v1.4.9

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.

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).

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 if you run into issues.

• u$ 25 for a Solo node-locked license for one year.
• u$ 50 for a Standard node-locked standard license for one year.
• u$ 75 for a Edit node-locked license with annotations and editing tools for one year.
• u$ 150 for a Pro node-locked license to own.
• u$ 300 for a Pro+ node-locked license to own (monthly).

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:

- Saving (available from Solo and later)
- Annotations (available from Solo and later)
- Python (available in Standard and later)
- Editing (available in Edit and later)
- Voice Annotations (available in Pro)
- Move license to a new machine (available in Pro monthly)

but has:

• Tone-mapping (OpenGL) and HDR (Vulkan)
• OpenEXR layer switching.
• A donation/license unlocking popup window on start up.

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

ChangeLog

• Improved performance of Vulkan playback of RGB_F16 and RGB_F32 images. Now you can achieve 60 FPS with any card, at the cost of some memory. If your card supports fast compute shaders, you can keep working with RGB_F16 and RGB_F32 images. Just set:

       Preferences->HDR->Prefer RGB->Use RGB.
  

• Fixed Roll and Trim being reversed.

• Added support for .webp images and image sequences. Note that animated .webp pictures are NOT supported.
• Move, Trim and Roll commands on the Edit version of mrv2/vmrv2 are now fully functional. See: https://www.youtube.com/watch?v=K6S-vrwzgz8&list=PLxJ9NNBdNfRmd8AQ41AJYmb7WhN99G5C-&index=22
• Fixed a mutex bug in Vulkan's vmrv2.
• Fixed progress bar on loading a movie file or sequence of frames.
• Fixed a memory leak when dealing with storage images and storage buffers on Vulkan.
• Made OpenUSD compile on Modern Linux distros like Ubuntu 25.10.
• Updated OpenUSD to v25.11 on the OpenGL backend.
• Updated Python to v3.12.12.
• Fixed OpenEXR layer switching on Standard and later licenses.
