I just download MSI Afterburner.
I got a few questions about some things.
1) What video compression should i use? There's uncompressed, RTV1 compression and MJPG compression.
2) What frame size whould i use? There's Full frame, 1/2, 1/3 and 1/4.
1. If you have the HDD space for it I don't see a reason not to used uncompressed. If you want to conserve HDD space [I'm assuming at the cost of while-recording CPU performance] just try either of those formats and see which one your computer does the best with.
2. I assume this would be 1/2, 1/3,..etc size of your in game resolution? That depends on what quality you want and how much HDD space you have. The closer to 1 you choose the better, in terms of quality, assuming I'm reading it right.
