I certainly hope someone can help on this. I have been using my HVX pretty much only for shooting clips on a green screen. I use AE with Keylight to for the backgrounds. I would like to try to take it to a different level. I would like to bring in a video and map it to a plane in my 3D animation program in order to have fine details for objects in front and back, with my subject in the middle. Now, with stills it's fairly easy, just create and alpha channel in the TIFF and map the image on a plane and you have whatever subject you want in the 3D scene. I'm just not sure how to do this with a video.

Is there any way to export a video from AE that will maintain the transparency done in Keylight so that it can be mapped onto a plane to be used in my animations? Just to let you know, it is possibly for me to map a plane with a video so that it plays in the animation. I sincerely hope I don't have to do this the hard way, exporting TIFF sequences and creating an alpha channel and then bring in each one individually. I haven't done much exploring in AE past my present needs, so any suggestions would be greatly appreciated.

If I understand you correct just render out a QT animation with alpha enabled.

Maintaining transparency (alpha) on export is easy.

I use avi (Lossless with Alpha) setting or QT (Millions plus).

There maybe be animation settings that work as well.

Hopefully this is what you are asking for.

QT has always worked just fine for me. I believe you can even export tiff sequence with alpha.

It looks like the QT solution worked. For some reason, I never really saw the RGB+Alpha setting until mentioned here. Duhh. Thanks for your response, much appreciated.

Glad you got it figured out.

AEFX is a great program with a famous "long learning curve".

My learnng experience of it is that it kind of creeps up on you then suddenly it goes from WTF to do-able.
