Just tell me what format (though anything much more exotic than .mov is probably out of my reach with my current software) and filesize criteria. The ships I've finished are the Earthling Cruiser, Chenjesu Broodhome, Ur-Quan Dreadnought, and Arilou Skiff, Ilrath Avenger (a WIP), Druuge Mauler, and Pkunk Fury (sort of a WIP).

OK, I did a quick test render of an old crappy animated model and put it on my site in .mov and .avi formats:
http://www.seankreynolds.com/uqm
Let me know what you can do with those two formats. If one or the other doesn't work, let me know and I'll see if I can get some software that'll convert it to something that does work. Once we have a format that's working, I'll do some renders of my actual SC ships.
What dimensions should these animations be, anyway? 640x480? 320x240? 800x600?

{Both .mov and .avi are container formats. They may contain media encoded using various codecs.}
You might as well be saying "blah blah blah" here.  I know what a codec is but not the details because I'm not a programmer and don't need to be a programmer. Just tell me what I need to do. 
{On my PC the .avi file plays, but the .mov file doesn't, but whatever lib we end up using could have totally different capabilities.}
I created the files on a Mac. The original export is a .mov file but I'm able to convert it to an uncompressed AVI easily. I'm sure I can find software to export it to other formats if that's what it takes.
{I suggest you just go with some common format which has an open source implementation or at least a codec that can be distributed and used with UQM.}
Such as ...? 
{As for the dimensions, we could probably display anything, but 640x480 is the resolution that is used by the game (at least what you end up seeing).}
Easily done.

Fot or not?

Based on this experience, I would go with uncompressed AVI.
Uncompressed AVI? You do realise that means hundreds of megabytes for a quick fly-by at any watchable resolution? Uncompressed AVI may be great as an intermediate format while working (i.e. as long as you don't have to transfer it anywhere else than your 200 GB hard disk), but you really don't want to distribute that on the 'net. Here's my plan:
My suggestion is XviD (a well-known GPL MPEG-4 implementation). The codec has been tried and tested on many platforms and there should not be any problems linking it to UQM (legal or technical). AVI seems to be the usual container format for XviD. Alternatively, we could use Ogg movie containers (.ogm) instead (we're already using libogg for audio). Theora is a less established codec but has similar capabilities and integrates a bit better with Ogg.
To encode video to XviD on a Mac, the easiest solution appears to be ffmpegX.
MPEG 1 layer 3 audio is the de facto standard, but as we're already using Vorbis, I suggest we stick to that. We can add audio separately, so I wouldn't worry too much about that.
As far as resolutions go, I'd suggest using 320x240 and 640x480. Most of UQM runs at 320x240 internally, with scaling and filtering to 640x480. 320x240 is acceptable for low-quality video, while 640x480 looks quite good.
As for bit rates, I'd use something like 800 kbps for the video and 128 kbps for the audio on the high quality version. 300 kbps for video and 64 kbps for audio should be enough.
Summary: XviD+Vorbis in Ogg or AVI container, 640x480 (800+128 kbps) for high quality, 320x240 (300+64 kbps) for low quality.
