So Assimilate has released this free player called Scratch Play for both PC and mac and I must say it is really a mighty and useful one.

COLOR, now here's where starts to shine

MONITORING

and best for last EXPORT

Cutting long tables short, or not, you can watch (and listen) footage of almost everything, with metadata and SCOPES, LUTs and whatnot. You can compare between 2 clips, same clip at different time, sizes, with different colour settings/grades applied, different color spaces, LUTs, source mode mapping (Lin to Log, viceversa and Lin/sRGB, Log/Filmm Rec 709, Wide Gamut, etc. you can even load yours), 8, 10 and 16 bitdeph, different frame rate/speed (from 0.1 to 199), with different frame size or aspect, offset, with guidelines (2:35, 1:85, etc.), crop marks, color full range and gamma, timecode and 3D baby jesus snorting coke LUT if that's your thing. Here's another cool feature: you can export your LUTs. You can visualize RGB channels plus luminance or alpha only. It supports dual monitoring, makes fullscreen either in single or compare clip mode, you can completely fade borders, guides, etc. Scopes can be transparent or solid, has dedicate snapshot button, a magnifier... for sorting buggers :P and pressing tab (on mac) hides panels.

Now the "drawbacks" it is free with little stupid adds, you'll need a fairly decent powerhourse for all-in smooth performance, you may, just may like it.
