v1.4.4

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 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 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

• Made default Read Ahead be 4 seconds instead of 2.
• Frame/Seconds/Timecode widgets now handle focus by clicking on them instead of just entering them.
• Made Vulkan save out images and sequences with full color corrections (HDR + OCIO) if those are active.
• Added Link Annotations. Title is shown as a tooltip when moving the mouse pointer near the Link drawing.
• Added Link Annotations to Session saving.
• Added path mapping to Link Annotations.
• Fixed a Linux Wayland warning about Always On Top when dragging a File item under Gnome.
• Made popup menus on viewport use a bigger font for better readability.
• Made docking faster when subwindow is dragged to it (open/close dock).
• Fixed Automatic color buffer type selected when YUV_420P_U12/16 and similar depth movies are loaded in both OpenGL and Vulkan.
• Fixed saving in Vulkan all RGBA image types supported by vmrv2.
• Improved precision of PNGs by saving RGB_U16 or RGBA_U16 when possible.
• Cleaned up saving movie/image code in the Vulkan backend.
• Improved performance of image saving code in the Vulkan backend.
• Improved performance of panel subwindows dragging on Wayland.
• Fixed saving elapsed time being not being in milliseconds in the progress report bar.
• Fixed showing Original (O) pixel values on the Vulkan backend as image was flipped in Y.
• Made thumbnail generation on both Vulkan and OpenGL backends faster.
• When saving out a temporary session file (temp.mrv2s or lang.mrv2s), the current session file is no longer updated to it.
• Fixed -p Stop command-line flag stopping after playback was started when AutoPlayback was on in the Preferences.
• Fixed thumbnail generation on Vulkan making the playback stutter.
• Improved the performance of video decoding.
• Improved the performance of sequence decoding (all formats).
• Fixed Linux directory selection in file requester, not allowing selection when travel single drawers was on.
