Anyone else notice that the HEVC encoder doesn't seem to work in 0.12.0a106? I know it probably doesn't support HDR colorspaces yet, however it doesn't even seem to initialize when doing SDR recording in OBS Studio 28. I found that if I configure OBS Studio's FFMPEG encoder manually for NVENC HEVC and that it works fine, and I can record in HDR (with higher quality/better efficiency at lower bitrates than OBS Studio's own NVENC HEVC encoder), however OBS Studio still doesn't allow you to live stream with FFMPEG so if I want to live stream in OBS Studio 28 then I'm stuck with their awful NVENC encoders. |

That log also shows you configuring OBS Studio for HDR: |

You're looking at the wrong section of the log. It was configured for an sRGB color space (both in OBS Studio advanced settings and the game capture in the scene) with a limited color range when recording started. I switched profiles back to "Local Recording Only (HDR)" before closing OBS Studio, so it was configured for HDR when it was launched, however I changed it to SDR before attempting recording with StreamFX's HEVC FFmpeg encoder. Here are screenshots of the OBS Studio settings and game capture settings that were used when that log was saved: |

I'm well aware of what to look at in a log file. Neither of the provided log files is configured for Rec. 709, only Rec. 2100 (PQ)/Full is configured. |

Does that mean OBS Studio 28 is not changing color spaces and color ranges when switching profiles? |

Well, according to your provided log files, neither of the instances is in Rec 709. It appears that is the case then. |

⚠ Preview Release not for Production! ⚠
This release is meant for testing in isolated conditions and early adopters only, and should never be used in production. If you use one of these releases, all promises of support, warranty, functionality, and similar are immediately void and if things break you are on your own. The latest production ready release can be found here.
Please read the Installation Guide and System Requirements!
The installation of StreamFX requires that you follow certain instructions, as well as fulfill a minimum hardware and software requirement. Please ensure that you have read and verified both before asking for help, as many issues can be fixed by reading both of them in their entirety.

Overview of Changes
New Release process: Alpha -> Beta -> Candidate -> Release!
The old two stage system didn't work out quite as I'd have hoped: It didn't communicate the dangers of Testing well, and did not differentiate between different stability levels. To solve this I've adopted a new release process now available in StreamFX, which follows the usual development cycle of Software itself: Alpha -> Beta -> Candidate -> Release. The further right you go in that graph, the more stable software is supposed to be, at the cost of new features and changes. The further left you go, the more up-to-date things will be, but you sacrifice stability and safety.
Avid DNxHR Encoder (via FFmpeg) by @IceStormNG
A new contender for the visually lossless intermediate codec arrives: Avid DNxHR! Thanks to work done by @IceStormNG, it is now possible to use this encoder without configuration trickery and directly configure it with a proper user interface. As this encoder is based on the real codec specification, it may perform better than the Apple ProRes encoder while being way more compatible with video editing software.
ARM64 Support on MacOS
As OBS Studio 28.0 and beyond support ARM64 and x86-64 now, StreamFX now also supports this architecture natively. Note that you may need at least MacOS 11.0 for the ARM64 binaries to load correctly.
Deprecation of the AMD AMF (via FFmpeg) encoders
With OBS Studio 28.0 the old obs-amd-encoder project is finally laid to rest and a new AMD AMF integration is provided. This AMD AMF integration is technically and functionally superior to both the old obs-amd-encoder and FFmpegs AMD AMF integration. All users are urged to migrate as soon as possible, as no guarantees are made for how long this deprecated encoder will remain. Additionally, users on Linux should put their focus on the open Pull Requests for Linux support (1, 2.
Deprecation of the AV1 (via AOM) Encoder
With OBS Studio 27.2.4, the SVT-AV1 and AOM-AV1 encoders were integrated into OBS Studio directly. This integration is functionally identical, and as such replaces the StreamFX provided AOM-AV1 encoder. All users are urged to migrate as soon as possible, as no guaratees are made for how long this deprecated encoder will remain.
Shader Texture Inputs no longer corrupt Scene Collections
For quite some time, Shader Texture Inputs were haunted by ghosts from the past, also known as work-arounds and deprecated code. This resulted in Shader Texture Inputs keeping stale references around and requiring an OBS Studio restart to actually update. Several code modernization cycles later, this is now fixed and Shader Texture Inputs immediately update as expected - while also no longer keeping stale references around, so your Scene Collections are safe again.
