I'm looking for a program that can convert videos. I've tried both Arista and Transmageddon and neither seem to work. Are there any alternatives or can someone help me with Arista or Transmageddon?
Transmageddon, a video transcoder written in GTK using GStreamer, has reach version 1.3 just a few moments ago. Initially released as 1.2, it was re-tagged as 1.3 after VAAPI encoding has been enabled. To see the full announcement, read this post on the Transmageddon blog.
This release fixes a big number of critical bugs, but brings a few new features as well.
