LTX 2.3 Audio to Video

(01)How it works
How to turn audio into a video
- 01Upload an audio clip between 2 and 20 seconds long (MP3 or WAV).
- 02Add a prompt, a first-frame image, or both, to set what the video shows.
- 03Press Generate. The video length follows your audio.
(02)Tips
Get better results
- For a talking portrait, use a clear, front-facing photo with the mouth visible and closed or relaxed.
- Trim the audio to the part you need before uploading. Dead air at the start becomes a still opening.
- Say in the prompt what should react to the sound: "she sings to camera", "the lights pulse on each beat".
- Clean speech without background music gives better lip movement than a full mix.

FAQ
Audio to Video questions
The things people usually ask before their first generation. Anything else? Ask us.
Between 2 and 20 seconds. The studio checks the length when you upload and tells you if the clip is too short or too long.
No. You can guide the video with a prompt alone, a first-frame image alone, or both together.
Yes. Use the photo as the first frame and a speech clip as the audio. Only animate people who have agreed to it.
Browsing is free. Generating needs a paid plan, and the cost is based on the length of the video.
