Xconvert > does not seem to be it. I use ffmpeg for video scaling. I wrote a blog entry on it, mostly to collect my own thoughts for future refence: https://qaz.wtf/qz/blosxom/2025/01/06/on-ffmpeg Since then I've added an "adjust compression" line to some of my scaling jobs: -c:v libx264 -b:v 2M -c:a aac -b:a 192k It goes somewhere after the `-map 0` option and is incompatible with the `-acodec copy` option. For thumbnail purposes, I suspect you might want smaller numbers than "2M" video rate and "192k" audio. Elijah ------ needed a few years to become comfortable with ffmpeg command line
