Free AI Video Editor: The Free Edits and the Paid Ones

Quick answer: Editing a generated video here is half free. Anything that only changes words or chooses between takes costs nothing: editing the storyboard text by hand, switching to an earlier take, restoring older text, inserting or deleting a segment, downloading and sharing. Anything that makes new picture or sound is charged: a trim is 5 credits, an AI revision of the text 1 credit, lip sync 1 credit a second, an AI picture change 2 times the per-second price, and regenerating a segment its tier’s per-second price. This guide puts every edit on one table, works a three-edit example and says what to do to stay in the free column.

The credits for every paid edit are held when you press the button and come back if the edit fails. None of them has a free allowance of its own, so what you can do for free is the first six rows, plus whatever the welcome credits (50 on a new account) pay for. What each clip fix costs.

Why the line falls where it does

The free edits are the ones that do not need a model. Changing text is re-read on your side and nothing is generated; switching takes only moves a pointer; restoring text puts older text back. The paid edits all start a media process or a model call: a trim re-cuts the file exactly to the frame, a redub generates new audio, an AI picture change makes the clip again, an export joins files. That is also why the free column is the right place to do your thinking. Decide what you want in the text, where it is free to be wrong, and spend credits only when you press the button that makes something.

The one trap in the free column is the difference between changing the text and changing the video. Editing a line in the storyboard changes the plan, not the clip, so the segment keeps playing the old words until you regenerate it. Fixing one shot without redoing everything · AI edit or edit by hand.

A worked example: three problems in a 45-second episode

Take an episode of three 15-second segments on the default tier, and suppose three things need fixing. This is a different job from fixing a single clip, because here the choices interact.

ProblemCheapest fix that worksWhat it costsWhat it keeps
Segment 2: a character says “Tuesday” and the plot needs “Friday”Redub with Lip sync15 seconds at 1 credit a secondEvery frame. All the segment’s lines are voiced again, so re-read the others
Segment 2 alternative: the whole delivery is wrong, not just the wordEdit the line by hand (free), then regenerate segment 215 seconds at 10 credits a secondNothing; it is a new take, and the old one stays in the takes list
Segment 3 starts a beat earlyTrim with Keep5 creditsThe whole picture; the segment is shorter by what you cut
Segment 1 should be at nightAI visuals, the time-of-day change15 seconds at 20 credits a second on the default tier (2 times a regeneration)Acting, framing and timing; small details can differ
Put the episode togetherExport episodeThe finished length at 1 credit a secondThe trim in segment 3 makes it slightly cheaper

The pattern in the table is the useful part. A voice-only fix is a small fraction of any picture fix, a trim is a flat fee that does not grow with length, and a picture fix costs 2 times a regeneration of the same length, so of the three it is the dearest. Regenerating is worth it when the plan is wrong, because only a regeneration can change the framing, the camera or where people stand. A fix is worth it when the clip is right apart from one thing and you do not want to re-roll everything else. Lip sync or re-perform · AI visuals: what it can change.

Staying in the free column

  • Collect your notes, then regenerate once. Edit everything wrong in a segment’s text first. One regeneration pays for all of them.
  • Draft on the cheapest tier. The default draft tier is 480P and is for finding out whether a shot reads; finish the keepers on 720P or 1080P. Draft at low resolution, finish at high.
  • Use takes as a free A/B. Once a segment has two takes, switching between them is free, and the composite joins whichever is active.
  • Treat History as undo. Try an AI edit, save it, and restore the text from before it if you change your mind. The credit for a revision you discarded is not returned, but nothing else is lost.
  • Do not regenerate the whole storyboard to fix one shot. It rebuilds every segment and discards the finished videos with them, with no refund. What you lose.

What a free account can and cannot use

Credits, not plans, gate the clip fixes: trim, redub, AI visuals and enhance are priced in credits and are not on the list of paid-plan features. The paid-plan features are the ones that bring your own material in or change how the output is labelled: uploading your own pictures onto a character, place or prop, a custom visual style, the storage quota for uploads, and removing the AI badge from your videos. Subtitles are a separate gate: they need at least one purchase of credits or a plan on the account. What a paid plan changes.

If you want the same list without the free angle, video editor with AI orders the repairs from cheapest to dearest, and AI video editor explains what the editor is and is not.

FAQ

Is there a free AI video editor?

Part of editing is free: changing storyboard text, switching takes, restoring older text, adding or deleting segments, downloading and sharing. Anything that makes new picture or sound is charged in credits.

Is trimming a video free?

No. A trim is 5 credits, whatever the length, and nothing new is generated. If it fails, the credits come back.

What does an AI edit of the text cost?

1 credit for each revision that comes back and is shown to you. Failed, refused or unusable attempts cost nothing.

Can I undo an edit for free?

Yes. Every video fix is a new take and switching back is free, and the text history lets you restore earlier wording at no cost.

Do I need a paid plan to use the fixes?

No plan is needed for trim, redub, AI visuals or enhance, only credits. Uploading your own pictures, a custom style and badge removal are paid-plan features.

Are subtitles free?

They cost no credits, but they are switched on only for accounts that have bought credits or a plan at least once.

What if an edit fails?

The credits are held when you press and return if the edit fails. An AI picture change that is blocked by content review is refunded too.

What is the cheapest way to fix one wrong word?

A lip-sync redub, at 1 credit a second of the clip, keeps the picture. Editing the line by hand and regenerating the segment costs the segment’s full per-second price.
