How to fill the gaps in your own footage with generated shots that match

Last updated 2026-08-18 · 6 min read

What is the short version?

You filmed most of a video. There are two or three shots you did not get, and going back for them means setting up again for thirty seconds of screen time. That gap is why half-finished videos stay half-finished.

1. Go to Vizard Agent and upload everything you filmed.
2. Say what the video is meant to show and which shots are missing.
3. Say the pacing and the look.

What do you need before you start?

Your footage and a sense of the missing piece. Vizard Agent works out the look from what you already shot, so the generated shots inherit your lighting and framing rather than arriving from somewhere else, and what it needs from you is what the video is supposed to say.

• Everything you filmed. Including the takes you think are unusable. They set the style.
• What the video is about. The story it tells, not just the shots in it.
• What is missing. "I never got a shot of the screen", "there is no closing shot".
• The pacing. Quick cuts and a modern feel, or slow and observational.
• The feed. Vertical for social, wide if it is going somewhere else.

What do you type into Vizard Agent?

Describe the finished video, not the gap. Vizard Agent watches what you uploaded and works out for itself which beats are missing, so a description of the whole piece gets you a better result than a shot list of what to generate.

Prompt

Variants worth knowing:

• Generated shots only where needed. Say so if you want your own footage to dominate.
• Match a previous video. Keep them in one project and the look carries across.
• A wide and a vertical cut. Ask for both; the second is re-framed rather than cropped.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real gap-filling job. Almost half of the run is spent looking at the footage you already have, scene by scene, because your own frames are the thing every generated shot has to match.

1. Checks the project's past files and deliveries.
2. Loads the vlog playbook, lists the tools and probes the footage.
3. Downloads it, extracts frames and measures the audio.
4. Builds a contact sheet of every frame and transcribes and shot-logs the footage.
5. Looks through the contact sheet, then at each scene individually — the opening, the desk, the close-ups, the reaction, the writing.
6. Measures the audio per scene and detects the cuts.
7. Extracts style references out of your own frames and searches for music and stock.
8. Generates the missing shots alongside the music and a stock timeline.
9. Probes the generated clips, extracts review frames from each, and checks every one against your footage for likeness before anything is cut together.

Step 9 is what separates this from bolting generated footage onto a real video. Vizard Agent looked at each generated shot next to the real ones and judged whether it belonged, rather than trusting that a good prompt produced a matching result.

What does the result look like?

From the run this page is written from, probed on the delivered file: 1080x1920, H.264, 30fps, 25.74 seconds, AAC audio. Vertical, twenty-six seconds, your own scenes cut together with generated shots filling the beats you never filmed, scored and paced as one piece.

Vizard Agent uses your footage as the spine and generates only what is missing. The proportion matters: a video that is mostly yours with two generated shots reads as complete, and the reverse reads as generated.

Twenty-six seconds across your scenes and a handful of generated ones is roughly the balance that works. Vizard Agent keeps the generated shots short and lets your own footage hold the longer beats.

When does this not work well?

Generated shots inherit their believability from how close they sit to real ones. Vizard Agent matches the style from your own frames and reviews every result, and the join is still the thing a careful viewer notices first.

• Your face in a generated shot is the hard case. Hands, backs and objects are far safer than a recognisable person.
• The ratio decides the effect. A few generated shots inside real footage works; mostly generated does not.
• Lighting is the tell. If your footage is lit unusually, the generated shots will need more correcting.
• It cannot generate the thing that actually happened. A missing shot of a real event is missing, and a plausible substitute is not the same.
• Say so if it could be mistaken for real. A video mixing filmed and generated shots is worth being honest about, and Vizard Agent cannot make that call for you.

How do you fix a result that came back wrong?

Name the shot that is wrong. Vizard Agent keeps your original footage, the style references it pulled out of your frames and every generated clip as separate pieces, so replacing one generated shot leaves your own scenes, the music and the pacing exactly as they were.

• "That shot does not match the rest." Regenerated against the same style references.
• "Use more of my own footage." A re-cut weighted towards what you filmed.
• "The join is obvious." A different cut point or a transition over it.

How does Vizard Agent compare to doing it yourself?

By hand this is either going back out to film the missing shots, which is the honest answer and almost never actually happens, or dropping in stock footage that was clearly shot by somebody else in a different room on a different day.

Common questions

How much can it generate? As much as you ask, and the result is strongest when your own footage still dominates.

Will the generated shots match my lighting? Vizard Agent pulls style references from your own frames, which is what keeps them close.

Can it generate a shot with me in it? It can, and that is the hardest case. Hands, over-the-shoulder and object shots are far more reliable.

Does it use my audio? Yes. Your recorded sound carries the video and the music sits underneath.

Can it match a video I made before? Yes, if it is in the same project. Vizard Agent checks your past deliveries first.

Should I say the video contains generated shots? If it could be taken for entirely filmed footage, yes. Vizard Agent makes the join close, and the disclosure is yours to make.

Does it work with very little footage? It works better with more. Vizard Agent needs real frames to pull the style from.
