .


It is my opinion ))))

Don't do it at home!

Go to a friends house!!!

:D
November 24th, 2010 @ 3:28 am
I recon the shirt was already ripped and stand pretty still to make it easier to mask over in AE with a tracked mask or something. Would only be a really small mask as you only want to hide the skin and fix the logo up. Because it's only a few frames you could frame by frame fix it.

That's my thoughts :)
November 24th, 2010 @ 3:30 am
Good job
Andrew, why you dont go to your friend house ?

November 24th, 2010 @ 3:51 am
Hi Andrew!, Cool effect!

My guess is that you've made it with greenscreens. The clue is that your friend is trying to look at you while is waiting the cut, but he misses. So there must be two layers at least, you and him. You have been recorded with a greenscreen (btw good job with the motion blur of your hand) and putted on top of the sliced actor and the backgroud (the stage).

Then, the trick of the sliced shirt can be done with a simple film cut, making first the shot with the untouched shirt, then the one with the cutted shirt, and finally putting one after the other. Just have to be carefull with the position of the actor in the two shots, and maybe retouching it a bit to sell it better.
This second part could have been done in a diferent layer than the backgroud with a greenscreen too, this way it would be easier to match the two shots. And the fact that the feets are out of screen helps a little.

At the final shot your are both actually in the place where you fake at the slicing, and that really helps a lot selling the hole secuence.

So that's my guess, no matchmoving, just the greenscreens old way.

the knife direction is not perfect for the cute direction

try again ,,,, lol
ShoeToad
November 24th, 2010 @ 4:17 am
How I think it's been done:

1. The camera is mounted on a tripod.
2. A specific place for Tino's feet is marked on the floor by two markers (with tape or something), which is off frame (we don't see Tino's feet when the cut happens).
3. Andrew starts acting, goes to Tino and pretends he cuts him.

During the whole take Tino wears his unshredded shirt and stays put.

This is the end of take 1

Take 2:

1. Tino's shirt gets prepared, i.e. Andrew cuts the shirt with the knife (off set).
2. Tino puts on the shirt, goes to the marked spot, tries to match the previous stationary position as close as possible and then pretends he gets cut.

We now have a shot of Tino alone pretending he gets cut.

We now bring those two clips together:

At the moment that the cut should happen in take 1, take 2 is rotoscoped in, i.e. Tino acting like he just got sliced. Add SFX and you're done.

November 24th, 2010 @ 4:29 am
HOW ITS MADE:P

The longest footage in the video is with his shirt cut open.
So I think he allready had a cut shirt and andrew tracked the shirt so
the logo on the shirt was placed on the same position in Afx.
Little roto work and coloring. done.

Fallon
November 24th, 2010 @ 7:44 am
By some freakish coincidence, I had to do this EXACT same trick on a recent project (albeit with prosthetic wounds and CGI blood spray instead of the much more elegant ripped-fabric seen here). I used (I think) pretty much the same method: make sure the victim remains stationary, make sure the camera is locked-off, cut the shirt between takes, and then you cut the shots together RIGHT at the point where he makes the sudden jerking movement so that any minor discrepancies in his position disappear.

Then you clone and roto the two takes together, it's nice and quick so this is not a huge task. You might also, depending on the shot, want to bring the slash in gradually with a linear wipe.

Also, depending on the shot (we had to do it several times from different angles - basically the guy slashes up a bunch of people in a public toilet: classy) you might want to track a masked-off version of the slashed shirt onto the un-slashed one, just to ease the transition between takes. We had to do this because it took a little while to apply the prosthetic wounds to the guy's torso and his position changed a little too drastically.

One other difference was that we were using high shutter speeds (for that pseudo documentary, shaky-cam, jump-cut look that everybody goes for these days) so we didn't have to contend with motion blur.

