  HD .OGV (ogg) conversion

  Posted by Sj Miller on June 27, 2013 at 2:52 pm

  Anyone know of a good way to convert .mp4 footage into ogv? The only free solution I could find was Miro video converter

  It produces really bad results, however I did find that this helped:

  
  “In this directory/Terminal:
  cd /Applications/Miro Video Converter.app/Contents/Resources/lib/python2.7/mvc
  Edited this file:
  open -e basicconverters.py

  After these lines:
  class OggTheora(converter.FFmpegConverterInfo):
  media_type = ‘format’
  extension = ‘ogv’
  I replaced:
  parameters = ‘-f ogg -vcodec libtheora -acodec libvorbis -aq 10’
  With:
  parameters = ‘-f ogg -vcodec libtheora -c:v libtheora -c:a libvorbis -q:v 4’

  Then ran python -m compileall . in that directory in Terminal.app.

  Then I quit and re-started the Miro Video Converter.app … Now I get better quality OggTheora …
  (I actually also replaced ffmpeg in the Helpers dir with my own binary, but I don’t think mattered, as I had the same problem until I changed the config.)”

  Although there are still no real options for customising quality… anyone know of a good alternative?

  Thanks

  I found a couple of things.
  A QT Component:
  https://xiph.org/quicktime/

  And a self contained application:
  https://v2v.cc/~j/SimpleTheoraEncoder/

  I found that, going from here:
  https://en.wikipedia.org/wiki/Ogg
  to here:
  https://commons.wikimedia.org/wiki/Help:Converting_video
  Then here:
  https://wiki.xiph.org/TheoraSoftwareEncoders
  I hope they work for you.

  You see?
  Both have learnt something new.
  I’ve never heard of that kind of files or those applications.
  Google search engine rocks!!
