I have discovered that what I want to do can be done in Flash CS5. I can play the video in a time line under my animation. I need to be able to create an animation layer that can match the exact speed and location of action in the underlying video. For example we will say in the video there is a pen moving for 10 frames or so. In the animation layer I want to exactly match the speed of the pen with a line that is created at the tip of the pen (but in another layer).
See http://www.youtube.com/watch?v=Xme5-l8DU0g to get an idea of what I am hoping to be able to do.
All ideas on this are appreciated. I just need a general idea how to start.
very cute little animation! I loved it!
Not sure how it was made... but if I was to try do it..
At the very least, would have to shoot the video against a screen screen and then save the video with the alpha channel (transparent background).
Then after the video is rendered (as a .flv), embed the entire video into the time line. If the video is a .flv file you will get all the frames and you can scrub the timeline.
Then I would do the animation in a layer under the video. The hand would appear to be moving over the animation.
But the key will be to do the video against a green screen and chromakey out the green.
Best of luck to ya!
