if I do it in a single zscale filter instance, Im hitting issues that the zscale implementation inside of ffmpeg has no way to convert to RGB. Then add filters for fading out into the previous command: ffmpeg -i input.mp4 -vf fade=in:0:d=5,fade=out:595:d=5 -af afade=in:0:d=5,afade=out=595:5 output.mp4Īs in and 0 are defaults, you may shorten the command to ffmpeg -i input.mp4 -vf fade=d=5,fade=out:595:d=5 -af afade=d=5,afade=out=595:5 output. But now, the information of what it is is known in the ffmpeg filter chain, so the next zscaletlinear will now work (and convert it to gbrpf32le apparently). ffmpeg -i in.mp4 -vf 'fps1' out04d.png would work.
fps is not even an option so ffmpeg -i in.mp4 -fps1 -vsync 0 outd.png cannot work.

You got for example the timestamp 600 - 5 = 595 (from your 10-minutes long clip). It is no longer needed for the FFmpeg AAC encoder unless your ffmpeg cli tool is really old, and if thats the case please update.
5 s - from the total duration of video or audio (you may find it with FFprobe). see the answer of the question FFmpeg read, ignoring remaining -vf options: Use ',' to separate filters.įor fading out you have to subtract the time of fading out - e.g. Only '-vf fade=in:0:d=5' read, ignoring remaining -vf options: Use ',' to separate filters use: ffmpeg -i input.mp4 -vf fade=in:0:d=5 -af afade=in:0:d=5 output.mp4įor 5-second fading in from the start of your clip. Fading in is no problem, because you start from the timestamp 0 (or from other known timestamp or frame number), e.g.
