--- Comment #9 from Scott Petrovic <scottpetro...@gmail.com> --- That error log is actually pretty helpful. It appears your version of ffmpeg doesn't support the "-start_number" flag...which is what frame the animation starts exporting out. With a bit of reading, it appears some linux distros have a custom build of ffmpeg that isn't support by the ffmpeg team. See if you can get the regular version of ffmpeg this way (see the answer). https://askubuntu.com/questions/699502/ffmpeg-command-not-found Not sure if that answer will exactly work, but it sounds like you just need to get an "official" build of ffmpeg from a different PPA -- You are receiving this mail because: You are watching all bug changes.
