AI Sound Design

A silent AI clip feels unfinished. EasyVid builds the soundtrack with the picture: character voices from the script, audio from video models that make their own, and your music under it all.

How EasyVid builds a video's audio

Scenes from a short film, an explainer, and a music video. Hover one to hear it.

Clip audio

Clips that come with their own sound

Some video models generate sound with the clip. When a dad finds his lawnmower burning, the fire comes with this Seedance 2.5 clip. Keep a clip's audio for a scene or switch it off.

Voices

Every character sounds like themselves

Character voices are generated from the script dialogue, and each character keeps the same voice across scenes. Scene timing follows the dialogue.

One line at a time

Fix a line without touching the scene

Regenerate a single voice line or change its volume. The scene's image or clip stays as you approved it.

Narration

Narration is generated from the script like dialogue, and subtitles are timed to each spoken line in five styles.

Music video

Your song as the soundtrack

In a music video, EasyVid maps the song's beat and sections and times each scene to its bars, so every cut lands with the music.

How to add sound to an AI video

Start from the dialogue, then add music and decide scene by scene whether a clip's own audio should play.

1

Write or format the script

Dialogue and narration become the voice lines.

2

Assign voices and generate lines

Adjust tone, regenerate a single line, or change its volume.

3

Add background music

Upload an MP3, WAV, OGG, or WebM track up to 10 MB and set the music volume for the whole video.

4

Check clip audio

On models that make sound, choose whether a scene uses the clip's audio or its voice lines.

AI Sound Design FAQ

Does EasyVid generate sound effects?

No. EasyVid does not have a separate sound-effect or foley generator. Seedance 2.5 can generate audio with its clips, which you can keep for a scene. For specific effects, use a dedicated audio tool and mix them in after export.

What audio can I add to an EasyVid video?

Character voices and narration generated from the script, subtitles timed to them, your own background music, and native clip audio from video models that generate it.

Can AI video models generate sound?

Some can. In EasyVid, Seedance 2.5 can generate audio with each clip. You choose per scene whether that clip audio plays or the scene's voice lines do.

Can I add my own music?

Yes. Upload an MP3, WAV, OGG, or WebM file up to 10 MB and set its volume. Use music you have the rights to.

Can I adjust audio volume?

Yes. You can set the background music volume, the volume of individual voice lines, and the volume of a clip's audio when a scene uses it.

Are the subtitles synced to the voices?

Yes. Subtitles are timed to the spoken lines, and they follow any line you edit or regenerate. Choose from classic, karaoke, pop, fade lines, and minimal styles.

Can I use my own voice recording?

Yes. Record a line in the browser or upload an audio file for it, and it plays in the scene in place of a generated voice.

How do I add detailed sound effects?

Download the finished MP4 from EasyVid and add the effects in a video or audio editor. Keep EasyVid's voices and music as the base, and lay the effects on top.

Does the music follow the video's cuts?

In a music video, yes: EasyVid maps the song's beat and sections and times each scene to its bars. In other videos the music plays as a background track under the voices.
