Revise the Whole Episode: One Request, Every Segment

Quick answer: Write one request — “make every line colder and shorter”, “add rain sound under the scene” — and press Apply to the whole episode… in the AI edit panel. Pick the segments, press Start, and the same request runs on each of them. The results come back as a list: open a row to see the change, then save them all at once or one by one. Nothing reaches your script until you save. Segments that need no change, and requests the storyboard text cannot fulfil, are not charged — so the number on the button is the most a run can cost.

This is the same engine as AI edit on a single segment, run across many segments at once: same request box, same checks, same price per segment, same History. What changes is how many segments ride on one request, and how you review the outcome. Reach for the whole-episode run when the note applies from the first segment to the last — a way of speaking, a word someone keeps using, a sound that should sit under a whole scene, a pace that drags. Reach for single-segment AI edit when one segment is off and the rest are fine.

What it does

You give it one request. It revises each selected segment against that segment’s own text — the same request, applied wherever you ticked it. Every segment comes back as one of three things: revised, needing no change, or failed; the list tells you which, and you decide what to keep. It never rewrites the episode as one block, and it never touches a segment you did not pick.

Where to find it

The whole-episode button only appears for revising. If the segment on screen is blank, or written as plain prose instead of shots, the panel is in AI write mode and there is no whole-episode button — writing a segment from nothing is a one-segment job. To revise the episode instead, open any segment that already has shots.

Step by step

  1. Open the episode in the editor. Project → step 3 → Start Editing on the episode’s card.
  2. Open AI edit on any segment’s card and write the request. The small chips above the box (lines, action, mood, time and weather, camera, keep someone out, voice-over, another scene) are sentence starters, not a menu.
  3. Press Apply to the whole episode…. A dialog opens with your request quoted at the top.
  4. Pick the segments. Everything it can revise is listed and ticked to begin with; the count sits above the list, with Select all and Clear. Untick whatever should stay as it is. The Start button carries Up to ✦ N — the most this run can cost.
  5. Press Start. A progress line counts the segments as they are revised (Revising 3 of 12…), and each row shows its state as it arrives: waiting, revising, Changes: 2, No change needed, Couldn’t revise.
  6. Stop whenever you like. The segments already revised stay in the list; the ones that had not started are dropped, and nothing is charged for them.
  7. Review each row. View opens the line-by-line diff — removed lines struck through, added lines in green. If the request changed the segment’s shots or seconds, the row also says the length is going from Xs to Ys and whether regenerating that segment’s video costs more than before.
  8. Save what you keep. Save all (N) writes every revised segment into the script as a normal edit, or press Save on a single row to keep only that one. Discard results throws the unsaved ones away — and warns that the credits already charged for them are not refunded. Close leaves them for later.

Saving changes the storyboard text only. The segment still plays the old take until you regenerate it — the same as any edit to the text. The summary line under the list keeps the count honest as you go: revised, no change needed, could not revise, and what the run has been charged.

If you refresh, close the page, or come back later

Revised results that are not saved yet are kept on this device — this browser, on this computer — until you save or discard them, and for a day. Reopen any segment’s AI edit panel in that episode and there is a line: You have unsaved results from an earlier run. Press View to open the list again and save from there. The panel says it plainly: results are kept on this device until you save or discard them.

Each result is tied to the exact text it was made from. If a segment’s text changed in the meantime — a hand edit, a restored version — that segment’s old result is dropped from the list, so an earlier revision never lands on newer text. If every revised segment has changed, there is nothing left to resume. Another browser or another computer will not see the results at all.

One run at a time: starting a new run replaces the list. Save or discard what you want to keep before running another request.

What it can change

Whatever single-segment AI edit can do, it can do to each picked segment:

Examples that work

RequestWhat comes back
“Make every line colder and shorter.”Each picked segment comes back with tighter, colder lines; shot counts and timing stay as they were.
“Add rain sound under the whole scene.”Each segment’s sound line carries the rain; regenerate a segment and the rain is in the clip’s audio.
“Split the argument into more shots — closer angles.”Shots are added inside the segments you picked; each row shows the segment’s new length, and whether its regeneration price changed.

Examples that come back as “No change needed”

RequestWhy, and where it does live
“Give the villain a black coat.”A character’s face, hair, build and outfit come from the character image and its states, not from the storyboard text. The note points at the character; change the image or add a state.
“Use a different voice for her.”Voices are picked on the character, not written in the segment.
“Turn the background music off.”Music is not part of the storyboard text; the Music switch by the player turns it off.

Two more that read the same way: the spoken language of a project is a project setting, not a line in a segment; and anything that appeared in a finished clip that the storyboard never wrote — an extra passer-by, a stray line — came out of generation, so a revision has nothing to remove. Regenerating that segment is what usually clears it.

What it costs

Every segment that comes back revised is charged once, at the same per-segment price as a single AI edit (the price is on the pricing page). The number on the Start button — Up to ✦ N — is the ceiling for the segments you ticked, not a bill: segments that need no change are free, failed revisions cost nothing, and a segment is charged at most once per run.

Two things stop a run part-way. In both cases everything already revised stays in the list and can still be saved, and the segments that never ran are not charged:

Stopping the run yourself, discarding results, or leaving them unsaved does not refund revisions that were already charged — the charge happens when a segment is revised, not when it is saved.

When a row does not come back changed

No change needed means the segment was read and left as it was. The note under the row usually says why: either there was nothing worth changing, or the request is aimed at something the text does not hold (the table above). Nothing is charged.

Couldn’t revise means the revision did not come home: a hiccup on the way, a reply that could not be used, or a request that would push this segment past what it can hold. The reason sits under the row, and nothing is charged. To retry, save or discard the results you have, then run the request again over just those segments.

Writing a request that lands

Whole episode, or one segment?

Same engine, same price per segment either way. The difference is how many segments ride on one request, and how you review them.

FAQ

Does the whole-episode run rewrite my script at once?

No. Each segment is revised on its own text and listed for review; only the rows you save are written into the script.

Which segments appear in the list?

The ones whose text is a storyboard with recognizable shots. Blank segments and segments written as plain prose are left out; open one of those and use AI write.

Can I leave some segments alone?

Yes. Every segment it can revise starts ticked; untick any of them, or press Clear and pick. Segments you leave out are not revised and not charged.

Am I charged for segments that need no change?

No. Only segments that come back revised are charged, and a failed revision costs nothing. The number on the button is the maximum for the segments you picked, so a run usually costs less.

What happens if I refresh or close the page mid-run?

Results that were already revised are kept on this device for a day. Reopen the AI edit panel on any segment of the episode and a line offers to open them. Segments whose text changed in the meantime are dropped from the list.

Can I stop a run?

Yes, press Stop. The segments already revised stay in the list and can be saved; the ones that had not started are dropped and are not charged.

Can it add or remove shots, or change a segment’s seconds?

Yes, within what a segment can hold. When a request changes the timing, the row shows the length before and after, and whether regenerating that segment’s video costs more.

Does saving regenerate the videos?

No. Saving changes the storyboard text only. Regenerate a segment when you want a clip made from the new text.

Can I undo a saved revision?

Yes, one segment at a time: open that segment’s History and restore the version from before the change.

Does it work on a phone?

Yes. The same dialog opens as a sheet from the AI edit button on the Script tab.