Gruselgurke
November 24th, 2010 @ 7:49 am
Maybe take 3 seperate shots. Andrew in front of a green screen, and two shots of Thino (or what his name was :D), maybe also in front of a green screen but I think there is no real need for that.
So 1 Shot where Thino has a non sliced shirt and stands there, then he don´t change his position, gets the sliced T-Shirt. The Camera men gives him advice how he stands in the last shot (doesn´t need to be 100% perfect), then he just makes his shocked movement backwards and in post you take the frame that fits it bests. Put Andrew into the scene and youre done :D
November 24th, 2010 @ 7:50 am
I would have used a t-shirt with a huge cut. then I would have tracked the same texture as the shirt with out cut to the shirt and remove the texture while the slice is happening. I think that's what you did Andrew. am i right? :3
Avinash
November 24th, 2010 @ 8:09 am
i agree with gruselgurke and seeing in ur shot andrew ur hand is originally over the cut u can use a mask reveal as us hand comes down with the knife ... the cut is revealed so it looked more real plus if tito doesnt move around in the first shot and u can line up the ripped shirt with the original ... then it should work pretty fluently ... i'll go try it. who wants to volunteer to get sliced? anyone? anyone? there will be cake!
Avinash
November 24th, 2010 @ 8:12 am
or maybe even body splicing, like the guy that did the supernova music video, u can use tito's head and body but for the chest part u use a manniquinn with the shirt, u then carefully mask it out and splice it together with tito's head and arms and any other part i may have left out ... lol ... still waiting ... any volunteers? i got a chainsaw i wanna use :D

andrew with green screen, and tino's shirt is cutted, with motion tracking is replaced with an uncutted for the first frames, and a little transition for the cut. I think.
sorry for my poor english
November 24th, 2010 @ 9:19 am
I'd say, project an uncut shirt (layer B) on top of a cut shirt (Layer A)by tracking the movement then the slice of the knife which is just the handle with a cgi blade reveals Layer A. Light conditions and movement should be controlled to prevent color difference and scale.

Addisohn
November 24th, 2010 @ 9:33 am
Hmmm. Maybe you were in front of the green screen when you made the cut, then you filmed the other guy as the background shot. One shot with the cut in his shirt, then you cut his shirt while he stayed still. Then you matched the clips together. That's what I would've done.
November 24th, 2010 @ 9:50 am
easy!!!
u just put a clip with him with already a cut in his shirt!!!
November 24th, 2010 @ 9:58 am
From my first assumption watching it really fast I'm guessing the shirt was already ripped to begin with and you just tracked on solids or the shirt logo in the beginning...it looks really cool and real! Except for the cheesy sound effects haha
Jack Howard
November 24th, 2010 @ 10:02 am

November 24th, 2010 @ 10:15 am
It's really simple, actually.

1: Trick Video Copilot into sending me a free T-Shirt
2: Tell Tino he's going to be elected a president so that he'd come here to my place.
3: Find a local soldier and beat him up. If everything is OK, I'm gonna have a knife.
4: Take a camera, knife and Tino (he'd probably go with me for some cookies, though). Slash Tino in the chest!
5: Take Tino to the hospital for treatment.
6: Trick VCP into sending me another free T-shirt.
7: Wait for a while for Tino to heal.
8: Shoot a footage of Tino Hertz with a brand new Copilot Tee (and promise not to slash him again. Give him two cookies as an apology).
9: Use some fancy video editing to blend the two clips.
10: Show the awesome effect to Andrew Kramer and ask him if he could do it better :D

I recognize that the top of the mountain on his shirt is changing in a pretty odd way for jsut one frame but I have no clue what that have to do with the effect :S

In the next frame where you "cut" the lower part of the shirt the mountain is back to normal.

Very cool! I can sense a tutorial coming ;)
November 24th, 2010 @ 11:03 am
Here's my take,

Andrew has been green screened in, because I think I see a little bit of green spill on the back of his t-shirt. Also, as he is no Sam Loya :P, his slashing motion isn't accurate with the slash itself.

The T-shirt ripping open, well Tino's wearing a ripped shirt through out the whole sequence and Andrew's stitched it together using some combination of masking and the puppet tool.
CANT WAIT FOR TUTORIAL!

Nice. If it was Sam, he'd be on the floor gushing blood, but since it's Tino, he gets away with only a ripped shirt.

November 24th, 2010 @ 2:50 pm
Ok I noticed that at 0:42 the blade disappears. just for one or two frames but it disappears. So my conclusion is that you use 2 takes and a bit of roto magic.

1. You as you pretend to slice him.
2. Tino who stands still with an untouched shirt and in this take someone cuts his shirt and with a bit magic in after effects you dropped these frames and so it appears that his shirt gets a cut from the knife.

