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).

Change Log
v1.7.9
- UI: Secondary Window now remembers the screen number and positioning except on Linux Wayland (which does not allow it).

- UI: Added back Playback->Toggle In/Out OTIO clip for .otio and .otioz to make the in and out points for one video clip in the timeline.
- UI: Changing Preferences->Loading->Missing Frame immediately reloads the suquence being shown for updating.
