I know I'm not the only person here who encodes video.
Has anyone else here noticed that divx 5 seems to have a floor for file size when encoding at low bit-rates?
When I encode single files longer than 120 minutes, even with no audio, using vdub or tmpeg or even Premier, I end up with a file of around 800MB, no matter how low it set the bit rate or how much noise reduction or temporal smoothing (tools to make individual frames smaller) I do.
As an extreme example, I recorded a 2-hour and 1 minute MPEG1 sample of the blue screen my VCR shows when it has no other input - quite possibly the easiest thing I could possibly record. No audio at all. I encoded the MPEG using virtualdub on a couple of different machines using Divx5 Pro using different size-reduction techniques and a very reasonable 250kb/s bit-rate.
By my calculations, the file should've been about 225MB.
The smallest result I got was 760-something megs.
Anyone else run into this or anything like it?
