Hey! I'm trying to make the image I have of someone shooting the ball look like they are actually shooting the ball. I masked out all of the unnecessary part of the picture I don't need and now I am left with only the arms. I will attach a picture. I tried to use the puppet tool, but it often distorts the image in a creepy way. Thanks!
Save yourself a lot of grief -- shoot the real thing.
Dave is 100% correct - much easier and much faster fill be to shoot that kind of footage. If you have proper skills and a lot of time for rendering and preparation you can do that with any 3D software like Maya, 3dsMax, Cinema4D etc. You can try to do some kind of small and small and gentle movement of what you've prepared but you will never be able to animate one static photo of two arms to full motion 3D movement of those arms - with bending and all.
Depending on the style you're looking for you may be able to fake it with puppet pin. It will look fake. The key to making it work is transparency and layers.
