Video Editor With AI: Fixes, Prices and Limits

Quick answer: In SceneMixer the AI does not cut footage on a timeline. It fixes a finished clip in a handful of ways, and each has a price you can set beside the price of regenerating the segment. Trim cuts the start, the end or a moment for a flat fee. AI visuals changes one thing from a menu of eight at 2 times the per-second generation price. Redub changes a line or a voice, by lip sync at 1 credit a second or by re-performing at the AI visuals price. Enhance raises the resolution one step. And AI edit rewrites the storyboard text from one sentence for 1 credit a revision. This guide puts them in the order to try them, cheapest first, and says what none of them can change.

AI visuals, or redub: re-performOne thing in the picture, or a line acted again (re-perform: clips of 15 seconds or less)2 times the tier’s per-second price, per second of clipKept apart from the one change; small details can differ
EnhanceRight, but softPer second, by option and target resolutionSame take, one resolution step up

Every fix is saved as a new version of the segment and the clip you started from is kept, so switching back is free. None of these has a free allowance, but the credits are held when you press and come back if the fix fails. Edit this clip: the four tabs · What each fix costs.

A worked example: one 10-second clip that is nearly right

Take a 10-second clip made on the default tier. What each way of fixing it costs, before any rounding:

WayPriceCompared with regenerating
Regenerate the segment10 seconds at 10 credits a secondThe baseline
AI visuals (one change)10 seconds at 20 credits a second2 times the baseline
Re-performThe same as AI visuals2 times the baseline
Lip sync10 seconds at 1 credit a secondA small fraction of it
Trim5 creditsA small fraction of it

The pattern holds on every tier: a picture fix costs 2 times a regeneration of the same length, and a voice-only fix costs a small fraction of either. So AI visuals is worth it when the clip is right apart from one thing and a regeneration would roll the dice on everything else: the acting, the framing, the timing you already like. Regenerating is cheaper when the storyboard is wrong, or when the clip was made on an expensive tier and a cheaper one would do.

What the AI decides, and what you decide

ToolYou provideThe AI decidesThe check
AI visualsOne change from a fixed menu, its option, and who it applies toHow the clip looks with only that changedNo free-text box, on purpose: these are the changes that come out reliably
AI edit (text)A request in your own words, up to 500 charactersWhich words, shots and seconds changeShots, seconds, names and language must match, or the revision is dropped at no charge; you press Save
RedubThe new words and the voice for each lineNothing about the pictureLines are checked to fit the clip before you are charged
TrimWhere the clip starts and endsNothing; no AICut at the exact frame, picture and sound together

The eight picture changes are clothes colour, time of day, weather, background people, lights, a scar, an expression, and swapping one character for another. On a 30-second clip you choose the first or second half, and only that half is edited and charged.

What none of the fixes can change

All of them start from the clip you have, so they keep how it was shot. They cannot change the framing (close-up versus wide), the camera angle, where people stand or which way they face, and they cannot remove a person who should not be there or fix words that appeared in the picture. Those come from the storyboard: edit the shot text and generate the segment again. When a shot comes out wrong.

And there is no timeline for colour grading, titles over footage, mixing with real footage or frame-accurate cuts between clips. For those, download the original-quality file and use an editor made for that. AI video editor covers where the line between the two sits.

The one button that costs the most

Regenerating a segment is safe. Regenerating an episode’s storyboard is not: it rebuilds every segment’s text and discards the finished videos with them, with no refund. If the text is the problem, fix it with AI edit or by hand, which keeps the videos, and use History to go back if you regret a change. Regenerate a storyboard: what you lose · Text history.

FAQ

Can AI edit a video after it is made?

Yes, in set ways: trim it, change one thing in the picture from a menu of eight, change a line or voice, or raise the resolution one step. Each saves a new version and keeps the clip you started from.

Is there an AI video editor with a timeline?

No. The timeline lists the segments of an episode. Changes are made to one segment at a time by editing its text or using the fixes. For frame-accurate edits, export the file.

What does an AI fix cost compared with regenerating?

A picture fix is 2 times the per-second price of regenerating the same length. A voice-only fix and a trim cost a small fraction of either.

Can I type exactly what I want changed in the picture?

No. AI visuals offers eight changes only. Anything else is a storyboard edit and a regeneration.

What if the fix fails?

The credits are held when you press and come back if it fails. A fix blocked by content review is refunded too.

Do I pay for an AI edit I discard?

Yes, 1 credit: the revision was made and shown to you. Failed, refused or unusable attempts cost nothing.

Can I undo a fix?

Yes. Every fix is a new version; switching back to the one you started from is free. Text changes can be restored from History.

Can it change the camera angle?

Not on a finished clip. Change the camera in the shot text, by hand or with AI edit, then regenerate the segment.
