How to Fix a Bad AI Video Shot Without Starting Over
Fix one bad AI video shot without redoing the whole video: tweak the take, rewrite what it shows, fix the line, re-cut, or trim. With costs for each fix.
To fix a bad AI video shot without starting over, first name what is wrong, then use the smallest fix that reaches it. A small visual detail (the sky, the light, a prop) can be edited in the existing take. Wrong staging or framing needs a new take from a rewritten shot description. A wrong line is fixed in the script, not the video. A shot that starts or ends in the wrong place is a cut problem, fixed by moving the boundary. A slow tail is a trim. In Paintbrush, each of these is its own control, so one bad shot costs one shot to fix. As of October 2026, a 5-second retake costs 151.5 to 172 credits and an in-place edit of the same take costs 126.
Below: how to diagnose the problem, each fix step by step, what it costs, and the one mistake that turns one bad shot into five.
What is actually wrong with the shot?
Most retakes are wasted because the fix does not touch the cause. Watch the shot twice, once for the picture and once for the sound, and put the problem in one of these groups:
| Cause | What you see | The fix |
|---|---|---|
| The take | Right shot, one detail off (weather, a color, a prop, the light) | Tweak the take |
| The description | Wrong framing, wrong people in frame, someone on the wrong side, wrong action | Rewrite what it shows, regenerate |
| The references | The face or outfit is wrong in every shot | Fix the character or outfit, then regenerate |
| The setting | The room is wrong in every shot of a place | Fix the setting, or add a new setting for that part of the place |
| The script | A line is wrong, badly read, or badly timed | Edit the line, generate the audio again |
| The cut | The shot starts too early or ends too late, or two moments share one shot | Move the boundary, split or merge |
| The edit | A slow tail or a dead second | Trim or cut it in the timeline |
Retrying the same shot unchanged is a coin flip. It sometimes works for a one-off glitch, like a hand that melts for a frame, but if the problem comes from the description or the references, the next take will make the same mistake.
How do you fix a small detail without a new take?
Edit the take you have. In Paintbrush, open the shot and type into Tweak this take, for example "make the sky overcast" or "her mug is red". The edit is a video-to-video pass (Kling O3) over the current clip, so the framing, the motion, the clip length and the timing of the lines stay as they were, and the voice stays with the picture.
A tweak costs 25.2 credits per second of the clip as of October 2026: 126 credits for a 5-second shot. Use it for:
- Color, weather and time-of-day changes.
- A prop that is the wrong color or shape.
- Small changes to how something looks, where the staging is already right.
Do not use it to move people, change the camera angle or add someone to the frame. A video edit keeps the motion it was given, so a staging problem survives the edit. That needs a new take.
How do you fix wrong staging or framing?
Rewrite the shot's description and generate it again. In Paintbrush, the scene dialog has a What it shows field. It holds only what is seen: the framing, who is in frame and where, the action, what is behind them, the time of day and the light. Characters and the setting are named with @mentions, so their reference images go with every take. The lines are not in it; they come from the chapter audio.
Fix the description like a camera note, not a mood:
Before: @Mara and @Theo talk in the booth, tense.
After: Medium shot from the aisle. @Mara sits screen-left by the window, facing right; @Theo sits screen-right, facing her, his hands flat on the table. Rain on the window behind @Mara. Night, warm light from the lamp above the table.
Then click Regenerate. The button shows the credits for that shot, including a keyframe if it needs one. As of October 2026, a 5-second shot with someone speaking on camera costs 151.5 credits, a silent or narrated one 164, and a new angle in the same room adds an 8-credit keyframe. Our AI video prompt guide covers what to put in a description and what to leave out.
If you work with the creation agent, say it in plain words: "redo shot 4 with Mara facing the window" or "make the sky overcast in shot 6". It rewrites the shot or edits the take, and shows the shots and the credit estimate for approval before anything is spent.
Why do the shots after a fixed shot need a look?
This is the mistake that turns one bad shot into five. Paintbrush generates a chapter's shots in order, and each shot is staged from the actual ending of an earlier one: a continuous shot opens on its last frame, and a new angle is first drawn as a keyframe from it. If you fix shot 3, the shots staged from it were drawn from its old ending. A coffee cup that moved, a character who now stands instead of sits, a light that changed: those differences show at the next cut.