Then you used some roto skills and composed these shots together
November 24th, 2010 @ 2:54 pm
hi.
i think that you stood far enough away not to hurt him (or you were greenscreened in) and someone tore open the shirt with a thread. For synchronizing the two things together it would be best if you were put in later. like some extra swat that have not been there.
But i am looking forward to your tutorial.
they are always so much fun. and interesting.
keep them coming.

Great clip!

I think it's Tino's magnificent acting that actually sells the clip. My guess would be the shirt is already ripped so when Tino takes the hit he has to lean forward to get the shirt to open up. I bet this took many many takes to get right!

But it was sold well by Andrew talking first and then having a match edit when he turns from the camera with the knife to slash Tino. It's more shocking!

After Effects was used to draw in the first line of the cut. And maybe to patch up any gaps in the shirt before the knife "slashes" it open.

My guess! Might be wrong but there's more than one way to skin a cat as other suggestions have shown.

November 24th, 2010 @ 3:23 pm
Track!

I would track in a clean plate (using Mocha, or what have you) of the shirt(un-cut) onto his already cut shirt (live action shot), then when the knife does a slash I would mesh warp and cut or morph to the live shirt.

That's what I would do...
Not sure if someone has put this yet.

Nice though Andrew

I skipped whole comments so sorry for repeating. About the video: you could do better. :) The sound is too soon and important thing is also the angle of your cut. You swing the knife horizontally but the cut is pretty much vertical. There would be also some things about acting (I don't believe you that swing), but it's pointless since this is about the effect. Hilarious intro, though. :)

November 24th, 2010 @ 7:15 pm
so easy... the entire shot when you slice the knife was was with the tshirt already cut it...
then tracing the footage you added some mask to another shot with a good tshirt on top then some rotoscoping in your arm and all set to cut anything... it would work for anything though.. like cutting his troat making a big and gore cut with some nose wax and fake blood then filming a clean shot without make up... add some blood from Action essentials 2 to more realistist reaction and all ready...
actually a have kill to many ppls with this kind of effects just for fun :D

November 25th, 2010 @ 2:28 am
Hi,

I think I would start with a shirt which is already torn and then repair the tear with a layer of artwork which is motion tracked into the right place on top of the figure.

When the knife stroke comes down I would use masks (or there's actually a filter called cut or tear or something) to open up a slice.

Initially you would need a dummy skin layer before you transition to the real footage of the torn shirt.

Your slash stroke doesn't quite match up with the cut made in the fabric.

Maybe the initial fake cut could mimic the slash you make in the footage and then switch to the real torn shirt but watching the replay I think you've made a real effort to match the slash you created with the real cut.

I was replaying this to see if the location of the cut changed in relation to the artwork on the tee but it's really close.

Cool little video. It would be cool to see an 'Enter the Dragon' style blood stripe on the skin under the shirt as well!

November 25th, 2010 @ 2:43 am
Hey guys :)

I learned AE just by watchin Andrew´s awesome tutorials! Cause of that ill think there are more layers and Toni fought on a green screen vs. an invisible knife. Once he stood in a good shirt and on the other hand he did his move with an cuttet one (*snief* how dare you are to destroy such a shirt?!). These vids are overlayed and in the angle of the cut you put the Layer with the cuttet shirt on top (as already from other guys explained ;) ) <- think a little bit about the "advanced car hit"-Tutorial :D

Sry iam not realy aware of english ^_^

Nice day everyone :D
November 25th, 2010 @ 3:02 am
1.- ANDREW IS COMOPOSITED IN THE SHOT: he was in green screen and then composited with Tino. This one is pretty obvious.

For the cutting part I suppose is one of this:
A.- Tino has the shirt already cutted but atached with tape (or something) and nylon wire (fishing wire) then he pulled the wires with his hands so the shirt could be released from the tape. The cutted shirt is clonned and tracked, you can see the pixels blured near the cutted area.
B.- The same from point A but in this part the tape (or pasted parts with glue) is placed in a way that When Tino Streches his torso he releases the shirt (Look how he stretched his body towards Andrew instead of the oposite direction, wich is the logical reaction) The same, clonned and tracked cutted area (I suposse with his marvelous new plug in :D )
C.- Or he has no tape or anything and the Shirt gets in the place by itself.

