Storyboard Checks: Two Drafts, What Gets Saved, and the Rare Case Where the Task Fails

Quick answer: Every storyboard draft is checked before it is saved: the segment structure is complete, the text is in the project’s working language, every spoken line from the outline is present, shot timings add up. A draft with problems gets one rewrite with the list of problems, and the better of the two drafts is saved — so a storyboard can arrive with a small problem left in it, which you fix in the editor. The task only fails when neither draft comes back as a usable storyboard at all: nothing is saved, you are not charged, and the credits stay held until support reviews the task and returns them.

After a storyboard is saved, read it once against the outline: a missing line or a shot in the wrong language is the kind of leftover the second draft did not fix.

What the two drafts are

The model writes a draft; the site checks it; if there are problems, they go back with the draft for one rewrite; the rewrite is checked too. The site keeps whichever draft has fewer serious problems. There is no third attempt. How a storyboard is generated: Generate the Storyboard for an Episode.

The episode timeline: every segment as a card with its thumbnail and duration — A storyboard draft is checked before it is saved; a draft with problems gets one rewrite, and the better draft is kept.

What is checked

Structure: every segment has its header and its shots. Language: the text is in the working language; a translated interface does not change this. Dialogue: every line from the episode outline appears, on a shot, with its speaker. Timing: shot seconds are within range for the segment length. Output cut off (the model stopped mid-text) counts against the draft: Output Was Cut Off.

When the task fails

Only when neither draft is a usable storyboard — both came back unreadable or cut off. Then nothing is saved for the episode and you are not charged; the storyboard credits are held rather than returned on the spot, because the site cannot always tell how much of the work the service already did. Support reviews held tasks and returns the credits; you can also write to support from Help with the episode name.

When a saved storyboard has a leftover problem

Open the segment and fix the text: add the missing line to the shot where it belongs, rewrite a shot that slipped into another language, adjust a shot’s seconds. Editing is free. Regenerate the whole storyboard only if most of it is off.

If it keeps going wrong

Too much in one episode: a very long outline with many scenes and lines is more than one storyboard lays out consistently; shorten or split it. Dialogue language: outline lines in one language while the project expects another make the model slip; the dialogue language cannot be changed after the script is read, so for another language start a new project with the same script. Odd structure: an outline that is mostly narration gives the model nothing to shoot; rewrite it as scenes with things happening. Transient: the model service was unstable; retry a few minutes later.

What you see	Likely cause	Do
A line from the outline is missing	Very long outline	Add it in the editor; trim the outline next time
A shot in the wrong language	Outline lines in another language	Rewrite the shot; fix the outline’s lines
Storyboard task failed	Neither draft was usable	Retry; credits held until support returns them
Output cut off	Too much text	Split the episode

FAQ

Was I charged for a failed storyboard?

No. A failed storyboard task is not charged; its credits are held until support reviews and releases them.

Why not try a third time automatically?

Two drafts almost always produce a usable storyboard; when they do not, the material usually needs a change first.

Does a failed storyboard delete my clips?

No. Existing segments and clips stay until a storyboard succeeds and replaces them.

How long can an episode outline be?

There is no fixed limit here; very long outlines are the most common reason for leftover problems.

Can I write the storyboard by hand instead?

Yes, segments can be inserted and edited manually.

Read the saved storyboard once

The check catches most problems; a quick read catches the rest.
