Thanks - that's a great video (although Rec 709 would downgrade HLG Rec 2020 footage if I want to preserve HLG for Youtube etc). I guess the key question is what the correct Input Colour Space for M4P HLG video is? I assume that the offered DJI D-Gamut is for D-Log footage only?
Hi, you are welcome!
And that's the beauty of Color Managed editing, your footage from M4P is 10bit BT.2020/HLG and if you import HLG clip into DVR and use in Project settings > Color Management option 'DV YRGB Color Managed', your clip will be recognized as Rec.2100/HLG automatically and the basic color grading will be adjusted immediately.
This is an automatic way to properly set the input color space (gamut). All additional adjustments (on timeline) will be running in a very wide gamut, so the information will not be clipped.
And you can set as output format in your project also HDR, if you like, there is no need to export everything in Rec.709/Gamma 2.4. I'm using SDR/Rec.709 for output, that's how I have my project set up. And you can also "manually" control it via CST node for example :]
It's a pity that DJI only allows either HLG+wide gamut or LOG+Rec.709 in M4P. So yes, you can shoot videos in LOG, but neither combination is quite perfect. If P3-D65 or the same gamut as HLG (Rec.2020/2100) were possible with DLog-M, for example, that would be ideal. But I understand that this is marketing strategy ;] |
