Recording Issue

Hello all,

I am attempting to record a game in 240 FPS for slow motion purposes. My plan was to record the game with OBS in 240FPS then edit it with video software so it slows down 4 times for slight slow motion effect. What I am experiencing is that the game itself records the first few seconds of the video then freezes and resumes recording every 1-2 minutes, and then fully records the ending. My CPU was at 30% while playing the game and spiked up to 40% while recording. My GPU was at 50% then spiked up to 60% and the hardware encoder stays under 80%.

I tried 120FPS, tried 240FPS, tried adjusting a bunch of settings in the game, tried a bunch of settings in OBS, etc, but nothing works. Even 60 FPS freezes on me. When I record the game itself with nVidia ShadowPlay, it works flawlessly so that left me puzzled.

Any help is greatly appreciated!

Recording above 60fps is outside the supported use-case, and so is entirely at-your-own-risk. We cannot assist with it.

I am still having issues with 60 FPS. No one has helped me so far. Is OBS broken outright?

nVidia ShadowPlay works fine.
Windows 10 Game Bar records fine.
BandiCam even works fine with 60 thru 240FPS.

I'm confused why OBS is freezing up just trying to record at 60 FPS?

The log you posted showed a negligible amount of lost frames, so the video should be fine. Often it's simply the media player that is not able to play nonstandard videos.

However, you have some issues with your scene setup. Don't capture the same monitor with display capture twice, they stomp on each other (you have one in the "Desktop" scene and one in the "Sector" scene). It's also possible that display capture has issues if used with some game capture source running at the same time (your WoW scene). Keep in mind OBS is always opening and capturing all sources in all scenes, regardless if the scene is active or not. If you capture the same thing twice or more, only one instance will show an image and the others will be black or show a still image.

So for troubleshooting, cut down your scene setup to the bare minimum: one scene with the one capture source that captures what you want to record 240fps for slow motion. Nothing else. Try to make this work.

If you get this working, you can add sources one by one and see if one of the added sources make the whole recording fail.
