I've been beta testing LiveGrade, an application "for interactive manipulation of live video", since it was released a few months ago. This software's biggest appeal for me is support for the Avid Artist Panel (formerly Euphonix MC Color).
As of the latest beta, the Avid Artist surface is working great. To be able to grade in realtime on the set with one of these is a joy. Additionally, the HDLink Pro 3D LUT export lines up very nicely in Resolve if that's where you'll be generating the color corrected dailies. Interestingly, it also exports a native Resolve .dat LUT but I've found that the HDLink export actually lines up cleaner. Using multiple HDLinks in the software is also working trouble free. LiveGrade still has some bugs to be sorted but progress has been steady.
