v1.6.4

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)
- 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

• Updated build to use Svt-AV1 v4.0.1.
• Added Svt-AV1 version to Help->About Window.
• Fixed Preferences->OCIO Display->Display / View selection when there was a single Display.
• Fixed a Linux Wayland Cairo race condition in FLTK when playing back heavy videos.
• Fixed a random crash on Linux Wayland when moving the vmrv2 or mrv2 window from a monitor with scale of 100% to a monitor with a scale of 200%.
• Fixed a minor validation error on vmrv2 when switching to Blit the Viewports.
• UI Improvement: cleaned up Annotations Panel a bit.
• Bug fix: fixed password and suffix entries when opening an URL movie.
• Bug fix: fixed Cancel button when opening an URL movie.
• Python: added session.save_and_reload() to save the session and restart the viewer with the same session. This is useful to propagate changes to the environment variables on Windows.
• Python: added cmd.open_url_movie() for opening url movies with optional user name, password and suffix.
• Building: improved building performance on the cloud.
• Vulkan: fixed showing LA_U8 and similar images.
• Network: fixed synchronizing of two viewers showing up in Edit mode by default.
• Network: Added WebRTC Panel to synchronize two mrv2 or vmrv2 viewers anywhere in the world. Syncing is heavily encrypted and the media does not travel through the web. This feature is disabled by default.
• Core: Removed unused Poco JSON and Poco XML libraries. Makes .exe and similar archive files smaller and improves start up times.
• UI: Fixed a bug where hiding the Secondary Window would mute the volume.
