RGBA is literally just RGB with alpha. It's for stuff like 3d renders with transparent backgrounds and whatnot to composite in videos. Pretty much useless for game recording.

YV12 is the fastest and smallest you're gonna get (though prepare for lossiness on red font text and other details), RGB is lossless. YUY2 is in the middle. RGBA is a waste of space.

And yeah, like >>1869663 said, use multithreading if possible. If you have a quadcore, try using two to give your game's performance some room. Your results may vary depending on your CPU.

Yeah, if you can't into 720p recording, try 480p.

Also, recording 30 or 60 frames per second is the norm. 30fps is the highest youtube goes, for example. If your rig can't handle recording in 60fps, nothing wrong with going to 30.
