Seedance 1.5 Pro: Text to Video with Audio

Overview

Seedance 1.5 Pro is a text-to-video model that generates short video clips with synchronized audio from a single text prompt or a reference image. While most AI video tools produce silent clips that require a separate audio workflow, this model outputs a finished video where the sound is generated alongside the visuals. On Picasso IA, the whole process takes place in one step: describe what you want, choose your format, and receive a clip ready to use. That makes it practical for creators who want to produce social content, product demos, or short narratives without assembling a multi-tool pipeline.

How It Works

Write a prompt describing the scene, subjects, actions, and any camera behavior you want (fixed or moving).
Optionally upload a reference image to use as the starting frame, or provide a separate last-frame image to control how the clip ends.
Select an aspect ratio from the available options (16:9, 9:16, 1:1, 4:3, 21:9, and others) based on your target format.
Set the clip duration in seconds and toggle audio generation on if you want the output to include synchronized sound.
Submit the request and download the 24fps video file once it's ready.

Frequently Asked Questions

Do I need programming skills or technical knowledge to use this? No, just open Seedance 1.5 Pro on Picasso IA, adjust the settings you want, and hit generate.

Is it free to try? Yes. You can run the model without a paid plan. Usage caps vary by account tier, but basic access is available at no cost.

How long does it take to get results? Short clips at standard settings are typically ready in under a minute. Longer durations or complex scenes can take a bit more time.

Does the model generate audio automatically? Yes. When you enable the audio option, the model creates sound that corresponds to the content in the video. There is no separate audio upload or mixing step.

What aspect ratios does it support? It handles 16:9, 4:3, 1:1, 3:4, 9:16, 21:9, and 9:21. Note that if you provide a starting image, the aspect ratio setting is ignored and the image dimensions take precedence.

Can I reproduce a specific result? Yes. Set the seed value before generating, and reuse that same number later to get the same output. Leave it blank for a random result each time.

What if the output does not match my prompt? Rewrite the prompt with more detail about the scene, the camera angle, and specific subject behavior. More precise descriptions tend to produce closer results.

A handsome man stands atop a mist-shrouded mountain ridge. He wears sleek, practical outdoor gear — a dark charcoal windproof jacket, professional climbing pants, and a backpack over both shoulders. The mountain breeze lightly tousles his hair; his expression is calm and resolute. Behind him, surging clouds and mist swirl among jagged rocks, occasionally parting to reveal distant snow-capped peaks. The camera slowly pushes in from behind as he gazes into the abyss of rolling clouds below. In the frigid air, his breath condenses into white mist, adding natural atmospheric detail. He slightly turns toward the camera, his sharp eyes filled with unyielding determination, and says in a steady, powerful voice: “I like challenges.”

A young astronaut in a worn spacesuit sits in the dim cockpit of a spacecraft. The helmet visor is covered with fog and scratches, and the control panel flickers with orange-yellow lights, creating a tense and lonely atmosphere. The video begins with this static opening frame. The camera then rapidly zooms into the astronaut’s face before cutting to the exterior, revealing the spacecraft racing through a blizzard-like storm of cosmic debris. Sci-fi thriller style. Background music: low electronic synthesizers paired with rapidly swelling strings to build suspense. Sound effects: urgent engine hums and howling space-storm noise. Dialogue: "In the void of space, one wrong move..." followed by a brief silence, ending with: "Mayday... systems failing."
