Multicam seems not show size change of angle bug or i miss

today i start with two different shooting did for a simple theater show of child.
two cam, first main camera and second cam to grab different angle.
I build a UHD timeline where i put main cam (angle 1), second cam at sinc (Angle 5), and i duplicate main cam three time with different size (zoom) and position drag to build virtual 3 angle (angle from 2,3,4).
I convert this timeline in a new multicam and seems to see all different angle

but when i grab it to put in a timeline to edit like multicam i cannot have original preview, but all virtual angle seems reset their transform preview

but only preview be cause if i cut multicam, in the program monitor i will see correct picture.
i tried to redo it also with a compound for every single virtual angle, but nothing.
i tried with the last official 18.1.4 and with 18.5b3, same result.
Any suggestion where i'm wrong?

Sounds like the Multicam preview is going to the source-clip level, doesn't it? Maybe you could try to duplicate the clip in the media pool for your 3 virtual angles (one for each) and perform the inspector changes to the source clips and then insert them into the timeline to trick Resolve into seeing those changes in source.

I haven't tried this yet so I may be totally wrong, but it's an interesting problem. If I get some time I will give it a quick try.

This is a weird gotcha with Multicam.

I think you'll need to export out three Intermediate files of the different Zoom levels and bring them back in as separate clips.

But is weird be cause only preview multicam do this, the multicam clip in timeline reflect right size and translate.
And double weird to me is that also with compound (which should create a newer original) do that.

Yes - I gave my idea a try and it doesn't work. I would call this a bug because somehow the Multicam switcher doesn't consider any source tweaks and goes straight to the reference media for its preview thumbnails. I suspect this has been a long-standing implementation detail. Unfortunate, to say the least.

Yes the multicam preview is the source. That is why now I flatten after just cutting. Even cutting to the same camera when I want a different framing from it afterwards. Now at least the color page settings are carried over in the flattened file. But I now just cut then flatten and do everything else on a second pass. I think the value of seeing the full original file in multicam preview is one can then see what can be cropped, zoom, pan etc later.

i will send like a bug to dev team.
i solved exporting more version of original movie to do the editing of different angle.
thanks for all effort.

A workaround is to use the Transform Open FX to adjust the zoom and position of the clips.

How does that work ?

Open the multicam, drag the Transform effect from the effects panel to the clips you want to transform, adjust the zoom/position of the effect. This way the transforms will be visible in the multicam viewer during editing.

Sorry don't follow this at all. The multicam clip is one compound clip. You only see the clips that are part of this in the muticam viewer. How do you apply the transform to theses clips?

Right click on the multicam and select "Open in Timeline". Apply the Transform OpenFX to the individual clips inside the multicam. If you go back to the main timeline all the transforms you made inside the mutlicam will be visible in the multicam viewer

Yes but I do not want to use the same zoom, pan etc on the whole clip. Just when I select it I use a different one each time to get the framing I need for that point in the edit. Which is why I do after flattening. Then I have the full clip resolution to use. In my case either GH5S C4K or GH6 5.7K in a HD project. You could do what you suggest on the original clips with the inspector before creating the multicam clip but again just one instance.

My reply was for the OP's problem.

If I'm not mistaken, he duplicates the main camera multiple times to new angles, on each duplicated angle he applies a fixed amount of zoom/position to be able to quickly switch between them.
By using the built-in transform of the clip, all duplicated angles with different zoom levels look exactly the same in the multicam viewer preview during editing. This is why I suggested to use the Transform OpenFX instead.

yes that works good. Even get back to source resolution if flattened.

Yes you are right and solve my problem, thanks a lot
i not thought to try by transform OFX

Surprised that this works. Points to some very odd behaviour of the Multicam viewer, doesn't it? Glad to have this sorted. Thanks to panos_mts for the suggestion.

what surprice me is that coumpinding clip not resolve, an OFX resolve the problem of Preview.

in theory from Operation order should work fine like first operation (screengrab from manual), but work in timeline, not in preview, mean somewhere someone forget to read from preview this kind of operation.
i sended like bug, we wait that resolve it.
Now thanks to Panos_mts i (and we) have solved the day
thanks again.
