Resolution/bitrate : file size

[wolve999]

Hey all; I tried some searches but didn’t find much.


Sub just got the ATI 550 working (woot), but now I’m trying to configure the capture settings.

I setup a ‘custom1’ with 320x240 resolution and set the bitrate to the lowest possible (1500). But I’m still getting huge file sizes. (about 47MB for every minute, So that about 1.4GB for a ½ hour)

I’m would really like a much smaller size like maybe 300MB.

The 550 has hardware MPG2 encoding.

Also the 320x240 seems much bigger than it should; when running in WMP at 100% it takes up almost ½ the screen. And my resolution is 1152x864

Thanks

I don't know if you could get a 300Mb mpeg2 for a 1/2 hour show w/o it looking the old Superman game on the Atari 2600.

Something is also off on your encoding, as I get 1.5Gb files for the same length at 5600-6400.

There seems to be a bug in the 550 Pro support. The drivers dont seem to respond to the IAMStreamConfig interface I use for setting the bitrate etc. I'm investigating.
