I've been shooting HD video of birds for 2 years now — 1 year with a Sony HDR-HC1, and another year so far with an HDR-FX7. However, I'd not posted any of my footage; my main excuse was, I didn't know a good way to deliver it in HD rather than down-converted SD.
I'd like to finally start posting clips now. I've begun by posting an American Golden-Plover clip, in what I would consider semi-HD. This is intended to share a rare sighting and allow the bird's jizz to be fully appreciated, but it is also very much a test post to see if posting in HD is feasible.
The main test here is if an XviD-encoded clip of 960x720 or higher at 60 fps can be viewed on a multitude of systems. On a PC, installing ffdshow should do the trick (it's what I use for playback). On a Macintosh, this download should do the trick:

It's 30 seconds and 30 MB. Perhaps that's a tad excessive, but since this is a test, and since I intend to post more videos if this goes well, excessive is good. The compression ratio is low enough that the video quality is virtually the same as the source on tape (or better, because the source was effectively a handheld digiscope shot and very shakey; the posted video has been run through Deshaker).
