@ron_houk @ashley hmmmm are they exactly the same version and configuration of ffmpeg? my first instinct is that maybe the Arch and Ubuntu package managers install different versions/configurations of ffmpeg by default (so maybe Ubuntu's "apt install" doesn't include a flag/dependency that Arch's does?)
@ron_houk @ashley ah, ok, yeah, I'm not familiar with Arch but there's definitely some funky licensing stuff with Ubuntu where they don't distribute a lot media codecs by default (are you making MP4s?); could be that ffmpeg isn't encoding things 100% because it's missing codec dependencies from the OS
sudo apt install ubuntu-restricted-extras libavcodec-extra
if that doesn't work you may need to find a multimedia-enhanced Ubuntu ffmpeg package, I think there's one out there
@ron_houk @ashley yeah, there's an "Ubuntu Multimedia" package on ffmpeg's download site, that would probably include a more optimized configuration of ffmpeg for your purposes than Ubuntu's default offering, you might want to install that manually if installing the third-party codecs doesn't work:
@ron_houk @ashley huh, sorry, nothing's leaping out at me from the command itself! I'm just stuck on what could make it work in Arch and not Ubuntu, but I can't think what encoding dependency would be different for ffv1/mkv. the mediaconch errors might be helpful, but Ashley would be better at reading those than me!!!
