OBS Studio 32.2 landed yesterday with three changes that affect real streaming setups. The most technically interesting is a native SDR-to-HDR composition filter — something streamers have needed for years and previously had to fake with workarounds. It also adds dynamic bitrate support to multitrack video, which is the one thing that was missing for streamers running Twitch’s Enhanced Broadcasting. And if you’re on a Mac with an M-series chip, there’s a forced migration baked into this update that will silently break your third-party plugins if you’re not prepared for it.
The SDR-to-HDR Filter Fixes a Broken Default
Until now, OBS handled SDR content inside an HDR scene by defaulting to sRGB — which looked wrong. The issue is that Rec. 2100, the HDR color space OBS targets for HDR output, is calibrated for dim viewing environments. sRGB is not. The result was inflated blacks and washed-out SDR overlays sitting awkwardly on top of HDR video.
The new filter composes SDR sources into HDR by applying a power-of-2.4 gamma curve that simulates Rec. 709 viewing conditions. That matches the assumed viewing environment between SDR and HDR and gives you consistent-looking composites without external tone-mapping tools.
Who should care: if you stream to YouTube or Twitch in HDR and mix in SDR sources — browser alerts, overlays, secondary cameras — this is the fix you’ve been waiting for. Apply it as a filter on your SDR sources inside an HDR scene.
Dynamic Bitrate Finally Comes to Multitrack Video
Multitrack video — what Twitch calls Enhanced Broadcasting — has been in OBS since version 30.2. The feature sends multiple video tracks simultaneously at different resolutions, letting platforms serve the right quality to each viewer without relying on platform-side transcoding. For most streamers, it’s the only way to give 480p access to viewers with slow connections while still pushing 1080p60 to everyone else.
The problem: when your network hiccuped during a multitrack session, OBS had no automatic recovery. You’d drop frames and either intervene manually or restart the stream. Dynamic bitrate already existed for single-track streams but was absent from multitrack — which is exactly backwards given that multitrack is far more bandwidth-sensitive.
OBS 32.2 closes that gap. Dynamic bitrate now covers multitrack video output, automatically reducing bitrate when conditions deteriorate and recovering when they stabilize. It’s a small entry in the changelog but a meaningful operational improvement for anyone using Enhanced Broadcasting.
Mac Users: Check Your Plugins Before Updating
This is the part of OBS 32.2 that will catch people off guard. If you’re running an Intel build of OBS on an Apple Silicon Mac — something that worked fine under Rosetta 2 — version 32.2 will automatically migrate you to the native ARM build. No prompt, no option to decline.
The performance is better. Native Apple Silicon execution beats Rosetta translation by a meaningful margin. But third-party plugins compiled for Intel will stop loading immediately after the migration. They won’t crash OBS — they just won’t appear. If your setup depends on a niche plugin (a capture card driver, an audio routing plugin, a custom overlay tool), you need to confirm that an Apple Silicon (ARM64) build exists before you update.
If it doesn’t exist yet, stay on OBS 32.1 until your plugin developer ships an ARM64 build.
New Add Source Dialog
The dropdown menu for adding sources is replaced with a dedicated dialog window. The new dialog supports search and filtering, and plugins can now provide custom icons for their source types. New users will find it significantly easier to navigate. Experienced users will barely notice beyond the first session.
Linux: PipeWire and VAAPI AV1 Fixed
OBS 32.2 resolves a PipeWire capture failure that affected NVIDIA GPU users on Wayland — a historically broken combination. It also restores VAAPI AV1 encoding for WHIP streams, meaning hardware-accelerated AV1 streaming works again on Linux for streamers using WebRTC-based outputs. NVENC bitrate selection in CQVBR mode is also corrected. If you’ve been stuck on an older OBS version specifically because of these Linux issues, 32.2 is the update to make.
How to Update
OBS Studio 32.2.0 is available now at obsproject.com for Windows, macOS, and Linux. Full release notes are on GitHub. The in-app updater on Windows will offer it automatically. macOS and Linux users can download from the official site or via their package manager.
If you’re on macOS with third-party plugins: audit your list first, confirm ARM64 versions exist, then update. Everyone else can update immediately — there’s nothing in 32.2 that warrants waiting.
