Set the colour grade of ONE clip in the edit (Murnau), or of the whole programme with `programm: true`. It is the same grade a colourist sets in Murnau's colour workspace, and the export uses it: Murnau bakes the export LUTs when you set it. Only the fields you send change (`zuruecksetzen: true` starts from neutral). Fields and ranges, as the sliders: exposure in stops (−5..5); contrast, saturation, temperature, tint −100..100; hue −180..180; lift/gamma/gain/offset as {x, y, master}, each −1..1 (x/y move the colour wheel); log as {shadow|midtone|highlight: {x, y, master}} — the Log wheels in ACEScct, each acting only on its range of brightness (shadows below ~4 % linear, highlights above ~50 %), master ±1 ≈ ±2 stops there; schritte as a list (≤ 8) of further grades with the same fields (plus name), applied in series after this grade — serial nodes; creative and sek stay on the grade itself; hdr as {dark|shadow|light|highlight: {x, y, master}} — HDR zone wheels centred −3/−1/+1/+3 stops around 18 % grey, master ±1 ≈ ±1.5 stops; curves as {master|r|g|b: [[x,y],…]} 0..1; boost, shadows, highlights −100..100; intensity 0..100 (0 = original). Per clip also `sek` — a secondary correction: {qualifier: {hueCenter, hueWidth, satLow, satHigh, lumLow, lumHigh, softness, invert}, fenster: [{form: kreis|rechteck|verlauf|polygon|bezier, cx, cy, rx, ry, winkel, weich, invert, modus: add|sub, punkte (polygon/bezier only: 3–16 resp. 3–12 [x, y] in the window's own unit space, scaled by rx/ry and turned by winkel — bezier draws a smooth closed curve through them)}], grade: {saturation, exposure, temperature, tint, hue, schutz}} — schutz 0..100 takes the clip's and the programme's grade back inside the selection (100 = ungraded there, e.g. to protect skin); `sek: null` removes it. Any level also takes `warper` — the Color Warper: {huesat|chromalum: {res: 6|12|24, punkte: [[i, j, dx, dy], …]}}; node (row i, column j) sits at (j/res, i/res) and is moved by (dx, dy) in −1..1. huesat plane: x = 0.5 + 0.5·sat·cos(hue), y = 0.5 + 0.5·sat·sin(hue) (lightness kept); chromalum plane: x = sat, y = 1 − lightness (hue kept). Only moved nodes; `warper: null` removes it. Call WITHOUT `grade` to list the clips (clip_id, start/end, current grade, input profile) and the programme grade. Measure first and after with lab_scopes — its `vorschlag.grade` is a computed correction you can pass here as `grade`. Writes state, costs nothing.
