Hi,

I've got a bunch of 3min headshot interviews with a dull background, which I want to blur a little so using the MagicMask for the subject, then the Defocus Background effect for the background. It works really well on the source clips, but I run into problems with multicam clips.

They're two-cam multicam clips and applying the process to one of the angles in the 'open in timeline' view of the multicam clip doesn't work; when I go back to the main timeline the defocus is applied on the whole frame, not just the mask/background. Same thing happens if I use the blur tool or the Lens Blur effect.

If I finish the edit, then flatten the multicam edit I can apply the process to each shot that needs it, but is there a way to do it on the original multicam clip (i.e. one angle of the multicam) rather than each individual edit once flattened? Ideally I want to apply the effect on the whole clip, wait for it to track the mask, then edit as I need to.

Thanks.

Just tried and not seeing the problem you describe. Any chance of uploading a small sample archive illustrating this issue? Upload it to a file sharing site and post a link to it here. Cheers.

I also find this working as expected in Studio 20 for Windows.

Thanks - tried again today, same steps and it's working. It's a mystery.
