Massive sci-fi battle scene. Thousands of giant, heavily armed mecha robots charge across a desolate, cratered battlefield under a polluted orange sky. Explosions erupt around them. Laser fire streaks across the screen. Camera is low to the ground, emphasizing the thunderous weight and impact of their footsteps. Gritty, intense action, high detail.
A lone, rusty swing set in an empty, foggy playground at dusk. One swing begins to move back and forth *by itself*, slowly gaining momentum, creaking rhythmically. No one is visible. Unsettling, quiet horror.
Cinematic sci-fi suspense. Interior of a vast, derelict, zero-gravity space station corridor, emergency lights flickering erratically. An astronaut floats slowly, using a hand torch to illuminate the drifting debris. They approach a damaged communication console. Suddenly, the console screen crackles to life, displaying a rapid, frantic sequence of unknown alien symbols in bright red before dying again with a final spark. The astronaut freezes, their breath catching (visible condensation inside helmet), slowly turning their head towards the deep darkness at the end of the corridor, as if sensing something is now *aware* of them. Tense atmosphere, handheld camera feel, extreme shadows
Close-up on a bank of flickering security monitors in a dark control room. All screens show empty, static locations (corridors, labs). Suddenly, on *one* monitor, a distorted, glitching humanoid figure flickers into existence for a split second, then vanishes, leaving only static. The camera slowly zooms in on that specific monitor.
Cinematic suspense. Slow pan upwards following creaking wooden stairs in a dark, old house. Dust motes dance in faint moonlight from a high window. Suddenly, the distinct, elongated shadow of someone (or something) standing just out of sight falls across the top landing, lingers for a moment, then quickly retracts.
Tight two-shot inside a parked car at night, streetlights casting occasional moving shadows. A couple sits in tense silence for a moment, avoiding eye contact. One person finally speaks in a low, strained whisper: "We can't keep doing this." The other person looks out the side window, jaw clenched, and replies curtly without looking back: "I know." Focus on their restrained emotions, subtle glances, and the claustrophobic atmosphere.
Extreme close-up, suspenseful thriller. Sweating hands tremble slightly as they use wire cutters to snip a single wire (blue or red?) on a complex ticking bomb. The digital timer shows 0:01. The cutters hover hesitantly for a fraction of a second... then *SNIP*. The timer freezes instantly at 0:00. The character slumps back in relief, breathing heavily. Intense focus on hands and timer. Shallow depth of field, macro shot, extreme tension
Unsettling horror short. A character sits reading a book in a dimly lit, vintage living room. In the background, on a dusty shelf, sits an old porcelain doll with glassy eyes. The character shifts slightly. As they do, the camera subtly rack focuses to the doll. For just a split second, the doll's head seems to be *slightly* turned, its eyes now looking directly at the character. The camera quickly snaps back to the character, who shivers suddenly, feeling watched, and nervously glances over their shoulder towards the shelf, seeing nothing unusual. Creepy atmosphere, shallow depth of field, slow burn tension
Slow, drifting camera shot through the zero-gravity interior of a massive, dark, abandoned space station. Debris floats silently. Suddenly, a forgotten console flickers to life, displaying a single, cryptic alien symbol in glowing green before dying again. Eerie silence, sense of ancient mystery.
Seedance V1 Pro T2V Fast is a next-generation text-to-video model designed for coherent multi-shot storytelling, smooth camera motion, and precise prompt alignment — all while maintaining exceptional generation speed. Built on the same architecture as Seedance I2V, this version allows creators to generate cinematic videos directly from text, with seamless control over style, motion, and timing.
🧠 Intelligent Text-to-Video Understanding Accurately interprets complex scene descriptions, camera actions, and emotional tones to create visually cohesive and narratively consistent clips.
🎬 Multi-Shot Coherence Generates videos with stable subject motion, perspective continuity, and environmental realism across multiple frames.
⚡ High-Speed Rendering (Fast Edition) Optimized for real-time workflows — delivers 480p and 720p videos with high fidelity at nearly twice the speed of standard Seedance models.
🎨 Style Fidelity & Realism Preserves artistic intent, lighting, and visual style while translating pure text into dynamic motion sequences.
📸 Resolution Flexibility Choose between 480p (faster, more economical) or 720p/1080p (higher quality) depending on your creative and budget needs.
| Parameter | Description |
|---|---|
| prompt* | Text description of the scene, camera movement, and atmosphere (e.g., “A wide-angle drone shot of a futuristic city at dawn, sunlight reflecting off glass towers.”). |
| duration | Video length in seconds (3–10s). |
| resolution | Choose between 480p, 720p, and 1080p. |
| Resolution | Price per second | Example (5s) | Example (10s) |
|---|---|---|---|
| 480p | $0.012 / s | $0.06 | $0.12 |
| 720p | $0.024 / s | $0.12 | $0.24 |
| 1080p | $0.048 / s | $0.24 | $0.48 |
Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/bytedance/seedance-v1-pro-fast/text-to-video with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0].

Seedance V1 Pro Fast creates coherent multi-shot Text-to-Video outputs with smooth motion and strong prompt fidelity. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedance-v1-pro-fast-text-to-video.
Seedance v1 Pro Fast Text To Video starts at $0.060 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `aspect_ratio`, `resolution`, `duration`, `seed`, `camera_fixed`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/bytedance/bytedance-seedance-v1-pro-fast-text-to-video.
Average end-to-end generation time on WaveSpeedAI is around 28 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.
Commercial usage rights depend on the model's license, set by its provider (ByteDance). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