The clonned part can be seen better the frame before the slash appears (In the bootom part of the shirt, a rolled thing appears and if you pass from the previous frame of the slash to the frame with the slash you'll see in that lower area the clonning)Also that rolled thingy should be moving (because of the laws of physics and stuff you know XD) instead of just been there without moving

It's a really really great effect as always and I hope I have cracked it well XD Andrew should give a T-shirt to the winner! hahaha Greatings from México Andrew! You Rock!
November 25th, 2010 @ 5:08 am
Well... what I see is that the scene is devided in 4 blocks... only the 3rd has the cutting knife effect...

The effect was made with a pre-cut t-shirt. Andrew passes the knife close to Tino without touching him
In post-production you cleaned the t-shirt before the cut... to make it complete(whit now cuts) you tracked the clean t-shirt to the cutted one and then composite with a wipe mask and some color matching...

The sound effect is from library lol of course and i think the sound is not sync... but sounds cool this way :)

Cheers from Portugal...

November 25th, 2010 @ 5:12 am
I think when he slices with a prop knife, its attached to a string which then pulls out the cut from the precut shirt. i doubt its with cg the only cg may be the knife but i think he had the shirt precut tied it closed then the prop kinfe un ties the hidden cut. =)
Syny-Proxy
November 25th, 2010 @ 5:24 am
Hey, Great !
Actually when the sound came a little bit earlier than the cut it seemed like those Ninja movie when the Ninja is sooo fast and cuts the apple but you see it split until one second =)
Or,Like does scenes in Power Rangers when they cut the other Robot with the sword, and that the robot get cut until they turn around to be front with the camera and then the Robot explode !

Not quite sure about the shirt. The angle of the knife and the slice is a bit of, but looks very convincing. I'm guessing the green screen is involved. The backgrounds are stills, that's why you cut in the pan. Good idea having the green screen in the second background. Throw people off.
November 25th, 2010 @ 10:32 am
The shirt was already cut...the logo on the shirt was masked out and wiped. If you go slow frame by frame, you can see how it was tracked and masked. It still an awesome look!

DOM
November 25th, 2010 @ 11:22 am
Well, from the top of my after effects knowledge, I would try to achieve this effect by pre-cutting a tshirt, closing the recently created cut with some sort of tape, add a very thin (transparent) line to be pulled in a synchronized movement while swinging the knife. It`s funny how Andrew`s left hand moves. Sure there is some after effects in there. I notice a swirl of left overs on the end of the cut that suddenly disappears. Anyway, great scene.
Washington
November 25th, 2010 @ 11:49 am
I would use a tripod, make 2 takes one with the shirt uncut, first take its just the acting the actors are at a safe distance from each other, but distance is hidden with the angle of the camera. then make sure actor leans forward to the hide the imaginary cut.

the cut will show when they are straightening up in the second take. the first slash I would paint it on so that it animates as the slash is going down. and hidden again as the actor leans forward.. Join the two together wallah! English is not my first langauge hope it makes sense.
Dorian
November 25th, 2010 @ 11:51 am
Ok, I think you pull a string from the floor right in the moment that you give him the knife movment, so that string release an adhesive tape inside the shirt, am I right?

1.You took a picture/video of the shirt non-ripped.
2.You motion tracked his chest.
3.You cut out the logo from the non-ripped shirt in post and parented the logo to the null with the tracking data from his chest!
4.Then you did some masking and such and bam!
November 25th, 2010 @ 1:09 pm
That's just a fast cut with a little bit of masking, Andrew. Requires acting and Movie Maker :P

How would I do it?

Well, Green Screen Footage of sir Andrew (if your lazy) or just masking out, over a Tino footage with a riped shirt. I'll shoot a third footage of Tino with a normal shirt and after that I'll track the Riped shirt footage and place a masked out version of the normal shirt and put it over the riped shirt, after that is just a simple linear wipe in tone with the knife movement :)

Tomas
November 26th, 2010 @ 12:08 am
Actually, is very easy.

The T-shirt was already slashed. So, in After-Effect you only has to clean the t-shirt where it was slashed, paste the logo over the t-shirt and track it. So you have a new t-shirt, and then unmask it in the moment you make the cut. And this is it!

