Lumetri Color should support multiple clip selection!
The Lumetri Color plug-in currently does not support multiple clip selections. This is unfortunate as this forces us to use multiple adjustment layers instead of one.
Imagine we have footage from different cameras. Once all clips are laid out we could add one adjustment layer and cut it on each clip's boundary, then apply per-clip corrections (say, colors-space conversion depending on shooting mode or camera model) using the Basic Correction layer, then use the Creative layer to individually make them look uniform or whatever.
Then we'd multi-select the entire adjustment layer, now made of multiple segments aligned to the video clip boundaries, and apply Color Wheel, HSL and Vignette to all of then at once, resulting in a single segmented adjustment layer performing all three steps: the initial color space conversion, the individual adjustments, and the overall look, all with ease and on a single layer or no layer at all, acting directly on the video clips.
Does that make sense?
Enabling multi-selection requires a bit of work (like tri-state or gray-out the options that are not uniform across the entire selection) but the end result would be better as we'd do one transform instead of three, so less quantization noise I presume? At the very least it would be more convenient/faster to be able to set properties on multiple clips at once!
