AI Video with Sound and Music
Silent AI video is only half the product. EpicVids carries sound through the whole pipeline, from native audio generation to the final stitched film.
Many AI video workflows generate a mute clip and leave the audio to you. EpicVids offers video models that generate their own synchronized audio: ambience, effects, and spoken lines in the same pass as the pixels.
On top of that, any video can take an AI-generated music track. One sentence describes the mood, one flat price covers the track whatever its length, and the render mixes it under the finished film.
How it works
Pick a model with native audio
The studio marks which models generate sound. Choose one and every scene arrives with its own synchronized audio track.
Direct the sound in the prompt
Scene prompts can carry audio direction: ambience, effects, or a spoken line. The AI planner writes per-scene audio directions automatically on planned videos.
Add a soundtrack
Describe the music in one line and a full track generates at one flat price, whatever the length. The final render mixes it under your film.
Sound survives the stitch
Scene audio is preserved when scenes are stitched into the full film, so the finished video keeps every model-generated sound.

Frequently asked questions
Which AI video models generate sound?
On EpicVids: Kling 3.0 Pro, Vidu Q3, PixVerse V6, Seedance 1.5 Pro, and Happy Horse all generate native audio with their video. Their prices already include the audio.
Can AI video characters speak?
On native-audio models, a spoken line written into the scene prompt comes back as audible dialogue in that scene.
How does the AI soundtrack pricing work?
Music is one flat price per track regardless of length, generated from a one-line description and mixed under the finished video.
Is audio extra on top of the video price?
No. Models with native audio are priced with audio included. The optional music soundtrack is the only separate line item, at its flat per-track price.
