BytePlus Seedance 2.0 text-to-video. Describe a short scene and receive an MP4 clip with natural motion, camera work, and audio. The control panel offers an aspect-ratio selector with 7 options: 16:9 (landscape, YouTube), 9:16 (portrait, IG Reels / TikTok), 1:1 (square, IG posts), 4:3, 3:4, 21:9 (ultrawide cinematic), and adaptive (automatic, decided from the prompt or the first-frame image) — pick by target platform. Upload a first-frame image to set the opening shot; the AI extends motion from there. Upload a last-frame image to set the ending shot; the AI wraps the clip on that image. Upload multiple keyframe images to chain scenes in order — the video traverses them sequentially, ideal for story-driven shorts with multiple scene changes. Strong at Chinese cultural scenes and Asian character animations. Use it for social-media content, product demos, educational shorts, or concept videos. Usage: 1. Prompt only, no file uploads. 2. Prompt + first-frame image. 3. Prompt + first-frame and last-frame images. 4. Prompt + keyframe images (multiple images are chained in upload order). 5. Prompt + reference images, videos or audio. First-frame or last-frame images cannot be uploaded together with keyframes or reference images, videos or audio (a first frame may be paired with a last frame). Generated videos are 15 seconds long at 720P; the aspect ratio follows the control-panel selection (default 16:9). Prompt example 1: A traditional market on the eve of Lunar New Year, stalls hanging red couplets, bustling crowds; the camera slowly descends from above to a rice cake stall. Prompt example 2: (Upload a flower bud as the first frame and a bloom as the last frame) The bud slowly opens into a red camellia in the morning light as a breeze stirs the leaves. Prompt example 3: (Upload three keyframes in order: beach sunrise, city street, mountaintop night view) Join them into a one-day travel clip with smooth transitions and a light pace. Prompt example 4: A glove puppet show at night in a temple courtyard, puppets flipping and sparring on a colorful stage as kids cheer; the camera pushes slowly from behind the audience to the stage. Prompt example 5: (Upload a photo of a seaside guesthouse exterior as the first frame) The camera rises slowly from the front door into an aerial view, revealing the long coastline and beach, for a booking page promo. Prompt example 6: (Upload an empty white room as the first frame and a finished Scandinavian living room as the last frame) Furniture slides in piece by piece, showing the before and after. Prompt example 7: (Upload four keyframes in order: sprouting seed, seedling, green tomato, ripe red tomato) Make a time-lapse of a tomato growing, for an elementary science class. Prompt example 8: (Set the panel to 9:16) A vertical clip: a street performer plays the violin outside a metro station exit as passersby stop to film; the camera pulls back from the strings to a full shot. Prompt example 9: An electric scooter ad: an office worker rides a white e-scooter through city streets at dawn, the body gleaming in the sun, then stops at an office tower, takes off the helmet and smiles. Prompt example 10: (Upload a hand-drawn solar system illustration as the first frame) The planets slowly orbit the sun as the camera pushes in from afar toward Earth, as a science video opening.
