I just want to use it in blender in the video editing section and add it to a video that I was making. I finished it now, I rendered the video I was doing in blender, then put the video in after effects and placed the layer of the animation over it. I found out later by rendering another animation in after effects, premultiplied, that bender is actually pretty good with alpha. It didn’t have the black around the edges that were discussed in the video. Here is my finished animation that I wanted to add it to.

The subscribe animation at the end was the part I was having trouble with.

I don’t know how I would be inadvertently stripping the avi file extension, so I cannot properly answer that question. As for being able to place the extension after the name and have it be that extension I did not know about that. I just watched the video in your link and I guess my only problem was I was rendering straight and not premultiplied. The only problem is he didn’t explain how to composite straight in other programs so it doesn’t look like crap. So I’ll stick with premultiplied for now.

Yeah well every tutorial I’ve watched for cs5 or cs6 said to use quicktime and then put the selection in output module to alpha + RGB, but cs4 only has quicktime movie not quicktime, and quicktime movie apparently doesn’t have alpha + RGB. I did what they said in the tuts though and put on the output module preset lossless with alpha and it starts with the format “video for windows”. The channels under video output is set to RGB + Alpha and I change the color setting from premultiplied (matted) to straight (unmatted). I then choose “output to” and save it to the folder with the name I choose. Then I select render and wait for it to finish. Once it’s done I see it is the file extension “file” and is incompatible with all but one program on my computer (VLC media player which I downloaded specifically for these). When I do open them in VLC media player I can clearly see that the alpha channel is screwed up, if it even rendered an alpha channel (I can’t exactly find out because I can’t use the file in any video editing software). All the parts of the video where the opacity is low is now full opacity which is not what I want. This is what I did, do you know what I did wrong or anything?
P.S. I just went ahead and brought the video I wanted to put this stuff over into after effects and just rendered it that way and that video is done, but I would still like to know for future projects.

P.S.S. I tried rendering the video with RGB + alpha again later with FLV, TIFF sequence and PNG sequence formats and they had pretty much the same results. Maybe there’s something wrong with after effects?

Thanks, the presets were closest to what I wanted. Now I can look and figure out how they did it and try to improve it.

I can understand that, but my goal is to learn how to animate stuff that looks very real, and I can’t do that if I don’t even try and just go with the real stuff.
