So what I did to prepare for tomorrows game and recording, is that I recorded one full terrorist hunt mission... It was me alone, it took 7 mins and 41 secs... it recorded (in HD 720p), with 6.85 GB's of hard drive space...
I tried converting it in 3 ways...
1. With the default (for my PC settings) in Movie maker, it converted to 640x480 at 215 MB's of space.
2. With the Xbox 360 HD settings in Movie Maker it converted to 1280x720 at 397 MB's.
3. and the one I may have to go with, it's a good image but not great, especially the distances. I converted it with DivX and it re-sized to a manageable 62.7 MB's.
I could probably take just the highlights of a mission to make a better but bigger file... anyway, at least i can record... now to best convert, edit, and share with you guys.
