Playground / Video / LTX-2.3 Dub-It
Service integration coming soonRedub a video with LTX-2.3 Dub-It
Prepare an existing video and the words you want its speaker to say. Dub-It uses the video and its original audio as references while it generates replacement speech and matching lip movements.
1. Source video
Choose a clip with a visible speaker and an audible original voice. Your file stays in this browser preview; it is not uploaded while the Medux service is being connected.
2. Replacement dialogue
Write the exact dialogue in the target language. Dub-It does not translate it automatically. Include the speaker and language in your prompt.
Generation will be enabled when the Medux Dub-It service is ready.
About this workflow
This is a video-to-video speech replacement workflow, not the audio-driven lip-sync workflow. The model is Lightricks/LTX-2.3-22b-IC-LoRA-DubIt. LTX lists English, French, Spanish, German, and Russian as validated languages. Results may vary with the source clip and dialogue.
