v1.6.3

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 two new Compare Modes (Add and Multiply). Multiply can be useful to check ambient occlusion passes.
• Added Image->Compare->Toggle A and B to easily switch the order of comparisons.
• Fixed missing suffixes in Image->Go To.
• Fixed missing suffixes in PDF's images creation titles.
• Fixed the Non-Native File Requester on Windows not allowing to show the drives.
• Fixed building on the cloud with potentially only 1 CPU.
• Fixed OCIO Looks always overriding potential Looks attached to a custom Display transform.
• Fixed Path.cpp and File.cpp code for UTF-8 under C++20 (wrong use of u8strings)
• MAJOR BUG FIX: Fixed Vulkan Text Annotations which had gotten broken due to a requested change in path handling. Now it works correctly, including emojis.
• Fixed .webp image sequences not working when they had a suffix.
• Improved and fixed minor bugs in the postinst.in and postrm.in scripts used on Linux's DEB and RPM packages.
• UI improvement: On Linux Vulkan Wayland builds, fixed the blurriness of the timeline.

• Moved usdviewer utility into its own repository at:

  • https://github.com/ggarra13/usdviewer

It was making the Vulkan vmrv2 slower to load.
