color correction stayed even though I removed it

Question

i was trying to color correct a video when i decided to scrap the whole thing an start from the begining again

so i use "remove all atrributes" but when i look at my footage it looks the same as it did before i eliminate the whole thing so now i cant add a new color correction because all my videos look over saturated or overexposed.

the footage i was editing was shot with an iphone i know that if you use rec 2020 it fixes how it looks but i dont know if maybe that was the problem

i just want to eliminate that color correction and i cant even open a new proyect because some how it remembers that the video use that color correction an it aplies it there aswell.

at one point i thought it only affect the preview but even when i exported that color correction appears on the final product

if someone had that problem and solve it, please send help

I think this is simply a problem of not understanding the new and frankly often confusing color management. And I work for/with/teach pro colorists btw.

First, although one can work in HDR, it is very much the Wild Wild West of video. Many screens can't do it at all yet, and those that supposedly can are all over the place in what they choose to do with the image. I don't really recommend working with that format at this time other than for learning processes.

So turning off the HLG/HDR setting of the iPhone is as a practical thing, I think wise. But you've already got HLG clips, so this is what you should do.

HLG Clips used in Rec.709/SDR Workflows

Select one or more clips in the Project panel bin
right-click Modify/Interpret Footage
at the bottom, set the Override-To option to Rec.709
with the Timeline panel active, set the Sequence Settings Working Color Space to Rec.709
turn ON the Auto-tonemapping option

Doing the above will cause Pr to bring those clips properly into the sRGB color space of a Rec.709 workflow. And will remap the dynamic range to within Rec.709 limits without clipping whites or crushing blacks. It's a decent starting point for "prettifying" the image in the Color workspace Lumeter panel by yourself as the next step.

If you really want to, I can go into an HDR workflow setup also.

Plus ... for Mac users, there is now a setting which might get you a correct Rec.709 image with both the camera and the display transform applied, which the standard Rec.709 in ColorSync does not..

Check your system or monitor settings for the option for "HDTV/Rec.709/Bt709 Bt1886" and use that setting. Then turn off the gamma boost option in those settings somewhere.
