I know everyone recommends doing a Two-Pass on all video as it provides better quality, since the first pass, the encoder logs what frames need higher bit rates and other wonderful stuff. However, I always assumed Two-Pass was meant for fast moving frames, and provided smoothness rather than quality. This is something I've been Googling for a while, and haven't found an answer. Quality aside. Now picture this: I've recorded a Formula 1 race. Lots of movement, and particularly when the camera follows the cars round corners. Will doing a Two-Pass eliminate frame stutters? I use a typical 1000 kbps bitrate for all my encodes, and I see little quality difference between One-Pass and Two-Pass, and I can't actually see any improvement in smoothness of the frames which is what I'm more concerned about.
