I partially understand what this bit does -y -ss 30 -t 3 -i in.mp4 (getting the first 30 seconds and generating a 3 second gif out of it).
$ ffmpeg -ss 30 -t 3 -i in.flv -i palette.png -filter_complex \ "fps=10,scale=320:-1:flags=lanczos paletteuse" out.gif vf fps=10,scale=320:-1:flags=lanczos,palettegen palette.png I found this answer and I made it work, however I couldn't understand how to adapt scaling & cropping. Then I started tweaking with mp4 to gif conversion, but when palette comes in, I couldn't fully understand what's going on. My question is how to achieve the same this code is doing, but for directly generating gif from mp4. I achieved that (cropping & scaling) from mp4 to mp4 with the below line, (so I can extract pngs with ffmpeg and use Imagick to make animated gif), but I believe there is a better way of achieving purely with ffmpeg.įfmpeg -i in.mp4 -filter:v "scale=300:ih*300/iw, crop=200:500:50:80" -c:a copy out.mp4
I want to scale it and crop it while generating.
I am trying to generate a gif from an mp4 video file.
