Me and my collegues have updated one of our birds to new firmware V01.01.0200.
Our main concern is NEW D-Log, which still has THE SAME NAME while it is COMPLETELY DIFFERENET from THREE PREVIOUS VERSIONS (there was D-Log for X3, then original X5 D-Log succeded by improved original X5S D-Log, then D-Log 500, and now we got D-Log D-Gamut).
Then there is question - ist there any offical specs for this new D-log for X5S? I have found D-Log D-Gammut whitetpaper next to X7 camera, in which that X7 is not mentioned anywhere!
https://dl.djicdn.com/downloads/zenmuse+x7/20171010/D-Log_D-Gamut_Whitepaper.pdf
While X5 is mentioned in several places in that document - is this whitepaper valid for X5S? Why it is not published next to X5S camera or next to I2 drone?
Then there is new "D-Log to Rec709 LUT" published next to X7 camera - is this LUT valid for X5S as well, and is it calibrated just for EI 1600 as per whitepater?
Our first test of new D-Log brought worst of the problems I have enconter with old X5 camera - when recording low light footage at modest ISO 400 on SD card there is color banding/posterization and flickering are all over the place in H264 recording. Then there was significant ghosting in shadows. Even dalylight footage on fogy day have very strange uneaven colors (some neutrals are pinkish, some are greenesh, some are purple - color balancing is imposible in post as all of these are in the same frame)... I share some detail crops from screen grabs - shot with EI400 - please note horizontal color waves and ghosting... I would gladely share actual footage with you but I am still not allowed by the clinet, who still has to decide what should we do with such messy recording. I am very disapointed at the moment.
Do I understand correclty that EI 1600 is beseline sensitivity in new D-Log, while other lower senitivites are derivatives of that base one?
Are there any guidelines for proper D-Log D-gamut exposure and post workflow in Davinci Resolve or Premiere Pro or FCP X?
