obs bitrate for 4k
Hey everyone. Probably a question that everyone already asked a lot. I have a 4k 240 monitor. I want to record gameplay at 4k. But I seem to get choppy video. I have a 4090. What
bitrate is the best for that? Thanks

We'll need more info to be able to help
- Your full system specs
- Screenshots of your OBS encoding and video settings, and possibly your scene layout
- an OBS log file of a time where you were streaming or recording
- Is the choppiness in the recording/stream or also present in the OBS preview?
Also I assume you're streaming to YouTube and not Twitch, correct?
Bitrate doesn’t help framerate to be clear
That’s a separate performance issue
Hi. I have a 14900k with a nvidia 4090. I am recording for YouTube. The chopping is in the recoding. My scene layout is basic. Just camera fx3 and game capture
Please send the requested information if you want help
We still need screenshots of your OBS settings, both the output->recording section and the video section
Hi guys. Here you go
Well you have your canvas set to scale down to 1440p, so that’s not recording 4k at all
The choppiness is probably from the P6 slow preset. Bump that to P2
Turn off two pass and psycho
Still need an OBS log of when it happens
Ok. Thanks. I’ll run it. How do I get a log?
Toolbar at the top of the OBS window,
Help -> Log Files -> Show Log Files
They are named as a timestamp from when you opened OBS, so if you used OBS on September 5th 2024 the log name would be something like 2024-09-05 HH:MM:SS.txt
Find one from a day/time you experienced these issues and upload it heredoes this work?
Looking at that first one, you got a few issues:
1. You have multiple instances of your Fx3 source. Even though they're in different scenes, you could easily reduce your system usage by making the Fx3 in it's own scene, and then nesting that in all of your other scenes that use it. You're already using the
Source Clone plugin for other sources, you can definitely use it for the camera capture
2. You have a source record filter on every single game capture, every Fx3 source, and on your display & browser captures. According to the logs, you're doing NVENC h264 CQP 17 at preset p6 or p7, and have both lookahead and psycho for all of them. These are all very intense options to be running let alone doing it in multiple encodes at the same time. Doing what I mentioned in #1 should reduce the number of sources and similarly reduce load somewhat
For each of these sources you're recording, what is the Stream Mode setting set to?
3. Your Fx3 source has a lot of audio processing issues - if you aren't using the audio from it then consider disabling the audio device for whatever capture method you use for it in the Windows Sound Devices menu or in Device Manager
Also in one of the logs you're recording to FLV container format which will fully ruin a recording if OBS or your system crashes. Use fragmented MOV/MP4 and remux it afterwards
