How to combine two existing promos into one film that matches both

Last updated 2026-08-17 · 6 min read

What is the short version?

You have two promos for two parts of the same organisation. A third film that covers both has to look like it came from the same place as the first two — which means the reference is your own back catalogue, not a style description.

1. Go to Vizard Agent and say you want one film covering both strands.
2. Make sure your earlier promos are in the same project.
3. Say the length, the shape and what the combined message is.

What do you need before you start?

The earlier films and the joint message. Vizard Agent studies what you have already published and matches it, so the thing it needs from you is the argument for combining them — the sentence that makes one film out of two.

• Your previous promos. In the same project. This is what the new film matches.
• The combined message. "One church, one mission" rather than two summaries stitched together.
• Any logos or wordmarks. Vizard Agent will find them in your past uploads if they are there.
• The length. Around a minute for a film shown to a congregation or a meeting.
• The shape. Wide for a screen; ask for a vertical cut as well if it is going to a feed.

What do you type into Vizard Agent?

Say what the two strands are and why they belong in one film. Vizard Agent finds and studies your previous work itself, so the useful part of the brief is the message rather than the style — the style is already published.

Prompt

Variants worth knowing:

• Keep each strand recognisable. Say so; a fully blended film can lose both identities.
• Your own photographs. Anything real of your actual members raises the whole film.
• A shorter cut. Ask for both lengths; the second comes from the same generated scenes.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real combined promo. The first third is spent looking backwards — at your two finished films — because that is where the answer to "what should this look like" already exists.

1. Opens the images you attached and checks the project history.
2. Downloads your last two finished films to study their style.
3. Loads the generated-film playbook rather than improvising a structure.
4. Extracts frame grids from both reference videos and looks at each in turn.
5. Pulls the logo files and the rest of your reference images from past uploads and reviews them all at once.
6. Generates a look and wardrobe sheet, the narration, the music and the wordmark in one pass.
7. Fixes the wordmark job and listens back to the narration before going further.
8. Prepares a shoot script and generates the scenes for each strand, then the united ones.
9. Builds contact sheets of all eighteen clips and reviews each group against the references.

Step 6 is the one that makes eighteen scenes hold together. A look and wardrobe sheet, made before any scene is generated, is what stops the clothing, the setting and the light changing between shots that are meant to be the same day.

What does the result look like?

From the run this page is written from, probed on the delivered file: 1920x1080, H.264, 30fps, 58.5 seconds, AAC audio. Wide, just under a minute, eighteen generated scenes covering both strands and their shared ending, narrated and scored, matching the two films that came before it.

Vizard Agent reviewed the clips in groups as contact sheets rather than one at a time, which is how a set of eighteen gets judged as a film rather than as eighteen separate generations.

Just under a minute across eighteen scenes means roughly three seconds each. Vizard Agent cuts at that pace deliberately: it keeps both strands moving and stops any single generated shot from being examined too closely.

It is not instant, and this category was not separately measured. Comparable work runs a median of 28 to 38 minutes end to end. Across all projects the median cost by tier is Flash 47, Pro 55, Max 242, Ultra 263 credits.

When does this not work well?

Matching your own back catalogue is only as good as the catalogue. Vizard Agent studies the frames of what you published before and builds to them, and if those films were made in a hurry the new one inherits their compromises.

• It matches what exists, including its faults. Say if you want the new film to raise the bar rather than match it.
• Combining can flatten both identities. Two strands blended too smoothly stop being two things.
• Generated people are not your congregation. Photographs of real members carry more than any generated scene.
• Eighteen scenes is a substantial generation. Cost scales with the number of shots, not the runtime.
• A combined film needs a combined message. Two summaries stitched together is not one film, and Vizard Agent will build whichever you brief.
• Two audiences in one film is hard. If the strands speak to different people, two films may be the honest answer.

How do you fix a result that came back wrong?

Name the scene or the strand. Vizard Agent keeps the look sheet, every generated clip, the narration and the wordmark separately, so re-shooting one scene or rebalancing the two strands is a change to part of the film rather than a rebuild.

• "Give the second strand more time." A re-balance against the same scenes.
• "Scene nine does not match the look sheet." Regenerated against it.
• "Use the wordmark from the older film." Recomposited from your uploads.

How does Vizard Agent compare to doing it yourself?

By hand this is watching your two old films, writing down what they look like, briefing a production company on it, and hoping the third one feels like a set with the first two rather than a departure.

Common questions

Does it need my old films? Not strictly, and they make the difference. Keep them in the same project and Vizard Agent studies them first.

Will the scenes look consistent? Yes. Vizard Agent builds a look and wardrobe sheet before generating anything and checks the clips against it.

Can it find our logo? Yes, if it was uploaded before. Vizard Agent looks through your past project files.

Can I use real photographs of our members? Yes, and it is much stronger. Upload them and Vizard Agent works them in.

How long should a combined promo be? Around a minute. Two strands and a shared ending fit comfortably in that.

Can I get a vertical cut too? Yes. Vizard Agent re-frames the same generated scenes for the new shape rather than cropping the wide film.

Does it add music? Yes. Vizard Agent searches and mixes a bed under the narration, matched to the earlier films' register.
