Canon 5D Cinestyle Technicolor Footage in FCP
on Feb 23, 2013 at 8:04:20 pm

Hi,

anybody had experience with following phenomena: I am working currently with 5D Footage, shot in Technicolor's cineStyle Profile. I ingested the Footage as ProRes QT through L&T Tool of FCP.
Experimented with some basic draft of the CC in FCP, using Colorista ll and 3-way color corrector.
According to my Waveform monitors I have a decent lighted image, but for some reason on export it darkens tremendously. Is that normal for this kind of footage and I just have to take it into consideration during grading?
Thanx a lot of sharing any thoughts about this one.

• Are you color correcting to Final Cut Pro's Canvas or an external monitor going through a converter? (AJA, Black Magic, and Matrox are common manufacturers)

• After export, where are you noticing the darker video?


The skinny of it is video on Final Cut Pro's Canvas isn't finishing quality. If you want to undertand it fully* it would be worth reading up a bit about gamma. The main idea is to optimise the image we change how electronics interpret the signal, but we have to later apply a corrective, and inverse gamma shift. It's the same idea as Cinestyle, you make the image look "worse" because after correction it's better.

* Beyond the gamma differences there are additional color space issues going on. HD video lives in Rec. 709 which has a luma channel and a pair of chrominance channels. Computers work in RGB, a channel for each of the three colors that make up the display.
