I've got recorded PowerPoint presentation (video podcast) - static slides, mainly texts, some static infographics with voice of the presenter (speech only). It lasts about 1 hour and encoded to .avi format using default parameters in Xvid occupies about 500 MB.
I want to re-encode it so it occupies as less space as possible to publish it as online video. I presume that the size up to 100 MB should be achievable (static slides + 1 hour of mp3). Could you please advise which encoder should I use (preferably Windows command line) and what are the best settings to achieve that?
