AI lets you edit people talking in videos by adding or deleting words from a transcript

Actors who flub dialogue may become less of a bane to producers thanks to an AI that allows such to be edited just by retyping a transcript of their lines. The software works by combining existing clips with digital face models to create new footage that is lip-synced to match the desired edits. The technology could have the potential to be abused to create more creepy deepfake videos that make people appear to say things that they never did. However, the researchers say that these risks are more than outweighed by the benefits of the program, which could also cheaply localise or translate content. At present, the technique only works on videos with a forward-facing interview that are of a particular length - 40 minutes or over.
