3Watch a short clip to get a feel for Seedance 2.5 before you plan your own video.
Starter prompts for 30-second one-takes, dense reference boards, clay blocking, and timestamp edits. Copy the structure—not every word.
Corridor to spotlighted arena in one continuous take. Face, outfit, and crowd energy stay locked.
One-take handheld tracking: singer adjusts an earpiece backstage, walks a dim corridor with dancers, then steps onto a red-and-black arena stage; camera arcs wide to the cheering crowd; keep face, dress, and stage colors stable.
White clay blocking becomes a dreamy animated flight. Camera path follows the clay; style follows the look board.
Refer to clay render for camera path and blocking; refer to style board for warm fairy-tale materials. Flight through clouds, dive with manta rays, then return to a bedroom as a picture book closes—keep the child character consistent.
Keep the athlete’s motion; restage obstacles, locker room, and match pitch across timestamps.
Using the reference performance video, replace backgrounds by timestamp: outdoor training crates 0–4s, locker-room pep talk 4–10s, stadium goal 10–15s; keep athlete identity and stride physics believable.
Many still refs for venue, soloists, orchestra, choir, and audience. Wide hall open, then intimate closes.
Concert hall sequence; use separate image refs for hall, pianist, cello, violin, vocalist, orchestra, choir, and audience; warm golden stage light; camera moves from high wide to solo close-ups; keep each musician’s appearance stable.
Extend a prior clip: boy with soccer ball, adult chase, street exit—same cast and sound world.
Extend the previous video: keep subjects, style, and sound effects; the boy runs the carriage with a soccer ball, dashes onto the platform, then onto the street; the adult catches him and softens into a smile.
Continuous circular camera around water sleeves and combat beats. Costumes and stage stay consistent.
Cinematic single continuous take; circle the lead opera figure with flowing sleeves, cut to the consort’s water-sleeve arc, then pull wide as a warrior enters with an aerial flip; keep costume colors and stage lighting stable.
Seedance 2.5 is not just a longer clip button. Plan a 30-second arc, load a dense reference board, block with clay when needed, then edit by timestamp instead of regenerating the whole story.
Seedance 2.5 can make up to 30 seconds of video with sound in a single run—opening, product moment, and close—so the look and lighting stay consistent instead of one frozen pose stretched out.
Upload the faces, products, clips, and sounds you want Seedance 2.5 to follow in one go. Say what each file is for so looks and audio stay consistent.
Clay render referencing lets you lock camera paths, poses, and spatial blocking with a textureless model, then apply materials and atmosphere from a style board.
Select a few seconds on the timeline and change only that part—action, camera, or sound—while the rest of the video stays put.
Green-screen, camera-perspective, and reference-based edits keep the subject while restaging environments or lens language for ads and film tests.
Multi-round extensions continue characters, environments, and pacing so longer films can grow from a stable audiovisual language instead of patched one-offs.
Pick Seedance 2.5 when the brief needs a longer one-take, a crowded reference board, clay blocking, or second-level edits—not another short multimodal clip rewritten from Seedance 2.0 habits.
Plan a clear start, middle, and end for the whole clip so the model is not stuck repeating one pose for half a minute.
Allocate image, video, and audio slots against cast, props, and rhythm before you hit generate on a dense board.
Use clay for blocking and a look board for materials when camera path and atmosphere both matter.
Write second ranges for fixes so iteration targets a beat instead of regenerating the entire story.
Pick vertical, square, or wide ratios before generating so longer arcs still compose for Reels, Shorts, feeds, or cinematic previews.
Carry cast, wardrobe, lighting, and sound notes into each extension round, then review seams before delivery.
Compare Seedance 1.5 Pro, Seedance 2.0, and Seedance 2.5 on single-pass duration, multimodal reference depth, clay and motion control, timestamp editing, story continuity, and polish—then verify the active label in your authenticated generator.

Use VidMage to plan a Seedance 2.5 clip: pick how you start, describe the 30-second scene, add references if you need them, generate, then fix only the parts that look off.
Use text when you want a new scene. Use an image or other references when the look, person, motion, or sound must stay consistent.
Say what happens from start to end, how the camera moves, and what sound you want. If you upload references, say what each one should control.
Generate the first clip, check what drifted, then edit that moment or extend the story—no need to rebuild the whole video every time.
Good fit when the job needs longer one-takes, crowded reference boards, clay pre-viz, or timestamp surgery—ads, concerts, education films, and cinematic tests.
Ship longer vertical stories with denser refs and cleaner extends for TikTok, Reels, Shorts, and mute-first caption edits.
Build product and launch films that need multi-ref consistency, green-screen restages, and 30-second narrative arcs.
Explore alternate hero shots, campaign beats, product moments, social cuts, and reference-led variants before production starts.
Prototype action beats, camera movement, lighting ideas, transitions, and stylized shots before committing to a larger edit.
Test visual systems, mood, product styling, reference frames, camera language, and subject consistency before choosing the final direction.
Prepare explainers, demonstrations, scenario clips, and visual examples where the viewer needs to understand motion or cause and effect.
Map the 30-second arc, attach dense references, note timestamps to edit, then hit Generate when you're ready.
