The H.264 codec in the G1 is baseline profile Level 1.3. Maximum frame size is 480x320 (happily the same dimensions as the screen). Recommended maximum bit rate is 384Kbps. Maximum frame rate is 30 fps. It does not support B-frames (consistent with baseline profile). If you stay within these bounds, you should have good performance.
That said, with a good encoder, you can push the bit rate a bit higher. The important thing is that it not be too bursty, the decoder can handle a few frames at double the bit rate, but eventually it will fall behind. I've even had the audio track screw up when I pushed it too hard.
