mrViewer is a small image and video player which supports many of the most popular image and video formats such as JPG, PNG, BMP, PSD, MAP, WMV, AVI, MOV and several others.
As a portable application, mrViewer does not need to be installed but just executed from a USB thumb drive if needed.
Featuring a modern, dark and user-friendly user interface, the program still has its drawbacks and may seem a little bit complicated for first-time users. With that said, mrViewer is still a powerful application which has several good features for video playback like frame-rate, changing RGB values and changing the gamma levels.
For image viewing, mrViewer provides the option to edit photographs, change size, change gamma/exposure and other common image enhancement utilities.
Other features include hotkey support, histogram, compression, network synchronization and viewing images as a flipbook.
