Can you upload some screenshots of your setup inlcuding the exact effect settings? That might help us determine the cause of your problem?
I can try that. However, it's pretty simple.
I set a key frame to spread out the cards, then 6 seconds later, set a key frame to bring them together.
This is the same setting for each comp I'm using.
As long as there is a still photo, the effect works fine.
If I put a QT movie in instead, the cards, between the two key frames,
jump all over the place. Put the photo back in and everything is fine.
Have tried different movies - same thing.
Well, if it jumps, the movie is used as a gradient input layer somewhere and the behavior would be perfectly normal, given that the pixel values change with every frame then. To be honest, I think you'r simply trying to do it the lazy man's way and have used your clip both as the layer the effect is applied to and then self-referenced it as the gradient, which won't work. You need a separate static gradient map.
Nope. Not the lazy way. I also tried this with a separate gradient layer and couldn't get anything to happen. The image simply got bigger when I increased to z value, it didn't break apart.
I also tried this on another Mac, using a different OS and the same thing happened. I need to use this for QT movies.. and I'm stumped. If someone could try this, I'd appreciate hearing about the result.
Maybe I did something wrong using the gradient. I created a layer, addend a ramp and dropped into the comp. Used that as the "gradient layer". As I said, when I then tried to increase the z position, the image simply got bigger... didn't break up. ???
