So I’ve been doing some research and experimenting and discovered that turning the layer to draft quality makes the blur stop. I know this has to do with subpixel repositioning, but it seems that it could easily screw up the look of other effects and layers if I leave the final render at draft quality. Any ideas?

Dave,
I originally had that thought too, but because they are using the clone stamp, using paint on transparent does not work. It basically produces a blank frame.

No cameras in my shot.

I am not an expression wizard, but you can do the same thing without the use of a null. Basically, if you don’t have any other position animation on the layer you can animate the position of the layer in only the y position and then apply this expression (only the part in quotes) “loopOutDuration(type = “pingpong”, duration = 0)” What this does, is takes two or more keyframes (that should start at the beginning of your timeline) and loops them for the duration of your project. If you have other position animation that you have to worry about you can do it other ways. You can put a transform effect on the layer, and then animate the position on that in just the y and put the same expression on that. This basically acts as a null without having to have a null. Or if this is the only y position animation you have and you are in CS3, you can search for an effect called separate x, y, z. What this does is break down x, y, and z into separate effect controllers so they can be keyframed independently. Then you can put the y animation on the y property with that expression and animate the x and z separately. If you are in CS4, there is a switch to treat x, y, z as separate keyframable items without the need for this effect. If you don’t understand this, let me know. I know it was a lot to throw at you. Oh also, the expression above will go from point a to point b back to point a so it will animate for instance up to down to back up. If you want to just jump from B back to A at the end of the two keyframes, you just change the word pingpong to cycle. Its hard to illustrate by describing it, but if you test it you will see what i mean.

To answer your question, the chroma or gamma shift that used to occur is fixed. I did extreme testing on this, using scopes in both After effects (plugins) and fcp and there was a real gamma shift of a value of .2. This was fixed in CS3 or some iteration of CS3 and FCP6. Its been a while so I don’t really remember whose end this was on, but as long as your project is generated in CS3 or CS4 I think you should be fine. If you take an old project and open it in CS3 or CS4, you may still have the problem.

To make a folding object, you can divide a layer into masked out portions that border on eachother. Then set the anchor point to right at the fold or point on the mask that just touches the next mask. Then separate it into different layers for each mask and parent the layers to eachother so that each is parented to the next layer (or layer before depending on the type of fold). Then if you are doing a fold on x rotation for instance, set every other layer to have an expression with a multiplication of -1 on the x rotation property. Let me know if this is really confusing, haha.

For instance I’m not that familiar with node based systems, but know that if I were in fusion for instance, I could merge the red and the green and then use them as the matte.
-
Yeah, that definitely makes sense, and is one of so many options that you can do. I just wished there was a way to just put 2 set mattes on a layer or some other effect so that there wont be any effects on the rgb matte, and no precomping involved.
-
If I nest them, I will lose the add mode that I need to go to third clip that is below these two.

Unfortunately due to compositing, backgrounds, effects, etc. its impossible to build it twice.
