Obs studio recording performance hit4/9/2023 If you want a flat 120 FPS, enter 120 and 1 (120 divided by 1 equals 120). In Settings > Video, set FPS type to Fractional. Using a value of 0 will use a keyframe interval of 250 frames, this is preferred if you're recording at more than 250 FPS. While this shouldn't break the recording, your video editing performance may suffer greatly with certain video editing applications. Slow storage may erroneously show up as "encoding lag", or corrupt your videos without any error messages.ĭo not use excessively long keyframe intervals Even if the storage device itself is fast, USB or networking overhead might still give you headaches. Just don't do that, write to local disks. Start with a high QP value (like 30) or VBR, then adjust your settings when you make sure that your storage device can keep up and your recordings don't come out corrupted.ĭo not write to network disks or external (USB, etc) storage H.264 is very inefficient at high frame rates using CQP may result in significantly higher bit rates than what you're used to. Very risky, and almost no quality gain on Turing and Ampere cards. On Pascal and older NVENC chips, this may improve quality, but NVENC usage and GPU usage will at be least doubled. Common mistakes and other things to avoidĭo not use the "Max Quality" NVENC preset (Someone in the obs-studio Discord managed to get it to work. The AMD encoder appears to be capable of 240 FPS recording on an RX 480. (Tested using my own hardware as well as some other people's hardware) Meaning, a GTX 1050/1060 should yield 260, but a 1080/1080Ti should yield double that, ~520 FPS, as they have two NVENC chips. Pascal NVENC should be capable of ~260 FPS at 1080p, per chip. Update : Looks like someone had issues with the "Quality" preset with a 2060 Super at 1080p 420FPS, changing preset to "Performance" and disabling "Psycho visual tuning" fixed this. Turing NVENC (GTX 1600 series except GTX 1650, RTX 2000 series, RTX 3000 series) should be capable of ~630 FPS at 1080p. Unfortunately, neither AMD nor NVIDIA provide specific information about their throughput, and that throughput may also change depending on what else you're doing on the computer here's some information I was able to collect: Hardware encoders are not infinitely fast. NVENC crash (stuck "Stopping recording.")ĥ. How to access frame rates in excess of 60Ģ. "Minimum system requirements" and hardware encoding throughputĠ. Grab MSI Afterburner and RivaTuner Statistics Server from (installer includes both) if you need to collect performance statistics. I'm operating under the assumption that your machine is already capable of recording at 60 FPS - if not, get that fixed first with the help from OBS Studio Discord server or any other means of your choosing, then you can try to push for a higher frame rate. A collection of troubleshooting advice snippets to help you record at 120, 144, 240 and higher frame rates, assembled by me, Nakajima Megumi#7432.
