QT 5min 30M which settings?

Academic conferences insist on QT .mov files for video submissions for online submissions.
Two constraints: not longer than 5 minutes, not bigger than 30 meg
I can get decent results with .wmv but I have not found a codec/setting that looks as good using QT with Vegas.
The content is locked down shots of hand held devices mostly, not much motion but a lot of texture.
Reviewers will watch theses videos on laptops and desktop computers. No streaming is involved.
I have been using QT's MPEG-4 codec but I am having trouble getting results smaller than 70 meg with a 4 minute video.
Ideally I would like to stay at 720x480 30 hz.
Would QT pro help?
thanks in advance

Vegas' default keyframe settings for QT are goofy. The result of using these default settings is a huge file with mediocre quality.

Set keyframes to 250 or so, that should do the trick for you.

There is a program called Sorenson Squeeze that will deliver the MOV file size and quality that you're looking for.

I have had Squeeze since a long time also, but the difference between the default Vegas QT setting and what I suggested is far far greater than between my suggested setting and Sorenson's different software.

I am just suggesting he should try first with just modifying the keyframe setting, it may save him the $449 for Squeeze.
