Bug Report OBS only recording at low bitrate

[The Etcetera Kid]

I've been recording my shows at 1080p 30fps using FLV (X264) with CRF 18. File size is around 3.5gb/hour.

Earlier this week I tried switching to using MKV so that I could record multiple audio channels. I noticed that the recorded file size dropped down to around 1gb/hour.

I tried switching back to FLV and I'm still getting 1gb/hour despite my settings being seemingly the same as they were originally, meaning OBS is recording now at a much lower bitrate than it was previously.

I've attached my current recording settings as well as the most recent log file.

Any ideas?

Thanks for your help!

Try this.

Thanks Harold, I used that link what I first tried setting up multitrack audio recording.

The issue here is that even with single track audio recording, FLV recording, which used to record at a rate of 3gb/hour, is now recording at 1gb/hour. So I either made a mistake somewhere or there is a bug in OBS.

I've been using the same FLV setting for many shows, so this is a recent issue.

Is the quality changing when the bitrate does?
Are you sure you're using the EXACT SAME encoder settings?
