v1.6.0

mrv2 and vmrv2 are open source professional players and review tools for VFX, animation and computer graphics for Windows, Linux and macOS. You can 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)

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.

Change Log

• UI improvement: Improved readability of the Media Information Panel.
• UI improvement: When using the free version of mrv2/vmrv2, the menu functions supported only on unlocked versions are shown as ghosted instead of just missing. That way users can tell what vmrv2 / mrv2 FULLY supports.
• UI improvement: The Files panel allows changing the sort order of the elements (Loaded, File Name, Directory and User name). Just use the RMB on a clip and select Order/File sName.
• UI improvement: The vectorscope has been rewritten.
• Added support for sequences with a suffix like render_0001_suffix.exr in file requester, drag and drop and command-line.
• Major refactoring of code.
• Fixed a Vulkan hang (VK_ERROR_DEVICE_LOST) when creating thumbnails in the Edit timeline window. It would happen with .otio timelines.
• Fixed a hang and crash on program exit after editing a clip with the Trim tool.
• Added File->Open->URL Movie to open a movie with an URL to allow direct streaming of movies into vmrv2 from an https:// or http:// site. By default, a sample link is provided for evaluation.
• Vectorscope no longer clamps values.
• Fixed Vectorscope layout and improved its performance.
• Added type to vectorscope to switch from ITU 709 and ITU 601.
• Fixed getting out of temporary selection mode by using scrubbing when it was not visible.
• Fixed color::rgb::to_ITU601 conversion to be done in float.
• Fixed coefficients of color::rgb::to_ITU709.
• Fixed mrvColor's L_F32, LA_F32 and L_U8 conversions.
• Fixed vectorscope on Vulkan and OpenGL as the values were not right.
• Updated to FFmpeg 8.1.
• Updated to NASM 3.02rc3.
