One of the things I really like about RHEL/@CentOSProject is the ability to choose from 3 different versions of various applications. It's a nice feature (and great for developers).
.@debian is conservative, and so is RHEL/@CentOSProject, even in the form of Stream. For the kinds of uses I have, Stream could really work.
I used ffmpeg on the command line to convert an API video to MP4 so I could upload to Twitter. Very easy — anybody can do it. (I Googled.)
