v1.5.5

mrv2 and vmrv2 are open source professional players and review tools for VFX, animation and computer graphics for Windows, Linux and macOS. You can choose to compile from source or get binaries.

If you are unsure what binary to choose, go to:

https://mrv2.sourceforge.io/downloads/mrv2-download-page.html

mrv2 ships now in two compiled versions:

• mrv2 with OpenGL backend (free and donationware)
• vmrv2 with Vulkan backend (free and donationware)

It also ships for many more architectures, so be careful to download the correct one. It has NOT been tested on Windows aarch64 nor Linux aarch64 (beta testers wanted).

Unlocking Features

For unlocking features, once mrv2 loads, you should go to:

   Help->Unlock Features.

Donationware prices of binary licenses through PayPal:

License works for both mrv2 and vmrv2 (you can have both installed). You need to have an internet connection for the license system.

The donationware version when running without a donation, does not have:

- Annotations (available from Solo and later)
- Python (available in Standard and later)
- Editing (available in Edit and later)
- Voice and Link Annotations (available in Pro)

They do have, however:

- Tone-mapping (OpenGL) and HDR (Vulkan)
- OpenEXR layer switching
- Saving Images and Movies with Audio

Prices might change (go up or down) depending on competition and new features.

ChangeLog

• Added HDR peak detection (working as good as plplay).
• Improved performance of dynamic HDR Data on the Vulkan backend.
• Improved performance of Media Information Panel's Video Tab.
• Added HDR10+ variables to Media Informtion Panel's Video Tab.
• Added Dolby Vision variables to Media Information Panel's Video Tab.
• Added Dolby Vision support on all platforms.
• Added HDR Peak Detection controls to Prefences->HDR Peak Detection.
• Fixed OpenColorIO's 1D Luts on Vulkan backend.
• Fixed ordering of OpenColorIO's textures on the Vulkan backend.
• Improved performance of HDR playback by keeping the state.
• Added sending HDR metadata for proper HDR when using OCIO and not just movies.
• Fixed color picker toolbar always showing solid alpha channel for images with it on the Vulkan backend.
• Fixed color toolbar to support values with 4 digits, like 10000.000 for HDR lookups.
• Removed Vulkan validation errors from NDI's Panel -> NDI Output Stream.
• Sped up NDI Output Stream and hdr utility.
• Made NDI Output Stream not pass metadata when OpenColorIO is enabled.
• Fixed NDI some core dumps.
• Fixed NDI's hdr utility crashes on Windows.
• Improved performance of NDI's hdr utility with changing metadata.
• Added code to handle OpenColorIO properly on Linux with HDR. Still untested as NVidia drivers are still in beta and compositors like Mutter or Kwin are just finishing up their HDR paths.
• Fixed stride in NDI's hdr utility which could cause incorrect displays with odd resolutions.
