H.264 Codec Helps Long Video Be Small File Size Yet Retain Quality
In keeping with the philosophy that 90% of video is audio and the reality that no matter how little "video" there really is, it still eats space...
Challenge - 49.5 minute 10.5 GB trade show keynote DV file. At the frame rates I have seen on the Vlog scene to date, 3-5 MB per minute, that would be between 150 and 250 MB. Too Big.
So I figured out how to make Video Podcasts with the file size 763 kbit per minute and still convey all of the information recorded in only 37.8 MB. And this may not be as small as possible. The secret? H.264. Steve was right, as he usually is. It makes blowing down some humungous video to an internet transmissible Video Podcast size - retaining picture quality in spite of incredibly small data rates.

This is for voice only. Go 64 kbps stereo for music.
But keep Best and 32 kHz Output Sample Rate.
