Re: [FFmpeg-user] encoding video from png diffs

Hello everyone, I have another different, but related question. What format would you suggest for storing my screencast in? The resulting video is going to be 1080p30 and it needs to have an alpha channel (the input png's will use the alpha channel). The screencast is going to be overlaid at
