Funny movie and cartoon redubs with AI character voices
A redub replaces what the characters say with new lines: a serious drama becomes a sitcom, a villain complains about his internet provider. It used to need a group of friends who could do voices; with AI voices one person can voice a whole cast.
This guide walks through a short redub from the script to the finished clip, with free character voices from SuperClonica, and what to keep in mind about copyright before you publish it.
Pick the scene and write the lines
Short scenes of 20 to 60 seconds with a few clear shots of faces work best. Write down when each line starts and how long the character’s mouth moves, then write a new line of about the same length: a joke lands when the timing matches the picture. Keep each line short, one or two sentences, so it is easy to fit.
Voice the cast
Give every character a voice from the SuperClonica catalog: a deep villain, an announcer, a narrator, a cartoon voice. On a voice’s page you can voice a line of 30 to 100 characters for free and download it; listen to two or three voices with the same line before you choose. For a long redub, install the free SuperClonica engine and voice all the lines offline in one go, with no limits. Punctuation shapes the delivery: commas and full stops add pauses, and the guide to pauses and pronunciation has more tips.
Remove the original voices
The background music and sounds make a redub believable, so keep them and remove only the speech. Open source separation tools such as Demucs split a soundtrack into voice and the rest; some video editors have a similar voice isolation feature. Without a clean background you can also replace the whole soundtrack with music and add the effects you need.
Edit and publish
In CapCut, DaVinci Resolve or Premiere Pro, put the cleaned soundtrack under the video, place each new line where the mouth moves and trim it to fit; the guides to these editors show how to add voiced lines. Clips from films and cartoons belong to their owners: what is allowed as parody differs by country, and platforms may block or mute copyrighted footage, so your own footage or licensed clips are the safest choice.
