I know from this page that I can record video with RetroArch, I really dig the lossless quality. But two issues, will this option be included in RGUI for the next RA v1.1? And second, it says it records at native resolution, but I did a test and recorded at display resolution, without shaders. Using this config: http://pastebin.com/Azpjnq5m (works nice without config). With shaders it run very slow (although file played fine). Anyways with shaders probably native resolution isn’t possible, since shaders need 2x, or 3x resolutions to show fine if I’m not wrong, guessing here.
By default RA will record at native resolution, to record at a higher resolution, use --size then specify WIDTHxHEIGHT
