How to make every scene in an ad share one colour theme

Last updated 2026-09-05 · 8 min read

What is the short version?

An ad assembled from separate scenes will drift in colour, and the drift is usually invisible while you are working on one scene at a time. Fixing it starts with a decision about which scene is right, not with a grade.

1. Go to Vizard Agent with the assembled ad.
2. Say which scene has the colour theme you want.
3. Say the other scenes should be matched to it.

What do you need before you start?

The cut and a decision. The decision is the harder half: "make it consistent" leaves the direction of the match open, and a reasonable reading of it will sometimes pull your favourite scene towards the one you liked least.

• The assembled ad. All scenes in place.
• Which scene is the reference. By number or by description.
• Which scenes are wrong. Or ask for a comparison first.
• Whether anything else may change. Usually nothing.
• Any brand colours that must be hit exactly.

What do you type into Vizard Agent?

Name the direction of the match. "Scenes one and two should match the theme in scenes three and four" is unambiguous where "make the colours consistent" is not, and it is the one sentence that saves a round.

Prompt

Variants worth knowing:

• "Match A to B." Says which way the grade runs.
• "Show me the comparison." Useful when you are not sure.
• "Colour only." Keeps cuts and timing out of it.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real vertical advert built from two supplied clips whose scenes did not agree with each other. The comparison comes before the grade, and it is what makes the correction arguable rather than assumed.

1. Transcribes both source videos and inspects their scene timing.
2. Inspects the scene colours and pulls representative frames.
3. Builds a scene-by-scene colour comparison you can look at.
4. Creates a graded version of the scenes that disagree.
5. Reviews the graded scenes against the later theme directly.
6. Uploads and quality-checks the revised grade.
7. Watches the revised ad for colour continuity and sync together.
8. Locates the exact logo reveal for any accompanying treatment.
9. Adds the requested accent and re-renders the updated ad.
10. Confirms the reveal still looks clean with the new sound on it.

Step three is the step that settles arguments. Scenes seen one after another feel different in ways nobody can name; the same scenes seen side by side make the disagreement obvious, and usually make it obvious which one is the odd one out as well.

Step five is the part that keeps the grade honest. Comparing a corrected scene against the reference scene, rather than against a description like "light blue and white", is the only way for Vizard Agent to know whether it actually matches rather than merely moved in the right direction.

Step one is quieter but does real work. Knowing where each scene starts and ends means the grade lands on scene boundaries rather than on a timecode somebody estimated, and a grade that changes mid-shot is far more visible than the drift it was brought in to fix.

What does the result look like?

An ad that reads as one piece. The palette holds from the first frame to the last, the cuts and the timing are exactly where they were, and only the scenes that were out of step have been touched.

The consistency is the sort of thing viewers never notice, which is how you know it worked.

When does this not work well?

Grading moves colour, it does not rebuild light. Scenes shot in genuinely different conditions — daylight against tungsten, or a bright product shot against a dim interior — can be brought closer but not made identical without changing what each one actually shows.

• Very different lighting. Matching goes only so far.
• Blown highlights. There is nothing left to recover.
• Different cameras. Skin tone in particular resists.
• Generated and filmed mixed. Their grain and colour differ.
• A deliberate shift. Sometimes a change of palette is the story.

How do you fix a result that came back wrong?

Say which scene still looks wrong, and say which scene you are comparing it against. Vizard Agent keeps the colour comparison and the grade it applied to each scene, so a note about one of them adjusts that scene alone rather than regrading the whole advert over again.

• "You matched them the wrong way." The direction reversed.
• "Scene two is too cool now." Pulled back against the reference.
• "The product colour changed." Protected and the rest regraded.
• "The skin looks odd." Graded around the faces.

How does Vizard Agent compare to doing it yourself?

By hand the usual approach is to grade each scene until it looks right on its own, which is exactly how the drift happened in the first place. Building the comparison first is a small step that nobody takes, and it is the one that makes the rest straightforward.

Common questions

Can it tell me which scene is the odd one? Yes. Ask Vizard Agent for the colour comparison first.

Do I have to pick a reference? It helps enormously. Otherwise Vizard Agent has to choose for you.

Will the cuts change? No. Vizard Agent grades without touching the edit.

Can it protect my product's colour? Yes. Name it and Vizard Agent grades around it.

What about brand colours? Give the values and Vizard Agent holds them.

Does it work across different cameras? Partly. Vizard Agent gets them closer, not identical.

Can it match to a still image instead? Yes. Supply the frame and Vizard Agent matches towards it.

Will faces be affected? Vizard Agent watches skin tone specifically and can grade around it.

Can I see before and after? Yes. Ask Vizard Agent for frames from both versions.

Does the audio change? No, unless you ask. Colour work leaves the mix alone.

What if only one shot is wrong? Then Vizard Agent grades that shot only and leaves the others alone.

Can it do this on a finished export? Yes, though grading the source gives a better result.

Will it look over-processed? Not when Vizard Agent matches to a real scene rather than to a look.

Why compare rather than just grade? Because a scene graded alone always looks right alone, and the fault only exists between scenes.
