A plea... Deanna and I have been running this site since 2008 and lately we're seeing a big increase in users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free download site only works if everyone chips in to offset the revenue that ads on other sites bring in. Please donate at the bottom of the page. Every little bit helps. Thank you so much. Sincerely, your Older Geeks: Randy and Deanna Always scroll to the bottom of the page for the main download link. We don't believe in fake/misleading download buttons and tricks. The link is always in the same place. mrv2 v1.4.5 The next generation of mrViewer. Free, professional player and review tool for VFX, animation and computer graphics. mrv2 is the second generation of the popular review tool mrViewer. It is faster, adds python support, networking with path mappings, etc.  Features: Flipbook player Native OpentimelineIO support Video and Audio Playback OpenEXR multipart and multichannel DPX, PNG, JPEG, TIFF, RAW, TGA, PSD, HDR, BMP and Cineon support BSD-3 License Source code on Github (www.github.com/ggarra13/mrv2) OpenColorIO 2 Grease Pencil and other Annotation support Stereo 3D (anaglyph, checkerboard, etc) New User Friendly UI Windows 8.1 and higher, Linux or macOS (Intel) Changes: v1.4.3 10-22-25 Upgraded to OpenColorIO v2.5.0. Upgraded to yaml-cpp v8.0.0. Upgraded to expat R_2_7_2. Upgraded to minizip-ng v4.0.10. Made Voice Over Annotations stop playing or recording when clicking on any other action tool or clicking on voice over annotation tool again. Fixed an incorrect dependency on OpenGL on tlDevice when compiling the Vulkan backend. Added guards on MRV2_NETWORK and TLRENDER_NET for network code. Added support for libaom for encoding AV1 instead of SvtAV1, as it is better supported and portable to aarch64. Removed a line printout debugging from video saving code. Fixed Edit timeline refreshing improperly under Wayland (needs nvidia-drivers-580). Fixed hiding of pixel toolbar on Wayland which had gotten broken. Added getting name of all temporary audio files from voice over annotations. Fixed a crash on A/B Comparison Overlays on the Vulkan backend. Fixed a redraw (trails) on A/B Comparison Overlays on the Vulkan backend when alpha was not solid. Fixed background color/checkers not showing on A/B comparisons on Vulkan backend. Fixed loading of hotkeys. The user's home directory mrv2.keys.prefs takes precedence over the STUDIOPATH one. Made Audio mute's icon turn on (off actually) automatically if volume is too low. Added Mute Hotkey to turn on/off audio ('m' key by default). Added a hotkey to toggle the in/out points together (Shift + 'i' by default). Fixed scrubbing "jumping" when the previous action had been pressing on the timeline bar (like the Stop button). Made color of S (Start) and E (End) range buttons more prominent. Made the color of play buttons match the color of S and E. Fixed drawing annotations not following the cursor accurately. Fixed Text annotations on Vulkan backend which had gotten broken in v1.4.2 due to refactoring of code. Improved performance of draw cursor on Windows by using PRESENTATION_MAILBOX instead of PRESENTATION_FIFO. Fixed decoding of some movies where a frame would be missing with FFmpeg 8.0. Made Save and Reload Session close the original mrv2 and open a new one with the session. Added presentation mode used in Vulkan's viewport when displaying FPS. Fixed resource leak on Vulkan's vmrv2 exit. Improved performance of Vulkan under Wayland to support 4K OpenEXRs at 60FPS properly. Limited usage time of demo to about 9 minutes before exiting the program. Fixed dock panel location when the window was maximized. Made HUD draw an outline on the text to make it more readable. Fixed Linux drawing of timeline and viewport on OpenGL Wayland with buggy NVidia drivers. Vulkan's vmrv2 OpenEXR saving now saves out HDR Primaries as OpenEXR chromaticities. Also, the inverse PQ transform is made to keep the OpenEXR as close to match the HDR video (with the use of OpenColorIO). Added OpenColorIO's ACES 2.0 .ocio files, besides using ocio:// so that artists can inspect and modify the original .ocio configs. Added "Video Primaries Name" to OpenEXR to more easily clasify the chromaticities attribute. Fixed starting up with the Files Panel as a Window under Wayland. Previously, it would cut out the window's height.  This download is for the Windows installer version (very bottom of page).
