After Effects will not use the GPU to accelerate the ray-traced 3D renderer when exporting through Adobe Media Encoder or when serving frames to Premiere Pro through Dynamic Link.

I agree with Alex.

Are you asking for someone to help you to recreate this kind of animation? If so, what exact part are you having trouble with?

As Tudor says, use the YouTube encoding presets from Adobe Media Encoder.

Joe is right. I recommend starting here:
https://blogs.adobe.com/aftereffects/2010/04/roto-brush-in-after-effects-cs.html

It sounds like you’re reaching the end of the Roto Brush span. Read/watch the materials that I linked to for details about what that means and what to do about it.

Yes, it should be functioning correctly in AME CS6.

If not, please submit a bug report:

If you need to move this piece of metadata (called the ‘moov atom’) to the beginning of the file, you can find plenty of free utilities online to do that for you.

The only difference is whether a specific piece of metadata is at the beginning or end of the file. This piece of metadata is at the beginning of the file in movies created by recent versions of Adobe applications, so there’s nothing more that you need to do.

If you’re playing back from your computer, you can use a codec with less compression, such as PNG in a QuickTime (.mov) container. The limiting factor there will be disk speed, so be sure to test the output.

The H.264 codec was designed only for certain kinds of video, and so it has some constraints that are being enforced here. I’d recommend using a video codec that doesn’t have these constraints.

Tell us in more detail exactly how you’ll be using this video, and maybe we can recommend a better choice.

Yes, you can interpolate between paths, such as from one mask path to another or from one shape path to another. Just set keyframes for a path property, and interpolation will happen between the keyframes as with any other property.
