The Vulkan releases at:

https://sourceforge.net/projects/mrv2/files/beta/vulkan

directory are versions for you to evaluate mrv2 or vmrv2 before a donation and report bugs or performance issues. Currently, when run as demo these versions don't have:

   - Full Annotations and Color Areas
   - Editing
   - NDI support
   - Performance as good as the release builds

They do have, however:

   - Tone-mapping (OpenGL) and HDR (Vulkan)
   - OpenEXR layer switching
   - Saving OpenEXRs and Movies with Audio
   - A Menu Option (Help->Unlock Features) to unlock features
     based on donations.

ChangeLog

• UI: Allow artists using the Demo version of the players to see the timeline in full by dragging the separator without requesting an Edit license.
• UI: Allow timelines to be compared.
• UI: Reordered Window->Preferences into a more logical order, without changing names so as to remain backwards compatible.
• UI: Improved the readability of the HUD by using a transparent rectangle instead of text shadow. This also improves performance a tad on the Vulkan backend.

• UI: Updated translations.

• UI/Core: Allow scrubbing (with audio on the first clip) while in Compare Mode.

• UI/Core: Improved accuracy of FPS and dropped frames counters, supporting seeks and reverse playback properly.

• UI/Core: Improved reverse playback caching.

• Vulkan/Core: Improved playback performance even more.

• Core: Improved pre-caching of movies that could make it drop several frames at the start of playback.

Fixes

• UI: OTIO in Timeline Viewport was using OCIO on .otio files even when Preferences->OCIO Not on Videos was set on the Vulkan backend.
• UI: Vulkan Wipe comparison would render green if there was no video at the current time.
• UI: Some wrong translations and items in Window->Preferences.
• Core: Made changing languages release a floating license previous to restarting.
• Core: Fixed a potential compilation error on DirEntry's size.
• Core: Fixed .github/workflows to work on new Github macOS M1+ runners.

Notes about Vulkan on Windows

In order to get HDR, you currently need to have Windows 10+ (11 is ideal) and an HDR monitor.

Notes about Vulkan on NVidia Linux

In order to get HDR, you currently need to have the KWin6 or GNOME50+ (Ubuntu 26.04 LTS) compositors and an HDR monitor.

It will likely work with any NVidia RTX 3080+, but it will require you to choose and test your hardware carefully.

The preferred NVidia driver tested for best performance is nvidia-driver-595+.

Notes about Vulkan on macOS Intel

• The application is now notarized and code-signed.
• Only up to Vulkan 1.3 is currently supported.
• HDR on macOS needs a MacBook Pro. MacBook Pro Intel will give you up to 200 Nits of HDR.

Notes about vmrv2/mrv2 on macOS Silicon

• The application is now notarized and code-signed.
• For MacOS Intel, a MacBook Pro is recommended.
• MacBook Pro Silicon should work with any M1+.
