HD .OGV (ogg) conversion
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.pyAfter 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!!
