What kind of video recordin software do you use ? Im currently using Dxtory but the file sizes are ridicilous, 22gt, eventho I use low quality settings.

if you have pc and a video card that supports it. shadowplay is the best to use

OBS for everything.

OBS does well

Highly recommend OBS

I use a Razor Ripsaw with XSplit, and it works like a dream.

If you're suffering bad video sizes, download Handbrake. I did a speedrun of Inside using ultra high quality recording settings and it came out at 4.6gig (versus 600 meg at "good" quality). A quick encode in Handbrake brought it down to 1 gig with zero noticeable quality loss. Handbrake is unrivaled for compressing video size.
