WARNING: If you are using Groups in your Scene Collection, there is a known issue that may result in their size/position being shifted when using Beta1. We are working on a fix, which can be tracked here. If your scenes are affected, please note that a backup is created before migration to the new relative coordinates system, and can be found in your OBS settings directory, under the file <name>.json.v1, where <name> is your scene collection name. This is fixed as of Beta2

Disclaimer: This is a test build, not a full release. Please ensure you make a backup of your scene collection and profile. This build may contain bugs or broken functionality. For production usage, we still recommend using the latest stable build of OBS. If you are willing to test this build, let us know if you run into any issues.

OBS Studio 31.0 Beta3 is now available for testing! This release comes with new NVIDA Blur and Background Blur filters, easier scrolling of the preview when zoomed, improved YouTube Chat support, a long-awaited update to the Browser Source (including custom docks and service integrations!), a rewritten NVENC encoder for better performance, and many backend changes and optimizations for upcoming features in newer versions.

To enable the beta version, either download from the GitHub link below, or on Windows/macOS go to Settings -> General and change the Update Channel to Betas / Release Candidates

Hello! Tried this update, and a lot of my sources are now resized completely wrong so I've had to redo a bunch of my scenes sadly. :(

Just to confirm, were you using Groups for the sources that had their sizes changed? Please provide a log file if possible.

EDIT: As a note, the original scene should be saved as a backup before the migration as a ".json.v1" file in the OBS settings directory. Once we fix the issue with Groups, it can be re-imported and should be still fine.

Exactly, I was just messing about with it more and it seemed to be related to groups. Thanks for the help. :)

That log does not appear to contain an attempt to start output. Reproduce the error message, and then do Help -> Log Files -> Upload Current Log, grab the link and post here.

No worries! The issue is that you need to set bframes to at least 4 for that tune to work properly. There was supposed to be a guard/fallback that set it automatically, but it was just an oversight. We'll get it fixed by final release.

Has/can the issue with RNN Noise cancellation be fixed in this version. I run 30.2.3 and cpu usage by goes up 15-20% when the mic is physically muted. All drivers are up to date. I have restarted obs in safe mode and I am still getting issue. I have added a test scene collection with only the mic added (with RNN noise suppression filter) and it still occurs so this issue HAS to be coming from the base OS or base OBS build and since it was in safe mode, it’s not a plugin issue. I can use Speex without any spike in render times, both with mic on mute and unmute but the moment I use RNN and mute mic render goes up. When I unmute it’s back to normal. It is undetectable in a log because i am using the physical mute button on the mic.

So yeah, I have a lot of groups and scenes and the locations go haywire to the point that I simply rolled back, and used the backup scene to repair. Is the new coordinate system coming whether we like it or not, and are our groups destined to be jumbled up in the near future? Because if so I will simply bite the bullet and start working the show over to accommodate. If not, I will simply wait for the mitigations to be in place before upgrading when the release comes.

Thanks in advance, looks like a great update otherwise!

Does that include browser plugins? Like adblock for example?

For this version, no. If we want to support browser plugins in the future (which adds additional complexity and security complications) we currently have a long road ahead to prepare for such an eventuality.

To clarify the above, we do not have any current or long term plans to support extensions in browser source/panels.

OBS crashes immediately upon opening after updating to this version. Is there an easy way to roll back without losing my profiles/scenes?

I have the exact same problem - OBS crashes at startup without any screen loaded and it reports it crashed - i figured out it has something to do with commandline arguments - when i open OBS with a shortcut that does not have commandline arguments it loads my last used webcam.

As with any beta, we recommend making backups of all your scene collections and profiles. As for this crash, it appears to be related to the NVIDIA broadcast effects filters, make sure your GPU drivers are fully up to date, and you're on the latest version of the NVIDIA Broadcast SDKs.

This is likely unrelated to the beta, and not something that has been reported. I recommend going through our normal support channels for assistance looking in to this.

The issue with groups having their transform improperly assigned is fixed in Beta 2.

Please provide the crash log, as this might not be related, as well as what the exact launch arguments you're using are, otherwise we cannot investigate.
