To fix a dub line in Perso Dubbing, open the original dubbing project, compare the source and translation, edit the relevant segment, and select Apply changes. Review the updated result before downloading. Editing text alone does not apply the changes automatically.

Open the editable dubbing project
If you are viewing a Lip Dubbing result, select View Original Dubbing. The lip-dubbed result links back to the project where the script can be edited. In that editor, the source and translated text appear side by side, with a speaker assignment and start and end times for each segment.
First decide what is wrong. An incorrect product name in the source calls for a transcript correction. Accurate source text with awkward target wording calls for a translation edit. Speech that feels rushed needs a timing and phrasing review. Treat these as different checks; changing a subtitle does not by itself prove that the generated speech or lip movement is correct.
Revise one line without losing its meaning
Listen to the source, then compare the translated line. Check names, numbers, product terms and intent before shortening a sentence. Prefer a natural spoken phrase, but keep details that the viewer needs. For example, a rewrite that removes a product limitation may sound smoother while making the message inaccurate.
The captured editor shows each source line beside its translation, along with speaker and timing controls. These controls help you locate a problem; they do not replace listening to the result.
Review the neighbouring segments when adjusting start or end times. Avoid accidental overlaps, clipped speech or empty segments. A long translation may need tighter wording rather than a wider time window that intrudes on the next speaker. Keep the approved terminology consistent across the project.
Apply changes, then review the result
The editor explicitly warns that edits are not applied automatically. Select Apply changes when your corrections are ready, follow any prompts shown for your project, and wait for processing to finish. Then use the Original and Translated views to review the affected passage in context. The presence of a line playback control is not a guarantee of zero processing or a fixed regeneration time.
Check the beginning and end of the revised line, the next speaker and the surrounding scene. If you need another language, finish applying the current edits before selecting New language. During this check, that action displayed an Apply your changes first message when edits were still pending. Review each resulting language version separately.

The inspected Download menu includes a translated MP4, several WAV audio options, original and translated SRT subtitles, and XLSX scripts. Use the export that matches your destination and check the available options in your own project. Menu availability can depend on the project and plan.
Check the downloaded file with the intended video and audio track before publishing. For a finished subtitle file with a constant delay, drift or a mismatch after a cut, use our subtitle sync repair guide. For errors in the source transcript, start with the transcription review guide.
Frequently asked questions
Q. Do script edits automatically update the video?

Q. Can I edit the script from a Lip Dubbing result?
A. Use View Original Dubbing to return to the editable dubbing project. Review any later lip-dubbed version separately.