November 27th, 2010 @ 2:10 am
wow nice way to hide the transition, when your arm goes up it covers the area that was cut, but the trick was how did you cut the shirt without actually cutting it.

i will have to say that you could have used mocha to track it and put the shirt uncut on him or at least partially (to cover up the cut area), but theres a little color offset where the cut was made, telling me that you did cut the shirt before hand.

now is it possible that there is a secret cut in this and you used a program such as istopmotion to get you position exact, absolutely.

there are multiple ways of doing it. but sir how you did it, you did an outstanding job.

Hey, I'm making a zombie movie and need some slashes with various things. Only I need the slash to hit more than the shirt. I need it to be able to slice or chop somebody into peices (of course, the victims are zombies, so it's for a noble cause). How would you hack something apart using after effects and make it look impressively real? Thats what I want to know.

November 28th, 2010 @ 5:47 am
Yup, I'm definately going for wearing a precut T throughout the shot, and tracking in an uncut shirt over the top (maybe from footage shot beforehand, maybe just a photoshop file of the logo on a blue background) and then simply 'revealing' the cut comp underneath when it's time using a mask.

I fink that'd work anyway.

I have no idea how you pulled this off :S. I could think of 2 ways:

1. tino is wearing ripped up shirt, you tracked, roto-ed etc...

2. He was wearing some wort of (skin colored) protection on his chest.

Come on you Guys! Dont you know how this is done?

Andrew is A Super Ninja.. There was no special effects at all.. It was all precision work. He probably traint with kungfu panda for many and many years to perfect it..
No worries for the guy been slashed because it's not the real Tino it is a Robotninja replica of Tino.. Specialy designed for this exercise.
The Full preformance will be done by Sam. Yep changes will be made here.. The knive will be longer. Sam will be standing closer. Andrew will be drunk and blindfolded (no need for that, but hé) And there will be a britney spears song playing throughout the act.. (so I have heard, not sure.. almost positive but never know for sure..)

Thank you Andrew.. Now show us the TRUTH.. I know it is OUT THERE!

that was funny the knife sound gave it a great touch lol any chance going to show some cool stuff from the Ninja Assassin movie. this movie has some great effects that you guys have in your tutorials and some other stuff that would be great to learn. the trailer alone had some great effects lol

The shirt is already cut.
The uncut patch was motion tracked on and the slash was the wipe that removes the patch and reveals the cut.

LOL! Always better to do at a friend's house!

Awesome Sound FX! Really sells it!
Are the lights in your studio that cool, or was that a color treatment?

I'm guessing the sandwich was pre-cooked and the little Asian kid was CG. There were way too large birds to safely place a real child in that scene. Other than that, all Kramer had to do was was add a lens flare.

That's really cool... I think it was done by...1 he started by first wearing the shirt untorn and taking a reference shot of the untorn shirt then compositing that over time by painting on frames and tracking the subjuct, (not necessarily in that order) using a null to link the position of the tear to trackers on the shirt. I think??

November 29th, 2010 @ 1:03 pm
Hahahahahaha! That was epic! It's always good to have knowledge on how to properly cut a victim with out a bloody cleanup afterwards! :P

I would love to see a tutorial as well if possible, thanks for the inspiration and awesome VFX wisdom Andrew!

gotta agree with khamski there is a weird fold on the shirt, seems like that has something to do with it. cant wait to see how you did it!

I noticed a small piece of tap on the left hand's thumb. I am guessing you had some fishing line tapped to it and as you did the slicing motion, you pulled a small layer of tap off his shirt which kept it together.

Am I close....or way off?

November 30th, 2010 @ 10:26 am
Hrmm.. did you cut the shirt before and then just paint over it in after effects? I noticed that the slice in the shirt does not follow the movement of the knife exactly. Thats the only thing i can think of right now. Very nice job btw
November 30th, 2010 @ 3:09 pm
Good work! I think that the video is perfect!

I think that the victim has a Quatto on his tummy. For this scene, little Quatto slices open the shirt from the INSIDE with his mini stomach mutant size knife.

tracked torn shirt...
diagonal (cutting path) piece of t-shirt art placed on top to cover the cut...

you can see it's been masked out by the split&sliding "D" in "VIDEO"

right?

