NEW TUTORIAL: Speed Particles

In this new 20 minute tutorial we will create a dynamic particle system that emits based on the speed of a layer. In other words when the layer moves fast enough, the particles go flying! Creating automated animation has never been easier!

I knew I would have 2 tutorials done in the same week! Mintues to spare.

Do you want a longer, stronger, more flexible love life?
Well then get TWITCH from yes with TWITCH
you too can have what you see your neighbors having
through your bedroom window between 7-9 pm on thurs +
fri nights, and sometimes on tuesday but not during the fall because
that's when new seasons of their favorite tv shows come out
and they get divorced! Yes.. buy now!

Haha, great clips mr. kramer
July 19th, 2008 @ 9:53 pm
I actually understood the expressions! I'll use that!
Thank you AK,

Thats Fantastic Andrew !
Very Very Nice ;)

Bye ;)
July 19th, 2008 @ 11:48 pm
awesome tut.. but of cuz all the tut s are great.
July 20th, 2008 @ 12:26 am
its looks sweet... i never realised this effect would be so simple...i mean i thought you need some sophisticated 3d program to achive this...
i guess the saying is right ..

"You can do anything in after effects, if you know how.."
July 20th, 2008 @ 12:43 am
Thanks for your effort.
July 20th, 2008 @ 1:27 am
Love this effect. Thanks for the tutorial.

It would be awesome to see more examples of using expressions to drive complex animation, particularly stuff that's tedious to do by hand (e.g. imitating real physics - weight, momentum, collision etc.).
July 20th, 2008 @ 1:30 am
July 20th, 2008 @ 1:32 am
wow, that looks 3d ,gonna check it out...
July 20th, 2008 @ 2:31 am
Very Pretty.
July 20th, 2008 @ 2:32 am
Fabulous :D

I think that we can create particulars for a magic wand with this, in following a null object.
July 20th, 2008 @ 3:12 am
I was doing this in 3ds max cuz i didn't know how to achieve the effect in After Effects. >_> Thank you Mr. Kramer! It's way easier now (:

nice! last minute tutorial this week
July 20th, 2008 @ 3:26 am
Hi there Andrew, all your stuff is tremendously helpful. I have a doubt, i see that in this tutorial when you wrote your text, the anchor point was set automatically in the middle. In my case the anchor point is always on the bottom left of the text.

May you please tell me how I can fix that so my anchor point can always come up in the centre of text.

All the best,
July 20th, 2008 @ 3:35 am
Hello Mr. Kramer, thanx for all these valuable tutorials. Can you plz tell me from where you took training for VFX & 3D. I also wanna buy your DVD's, they are very valuable. plz reply

July 20th, 2008 @ 3:35 am
just 1 thing... u had particular registered as an unlicened demo and u didnt get the watermark? any response?
July 20th, 2008 @ 3:39 am
I like this one, but where is the tutoril with 3D text in After Effects?
I thought you would make such a tut!!
From the example: Catching Up, with the text: TO CATCH AN EDITOR
July 20th, 2008 @ 5:18 am
happy birthfay!
from argentina!
July 20th, 2008 @ 5:59 am
Really big thanks to you Andrew!
July 20th, 2008 @ 6:15 am
Thank you Andrew, this one definitely sparked some ideas :) Love it!
July 20th, 2008 @ 6:54 am
July 20th, 2008 @ 7:07 am
July 20th, 2008 @ 7:33 am
oh man...where do u get these ideas from
Rock on :p
July 20th, 2008 @ 8:08 am
great tutorial, very cool effect, that speed expression is awesome. i saw in the sample there was light added, is that an expression also?
July 20th, 2008 @ 8:21 am
Great tutorial!! Thanks AK!!!
July 20th, 2008 @ 8:46 am
Thanks for the tutorial as always .
July 20th, 2008 @ 9:04 am
Excellent tutorial. Good stuff man. I'm looking forward toward your next Advanced DVD :)
Mr Lopez
July 20th, 2008 @ 9:12 am
Where do you get these amazing SFX Mr. Kramer?
July 20th, 2008 @ 9:50 am
I must say i was a little disapointed that it wasn't about 3D text; until i watched it and realized how awesome expressions really are (and how they seperate the pros from the users).

Thanks a lot Andrew, i'll never judge a tut you drop ever again (no pun intended).

hmmm, im using AF CS3
but i dont got Effect>Trapcode>Particular
i dont got the "Trapcode"

what to do?
July 20th, 2008 @ 11:47 am
Excellent Andrew...great tutorial....
Scott middleton
July 20th, 2008 @ 12:12 pm
Hi Andrew
great tutorial as always but I was just wondering about the background texture you used did you photograph it yourself,
or did you get it from somewhere?
Alex Lopez
July 20th, 2008 @ 12:25 pm
Great job! This looks awesome!
July 20th, 2008 @ 12:40 pm

can say more, just look at my video for you:

July 20th, 2008 @ 1:06 pm
First many THX for this new tutorial!

But is there a big difference when i use the Text Layer for the emitter Type ?

MFG Warti
July 20th, 2008 @ 2:37 pm
You come up with the greatest tutorials. You make what seems so impossible like coding a cinch. You also make it possible to understand and use in other projects. Thanks again cant wait for the next one. I check this website everyday and have bought most of your products
Pete Valcanas
July 20th, 2008 @ 2:49 pm
Another great tut! I especially like how you sync your sound effects to the animation, it adds a lot of punch, I keep trying but never get it as good.

Thanks again,
July 20th, 2008 @ 3:06 pm
Nice one!

