Turn image sequence into video with transparency

Question

I\'ve got what seems like it should be a really simple problem, but it\'s proving much harder than I expected. Here\'s the issue:

I\'ve got a fairly large image seq

Answer 1

I know this topic is a bit old, but I am posting anyway.

FFMPEG with Quicktime Animation (RLE) or FFVHUFF/HUFFYUV will do.

• ffmpeg -i yoursequence%d.png -vcodec qtrle movie_with_alpha.mov
• ffmpeg -i yoursequence%d.png -vcodec ffvhuff movie_with_alpha.avi
• ffmpeg -i yoursequence%d.png -vcodec huffyuv movie_with_alpha.avi

You will get video files with transparency(alpha channel) preserved.

I have also heard On2-VP6 variation (Not the WebM-VP8 yet) can handle alpha, but I do not have their codec at hand.

This also works. - ffmpeg -i yoursequence%d.png -vcodec png movie_with_alpha.mov
