With that information I could look again at my hosts, and at my expected number of downloads and figure out what sort or revenues I require to keep my shirt on my back.
Codecs are not equal, for example a DV-AVI is 14 gigs per hour, for comparable quality you'd need about 4 gigs for MPEG or 1.5 gigs for something like WMV or Divx. They each have their purpose though...
The bitrate required is largely dependent on the resolution. Each codec has sweet spot for a specific resolution. For example if you're using DVD compliant MPEG2 at 720X480 if you get above 8000kbps generally you're not deriving any benefit but just creating a larger file. Once you get below 4000kbps macroblocking will become an issue. At that point you are better off using a lower resolution. The sweet spot for MPEG2 is around 6000kbps, provides the smallest file while not degrading video with a lot of action.
Video of some guy sitting at a desk will require much less bitrate than something with a lot of action and movement.
Poorly shot video such as hand held footage, fast pans or zooms, lots of noise... etc. requires much more bitrate than steady footage shot on a tripod that is a very clean source.
Edit: FYI "gigs per minute" is well beyond full HD.
The properties are:
Resolution: 320X180 (for 16:9 video)
Total bitrate: 70kbps
File Size: 4MB
This was achieved by combining the stereo audio tracks and making them mono at 20kbps. It's not fabulous but WMA audio excels past other codecs at really low bitrates. This leaves 50kbps for the video which is very low for that resolution, the only reason it works is because the framerate was changed from 30fps to 10fps, by doing this you are removing 2/3's of the bitrate you need. This leaves it slightly choppy but overall considering the audience it was intended for its the best damn video they will ever see without having to wait for it. On a side note 15fps is not that bad at all and most people would never notice it.
