Recordings stuck @ 856x480 mp4

[Zerreth]

Ever since last update I cannot record anything other than mp4 @ 856x480. No matter what my settings are.
Changing output to AVI, changing framerate, resolution, enabling Hardware Acceleration... They all don't have any effect.
Reinstalling didn't fix it. Are there any preference files that I can delete to resolve this ?

I found the solution: force 30bit/pixel was on under general settings. Turning it off fixed everything.
