v1.8.3
mrv2 and vmrv2 are open source professional players and review tools for VFX, animation and computer graphics for Windows, Linux and macOS. You can 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.
If you're unsure which download you need, use:
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:

ChangeLog
- UI: Added options to Preferences->Edit to hide or show effects, waveforms and thumbnails.
-
UI/Core: Fixed moving the primary display window between an HDR and SDR monitor on Windows, which could sometimes not update the HDR Display properly.
-
UI/Edit: Edit->Time->Slice now supports selected items to only slice on the selection.
-
UI/Edit: Edit->Associated Clips is now more reliable when moving a video and audio clip in the timeline. It will move ALL video and audio clips with similar start/end points.
-
UI/Thumbnails: They now support HDR and OpenColorIO in both Panels and the Timeline Viewport, on both backends.
-
Core/MacOS: More support for hardware decoding of more codecs, HDR, seeking forwards and backwards and memory I/O on MacBooks Pro Intel and M1+ with a python unit test for quality checking. PR [#540]. Courtesy of @CatPetrova.
-
Core: Missing frames from a, usually, rendered sequence are now polled on disk and loaded on demand when they are found, taking very little resources.
Fixes
-
UI: Fixed tooltips for AutoICS now showing with color space was selected and why.
-
Edit/Core: Moving a clip with annotations in an .otio timeline with a global_start_time() > 0 would not offset the annotation correctly.
-
UI/Thumbnails: Refreshing the thumbnails would only refresh the first thumbnail in the Panels.
-
UI/Core: Fixed a potential Linux Wayland crash when saving a clip and stopping it mid-way with the Esc hotkey.
