 Can Lumetri Color work in real time in the Мulticamera mode ?I need the panel to work as quickly as in other modes. Who can fix it? I noticed this bug in all versions on different PCs

Can you provide more details about your media? Specifically, the codec and frame size you're working with?

I tested Lumetri Color on a multi-camera sequence using ProRes HD footage on a relatively old and underpowered MacBook Pro. Despite the hardware limitations, adjustments in the Lumetri panel were smooth and responsive.

Knowing your media specs will help identify if the issue is performance-related or possibly linked to another factor.

h264, 264, mp4, mov, 24,25,30,50,59 fs.  frame size was no difference, at least 4K or 320 by 240. Bitrate is also different - 2 or 100 MB. I think Adobe works incorrectly in the Windows system

I am totally PC, have been for many years. Using Premiere across desktops abd laptops since CS6.

 

Premiere works very nicely on properly chosen hardware.  Or perhaps I should say when your hardware fits your media. 

 

Long-GOP media like you are using is the nastiest media to use period. A heck of a lot more demanding on hardware than 8k Red log.

 

So what in detail is your rig?

Lumetri is a very heavy effect in computational load. Not quite as heavy as Warp, which even exceed Neat video Noise Remover ... but getting close.

 

Multicam is throwing however many different vide clips at a time at the computer's capabilities, which can stress many rigs. Now throw in a massive effect like Lumetri ... you see the problem?

 

But past that, I never do color work on the multicam 'sequence' itself, it's a time suck.

 

I drop the used clips on a new sequence, trim to just a couple seconds of each ... grade each clip to neutral then to match ... copy each clip's Lumetri, and paste it on that clip in the bin. Delete that shor little grading sequence.

 

This is a "source effect", which now is applied on all instances of that clip anywhere in that project.

 

And done that way, doesn't seem to slow up my rig while cutting the multicam.

I want to add +1 to brightness. This action takes 10 seconds. This is not normal

They don't have keyboard shorts for such things, and yea, that's annoying.

 

But then a panel is far faster than even keyboard shorts, as things are mapped to bits on the panel already, and I don't have to select anything. Just for brightness, rotate a dial.

 

Which is a small part of why panels would speed up so much work ... the Tangent ones, for instance, can be mapped to everything from sizing/rotating/positioning any selected screen item to audio mixing to ... whatever.
