I have been told its because OBS is capturing at a variable frame rate and need to be constant frame rate, i was under the impression that OBS always used constant frame rate?. Sometimes right after starting OBS the preview window shows only 30 fps, but if I close OBS and start it again I get the situation I wrote about In the Advanced section of the OBS settings, there is a Network area. 000 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Thanks a lot, i was recording Genshin Impact footage, with CBR, and 95000 kpbs, it looked really nice, though the files were around 500mb, for around 40 seconds of footage, i switched it to CQP, i tested with 16, 22, and 18, 18 seemed to have a very nice look, and the size was more than halved as before, that will help a lot, to know what quality its fine, to edit on If I could just change the frame rate mid-stream that would be great, but the option is greyed out once I've started streaming.
