Hi Andrew.
I am a great lover of your tutorials. I have watched almost all of them although I am a low income earner working for a dollar or two per day while i have a family. For now I don't have a computer to put into practice what I learn from these tutorials but I believe that one day they will be of great help. I love video production and i will work hard to accomplish my dream. thank you for your continued help. You are one of your kind. Once again thank you.
Oh. And by the way i would not mind a computer gift. I believe you have many ad you are in a position. I am in Kenya.

How hard would this be to do in reverse? Take a cloudy sky over, say, mountains or sand dunes and replace it with a completely clear blue sky?
Thanks!
Thanks!

Can someone let me know if the second part of this tutorial works in cs5.
I have imported the video.
User color correction, colorama to and grey it out.
Then add the adjustment layer.
Effects color corection Hue/saturation
Then create a copy of the original footage and drop the adjustment layer in the middle of the footage.
I can get the effect of tweaking as all I have is a black and white picture.
Help please

Great work Andrew. I did a 3 day shoot where we had to replace the sky in almost every shot. I did something very similar to the gradient background you showed in this tutorial. I added a layer with fractal noise to create clouds. This added to the realism and texture to the sky. And I could use the controls of the FN to match pans and tilts which would be hard to do with a flat image.

If you do not have the "mode, T or TrckMat" in your time time look at the bottom of your screen to the right of "Expand or collapse layer..." and you will see "Toggle Switches / Modes".
Hope that helped, it did for me

FANTASTIC. You are the best. Love your tutorials. No doubt you are a genius at this work.
In the future, could you please consider doing a tutorial on a sky replacement where the camera is panning about 180 degrees across a landscape (way to the left or right), and you have to attach a long new section to the sky / then blend the edge / as the pan continues?
You are an inspiration. I wish I had 1/100th of your knowlege.

Hello!
Thank you so much for all these great tuts!
But I noticed some of them are linking to missing file, and this one first.
Can you please check what's wrong? I hope I'm the problem, but it doesn't seem so. And well, I don't like to ask for, but in fact I need it
Hope you can do something!
Thanks again, and please forgive my bad english, it's not my primary language

Thanks so much Andrew for sharing your expertise. I wonder whether you have any suggestions for eliminating flutter around the edges of the matte caused by a panning shot? I would be happy to send you a peice of the footage. It's a real challenge.

Hey man this was great. I wish you could talk a little more about using it for effects though. Like in X-Men when Storm makes the sky all dark and cloudy, show how they do that, relating it to what you showed us here. Thanks man for your time and willingness to help.

Great job on the tutorials! They are a pleasure to watch. Sometimes you move too fast for those who are trying to track your clicks but I haven't installed AE yet so I am sure your speed will be just right...
Like it is a real pleasure watching these... and stuff...

thanks for another great tutorial!
but: what if the original sky isn't that shiny and say a little bit more grey/dark... the colorama effect doesn't work that great to key it out... what can i do??? (i'm not the key-out-master)

best wishes, mika

First off andrew awsome tutorials!!!Can oyu do a tutorial where you can explain how to put a 3d animation in behind live action footage...Like in transformers movie when optimus transforms and walks towards the kids...How did they composite optimus prime in front of the people!! I try to do it by drawing a mask around the people but it too hard and too long to move the mask to try to follow the motion of the live action people!! If you could could you do a tutorial of something like this!!!
