02Beach Band Eight Hellos

A single band still becomes a twenty-second rap video cut hard on the beat, and the vocalist greets the camera in eight languages in turn. Seedance 2.5 generates the vocal, the lip-sync and every camera change.

Input imageBand on a golden beach, reference still (@Image1)
Prompt

A cinematic hip-hop / rap music video with photorealistic texture, a premium tone, and a seaside setting. Build the image from @Image1: a band performs on a golden beach by the shore where waves break - a lead vocalist grips a microphone and sings passionately, with the mic stand planted in wet sand; one guitarist stands on the left side of the frame, another guitarist on the right side, and a drummer sits behind a drum kit in the back, playing. A vast coastline spreads behind them, rolling waves surge in layers, and a huge warm golden-hour sunset slants across the beach, sparkling on the water. Sea mist and salty humidity float in the air. The lead vocalist in a red tracksuit raps rhythmically toward the camera - lip shapes and jaw movement precisely match every word, and the head nods hard to the beat, driving the entire flow. The musicians sway and groove with the rhythm while waves crash behind them. This is a bright, energetic rap track - fast delivery, confident attitude, and a powerful beat. Use HARD CUTS on the beat, with dual contrast on every cut (both shot size and camera type change at the same time). Lyrics (the lead vocalist sings the following "hello" in each language in order, with precise lip sync): English: "Hello" Chinese: "你好" Japanese: "こんにちは" Korean: "안녕하세요" Portuguese: "Olá" Thai: "สวัสดี" Spanish: "Hola" Arabic: "مرحبا" Shot 1 [0:00-0:03] - Low-angle extreme wide establishing shot. A Steadicam slowly pushes in through golden sunset light and sea mist, with waves surging behind the band. Lyric line 1 (English "Hello"). Hard cut. Shot 2 [0:03-0:05] - Close-up of the red-tracksuit lead vocalist rapping into the camera, entering with a handheld whip pan, with the sparkling ocean blurred in the background. Lyric line 2 (Chinese "你好"). Hard cut. Shot 3 [0:05-0:08] - Macro insert shot, locked-off camera, a guitarist's fingers rapidly picking the strings as grains of sand and salty mist sweep past the foreground. Lyric line 3 (Japanese "こんにちは"). Hard cut. Shot 4 [0:08-0:10] - 3/4 side medium shot of one musician, slow prowling orbit, with instrument hardware and wet highlights reflecting the low slanting sunset over the sea. Lyric line 4 (Korean "안녕하세요"). Hard cut. Shot 5 [0:10-0:13] - A musician by the shore; a fast lateral dolly move sweeps past them, they turn toward the camera, and a wave breaks behind them. Lyric line 5 (Portuguese "Olá"). Hard cut. Shot 6 [0:13-0:15] - The drummer by the water, handheld fast tilt-up, sea wind and spray blowing through their hair as they groove and strike the drums on the beat. Lyric line 6 (Thai "สวัสดี"). Hard cut. Shot 7 [0:15-0:18] - Tight aggressive push-in on the red-tracksuit lead vocalist at the height of the flow, aggressive handheld, the dusk ocean behind them silhouetting the band. Lyric line 7 (Spanish "Hola"). Hard cut. Shot 8 [0:18-0:20] - Heroic extreme wide shot of the full band, aggressive handheld push-in. The vocalist and musicians step toward the camera on the beat, waves break, and golden sunset light blooms behind the whole band. Lyric line 8 (Arabic "مرحبا"). White balance 4000K, teal-and-amber color grade, 35mm, shallow depth of field, film grain, diffused sea mist, golden-hour glow. Solid, premium, high-end texture. Rhythmic rap performance, precise lip sync, head nodding to the beat. No subtitles, no text overlays, no dissolve transitions, no duplicated people, only hard cuts. Total duration 20 seconds.

Output

03Girl and Fox

The plainest case: one still of a girl holding a fox and two sentences of direction. Seedance 2.5 opens her eyes, pulls the camera back, lets the wind move her hair and adds the sound of that wind to the shot.

Input imageStill of a girl holding a fox
Prompt

A girl holds a fox. She opens her eyes and looks gently at the camera while the fox hugs her. The camera slowly pulls back, the wind blows through the girl's hair, and the sound of the wind can be heard.

Wool-felt rabbits and squirrels play on a handmade miniature meadow, with the subtle frame-by-frame texture of real stop-motion. Visible craft fibers and soft morning light keep every frame warm and tactile.

The Technology Behind Seedance 2.5

How ByteDance's audio-video diffusion transformer scales to 30 seconds.

Long-Context Joint Diffusion

Seedance 2.5 keeps the dual-branch diffusion transformer of 2.0, with video and audio linked by cross-attention, but widens its temporal context so a 30-second clip is denoised as one sequence rather than two stitched halves.

Slot-Based Reference Conditioning

Up to 50 images, video clips, and audio clips are tokenized into dedicated reference slots that every frame attends to, so each asset stays bound to its role—character, location, or rhythm—for the whole clip.

Geometry-Guided Physical Rendering

A textureless 3D blockout conditions the model on layout, depth, and camera path, while its physics-informed world model infers light direction, color temperature, and cast shadows that match the geometry.