So after a retake, watch the shots that follow it. If they no longer match, right-click each one and choose Clear video, then use Generate shots in order under the chapter to make them again from the new ending. Fix shots front to back, and do not build later shots on a broken one. Scene chaining explains how shots are staged from each other.
How do you fix a wrong line or a bad read?
Fix the script, not the video. Open the chapter, change the line or its delivery tag (for example [quietly, holding back tears]), and generate the chapter audio again. Only new and changed lines are performed; the unchanged lines keep their takes and pauses. Speech costs 8 credits per 1,000 characters, so a 100-character line is under a credit.
When the new audio is ready, every shot is re-sliced. A shot whose lines are timed as before keeps its video. A shot whose slice changed is marked out of date and needs a new take. That is why the cheapest time to fix dialogue is before generating video. See how to write dialogue for AI video for tags, pauses and silent beats.
How do you fix where a shot starts or ends?
That is the cut. Open the chapter: its audio shows each shot's stretch on the chapter timeline. You can:
- Drag a boundary between two shots. It lands in the nearest silence, never inside a line.
- Split a shot at a line or beat, so a reaction or a gesture gets its own shot. The new shot starts with the same description and no video; rewrite it before generating.
- Merge a shot with the next one when two shots only repeat each other. Deleting a shot does the same: its stretch joins a neighbour.
Each shot's length comes from its slice of the audio, rounded up to a whole-second clip of 4 to 30 seconds and trimmed to fit. A re-cut shot needs a new take because its slice changed.
How do you fix a slow ending or a dead second?
Trim it in the timeline. In the project preview, drag across the track to highlight a range, then cut, delete or speed it up (1.25 to 4 times). Timeline edits change playback and export only; they never change the shot itself, so you can undo them freely. Trimming is free, and it is often the right fix for a shot that is fine except for its last second.
What if the problem is in every shot?
Then the shot is not the problem. A face that drifts in every shot, or a character who wears the wrong clothes, comes from the reference images. Regenerate the character with a change request (36 credits; Keep current look keeps small edits close to the approved look), or give them an outfit for that chapter. A room that keeps changing usually means the shots look at a part of the place the setting image does not show. See how to change a character's outfit and how to keep backgrounds consistent.
Fix the reference first, then regenerate the shots that use it, in order. Regenerating shots against a bad reference spends a shot's price to get the same mistake again.
What does fixing a shot cost?
As of October 2026, in every style:
| Fix | Cost for a 5-second shot |
|---|---|
| Trim or cut in the timeline | Free |
| Move a boundary, split or merge | Free (the changed shots then need new takes) |
| Change a 100-character line | 0.8 credits of speech, plus new takes for shots whose slice changed |
| Tweak the take | 126 credits |
| New take, on-camera dialogue | 151.5 credits (159.5 with a keyframe) |
| New take, silent or narrated | 164 credits (172 with a keyframe) |
| New character or outfit | 36 credits, plus new takes of the shots that use it |
Failed generations are refunded automatically, including every charge tied to the job. Retakes of shots that succeeded are charged again, so plan 1.5 to 2 times your first-pass budget for a finished video. The full math is in what AI video costs per minute.
How do you get fewer bad shots in the first place?
- Approve assets before any video. A character costs 36 credits to redo; after the shots exist, it costs every shot it is in.
- Lock the script first. Read the lines aloud before generating video.
- One job per shot. An entrance, a reaction, a turning line. Shots that try to do three things fail at one of them.
- Review each shot before the next. Generate a chapter, watch it, fix front to back.
- Keep the camera on one side. See multiple characters in one scene for staging that survives cuts.
FAQ
Can I edit an AI video clip instead of regenerating it?
Yes, for small visual changes. In Paintbrush, Tweak this take runs a video-to-video edit on the current clip and keeps its length, timing and voice, at 25.2 credits per second (126 for 5 seconds) as of October 2026. Staging and framing changes need a new take.
Do I have to regenerate the whole video to fix one shot?
No. Each shot is generated and fixed on its own. Only the shots staged from a fixed shot may need new takes, and only if they no longer match its new ending.
Why does the same mistake come back when I regenerate?
Because the cause is in the description or the references, not in luck. Rewrite what the shot shows, or fix the character or setting, before generating again.
Are failed generations charged?
No. Failed generations are refunded automatically. Retakes of shots that succeeded are charged.
