OBS screen recording not capturing at the set bitrate

[techmot]

Hi, does anyone why my OBS may be outputting the wrong video and audio bitrate?. Last week I was trying to capture better screen recordings of a video and wanted to reduce the stuttering on the captured file. I think someone on here advised me to set the encoder to "slowest possible" in the Encoder Preset tab (though IMO there wasn't much difference). I've been setting the video bitrate in OBS at 9000kbps, and audio at 320. But I've noticed today when I was capturing again that despite the video and audio bitrate being set at that, that I'm now getting a video bitrate of around 4000kbps and audio 160kbps. I changed Encoder Preset setting back to what it was but it was still the same. As far as I can remember I havn't changed any other settings to reduce the bitrates.

I don't understand what you were exactly trying to do. Capture a video already encoded ? If you intended to use OBS as ffmpeg.. you didn't understand the purpose of OBS at all.

If you are using OBS properly.. well, again.. it's not FFMPEG. You can put any values in the settings, but the effective results depend on the codec you choose, the capability of your hardware and (if you're streaming) your internet connection too.

No I'm trying to screen record from a website. As I said, up until I changed the "Encoder Preset" settings last time I was screen recording I was getting the bitrate that I had set it to, which was9000kbps, but now for some reason, despite the video and audio bitrate being set at 9000 and 320 I'm getting a output of around 4000kbps for video and 160kbps for audio where I wasn't before.

You're on the Streaming Settings there. Put the Output mode on Advanced and then go down to the Recording section. You'll find the 4 presets are replaced by the actual bitrate you can type into the now-visible "Encoder" Settings section.

I haven't changed anything in the recording settings, so it should've been still set to 9000kbps for video. It says Video Encoder is set to "stream encoder", though I'm not sure if that's what it was set to originally. When I drop down and select "x264" it gives the video at 2500kbps. In the "audio" tab the bitrate is still set to 320kbps, but I was getting an audio bitrate output of only 160.

That's exactly the wrong device. You want to use fast settings, not slow settings, to reduce the possibility of dropping frames, and hence, jerky video. You also want to avoid audio compression while capturing as most audio encoders are single threaded and that can also create a bottleneck when capturing.

*advice?

@Techmote, set your "Output" up like this:

On the Audio tab, set 192 in Track 1.

You'll get your chosen bitrate for video and audio. Remember Constant Bitrate is not very efficient, especially when there's little movement. VBR is better.

Notes: If you get stuttering, adjust the CPU Useage (as per Jagabo's note: "faster" is easier on your system) or drop the bitrate.
