Wondering if Sony Catalyst Browse lists SGamut/SLog2 as 'User defined curve9'
#9 Hi folks, I instructed a shooter with an FS7 to shoot in SGamut3.cine/SLog3, but I'm almost certain that the footage I got back is SGamut/SLog2. Catalyst Browse is telling me that the capture gamma is User defined curve9. How cryptic! Can anyone confirm that User defined curve9 is indeed SGamut/SLog2? Thanks, Seth Goldin Washington, D.C. |
#10 As I recall, in addition to the standard set of gammas the FS7 allows you to load custom gamma curves. 'User defined curve 9' would seem to be one of those... (If there's no signature it means I have the signature screwed up on the web interface....) |
#11 In theory, a 'user defined curve' is just that - something the user created with a program (Catalyst Browse for example) or downloaded from someone who did and then loaded it into the camera. Without a more descriptive name, I'm not sure if it is identifiable beyond that through some sort of reverse engineering. Steven Gruen Paris, France |

Thanks for this. A clue was that the 'Monitoring descriptions' listed SLog2. Regardless, I created my own custom curve in Resolve. I had been hoping for a quick and easy LUT for dailies like the SGamut3.cine/SLog3 to LC709A, but a custom curve with some LAB color contrast expansion sufficed. |

Unfortunately it seems that Sony is somewhat opaque when it comes to any API for XAVC, so I don't believe Resolve has any such access to reading metadata from the files. As far as I know, Catalyst programs like Browse or Prepare provide the only way to read the metadata. |

To get log gamma back to something looking good at 2.4, I finessed a custom curve in regular 'YRGB' space, just with all four channels linked. Then, to pull the chrominance out for an SGamut source to a 709 target, I switch to LAB color space and then just finesse the 'A' and 'B' curves. By doing this, you get a lot more control than just cranking the Saturation control in YRGB. I picked this up from Patrick Inhofer. He has a great series on this over at Mixing Light. |

I’ve used LUTCalc to create an SLog3 to LC709A LUT in the past. With the various customization features it has, it’s very simple to add a gamma tweak. Stuart Brereton |

#19 Can confirm the LAB trick - I’ve used that a bit before. Great for playing with saturation without skin tones going crazy. Thanks for tip on LUTCalc, looks like a very handy little tool.

#20 I've played with LAB in Photoshop and created some very cool looks with color contrasts. I didn't know it was in Resolve, although I'd long wondered why this wasn't a secret colorist tool. Maybe it was and I wasn't worthy of the secret. :) Thanks! -- Director of Photography |

There are all sorts of metadata in XAVC-I and XAVC-S that are not accessible in Resolve's Metadata panel, but those metadata are indeed available in Catalyst Browse and Catalyst Prepare.

#40 _____________________________________ Thanks Seth, I appreciate the correction. I might actually have to use Catalyst Browse occasionally. I usually shoot Slog3/S-Gamut3.cine and don't usually have a problem in Resolve but I know getting footage from others can be a nightmare.
