OK, so completed shooting about 8 hours of video at the tournament and wanted to report back. First off, the quality of the video coming out of this Sony camera is excellent. I ended up picking the highest setting and 1080p, and was able to get 4 matches on a 64G card. The knock-off Chinese 8 hour battery also handled it fine. This little tripod also proved to be perfect for the task. It was light enough and compact enough that I didn't really notice it added to my backpack, and it was very stable. My camera actually took a hit from a shanked ball and it didn't fall over, though the camera ended up pointed in the wrong direction. I can live with that.
Because my MacBook Air hard drive doesn't have a ton of empty space, I offloaded the video files to an external drive while on the trip, and processed them when I got back. As it turns out the AVCHD, is extremely high quality, but a bit of a pain to deal with on a Mac. The files play beautifully on a Mac. But, you can't deal with them in iMovie in any way that I've found. Supposedly they can be imported, but I think because I did 1080p, that doesn't work.
So what I decided was that I'll archive the large AVCHD files on my NAS so that if I want to play them back in all their glory I can go to them, but for playback on my TV I used the Elgato h.264 Turbo software/hardware to convert them to m4v files, which I was also able to upload to YouTube for the girls to see. I think that is also sufficient quality to send to coaches, but will still investigate if I can find away to edit the AVCHD files without losing any quality.
So overall I'm quite happy. I spent under $500 on all this stuff and got a kit that is very compact/lightweight and can do very good quality video while I'm running around taking photos with my Canon gear.
