Excuse me for my bad orthography, my native language is spanish.
I have a short time using blender, so this is giving me a real headache.
I’m ussing Blender 2.58.1, and I tested different video formats to make a video file with alpha (transparent) channel in the background, to put this animation in Adobe Premiere, and place it over other stuff.
When I import the video files to Premiere, them appears with a gray background, so it’s completely useless to me.
I saved the animation stripped in .PNG files, with the hope of join all of the png pics on a single video with alpha channel with VirtualDub… ok, when I open the first pic in VDub, it detects the entire sequence, I set the fps, but it saves the video with that damn gray background… so i though that VirtualDub doesn’t support Alpha channel…
I tested the stripped .png pics on Premiere, and effectively they have the alpha background.
I readed somewhere that older versions of Blender support Quicktime’s .mov format, and with that (or those) version(s) I could save my video in .mov format and reach my objective.
If you know of some software to join .png files onto a single video and preserve alpha, or another way to render from Blender my animation with the alpha background to open it on Adobe Premiere, please… PLEASE! let me know.
