Tips for video recording your games.
1. Make sure your using a seperate harddrive to record on that doesnt have the game on or windows on (something that isnt accesses when playing).
2. Make sure it is a fast hard drive, sata 2 or better and is defraged and smooth running.
3. When recording is finished you will need to compress it down from raw format. Since recording a game will be 2gig ish per home and 2gb per away game. Use windows movie maker. If your using win7 then it doesnt have it but you can get it from if you google for it like i did. Make sure you save it with a good bitrate so youtube can turn on HD mode which makes viewing all the more better for the others that are watching.
Here are my fraps settings. If its any help.
When recoding with windows movie maker or other, make sure the bitrate is 500kbps at the minimum (ideally you want 800+)
Note. I just tried video capture in xfire, it wasnt as smooth and 60fps like fraps was. Maybe codec issue i duno.
Not tried camstudio with sf4 yet.
