Colour Panel¶
The colour-grading controls for whichever layer is selected in the Layer Stack.
COLOR tab¶
Ten scrubby controls — scrub to adjust, double-click to reset:
| Control | What it does |
|---|---|
| Lift | Adjusts shadows (primary colour-wheel equivalent). |
| Gamma | Adjusts midtones. |
| Gain | Adjusts highlights. |
| Offset | Shifts the overall exposure/colour uniformly. |
| Brightness | Overall brightness adjustment. |
| Contrast | Overall contrast adjustment. |
| Saturation | Colour intensity. |
| Hue | Rotates colour around the colour wheel. |
| Shadow Lift | Lifts or lowers shadow detail specifically. |
| Highlight Rolloff | Softens or hardens the transition into clipped highlights. |
A scope display sits alongside the controls for reference while grading, switchable between two modes from the "EDITING: LAYER N" row:
- WAVEFORM (default) — dual-mode luma or RGB parade.
- VECTORSCOPE — hue/saturation distribution. No longer a separate panel (it was one before 2026-08-15) — this in-panel toggle is now the only place to reach it.
The skin-tone highlight toggle lives in this same scope header, regardless of which mode is active.
MASK tab¶
Holds the qualifier controls (HSL, RGB, Skin, Luminance) used to target a correction at a specific colour range instead of the whole frame. See Masking & Qualifiers for the full reference.
Switching to the MASK tab automatically switches the Viewer to Active Mask mode, and vice versa — the two stay in sync in both directions.
SEGMENT tab¶
Shown when the selected layer is a Segment layer (added from the Layer Stack with + Segment Layer). Qualifier and shape tools are not used on this layer type — the Mask tab points you here instead.
Type a short subject in plain language ("person", "red jacket", "the dog") and click Segment. Transduce tracks that subject across every frame of the clip in one pass, not frame by frame. + add subject adds another prompt to the same pass; Add / Subtract on each subject folds them the same way geometric shapes already do (union, or punch a hole). A second Segment layer is the intended path when a distinct subject needs its own refinement.
Per-layer matte refinement (Despeckle, Hole Fill, Feather, Expand, Intensity) runs once on the folded result of all enabled subjects on that layer — the same engine as the Mask tab, not a separate per-subject set of knobs. While a pass is running, Segment becomes Cancel; after a successful pass it reads Re-segment.
If the model weights are not installed yet, Download SAM3 (~3.3GB) appears instead of Segment. See Masking & Qualifiers for the full reference, including Mask Lock.

ALPHA tab¶
Post-processes the combined per-clip alpha — the matte accumulated from every layer whose A+ or A− control is contributing (see Layer Stack). Opening this tab auto-switches the Main viewer to ALPHA.
A levels row (Gamma, Lo, Hi) is Alpha-specific. Below it, the same despeckle / hole-fill / expand / feather / intensity strip as the Mask tab, plus Invert. Until at least one layer is contributing, the tab shows an empty-state note instead of the controls.
Delivery of that matte — embed, standalone sequence, Cut Out — is configured in the Output Panel.
