Just a short post as a reminder for myself. We do use a lot of ogv’s in our Narrow casting shows.
When you use ffmpeg2theora with a Linux or OSX kinda system you can convert a whole folder with video’s like this:
cd videofiles for file in *.avi; do ffmpeg2theora "$file"; done
Or with some more options, like video quality 9 (default 6, max 10), optimize files and put it some tag info:
for file in *.mov; do ffmpeg2theora --videoquality 9 --optimize --organization Formatics "$file"; done
Output:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'BTP mannetje en BTP3D model.mov':
