v1.6.9

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 (v)mrv2 loads, you should go to:

   Help->Unlock Features.

Licensing 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

Donation amounts might change (go up or down) depending on competition and new features.

• Install: (Linux) Fixed dpkg -i reinstall of the same version on Debian/Ubuntu systems.

• UI: Added tablet eraser support when drawing free-hand, allowing you to toggle between drawing and erasing mid point.

• UI: Fixed one really nasty crash in the color picker due to some variables being derived from the wrong class.
• UI: Fixed HEX pulldown of color picker which was using decimals instead.
• UI: (Linux) Fixed Kwin/Plasma's windows decorations. Now vmrv2 on that window manager shows with nice decorations.
• UI: (Linux) Added Tablet support to libdecor's cairo and GTK3 plugins, without modifying its sources, to allow moving, minimizing, maximizing and closing the window.
• UI: Added Tablet support for the panels to allow them to be moved and docked with the pen.
• UI: Allowed resizable bar to the right of viewport to be resized with the tablet.
• UI: Made showing of tooltips optional in Window->Preferences.
• UI: Made floating panels respond properly to tablet events.
• UI: Fixed two Edit buttons which could potentially not show up on ARM64.

• UI: All shapes now respond properly to tablet/pen pressure.

• Core: Updated PNG version to v1.6.58.

• Core: (Linux) Fixed crashes when using FLTK_BACKEND=x11 on Linux's Vulkan build.

• Build: Conditionally allowed building with less features.

• Build: WIP. Added -D USE_SYSTEM_LIBS=ON for faster building using system libraries when possible instead of building from source, even if you are not getting cutting edge performance. However this should make it simpler for Unix distros to bundle vmrv2/mrv2 with apt, dnf, snap or flatpack.
