Thunder lands right after the flash
From one sunset image of a river city. The clouds roll in, lightning flickers behind the towers, the thunder rolls straight after it and rain starts on the water. No music, only the weather.
Sound in every image to video clip · Words in quotes get spoken · One file, nothing to sync
Free image to video AI with sound: upload one image, write what they say and what we should hear, and the voice, waves or thunder come back inside the same video file.
Each of these started as one still image. Turn your sound on: a storm, a pour and two creatures, every noise in the same file as the moving image.
From one sunset image of a river city. The clouds roll in, lightning flickers behind the towers, the thunder rolls straight after it and rain starts on the water. No music, only the weather.
Your image is the first frame. What happens after that image, the movement and every sound, comes from the line you write, and arrives in one file.

Write the image to video prompt like a short scene: who in the image moves, what they say, then what we hear and when.
An image with a face toward the camera for speech, an image of a shore or a street for the air around it, something you can pour, drop or strike for effects.
Say who in the image speaks and how: she says softly, "Can you hear that?" A free 4-second image to video clip fits one short sentence.
List what we should hear and when: waves throughout, thunder right after the flash, rain at the end. Anything you leave out, the generator picks to fit the image.
The video comes back from your image with its audio already inside. Not quite it? Change the line or a sound and make another from the same image; a free account has no daily cap.
The usual route is a silent image to video clip, a voice from a speech app and effects from a library, lined up by hand. This is what changes when the sound comes out of the same image to video render.
A voice laid over a silent image to video clip gets nudged around until the lips line up. A line made with the moving image starts in sync.
The thunder comes on the flash in the image and the splash on the pour. With a sound library you hunt for that frame yourself.
You download one MP4 with the moving image and sound together, ready for your feed or the family chat, with nothing to pair up.
A narration you recorded or a song you own goes on afterwards in your editor: here the sound is made from your image and your words, and there is no audio upload.
Sound is never an add-on here: the free image to video clip has it, and so does every paid one.
Upload an image and press the button: a 4-second video of that image with its sound and no watermark, before you make an account. A countdown shows when it starts.
Keep turning each image into a 4-second video with sound for your own posts, each one saved to your history.
Sharper MiniMax H3 image to video clips up to 15 seconds, long enough for a back-and-forth, plus Grok Imagine Video 1.5 at 15 seconds and Veo 3.1 Fast at 8 seconds, both with sound. Every plan includes commercial use.
Speech comes out clearest when the prompt names who in the image talks and gives every word. Three image to video scenes with dialogue, each kept with the sound its creator posted. For an image that only needs to move, the free image to video AI generator on the homepage takes it the same way.
What the sound in an image to video clip can do, what it cannot, and what is free.
Yes. Every free image to video clip here comes with its sound: MiniMax H3 writes the voice, the air around it and the effects into the same 4-second file. You start with no account, and a free account keeps going with no daily cap.
Yes. Put the words in quotes and say who says them, for example: the man in the image waves and says, "Come on in." The words inside the quotes are the words you hear.
No. The voice and sounds are made from your image and what you type, so there is no audio upload. To use a recording you made or a song you own, lay it over the downloaded video in an editor.
No. You get one MP4 with the moving image and sound together, so there is nothing to line up, and it plays with its sound wherever you post it.
Every image to video clip comes with a sound track; mute it in the player or in the app you post to. To steer what you hear, name the sounds you want in a Sound: line.
Say how the person in the image delivers the line: softly, laughing, out of breath, close to the camera. Put it right before the quotes, the way you would direct an actor, and the voice follows it.
On a free 4-second image to video clip, one short sentence. Plans run MiniMax H3 up to 15 seconds, long enough for two people to trade a few lines.
Yes. Name the sound and the moment it belongs to in the image: a door slam at the start, thunder right after the flash, a spoon tapping the cup at the end. Each one comes in on that moment.
Unlimited MiniMax H3 on every paid plan, plus fast credits each month for Veo 3.1 and Grok. A failed run is refunded.
