Whenever I approve or reject large upload requests I look at primarily at the run time of the video than the resolution.
If users want to upload high res, 100% quality, first-pass encodes, then they should get their own hosting and use the direct or indirect links.
Now that we have h.264 and aac audio codecs to encode with, it is possible to standard definition videos down to 10MB per minute of footage and still look good. Considering that fansubbers can manage to get fairly good looking encodes of full length, 720p shows under 250MB, AMVs should definitely be able to do the same for less than 100MB.
On a personal note, it always annoys me to see a 4 minute long video uploaded that is 99.9MB in size... Anyone that has been on the forums as long as I have should know I love high quality AMVs and like the technical side of video editing such as avisynth pre- and post-processing and video compression, but honestly there is a limit as to how much it matters.
The trick in compressing videos isn't to the make them as perfect to the original as possible based on the org's 100MB limit, but instead finding the perfect trade-off in filesize and quality while still maintaining very good quality. Until you can do that, you still don't know how to effectively utilize the encoding tools at your disposal.
btw, framerate doesn't really matter much when you are compressing with an
inter-frame codec such as xvid or x264 as the changes between the frames get smaller the as the framerate increases. The less change, then the less data that needs to be stored per frame. In the end, with the right settings, you can get a 60fps video down to roughly around the same filesize as a 30fps video without sacrificing much quality.
