Adjustment layer
A transparent layer that applies one set of effects or color changes to every visible clip beneath it.

What it is
An adjustment layer is a transparent timeline layer whose effects are processed onto every visible clip below it. Instead of copying the same grade, blur, or stylization onto ten shots, place it once on the adjustment layer and trim that layer to define exactly where the shared treatment applies. The idea is borrowed from Photoshop, where adjustment layers have applied non-destructive changes to everything beneath them since the 1990s.
Reach for one when several shots need the same Lumetri Color look, when an effect should switch on across a whole montage, or when you want one set of keyframes to control a section. Splitting or stacking adjustment layers can keep a base correction separate from a temporary creative effect.
Gotcha: layer order and coverage are the control surface. The adjustment affects only lower tracks within its time span, and stacking two layers processes the image twice. A single global grade can also magnify exposure differences between shots, so correct and match individual clips before adding the shared look.

In Adobe Premiere Pro, create an Adjustment Layer that matches the sequence settings and place it on V3 above the full montage. Apply one Lumetri Color effect to that layer with a gentle S-curve and creative LUT intensity at 70 percent, then trim the layer so it ends before the untreated end card. Keep per-shot exposure and white-balance corrections on the source clips below, use Effect Controls opacity keyframes for a 12-frame transition into the shared look, and do not duplicate Lumetri on the adjustment layer.
