Sound on every clip · 768p and up to 30 s on paid plans
AI video generator with audio on MiniMax H3: write the scene, the line and the sounds, then post the clip as it comes back, voice and all.
Four AI video clips, posted by their creators with the original audio: a scripted line, hammer blows, a fading roar and a sizzle, all rendered with the picture.
The prompt gave the chipped mug one line, "Every morning.", and a second mug a whisper, "I hate that mug." Both come out in character voices, timed to the mugs on screen. Made by the author on Seedance 2.0.
The creator asked MiniMax H3 for "a heavy ringing hammer strike every two seconds". The sound line set the rhythm of the picture too: the hammer falls on the beat you hear.
Also MiniMax H3: "a waterfall roar that fades in steps as the ice climbs". Each step of ice takes a step of noise with it, until the pool goes quiet.
Hand-pulled noodles hit the counter with a slap, then hot oil meets the chili at twelve seconds with a sizzle you feel in your ears. Seedance 2.5, from stills the creator made first.
An AI video generator with audio writes the soundtrack in the same pass as the picture: the voice comes from the mouth you see, footsteps fall on the frame where the foot lands, and the room sounds like the room. You describe both in one prompt.
If one picture is your starting point, photo to video AI free animates it with sound on the same models.
Creative engine
The words and sounds you write go in with the scene; an MP4 with picture and audio comes out.
Dubbing records a voice afterwards and lines it up by hand. Here the voice is generated with the face, so the timing starts out right.
A stock track is the same song under every AI video. This sound belongs to the scene: this hammer, this waterfall, this kitchen.
A text-to-speech app gives you a voice file with no picture. The AI video generator with audio gives you the person saying it, on camera.
Treat the prompt like a short script: the picture first, then what is said, then what is heard and when.
Who is in the shot, where they are, and how the camera moves. The place decides the room sound before you write a single noise.
Name the speaker and give every word you want spoken: the old man says, "Close the door, the bread is cooling." Add how it is said: whispered, shouted, laughing.
Rain on a tin roof throughout, a door slam at four seconds, the kettle starting to whistle at the end. A beat you can hear is also a cue for when things happen.
One line fits the 8 seconds of Veo 3.1 Fast; a short exchange fits 15 on MiniMax H3 or Grok Imagine Video 1.5; a whole scene with several beats goes up to 30 on Seedance 2.5.
Plenty of people still make a silent AI video, then add a voice from a speech app and effects from a library. Here is what changes when the sound is native.
A voice laid over a silent AI video has to be slid around until the lips line up. A native line is generated with the lips, so there is nothing to slide.
The glass breaks on the frame it shatters and the oil sizzles when it hits the pan. With a sound library you hunt for the frame yourself.
A kitchen echoes like a kitchen and a street hums like a street, because the AI video generator heard the same prompt that drew the room.
No separate voice file, no effects pack, no editor timeline. You download one AI video that already plays the way you meant it.
A ten-minute narration over many clips, or a brand voice you already own, belongs in your editor. Generate the AI video clips with their room sound, then lay the narration over them.
Choose by the clip you need back: H3 for 768p takes with no monthly cap, Grok for a 15-second 720p clip every day, Veo for an 8-second shot, Seedance for scenes up to 30 seconds.
Sound on every AI video, from text or from a photo. 480p in the shared queue on a signed-in account with no daily cap; 768p with no monthly cap from Starter at $14.90. The unlimited AI video generator plans are built on it.
Fifteen seconds at 720p with sound, every day from Creator at $29. The Grok video generator page shows the prompts people use for talking scenes.
Eight-second AI video clips at 720p with native audio, on fast credits from any plan. The Google Veo 3 free page lists what a Veo clip costs.
The longest takes here, up to 30 seconds at 480p or 720p, and the sound is always on. See Seedance 2.5 for what it does with people and food close-ups.
Voice tests before a shoot, cooking shorts, slow kitchen Reels and two-person sketches: AI video clips where every voice and noise was rendered with the picture.
Six seconds, one face, one line in a soft Southern accent, with the breath before it. Filmmakers run tests like this to settle a character's voice before shooting the scene.
Garlic hits hot oil, metal cups clang, and the parrot's tiny feet scrape the galley floor. The author asked for crisp cooking sound and no dialogue.
Piping bags, oven-door clicks and plates set down softly. The prompt listed each of those sounds, and the AI video plays them on cue.
Two actors flub the line, break character and laugh, then go again, with no close-up cuts to hide the timing.
Every model on Movoa does: MiniMax H3, Grok Imagine Video 1.5, Veo 3.1 Fast and Seedance 2.5 all render the soundtrack in the same pass as the picture. H3 runs on any account; the other three open on paid plans.
Yes. MiniMax H3 renders voices and sound at 480p at no cost: your first clip needs no account, and a signed-in free account keeps going with no daily cap, one clip at a time in the shared queue. Plans add 768p, full-speed renders and the other three models.
Yes. Put the words in quotes and say who speaks them, for example: the girl at the window says, "It's snowing." Write every word you want heard; the AI video generator with audio speaks what is in the quotes.
Native. The audio is generated together with the frames in one render, which is why a voice lines up with the mouth and a crash lands on the frame of the crash.
Adding a voice later means a silent clip, a separate speech file and lining the two up in an editor. Native audio arrives already in the AI video. Add your own recording later only for long narration over many clips.
An AI video can carry a few spoken lines from someone off screen if you write them in. A narration that runs across a whole video is easier to record or generate separately and lay over your clips in an editor.
Yes. Upload a photo, describe the motion and the sound, and the AI video comes back with audio on all four models. The photo to video AI free page walks through it.
Give each sound a moment: a door slam at four seconds, a hammer strike every two seconds, the kettle whistling at the end. Each AI video model uses those cues to time the picture as well as the audio.
MiniMax H3 and Grok Imagine Video 1.5 make up to 15 seconds, Veo 3.1 Fast makes 8 seconds and Seedance 2.5 goes up to 30. The generator shows the lengths each model offers before you run it.
Yes on any paid plan, which includes commercial use of the clip and its soundtrack. AI video clips from the free lane are for personal posts and messages.
Unlimited MiniMax H3 on every paid plan, daily Grok with sound from Creator, and fast credits for Veo and Seedance. A failed run is refunded.
