v1.5.6

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

• Fixed EDID connector to support Asahi Linux eDP-1 in mrvMonitor_linux.cpp.
• Fixed NDI's hdr utility hanging on Debug builds on Linux.
• Made NDI's hdr utility thread safe, as it was potentially stomping on FLTK.
• Fixed NDI Input streaming inside mrv2 / vmrv2 to not bring up the progress bar.
• Fixed FLTK reporsitory to make Vulkan backend on MacOS match the scores of the Linux counterpart to select: VK_COLOR_SPACE_HDR10_ST2084_EXT for proper HDR, instead of DISPLAY_P3.
• Made common sRGB formats tonemap automatically under Vulkan. Linear or floating point images need to use the proper OpenColorIO transforms.
• Added isOTIO to the list of sRGB formats to tonemap automatically under Vulkan.
• Added NITS to one of the Pixel Color Values you can display in the Pixel Bar besides Full and Original.
• Added Linear to one of the Pixel Color Values you can display in the Pixel Bar.
• Fixed Channel switching (ie. Red, Green, Blue, Luma) on OpenEXRs which had gotten broken on Linux.
• Fixed Vectorscope placing colors in the wrong direction.
• Improved Vectorscope by allowing it to be resizable.
• Made current time in timeline reposition itself if it would clip outside the window.
