MultiCamera Clip Not Scaling Properly

This could very well be user error, but I'm pretty sure I'm doing this correctly. Please advise if I missed something in the manual.

UHD Multi Camera Clip 3840 x 2160.

Edit the clip into a 1080p HD Timeline.

Scale the clip to 50% to fit the HD Timeline. The UHD image is cut off rather than scaling down.

If I "Open In Timeline" and edit the clips into the HD Timeline they scale down as expected. But not from the MultiCam Viewer.

Again, this could be operator error but from what I have found in the manual it appears I'm doing this correctly. See the attached image.

Update, the scaling works after I flatten the clip. But that defeats the purpose of a MultiCam clip allowing me to change the angles until I picture lock the edit.

Resolve is functioning correctly. You need to make your scaling adjustments to the original clip, not the multicam comp. (That's why it works when you Flatten it.)

What's weird about your explanation is that the Reference Manual says that Multicam Clips operate in the timeline just as any other Clip. This is page 517 of the Reference Manual. Am I missing something here?

The Scaling is being performed on the Multicam Clip, which is essentially a Compound Clip, or Nested Sequence if you're familiar with Premiere Pro.

The results you're looking for require you to Scale the original clip.

Ok, thanks for the info Jim!

Actually thinking on that further it doesn't make sense. The Multicam Clip is 4k resolution. So a Nested Sequence that is 4k in Premiere Pro would allow me to scale it down if I place that Nested Clip into a HD Timeline.

I MultiCam Clip in PremierePro that is 4k can be scaled down in an HD timeline.

So it really doesn't make much sense to me that a 4k original MultiCam Clip cannot be scaled properly in an HD timeline. There is still the extra real estate in the original mutlicam / nested timeilne that's being inserted into the HD timeline.

I just went back over to Premiere Pro to confirm I can scale 4k MutliCam clips in an HD timeline and I can. It's weird that Resolve won't allow this.

It's a similar deal trying to nest timelines of different resolutions, Resolve doesn't properly respect the resolution of the nested timeline, it just applies a centre crop.

Thanks Tom for the input, much appreciated!

Visualize it this way.

The Multicam clip is a picture frame. The original clip is the picture inside that frame.

If you scale the frame, you won't get the desired results.

If you scale the frame, you won't get the desired results.

Unless you use another NLE, in which case you will.

It's a bug, or an inadequate feature. Not something to settle for.

Unless you use another NLE

That may depend on the NLE. Premiere Pro works the same as Resolve.

Personally, I think should work this way as it gives you the ability to scale both ways.

these kind of the "functionality is correct" replies don't half wind me up. There is not another video editing program that doesnt hold its features when you flatten a multi clip. I feel your pain mate and for the record not only does it loose the scaling it looses all nodes meaning you cant grade a mulitclip so you better be sure of any edits before you flatten it

hi guzs, so this behaviour is still in V17 / is there any way of dealing with this?

i have massive timelines, with only multiclips. for delivery in 16:9 its all fine; but i have to reframe for 1:1 as well ... and the center crop really is a pain. i have to source-match frame each edit to get the source from mediapool outside of the multiclip.

any way to tell the nest to keep its original 16:9 so i can position the clip without getting black borders?

thanks a lot

What happens if you keep the timeline processing resolution in the original format, and only switch to the 1x1 via output resolution?

You should check Project Input Scaling settings. This setting affects how scaling of clips, compound clips & timelines work when used in a timeline of different resolution.

For scaling a UHD or 4k multicam clip in an HD timeline set scaling to "Scale entire image to fit".
4K may be better with "Scale full frame with crop" if you want to avoid the slight black bars.

There is actually a SOLUTION!! and its a feature of resolve

You dont set the timeline resolution, you set the Output resolution. that way you circumwent the croppping behaviour.

Leave timeline settings in original format

deselect "use timeline settings" and set the output format -> tadaaaa!!! its working!!