Hi Andrew, I follow you from Italy. You're awsome.

I'think he (TINO) was alrady wearing the cutted shirt. I noticed the the videocopilot logo non the shirt is not reacting very much befor you cut... mocha would track perfectly that movement...
It's probably wrong but I think that's the way I would workaround a shot like that...

:-)

There is a cut between frames 1055 and 1056.

December 5th, 2010 @ 8:38 pm
This is pretty obvious.

The poor quality of the videocopilot shirt means it's prone to just suddenly developing tears and holes, you simply film enough takes and eventually the shirt falls apart on it's own.

Hi Andrew,

As usual, another great effect!

I agree that you also tracked the videocopilot logo and t-shirt on to Tino and then after your arm swings the knife you reveal the already cut s-hirt.

However, this would be really difficult to track and blend together nicely due to the detail of the logo and having to match this to Tito's movement and with the fact that the shirt is cut open and dangling.

The only way, would be to restrict the dangling of the cut-shirt by pinning it or taping it together so that it does not sag. That's why I think Tito jumps back and moves his arms so that he unpins it.

Can't wait to see how you did it!

Ciao from Montreal

Great Job,hey i was thinking a while back you talk about the canon 7d in the blog. It would be nice to have a blog about which hd Video camcorder for us beginners are good to use.... Just an idea.

Ok, here's my guess. I'm very new to AE so I could be (and probably am) talking &%$@.

It's a composite of 2 separate shots. The t-shirt is already cut and is held together by a small strip of material. You can see this material curled up at the bottom of the cut immediately after it appears. The material is pulled down to reveal the cut. Probably by a thread of some sort.

In a separate shot Andrew slashes with the knife into thin air. Maybe it's my imagination or the fact that my eyes aren't what they used to be but I think I detect a few stray flecks of green spill around his outline.

So, position the two clips in space and time so that the cut appears as the knife passes It all happens in only 2 frames so getting them to match shouldn't be too hard.

I think I saw Tino's nipple. That classifies this video as a wardrobe malfunction and subject to an FCC fine.

I really wish you'd do a good tutorial about how you like to use Mocha. Since CS5, it seems the big thing and it's fairly easy to learn. I just like to see and hear how other "professionals" are using it - their preferred methods, workflows, processes etc. I've seen some great stuff by Dave Blum, but haven't seen many other tutorials on it, besides that. How do you feel about it? How or when would you use it compared to when you might use AE's built in tracking?

Why does everyone keep on talking about three takes and already cut tshirt. Didnt he clearly state that it was all one take and completley done digitally?

"But I wanted to do the slicing all in one continuous take using computer technology!"


So it has to be tracked.

I suppose if you wanted to be really anal with how accurate it is, you could have motion tracked a 3D torso to be EXACTLY the same as the actor's, made an nCloth shirt in Maya and ripped it that way.

...Fortunately, with simple scrubbing I can see where the second layer's being revealed :3

Hey boys and girls!
My opinion is that this footage was recorded with cuted t-shirt and it is only one take,just with cuted t-shirt!
stay good!

1) Take a picture of the front of the un-slashed shirt into photoshop, cut out what you don't need

2) Import the video of the actors (shirt is slashed), import the uncut shirt image

3) 3d layers, compositing, a wipe layer (quick), or a revealing mask so it looks, kinda like:

<===========|

4) I would add some movement to the layered uncut shirt though so it looks like its fluid.

July 18th, 2011 @ 1:02 pm
I'm gonna guess torn shirt is on the live footage and then painted back together and the Copilot logo tracked ontop of it to hide the paint out... then the tracked logo is taken out during the transition from not ripped to ripped.

This is all based on frame by frame viewing of the clip- the logo dances a little bit on the shirt.

I did something like this for a project/show I'm working on - it ain't easy (well relatively speaking). I found the plug-in ccsplit 2 works for this type of effect as long as you don't have to hold too long on the subject. A little warp mesh, bezier handles or liquify to match the movement of the original shirt movement and you got it!

Simple. Just make sure the knife is REALLY sharp and have the subject wear green body armor to key in the skin ;)

it's true the sound fx comes out before the slashing and the cut doesn't match the direction of the knife!

Only kidding! Great video as usual. Greets from England.
