OK it sstarting to make more sense to me now. Ive done some tests on Tiger with 3ivx.
I started off by using the detailed settings andrew provided. I then encoded the same footage at different resolutions and framerates, and with the quality slider on different values. Findings: In "Single Pass - Constant Bitrate" mode, the bitrate you specify is just an absolute maximum its allowed to use, not the bitrate thats actually used. The actual bitrate is decided by 3ivx, and it changes depending on resolution and framerate. The quality slider didnt seem to change the bitrate. So even when i put 6000 in the box, I got a file that was more like 600 kbits. It effectively ignored the 6000, because its such a high bitrate that no part of the video was in danger of 3ivx trying to encode it at a rate higher than 6000 anyway. When I put a really low value in the bitrate box, 100, it used that as a maximum bitrate and of course the footage looked awful. Some examples of what bitrate 3ivx footage ended up in during my tests: 960x540 25fps = 3800 kbits/sec 480x270 25fps = 1265 kbits/sec 320x240 25fps = 846 kbits/sec 320x240 15fps = 602 kbits/sec Hope that makes some sense, I will test other 3ivx modes later.
