mrViewer is a small, lightweight utility that can open images and play video files. It supports .BMP, .JPG, .PNG, .PSD, .MAP, .DPX, .MP4, .MPG, .MOV, .AVI, .DIVX, and .WMV file formats.
With mrViewer you can add files by simply dragging and dropping them into the main panel or you can use the browse button to locate your media. It comes with a couple of tools that allow you to specify the frame rate, play or stop the current video selection, skip to the start or end position of a clip, adjust the volume, alter the RGB value, and adjust the levels for gamma and exposure.
Key Features include:
- Flipbook player.
- HDRI viewer.
- Multichannel support in OpenEXR, .PSD, .MIFF and .TIFF formats.
- MultiView OpenEXR support.
- Video and Audio player.
- Network syncing support.
- Non-destructive EDL.
- Grease Pencil support.
- Multi Part EXR images.
- Deep OpenEXR images.
- Animated GIF support.
- Color Transformation Language support.
- ACES 1.0 support.
- Passive 3D Stereo Support (anaglyphs, side by side, interlaced, checkerboard).
We found mrViewer’s layout seemed to be a little cluttered and it is difficult to understand the functions easily. That having been said, there are however, tooltips for giving you some hints to help you along.
The app does have some good features though, such as support for hotkeys, which can be reassigned, and it also comes with viewable log files. It provides information on filenames, size, ratio aspect, gamma, format, memory, and compression. For images, you can analyze a histogram, and it has touchscreen editing support as well.
Overall, mrViewer has some useful features but we found the interface not that intuitive and slightly cumbersome.
Made Scrubbing work with the left mouse button only. The default behavior of the left mouse drag is now scrubbing. There's no need to use SHIFT/CTRL combo. You can use the Action Tools Window (renamed from Paint Tools Window) to change it back to area selection, draw pencil, draw text or eraser, besides scrubbing. Removed the scrubbing shortcut.
Removed work-around for subtitles with ' as a sea of backslashes quotes the file just fine. Same with file paths with : in them.
Bug fixed adding subtitles to audio files only. This is not allowed.
Added missing movie extensions to file requester. Now: asf, avc, avchd, m2ts, m2t, ogm, ogv and ts are listed as movie files. Previously, they would be hidden.
Made file requester list appropriate files for file extensions when the file requester has already been opened once.
Made the EDL timeline follow the viewer's timeline so it will show the current frame when the EDL Window is opened.
Made EDL Edit window support PageUp/PageDown shortcuts to go to the next or previous image sequence/movie.
Made Compositing->Scale the BG image to the FG image size, when unselected, place the BG image in the center of the screen, instead of in a corner.
Made SOP GUI hide when in presentation mode.
Made SOP LUT update when switching images with different LUTs.
