“Your Edit Could Not Be Synced”: What It Means and How to Fix It

Quick answer: When you read and edit a storyboard in a language other than the project’s working language, every save is translated back into the production copy — the version video generation uses. A status line above the segment tells you how that went. Your edit could not be synced to the production copy. The previous version is still used for generation. means the translation back failed, and the line after it says why: most often an @ name was changed, the shot count or seconds changed, or a line was separated from its voice tag. Fix that in your text and save again, or press Restore machine translation to throw your edit away and start again from the version generation uses.

Who sees these messages

Only people who read a storyboard in a different language from the one the project works in — for example, a Japanese interface on an English project. The storyboard you read and edit is a translation; the one video generation reads stays in the project’s working language. Every time you save, your change is translated back. With an English interface on an English project, and on the Chinese site, there is nothing to sync and none of these lines appear. Working in your own language · Interface, script and dialogue language.

We couldn’t translate it into the production language, so your text is used as written for now.	Your text went into the production copy as you wrote it.	—

The eight reasons, and what to do about each

Reason shown	What went wrong	What to do
An @ reference (the name after @) was changed or removed — keep those names exactly as they are.	A character, scene or prop chip was edited, retyped or deleted, so it no longer matches the project.	Put the chip back from the @ menu instead of typing the name; save again.
The number of shots or their seconds changed — edit the text inside a shot, not the shot headers.	A shot marker or its seconds was added, removed or changed in your language.	Put the shot markers and seconds back as they were and edit only the words inside the shots; or press Restore machine translation and redo the edit that way.
A dialogue line or its voice tag changed — keep each line together with its voice tag.	A line and the voice tag after it were split, or a tag was removed.	Keep every line followed by its voice tag; change only the words of the line.
The translation came back malformed. Please try again.	A one-off translation error.	Save again.
Translation is busy right now; it will retry automatically.	The translation service was busy.	Nothing; it retries on its own.
We couldn’t translate it into the production language, so your text is used as written for now.	Usually a segment you inserted and wrote yourself: it could not be translated back, so your own words were kept.	Nothing needed; it is translated again automatically when it can be. Check the segment before generating.
Syncing took too long. Save again to retry.	A timeout.	Save again.
Something went wrong. Save again to retry.	Any other error.	Save again; if it keeps happening, restore and redo the edit.

What Restore machine translation does

Restore machine translation deletes the translation you edited for this segment and has the segment translated again, fresh, from the production copy — the version that video generation is still using. Your edit in your language is gone after that. Retry on a Not translated line does the same thing: it translates the segment again.

So before you press it, copy the change you wanted (the words, not the chips), restore, then make the change again carefully — inside the shots, keeping chips and voice tags. If the edit was small, fixing the cause and saving again keeps it without restoring.

Editing in your language without breaking sync

Insert names with the @ menu. A typed name is not a chip, and changing a chip’s text breaks the reference. The @ menu.
Leave the labels alone. Shot markers, header fields and voice tags are shown as pills in edit mode; type between them, not inside them. Why storyboard labels turn into pills.
Leave shot markers and seconds as they are. Adding a shot, removing one or changing seconds in the translated text is the change that most often fails to sync; the reason line itself says to edit the text inside a shot, not the shot headers.
Copy and paste inside the editor, not from another document, so chips survive. Copy and paste without losing links.
Wait for the line to clear before you generate. A generation started during syncing waits for it.

A storyboard segment: location, time and weather fields, then numbered shots with durations, asset chips and spoken lines — A storyboard segment: the header fields, then numbered shots with their seconds, @ chips for who is in frame, the lines and the sound.

Before you generate: which text will be used

If the segment shows Your edit could not be synced…, generating now makes the video from the text before your edit. Fix or restore first, wait until the line clears, then generate. If it shows the used as written for now line, the video is made from your own words as typed. The five wait messages · Storyboard text history.

You did	Likely reason	Fix
Retyped a character’s name	An @ reference was changed	Insert it from the @ menu
Added or deleted a shot, or changed seconds	The number of shots or their seconds changed	Put the shots back; edit only inside them
Moved a line away from its voice tag	A dialogue line or its voice tag changed	Keep each line with its tag
Nothing unusual	Busy, timeout or malformed	Save again, or wait

FAQ

What is the production copy?

The version of the storyboard video generation reads, kept in the project's working language. The storyboard you read in your own language is translated from it, and your saves are translated back into it.

Is my edit lost when sync fails?

Not at once: your text stays on screen. But video generation keeps using the earlier version until the edit syncs. Fix the reason and save again, or restore and redo the edit.

What does Restore machine translation do?

It deletes your edited translation of this segment and translates the segment again from the version generation uses. Your edit is gone afterwards, so copy the words you wanted first.

Why does changing seconds fail?

Shot markers and seconds have to match between the two versions exactly, so a change to them in the translated text does not sync. Edit only the words inside the shots.

Why does it say an @ reference was changed when I only fixed a typo?

The typo was probably inside a chip, or the name was retyped as plain text. Put the chip back from the @ menu.

Can I generate while it is syncing?

You can press generate; the generation waits until the edit has synced, then starts.

Do I see these messages on the Chinese site?

No. They only appear when you edit a storyboard in a language different from the project's working language.

Does the dialogue language change when I edit in my language?

No. The language the characters speak is a project setting. Editing in your own language changes only which language you read and write the storyboard in.

Edit in your language, keep the structure

Change the words inside the shots, keep the chips, markers and voice tags, and the edit syncs on the first try.
