Question / Help Troubleshoots OBS Video


New Member
Yo guys !
I'm using OBS Studio to record some videos...
But when i record a video, the video quality is sometimes very, VERY bad... (here is a footage -> [At the start of the video, the video quality is very bad, and at the end, it's the normal video quality)
I'm recording in 1080p60,
Here is my OBS Configuration:
- Video (
- Output >> Recording (
- Advanced (
Best regards :D

You are badly overloading your machine, and the AMF encoder generally provides lower quality at the same bitrate than QSV (QuickSync), NVENC or x264 (CPU) encoding.

08:38:55.598: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 16150 (20.0%)
08:38:55.600: ==== Recording Stop ================================================
08:38:57.825: Video stopped, number of skipped frames due to encoding lag: 67042/80770 (83.0%)

"Rendering lag" means you're overloading your GPU.

"Encoding lag" means you are overloading your encoder, which in this case is also your GPU.

1080p60 is not a realistic target for all users, especially on a single machine setup that is a laptop. You may need to choose between 720p60 and 1080p30. You may also need to adjust your AMF encoder settings, but I'm not familiar enough with it to advise. You may find x264 preferable is your CPU utilization is low.

Hey !
Thank you for your answer

So basically when i use x264, my game lag so much, and my cpu's usage is at 100%
Even if i record in 720p60 or 144p
I don't really know why
Best regards

Ok so X264 is a CPU encoder, and AMD AMF is a GPU encoder.

You're fine using AMD AMF to record, however I would recommend dropping your output (scaled) resolution to 720p at 60fps like Narcogen said. The reason for you dropping frames is because your GPU, which is what AMD AMF encoder is, isn't able to keep up with the recording at the settings you're requesting it to. Also lower your bitrate down to about 10k to 15k when you go down to 720p because 40k will be overkill.
