Question about target FPS for recording with OBS
Posted: Mon, 22. Apr 24, 02:41
Specs: My system at the moment is CPU bound. I have an RTX 3060 12 GB with an i5 7600 on a B-series board (soon to be upgraded to an i5 1300 and a Z-Series board) and my monitor is a 144 Hz 1080p screen.
I have OBS set to record at a bitrate of 5000 kbps and a constant 30 fps but with the 6.20 update and tweaking some mod settings I am able to reach 50 fps in game (with dips to between 32 and 40 in moderately busy sectors). I understand that recording at a constant 60 fps is obviously going to make the file size larger (though I use nvenc_hevc to offload the work to my GPU) but what happens if I set the recording to 30 fps and I see several minutes of game play at 40 or 50? I realize that extra data will be "lost" but forcing a constant 60 fps would simply be duplicating frames.
So, ignoring file size, would 30 fps with occasional discarded frames produce a smoother / better looking video than 60 fps with often duplicated frames, considering the duplicated frames are not an even multiple of 30 fps (eg: 50 fps only needs 10 duplicated frames to reach 60 fps).
NOTE: I am not streaming, just recording so I can later look for some fun screenshots (maybe).
