v1.6.7

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.

Licensing 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)
- Internet remote reviews from anywhere on the world (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

• Docs: Documentation is no longer kept locally and it is instead read from the internet.
• Core: Removed an error when saving a single file without a frame number.
• Core: Fixed a weird but serious bug when saving of OpenEXR images when they had a Data or Display Window set and the format was half float.
• UI/Python: Added support for connecting with Autodesk Flow. The script is barebones. It is up to your studio to improve it. It lives in the python/plug-ins/demo folder. You need to install it manually.
• UI/MacOS: Made the "exec" icon disappear when launching the application.
• Install/MacOS: Added a README.md file with installation instructions for Apple Silicon.
• Python: Made python print() not open the Python Panel. Only errors will open it.
