XviD overshooting target file size
Is there anything, other than user error, that could cause a 2-pass XviD encode to exceed its intended file size? In particular, will it overshoot if the target file size is "too low" for the video's resolution, frame rate, and amount of motion? I just had to set the target amount of video data to 280 mb in order to get the actual amount of data down to ~310 mb (with audio adding another ~40 mb for a total file size of 350 mb).

Dont know, but TmpGenc mpeg used to have a minimum bitrate that it would not go below (and would not tell you that it was going to ignore your settings).
(about 200kb/s I think, for mpeg)

So why are you using such an inefficient encoder?

Besides, this question has been asked hundreds of times in the last ~15 years. A simple google search ("xvid undersized site:forum.doom9.org") would have provided the same answers you got in this thread and a lot more suggestions to solve the problem.

The part where I tell it to aim for one bitrate and it gives me a completely different bitrate even though I'm not feeding it pathological content.

You could of course upload your source so one of us could try but that seems rather excessive for such a trivial problem. p.s. What version of xvid are you using?
