warp stabilize with multicam and lumetri effects

[BrianWilbur]

I have found that warp stabilize works much better when a multi-cam clip is flattened.  This copies over any underlying lumetri settings ok, but does not allow for any subsequent lumetri color changes to the underlying footage.  If I update the color settings on the source footage, then I have to manually go and update the lumetri settings on any sequence that has been flattened for warp stabilization purposes.  I'm open to suggestions for a better work flow.  Including possibly:

• Having an option for a lumetri setting, when updated, that could also update all the other clips with the same preset on them.
• Fixing the warp stablize so that there is no need to flatten the clip.
• Having a search and replace effects function to do a mass update on any lumetri settings that need updating.

Warp is incredibly hardware-intensive. As a practical matter, I don't apply Warp and Lumetri and other things on a single track sequence ... on a rig with 24 cores, 128GB of RAM, and a 2080Ti GPU. With everything on high-speed internal SSD drives.

Once I get a good "Warp", I immediately do a full render & replace to something like ProRes 422. That way, Warp is done. And I don't get weird or sluggish behavior after applying other effects.

For the same reason, any Ae comps I do ... when 'done', export a file from Ae and replace the comp on the sequence.
