ChangeLog

• Upgraded to OpenColorIO v2.5.0.
• Upgraded to yaml-cpp v8.0.0.
• Upgraded to expat R_2_7_2.
• Upgraded to minizip-ng v4.0.10.
• Made Voice Over Annotations stop playing or recording when clicking on any other action tool or clicking on voice over annotation tool again.
• Fixed an incorrect dependency on OpenGL on tlDevice when compiling the Vulkan backend.
• Added guards on MRV2_NETWORK and TLRENDER_NET for network code.
• Added support for libaom for encoding AV1 instead of SvtAV1, as it is better supported and portable to aarch64.
• Removed a line printout debugging from video saving code.
• Fixed Edit timeline refreshing improperly under Wayland (needs nvidia-drivers-580).
• Fixed hiding of pixel toolbar on Wayland which had gotten broken.
• Added getting name of all temporary audio files from voice over annotations.
• Fixed a crash on A/B Comparison Overlays on the Vulkan backend.
• Fixed a redraw (trails) on A/B Comparison Overlays on the Vulkan backend when alpha was not solid.
• Fixed background color/checkers not showing on A/B comparisons on Vulkan backend.
• Fixed loading of hotkeys. The user's home directory mrv2.keys.prefs takes precedence over the STUDIOPATH one.
• Made Audio mute's icon turn on (off actually) automatically if volume is too low.
• Added Mute Hotkey to turn on/off audio ('m' key by default).
• Added a hotkey to toggle the in/out points together (Shift + 'i' by default).
• Fixed scrubbing "jumping" when the previous action had been pressing on the timeline bar (like the Stop button).
• Made color of S (Start) and E (End) range buttons more prominent.
• Made the color of play buttons match the color of S and E.
• Fixed drawing annotations not following the cursor accurately.
• Fixed Text annotations on Vulkan backend which had gotten broken in v1.4.2 due to refactoring of code.
• Improved performance of draw cursor on Windows by using PRESENTATION_MAILBOX instead of PRESENTATION_FIFO.
• Fixed decoding of some movies where a frame would be missing with FFmpeg 8.0.
• Made Save and Reload Session close the original mrv2 and open a new one with the session.
• Added presentation mode used in Vulkan's viewport when displaying FPS.
• Fixed resource leak on Vulkan's vmrv2 exit.
• Improved performance of Vulkan under Wayland to support 4K OpenEXRs at 60FPS properly.

Notes on installation

• On macOS you install it by opening the .dmg file, and dragging the vmrv2 icon to the Applications directory. If there's already a vmrv2 version, we recommend you overwrite it. The macOS application is currently not notarized, so when you launch it you will not be able to run it as macOS will warn you that the file is not secure as it was downloaded from internet. To avoid that, you need to open the Apple Logo->Settings->Privacy and Security and go to Security and allow "Opening Anyway". Alternatively, you can do it from the Terminal, by:

  sudo xattr -rd com.apple.quarantine /Applications/vmrv2.app/

• Windows and Chrome, like macOS, also protect you from installing files from the Internet. When you first download it with Chrome it may warn you that it is not an usual archive to be downloaded. Make sure to click on the right up arrow menu to Save it anyway. You cannot open the .exe from Chrome directly. You will need to open Windows Explorer and go to the Downloads directory. You should then run it from there. Then Windows will popup a Blue box telling you Windows SmartScreen prevented the start of an unknown application and that you can place your PC at risk. Click on the More Information text and a Button that says Run anyway or similar should appear. Click on it and follow the standard instructions to any Windows installer. One note about the Windows install. When asked if you want to add vmrv2 to your PATH, it is recommended to answer No to it, as it avoids DLLs conflicts with other applications that use common libraries like FFmpeg or OpenUSD.

• On Linux, in order to install the .rpm or .deb packages requires your user to have sudo permissions.

On Debian (Ubuntu, etc) systems, you would install with:

  sudo dpkg -i vmrv2-vulkan-Linux-amd64.deb

On Fedora, you would install it with:

  sudo rpm -i vmrv2-vulkan-Linux-amd64.rpm

Once you install it, you can run mrv2 by just typing vmrv2 in the shell, as a symlink to the executable is placed in /usr/bin. The installers will also associate file extensions and install an icon for easy starting up in the Desktop icon of the user that installed it. For running vmrv2 with the icon, you need to select it and use the right mouse button to open the menu and choose Allow Launch.

If you lack sudo permissions in your organization, you should download the .tar.gz file and you can uncompress it with:

  tar -xf vmrv2-vulkan-Linux-amd64.tar.gz

That will create a folder in the directory you uncompress it from. You can then run vmrv2 by using the mrv2.sh shell script in the bin/ subdirectory.

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 GNOME48 compositors and an HDR monitor.

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

The preferred NVidia driver tested for best performance is nvidia-driver-570 (default on Ubuntu 25.04 with GNOME48).

Notes about Vulkan on macOS Intel

• Only up to Vulkan 1.3 is currently supported.
• HDR on macOS needs a MacBook Pro. MacBook Pro Intel will give you up to 1000 Nits of HDR depending on model.
• MacBook Pro Silicon should work with any M1 device up to HDR+.
