v1.8.0

mrv2 and vmrv2 are open source professional players and review tools for VFX, animation and computer graphics for Windows, Linux and macOS. You can build them from source or download prebuilt binaries.

Binaries are available for multiple operating systems and CPU architectures. Be sure to download the correct one for your system, and check all release assets—GitHub often hides part of the list.

Guided Downloads

Two versions are available:

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

It has NOT been tested on Windows aarch64 (beta testers wanted).

Unlocking Features

To unlock donationware features, open:

Help->Unlock Features.

The same license works for both mrv2 and vmrv2, so you can have both installed. An internet connection is required for license activation.

Without a donation license, the following features are unavailable:

Full Annotations and Color Area Selection (Solo+)
Python (Standard+)
Editing (Edit+)
Voice and Link Annotations (Pro)
Unlimited WebRTC Remote Reviews (Pro)

The free version still includes:

Tone-mapping (OpenGL) and HDR (Vulkan)
OpenEXR layer switching
Saving Images and Movies with Audio
Limited WebRTC Remote Reviews (2 artists for 30 minutes)

Change Log

• UI: Movie files and sequences with associated audio also allow turning off any of the two tracks.
• UI: Built-in File Requester (used mainly on Linux) no longer shows the patterns in a floating window.
• UI: Added tooltips in the status bar for each menu entry.
• UI/Core: Annotations are now drawn much faster, as they don't need three render engines.

• UI/Compare has been moved to Image/Compare Mode. You can now also easily select what to compare from the RMBB menus.

• Command-Line: Now -systemInfo will list all libraries used in the players.

• Command-Line: Now -systemInfo will now show up the start up message.

• Command-Line: Now -systemInfo properly displays the graphics card information on the OpenGL backend.

• Core/Command-Line: Opening many files at once or a directory no longer reads every one of them immediately.

• Core: The Vulkan backend now starts much faster and uses less memory.

Fixes

• UI: Built-in File Requester could crash the application when switching extension patterns.

• UI: Area selection had a bug which prevented it from marking an area bigger than one pixel.

• Command-Line: Displaying -systemInfo does not hang the Vulkan backend.

• Edit: Made all Edit functions work properly.

• Core: Switching back to Preferences->Loading->Missing Frames->Error would not trigger a reload of the file.

• Core: Adding a text annotation no longer crashes vmrv2. This was a regressionfrom v1.7.8.
