Question

Please could someone show me the workflow for colour grading a camera in a multicam sequence?

I've spent days pulling my hair out with Adobe technicians who tell me I have to colour grade my clips BEFORE I can bring them into a multicamera sequence.

Firstly, this makes no sense to me. Premiere allows me to add Lumetri Colour to the master (source) clips, in the Bin window. It allows me to edit the curves, but then it crashes. Every time:

Bug: Premiere: Colour grading one angle in a multicam sequence.webm - Google Drive

Surely a crash every time = a bug? There seems to be no acknowledgement of that from Adobe. I just get told I have to colour grade before I bring the clip into the multicam sequence.

What if I find the light has changed half way through my multicam edit? Is it too late to make any adjustments to the colour grade? That strikes me as painfully bad design. Either way, why does Premiere allow me to do this if it's just going to result in a crash!

How do you colour grade your camera angles (independently) in a multicam sequence, so all camera angles match each other?

Is my issue happening because I started by automatically syncing my clips using the 'sync using audio' feature? Surely that can't be the cause of this problem? I don't want to have to manually sync every clip into the multicam sequence!

Thank you so much for any help.

I'm already pushing the deadline on this project from days of wrestling with this issue and Adobe's dysfunctional support system with invalid phone number (you can't call a number starting "800" from the UK and Adobe know I'm calling from the UK) and live chat doesn't work - I just see the old live chat where the previous technician cut me off because I didn't reply immediately after I waited 20 minutes for them to arrive.

I'm having something similar 

opening multicam on timeline to adjust color the cameras in that multicam
it is a regualr occuring crash I can't eliminate 

generally getting, after crash out of premiere,  there appears a problem report that lists
