How it works

How to use Audio to Video

1

Upload an image and an audio file

Upload a portrait or scene image as the visual base, then attach the audio track (speech, music, or ambient sound). Both inputs are required — the image provides the visual frame while the audio drives the animation.

2

The pipeline syncs audio to animation

Sora 2, Runway, or PixVerse analyzes the audio waveform and drives facial animation, scene movement, and rhythm in sync with the audio content. Speech audio produces the most accurate lip movement.

3

Download the merged MP4

Submit the job. Audio and video are delivered as a single merged MP4 file from your history page — ready to upload to social media or embed in a presentation.

FAQ

Video tool FAQ

Can I use any type of audio — music, speech, or sound effects?
Speech audio produces the most accurate lip-sync and facial animation. Music clips create rhythmic scene motion. Ambient sound files drive subtle environment movement. All three formats are accepted.
Does the audio-to-video converter generate lip sync from speech?
Yes — when the audio contains speech, the model maps phoneme timing to mouth shape animation on the portrait. Accuracy is highest with a clean, clear voice recording and a forward-facing portrait image.
How long can the audio file be?
Most routes accept audio clips up to 60 seconds. Longer audio can be split into segments and the resulting clips chained in a standard video editor after generation.
What is the difference between this tool and the talking avatar creator?
Both tools use audio-driven video synthesis. The audio-to-video converter handles general scene animation for any image and audio pairing. The talking avatar creator is specifically optimized for portrait-plus-voice combinations with a dedicated lip-sync conditioning layer.
