SerialB Movie Studio

RED Camera Rental-Color Grading-DCP Creation

Here is the result : everything seem to work, i will make new test tomorow but for the first try i’m quite happy.

Here is what i do :

– export my entire film from davinci in prores422 HQ REC709 unscalled full range.
– upscale and convert in TIFF 16 bits 2048×858 REC709 (lin luma)
– do the REC709 TIFF to JPG2000 XYZ in openDCP

I have a little désappointent with chroma level, little desaturation after XYZ conversion (3 or 4 % desaturate) but my black are black.

Do you think i have to adjust a little my chroma level in Resolve ?

[Jean-christophe Savelli]

It’s exactly what i finally done a node with black lift adjusted and a small gamma adjustment in the mid tone.

Thx for the information Knut so i look in the manual but i don’t exactly know what i’m looking for ?
something like “1d lut gamma compensation” ?

[Jean-christophe Savelli]

it seems that you are involve in opendcp, i have a small question.

in the jpg2000 creation window, i see that we can select both sRGB or REC709 as input source. Does it meen that opendcp jpeg2000 can simply and easily convert REC709 source to a good XYZ version without need to adjust source in full range mode ?

[Jean-christophe Savelli]

Ok i will do some test with AE for the export : both with full range and limited range to compare.

And yes you right Juan, the image will be darker, it is because i’m quite worry about that gamma question a the best solution to have a final dcp close to my graded 709 version, even the 709 gamma is 2.2, 2.4 or 2.5 it will be darker in DCP and i need to find the best solution to manage this.

thx chris i do it by myself because i don’t have the money to let a company doing this for me.

Waht i plan to do after reading all your advices :

– don’t touch my grade, keep it in rec709 and in legal video
– upscale to 2k (2048×858, 2.39 ratio)
– export from resolve in dpx sequence still in rec709

i will use opendcp to create the dcp package. I see in opendcp that we can feed with rec709 dpx sequence.

Is it something bad with this workflow ?

[Jean-christophe Savelli]

Thanks for the link Jack.

So for Davinci user, do you think a need to check all my grading with unscalled full range activated or not ?
