The two stages, and why the order is fixed
Colour work splits into two jobs that get collapsed into one word in casual use, and keeping them apart is most of what makes a scene hold together.
The first job is correction. Every shot gets brought to a neutral, consistent baseline: exposure set, white balance neutralised, and each angle matched to its neighbours so that cutting between them does not produce a visible jump. This is objective work with a right answer, and it is unglamorous.
The second job is the grade. Now that the scene agrees with itself, one creative decision can be applied across it: crush the blacks, cool the shadows, warm the skin, lift the mid-tones, desaturate the greens. This is where the tone of a sequence is set.
Reversing the order is the classic failure. Grade first and the differences between shots survive underneath the look, so instead of one scene with a mood you get several shots that are each wrong in a different way, and the cut announces itself every time.
What the grade actually controls
- Contrast curve. Where black sits, where white sits, and how the mid-tones roll between them. This carries more of a look than colour does.
- Shadow and highlight tint. Split toning, and the source of most recognisable film looks. Cool shadows and warm highlights is the dominant convention.
- Saturation, selectively. Pulling one range down, usually greens or yellows, does more for a look than a global saturation move.
- Skin. The one region the audience judges without knowing it. Nearly every grade is a negotiation between a look and keeping skin plausible.
- Print emulation. A film-style response curve with soft highlight roll-off and a slight cast, which is what most people mean by cinematic.
Grading cannot recover what the capture destroyed. Clipped whites have no texture beneath them and crushed blacks have no separation, so a grade that reaches into either area produces noise or flat mush rather than detail.
Grading generated footage
Generated shots present the opposite problem from a real shoot. On a set, one camera and one lighting setup make matching easy and the grade is where the effort goes. With generated footage, every clip comes from an independent sample, so exposure, contrast, colour temperature and even apparent film stock drift between takes made from the same prompt.
That inverts the workload. Expect to spend most of the time on correction, matching clip to clip, and comparatively little on the creative color grade. Three practices help.
Grade a reference frame first, then match everything else to it rather than to an abstract idea of the look. Having one approved frame turns a subjective argument into a comparison.
Ask for the look in the prompt as well, because a grade cannot invent what was not generated. Prompting muted teal shadows and warm skin tones, deep crushed blacks gets you closer to the destination and leaves the grade less distance to travel, which matters because pushing generated images hard reveals banding and compression faster than real footage does.
Finally, do the creative pass last and on the whole timeline at once, not per clip. A single grade over a matched sequence is what makes a set of independently generated shots read as one scene.
