v1.4.2

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.

mrv2 ships now in two major compiled versions:

• mrv2 with OpenGL backend (free up to version 1.4.0 - donationware afterwards)

• vmrv2 with Vulkan backend (donationware)

It also ships for many more architectures, so be careful to download the correct one.

Difference between OpenGL and Vulkan

Vulkan is a new open source API, compared to OpenGL that it might get deprecated on some platforms like macOS. It supports true HDR (High Dynamic Range), it is about 20% to 50% faster than the OpenGL version (on Windows, macOS M1+ and it is the same speed for Linux's GNOME 48 and later) but it does not support OpenUSD.

OpenGL's main benefit at this point is that it supports OpenUSD and works better on old CPUs (macOS Intel and older X11 backend).

Prices for binaries

Donationware prices of binary licenses through PayPal:

I use the email information to contact you privately. I don't sell your information, as I don't have access to it, except for your email, which I use to contact you.

• u$ 50 for a node-lock license for one year.

• u$ 150 for a node-lock license to own.

• The prices are cumulative. If you donate, say u$10 in 5 months, you can access the node-lock license for one year.

License works for both mrv2 and vmrv2 (you can have both installed). You need to have an internet connection for the license system.

ChangeLog

• Added untested Linux aarch64 builds, without NDI.
• Added untested Windows aarch64 builds, without NDI or SVT-AV1 encoder.
• Upgraded OpenJPH to v0.24.1 from OpenEXR's internal version.
• Fixed incorrect use of FLTK_USE_WAYLAND when not in Linux.
• Fixed incorrect use of FLTK_USE_X11 when not in Linux.
• Made volume slider automatically unmute the audio if it was muted.
• Added "File/Open/New Program Instance" to pop up a new mrv2.
• Made Erase tool support Alt + Drag to clear a rectangular area quickly.
• Fixed subwindow panels flickering/wobbling under Wayland and X11. Tested under:
  • Wayland Ubuntu GNOME Shell 48.0 (older GNOMEs may still wobble)
• Fixed lookup of machine's UUID for licensing on Windows aarch64 builds.
• Created a web server for node-lock licenses so that licenses are, in principle, not vulnerable to cracks.
• Added support for network licenses for a facility.
