Canon C300 Log10 To Rec 709

Hi everyone,

A while ago on another forum thread, someone posted aCineStyle LUT in .cube format which I'm using frequently, and was wondering if anyone made the same for the Canon's new C300 camera and it's new "Log10" LUT. I'm looking for this new "Log10" LUT for use in Resolve, which you can download as a .csv file here:

http://gdlp01.c-wss.com/gds/0/0200001940/01/CanonLog10ToRec709_ver1.0.csv

Did any of you succesfully convert it into a .cube file and use that LUT in Resolve? What software should I use to do this? Or can any of you post it here perhaps? :D

Thanks!

That's fantastic! Thing is, should I use the .cube or the Davinci .dat file, and also; where should I put it? :)

.cube should work.

Thanks very much for the CLOG LUT - I've been trying to get my hands on that for a while now!

It should not be converted to 3D LUT cube because the original *.csv curve is 10bits 1D LUT.
3D LUTs have much less steps than 1D LUTs, for this case making a Resolve's *.olut (output 1D LUT) is the best way to go.

I have *.olut versions of all original *.csv versions supplied by Canon.
-CanonLog10ToCineon10LUT_ver1.0.csv
-CanonLog10ToRec709_ver1.0.csv
-CanonLog10ToVideo_ver1.0.csv

However,

-I don't use CanonLog10ToCineon10LUT_ver1.0.csv because i don't know when to use it.

-The CanonLog10ToRec709_ver1.0.csv simply cut everything above 648 [of 0-1023] it's for someone who want to change the CLog images to Rec709 with hard clipping.

-The CanonLog10ToVideo_ver1.0.csv is the soft rollout version of The CanonLog10ToRec709_ver1.0.csv it's for someone who are not pleased by hard clipping Video look.

I find myself not to use one of them because after i converted from C-Log to Rec709(or Video) the DR is compressed, the tonal curve is no longer linear light, a bit harder to grade. I think those curve are for simple CLog-Video conversion such as transcoding original MXF to QuickTime for editorial not for color correction in postproduction. I'm searching for a white paper of Canon-Log ( like ARRI made one for AlexaLogC ) but i can't find it. Now i simply grade on Canon Log directly. The first node is Primary decrease the gamma, increase the gain and apply some soft clip if you like. The next nodes are series of Primaries/Secondaries. By this way i will get what i want easier.

Oops i forget one thing. I use plain Rec709 curve for output LUT.

Check out this link if somebody want to try *.ilut version of all original *.csv format.