Its all about expressions today...
July 20th, 2008 @ 3:08 pm
Hey Andrew

Amazing, these two tutorials.
I have one question, how can I use particle world instead of Trapcode Particular. Because I dont have that plug in.

July 20th, 2008 @ 3:12 pm
Speed expression!
Andrew I thought you might do something like this, although I did not think it would be this cool!

Thanks man, you can have my last beer.
Conor Maher
July 20th, 2008 @ 3:20 pm
I'm going to go with WOW!

Very cool effect, Thanks!
July 20th, 2008 @ 3:29 pm
Warti, you can use the layer as the emitter but the key is to only emit particles at certain speed...
July 20th, 2008 @ 4:06 pm
I think that i'll use twitch to create something very very cool with this technique
thanks andrew

try experimenting with twitch to see if you come up with something cool.
July 20th, 2008 @ 4:21 pm
Andrew, excellent stuff. Just out of curiosity. How do you know someone would fall off a car at 80 MPH??? Have you been experimenting with Sam again? Or was he trying to hang out with you and you were trying to get away and that was the speed you reached when he fell off the hood?
July 20th, 2008 @ 5:41 pm
btw where did you get that texture, i can't find it in the riot gear collection or in evolution
Kim A. Strandli
July 20th, 2008 @ 6:02 pm
@Toni Smosh:
Trapcode Particular is a stand-alone product from
I doesn't ship with After Effects CS3.

Great tutorial!
July 20th, 2008 @ 8:18 pm
Hey Andrew,
I would love to see more tutorials with Particular you know there are some incredible results to be had. I am exploring Trapcode "Form" at the moment and playing with the audio map's very very cool.
I'm loving this use of expressions for this example btw.
July 20th, 2008 @ 9:14 pm
Congratulations for the 70th tut Andrew , this one is very nice ! Keep up the good work !
Dustin James
July 20th, 2008 @ 10:11 pm
@ Dan

Andrew plays around in AE with ideas and things that he does in his time and occasionally shows us what he 'might' make a tutorial out of when he gets time.. what happens is that meanwhile he keeps playing with new things.. and decides to make other tutorials.. (that is what I think happens and I've been here a little while.)

@ Andrew

THANK YOU! I am really enjoying these expression tutorials because they are extremely useful for numerous things! I think you've mentioned a book or two about expressions but I don't remember on which blog/tutorial. Could you maybe let me know about your personal favorite?

QUESTION: Why do/did you choose random numbers like 29 in the 29*S part of the expression? Is that a number you found worked for you, or do you just like random numbers?
July 20th, 2008 @ 10:17 pm
awesome tutorial. Ahead of the curve as usual. Keep it up
Andrew Kramer
July 20th, 2008 @ 11:23 pm
Dustin, 29 seemed to work from earlier. Particles rendering was fast and it didn't seem too sparse. You're pretty much right about the other stuff too...
July 20th, 2008 @ 11:26 pm
I'm starting getting expressions and they are so cool!

Thank you for all your great lessons.
July 21st, 2008 @ 4:03 am
I like this idea. One question (and I haven't tried it yet) is that I'm suprised Andrew never showed an example of using TWITCH to generate movement rather than using wiggle. Can you not get the speed from having added twitch?

I think it would be a great 'shake the drips off' kind of effect...
July 21st, 2008 @ 7:58 am
Your tutorials rock. Great work!

By the way, those '{ }' are also called curly braces.

July 21st, 2008 @ 8:59 am
Andrew! Very cool idea and realization is also cool. Very beautifully!
July 21st, 2008 @ 5:46 pm
hello I am having a problem with the render my particles do not apears at the final render! why??? please help! (I am not following the tutorial is just some inspirational results from the tutorial!)
July 22nd, 2008 @ 8:16 am
Hey, great tutorial, i was wondering where u got the background texture from? Or how i could get my hands on it :D

thanks, Matt
July 22nd, 2008 @ 11:42 pm
Hey thats wonderful tutorial I am really thankful to you for such great tutorials but I kindly request you if you could come up with wire removal tutorial in after effects it would be really graet.

Thank You.

Hi all,

I don't know how many of you know but here is a great resource textures that can be used for such backgrounds.

July 23rd, 2008 @ 4:55 am
texture is sadly not on the riot video copilot
July 23rd, 2008 @ 6:50 am
@ Kevin J

wow thank you,
that's realy a great resource!

July 24th, 2008 @ 7:17 am

Excellent use of expressions! It made me think of an great movie idea. We could plant this bomb on a bus and when the bus goes faster than 50mph, the expression could make the bomb go off. Maybe Sam and Sandra Bullock could co-star? Anyway, great job as usual!
Jake Bartlett
July 24th, 2008 @ 5:44 pm
Thanks for this great effect, I'm putting together my first motion reel and this works great for titling. I also just purchased the evolution pack and have been experimenting non-stop with everything in it. Thanks again!
July 25th, 2008 @ 1:23 am
Thank you! You're just GREAT! Whoew!

July 26th, 2008 @ 1:45 am
This is such an awesome tutorial. I will name my first born VideoCopilot in your honor Andrew and call my wife dot pest, I mean, dot net again in your honor.

Cheers for all the hard work
July 28th, 2008 @ 7:04 am
This stuff is great. Thanks Andrew!

One question. Is there a way to get a similar effect to 'starglow' with AEs native tools? Thanks.
September 19th, 2009 @ 2:09 pm
How i get the texture that you use?
December 2nd, 2010 @ 10:14 am
Looks beautiful.

@Diegatxo, I think that texture is in Riot Gear.
