Premiere Pro Effect controls loosing focus for multicam sequence

While this exchange is internet gold, Andrew is right in the regard that this is certainly a bug. 

Andrew, I just encountered this. I (as for now) fixed mine by restarting Adobe and clearing the Media Cache. 

@R Neil Haugen 

My workflow is like this:

- create a multicam (2 cameras)

- duplicate the 2 clips and nest them > make a side-by-side splitscreen > add the nest in the multicam sequence as a 3d camera

- cut, add motion graphics, make a teaser

- give to the client for review

- once the project has been approved, grade it fast. The fastest way to do that is to lumetri-color the 2 clips inside the multicam sequence (they always demand a different colouring since they are 2 different cameras from different locations). Copy-paste the lumetris to the other two clips inside the nest as a 3d angle.

The two problems I've faced with in the current version of Premiere Pro are:

1) if you accidentally double-click the multicam sequence in the master-sequence and thus open the multicam in the source monitor, instead of ctrl+double-clicking to actually open the multicam sequence, you will get this bug I described it the header message - until you manually close the source monitor tab Premiere Pro will lose focus on every action with the clips inside the multicam.

2) This one is even worse. At some point Premiere Pro starts showing black screens in the clips corresponding to certain angles. It looks like this:

And before you point it out - no, inside the multicam all the clips are enabled. So you can see them in the multicam and you can see black screens in the main sequence where the multicam resides. Moreover, if you switch the angle - some angles are shown fine, some are black.

I first thought that might have been related to the first issue, but in the next project I did not color-grade anything and still got it. I do not use any effects inside the multicam, so I thought it was the Lumetri Color to blame. I was wrong. Then I thought it happened because of some other changes inside the multicam. I normally correct the people's position in the frame by moving the position property and scaling them up. One thing I noticed is that it only happened when I did this in on the Properies panel, not the Effect Controls where it was fine. But yesterday I tried to reproduce the issue on purpose and I failed too - changing the properties in the Properties panel did not cause it.

I also sent my project to a colleague and he had no issue while it happened in my Premiere Pro. 

Two more things to mention - I completely reinstalled my Windows 11 24h2 and installed Premiere Pro with no plugins and this issue happened again. And I could fix the issue several times without the need to remake the multicam sequence from scratch having flushed the media cache. At the same time resetting Premiere Pro did not help. So I conclude that something causes cache corruption, but I have no idea what.

Another problem is that I have VERY tight deadlines (like making a project I would normally make for one day within a 3-4 hours span) and this issue happens just before I'm gonna finish and render. This really kills me. And I cannot do it in Davinci because the company uses Premiere Pro.

lt looks like you're grading while in the 'nested' view of the MC "clip" ... is that correct?

R Neil Haugen

please, don't take it to heart. I know you wanted to help.

Meanwhile I've reproduced this issue several times already and there is a clear pattern. I'll update this message later.

Rarely have I had such a snarky response. As if you're the only one that actually "works" or something?

I don't understand that attitude. So have a nice day.

And take all blasted day to do what I get done in a minute or two.

R Neil Haugen, thanks for your input, but I don't have so much time to discuss an obvious bug and your workflow or experience. I have work to do.

I don't understand the snark anymore than your workflow ideas. 

So as someone who's done this professionally for over a decade, I'm struggling to understand your answer. Because I try not to work stupid and waste time while working, when there's a cleaner faster (and less boring) way to do something.

A multicam typcially has what, two to five or six cameras? Something like that.

Quite often, the cameras are on the whole thing, though sometimes some cameras go on and off. But still, there are only X number of cameras, and the operators aren't normally stupid enough to change camera settings everytime they start/stop if they do start/stop through the shoot.

You go down the sequence 'cutting' from one camera to the other, but typically, no matter how many cuts, you still only have those two to six or whatever clips. Or cameras.

With (normally) one setting for each camera.  

Pasting a Lumetri to a clip on the bin changes every instance of any bit of that clip, right? In Premiere terms, that's a Source Effect.

So I grade one set of frames of each of the two to six camera setups in use, quickly. Then Paste that Lumetri to all uses of each camera, which takes a few seconds. Premiere then applies that to every segement used in the multicam.

And I'M DONE.

I don't go down a multicam grading each clip segment because that would be an incredible waste of my time.

And I also work in Resolve, with/for/teach pro colorists ... and Resolve also has clip and group processes to do essentially the same workflow.

I never ever grade every segment of a multicam as again, in either app, as ... jeepers, what a massive time suck that would be.

Should we have an option to work effects while in the Source monitor? Could be useful, certainly. As I understand things it's just not how it's been envisioned so far. I think that would be a nice new user option.

R Neil Haugen, good for you, but it doesn't solve the problem. Copy-pasting lumetri to each clip is like a 1st year learninng Premiere Pro, pros won't do that., those on short deadlines NEVER do that. Color grading multicams is done within multicams both in DVR and Premiere Pro. You just waste your time copypasting grades to each clip, especially when you have to make versions of it. Grading inside a multicam is as simple and time awarding as grading a source.

But your way is your way. The bug still exists.

Premiere always defaults to the Program monitor and 'normal' timeline focus for grading and many effects. To the point I've never tried grading in the Source monitor. That's not what that is for, really.

Although I also never grade multicams per se ... I always create a grading sequence of the files used in the multicam, cut them to just a few frames each of the best frames for comparing apples to apples, do my grading. 

Then copy the Lumetri effect for each clip and paste that to the clip in the bin. After that, delete the grading sequence. All grading is done then.
