Change a Line of Dialogue After the Video Is Made

What the panel shows

One row per line of dialogue in the segment, in order. Each row has the speaker’s name, a voice pill (the voice that line will use), a play button to listen to that voice, and a text box with the line itself. Only lines written as dialogue in the storyboard are listed; if the segment has none, the tab says This segment has no dialogue.

Change what is said

1. Select the segment and open Edit this clip → Redub.
2. Edit the text of the lines you want to change. Leave the others as they are.
3. Check the voice pill on each row; click it to pick a different voice from the library. Changing a voice.
4. Choose Lip sync or Re-perform; each shows its own price.
5. Press Redub into a new version. The panel shows Redubbing… until it is done.

If you empty a text box, the line is not deleted: when you click away the original words come back, and that line is spoken as before, only in the voice you picked. Lines cannot contain brackets or line breaks.

Lip sync or Re-perform, in one paragraph

Lip sync keeps every frame and replaces the sound: all the lines of the segment are voiced again, one after another from the start of the clip with short pauses, and the mouths are moved to match. The original music and ambient sound are not kept. 1 credit per second of the whole clip. Re-perform plays the clip again from itself with the new lines, so timing and delivery fit the words, but the picture can change a little; it costs 2× the per-second price of the clip’s tier and is only offered for clips of 15 seconds or less. How to choose.

Keep it short enough to fit

The new lines have to fit in the clip. Before anything is charged, the site estimates how long they take to say at a natural pace, plus the pauses; if that is longer than the clip, it stops with Too much dialogue for this clip’s length. Shorten the lines. A clip cannot grow longer to make room — for a longer speech, edit the storyboard, give the shot more seconds and regenerate. Shot seconds and timing.

The storyboard is updated too

Changed words are written back into this segment’s storyboard text, only those words, and the panel confirms: The new lines were also written into the storyboard. So if you regenerate the segment later, it says the new line. Voices you pick here are used for this redub; to change a character’s voice everywhere, change it on the character. How character voices work.

Where the result goes

A new version labelled Redubbed in Version History, active straight away if the clip you started from is still the one showing. A segment keeps one redubbed version; the next redub replaces it. The generated clip stays. In an ad project, Lip sync also removes the ad’s music, because it replaces the whole soundtrack; if the ad needs music, try Re-perform on a clip of up to 15 seconds, which makes a whole new soundtrack with the music generated again. If a redub does not go through, the credits come back; in the rare case its result cannot be confirmed, they are held for review. How versions are kept.
