Color correction before or after color space conversion (Override Media Colorspace)?

[Erik Patak]

Hi folks,

I cut a multicam sequence together, and then forgot about color correction, which I ideally would like to do on the source clip. 

Premiere rolled out their color space conversion options, which can be found either in the settings tab of the color window (which affects the source clip). Annoyingly, you cannot view the source clip with this color space override applied, only in the sequence monitor. 

When I apply an adjustment in the lumetri panel to the source clip - I can't see the CST applied - only the log footage. I also don't know if it's applying this adjustment before or after the CST. This is counterintuitive to the DR workflow I'm used to, where my viewer has a transform node after my adjustments. 

My question is this - where in the chain does this "override media colorspace" option apply? I want to make my corrections BEFORE this transform, to preserve data. My alternative is to nest all my clips of the same source footage (annoying after cutting), apply an adjustment layer, then find at log-rec709 LUT and apply it to the CREATIVE tab of lumetri to make sure I can make my adjustments BEFORE the conversion. 

Looking for tips on a better workflow. Thanks!

I tend to put clips from multicams on a new sequence, cut to just a couple seconds of each clip. Do one, match the others to it.

Then copy/paste the Lumetri effect for each clip onto that clip in the bin.

Then dump that balancing sequence.

That way it's a cleanly matched final multicam with only doing each camera once.

Got it, that makes sense! I'm curious if the adjustments made to source clips are applied before or after the built in color space transform options that Premiere has. 

Thanks!

Easy to figure. Look at the ECP ... when in Source tab.

Top to bottom, of course, is the way everytying is porcessed. Color changes are naturally first. As are any RAW panels.

Well that's just the thing, the "settings" tab in the color workspace (also found in the interperet footage options) doesn't show up in the ECP, even for source clips. 

Rather, it shows up under the color workspace settings, where in the "edit" tab you can toggle between source and timeline clip. 

But the CST in the "settings" tab does not appear when you click into the source tab. 

Is this considered a RAW panel? Sorry, I swear I'm not being intentionally thick. I just would like to know if that "override media colorspace" option comes before or after any lumetri color effects. If it comes before, then there seems little use in using that option in a log workflow, as you clip all of your dynamic range before you are able to adjust it.

As noted, color space is first. Then anything added to the Source in order. The anything added on a sequence, in order.

Raw panels are very obvious, for Red, Arri, or BlackMagic raw files.
