完整 Prompt
🛹 Seedance 2.5 Hover Board T2V+R2V Started simple — text to video, just a couple of short lines. Then attached that 30s piece as a reference and wrote a detailed prompt. Really cool and expensive 😎 ▾ My take and the full prompt below 1. Consistency is unreal, considering the only reference was a video 2. The sound artifacts are gone — audio got significantly better 3. Realism and physics are off the charts Prompt SOURCE AND CONTINUATION Extend @video1. This is a direct continuation that begins at the exact frame where @video1 ends — the same ride, the same day, the next stretch of desert. Every shot below is new material that happens after the source footage, not a retelling of it. Preserve exactly from @video1: the rider's identity, helmet and visor, black riding suit, gloves and boots; the hoverboard and its cyan underglow; the desert world, dune shapes and haze; the low golden sun and its direction; the colour grade; and the music, which continues unbroken in the same key, tempo and arrangement with no restart. CHARACTERS The rider: same man from @video1, full dark helmet with a clear visor and two white light strips, black armored riding suit, gloves, boots. Identical in every shot. He rides the same hoverboard, lit underneath by a continuous cyan strip. LOCATION MAP Foreground: open sand, wind-carved ripples, loose grit lifting off the crests. Midground: the ride path — dunes flattening into a cracked salt pan that runs into a post-apocalyptic ruin field of collapsed concrete slabs, leaning steel columns, half-buried vehicle hulls and broken roadway sections. Background: a low sandstone cliff wall on the far side of the ruins, and beyond it open sky with the sun sitting low on the horizon. The rider travels camera-left to camera-right in every lateral view. The sun stays low and ahead of him, camera-right, throughout. FIRST FRAME / BLOCKING Full-frame lateral profile close-up of the rider, 18°, camera tracking alongside him at his own speed, his helmet filling the right third of frame in sharp profile, dunes streaking past behind him, cyan board glow spilling up onto his boots from below. FORMAT MODE Timed multishot with HARD CUTS only at 4.0s, 8.0s, 12.0s, 15.0s, 19.0s, 23.5s and 27.0s. The camera cuts only at these points. Real-time playback everywhere except 19.0–23.5s, which is slow motion; the speed change happens only on those two hard cuts. STORYBOARD SHOT 1 (0.0–4.0s) Lateral profile close-up, 18°, camera tracking beside him at 60 km/h, level with his shoulder. He rides steady, head turning a few degrees forward as the ruins come into his sightline, then his shoulders drop slightly and he leans in. Sand streams off the board's trailing edge behind him. Low sun rakes across the front of his visor from camera-right, leaving the far side of his helmet in deep shade. SHOT 2 (4.0–8.0s) HARD CUT to an extreme wide, 84°, camera high and static as he crosses the frame camera-left to camera-right at 60 km/h, a small figure with a cyan thread of light beneath him. Ahead of him the ruin field opens up — collapsed slabs and leaning steel standing as tall as six humans, throwing long shadows across the salt pan. SHOT 3 (8.0–12.0s) HARD CUT to a low tracking shot, 47°, camera 30 cm off the ground running with him at 70 km/h as he enters the ruins. He weaves between two leaning columns, board tilting hard onto its edge, a sheet of sand and grit fanning off the tail. Broken concrete passes close on both sides. Cyan underglow flares against the slab faces as he passes them. SHOT 4 (12.0–15.0s) HARD CUT to a medium shot from the front quarter, 29°, camera drifting backward ahead of him at 70 km/h. He drops into a deep drift, both arms out for balance, the board sliding sideways through a curve of debris, a long curtain of dust thrown out behind him and catching the low sun. His head stays locked on his line through the turn. SHOT 5 (15.0–19.0s) HARD CUT to a low rear three-quarter shot, 63°, camera accelerating with him from 70 to 110 km/h. He crouches, drives his weight forward, and the board's cyan strip brightens as it surges. Ahead of him a broken roadway section rises out of the sand at a shallow angle, its torn edge lifted clear of the ground. He hits it square and launches. SHOT 6 (19.0–23.5s) HARD CUT into SLOW MOTION. Wide side view, 47°, camera craning slowly upward with him against the low sun. He is airborne at the apex, board still under his feet, one hand gripping the front edge, knees folded. A full curtain of sand hangs suspended around and beneath him, every grain lit gold from camera-right and drifting rather than falling. The cyan glow underneath him rakes across the suspended sand. The whole shot stays in slow motion start to finish. SHOT 7 (23.5–27.0s) HARD CUT back to real time. Low tracking shot, 47°, camera behind and beside him. He lands hard, board slapping the sand and compressing, a burst of grit blowing outward from the impact, and he rides straight out of it at 110 km/h across the last open stretch toward the sandstone cliffs. The ruins fall away behind him. SHOT 8 (27.0–30.0s) HARD CUT to a lateral profile medium shot, 29°, camera settling alongside him and coming to rest as he does. He carves the board hard sideways and brakes, throwing a low wide sheet of sand forward and to camera-right, and stops at the cliff edge. He straightens up, squares his shoulders, and turns his helmet to face the sun sitting on the horizon. Held final frame: the rider in profile at the cliff edge, sand still settling around the board, the cyan glow steady beneath him, the sun low ahead of him. PERFORMANCE Everything reads through the body, since his face is behind the visor: weight shifting into each turn, arms counterbalancing the drift, the deep crouch before the launch, the folded stillness at the apex, the absorbed compression of the landing, and the settled straightening at the very end. Restrained and controlled throughout — a rider who knows this ground. PHYSICS The board carries real mass and inertia. It leans into turns and rebounds on landing. Sand behaves as loose dry grain: it fans off the edge under load, hangs in a curtain in slow motion, blows outward in a burst on impact, and settles slowly at the end. Dust catches and scatters the low sun. Wind drags loose grit off the dune crests continuously. Debris in the ruins stays put; only sand and dust move. LIGHTING Fixed 3200K golden-hour sun, low on the horizon ahead of the rider and camera-right, unchanged in every shot. Hard warm key on the front of his suit and visor, deep shade on the far side, long shadows running away camera-left across the sand and the ruin floor. Airborne dust glows where it crosses the sun. Cyan board light acts as a cold practical from below, catching his boots, the sand under him and nearby slab faces. AUDIO The music from @video1 continues unbroken through the whole extension — same track, same key, same tempo, no restart and no new song. Under it: the low hum of the board, wind across open sand, grit spraying off the edge, concrete and steel echoing close in the ruins. At 19.0s the mix thins for the slow-motion shot — the music drops to a single sustained low note, and the suspended sand and the board's hum sit at the front. At 23.5s the full arrangement returns hard on the landing impact. In the final shot the music resolves and holds under open desert wind. No dialogue anywhere. OUTPUT SETTINGS 16:9, real-time in every segment except 19.0–23.5s, which is slow motion. POSITIVE LOCKS This is a continuation of @video1 — all action takes place after the source footage ends. The rider, helmet, visor light strips, suit and the hoverboard's cyan underglow stay identical to @video1 in every shot. The rider travels camera-left to camera-right in every lateral view, and the sun stays low and camera-right in every shot. One continuous piece of music runs from the first frame to the last, carried over from @video1. The board keeps complete geometry and stays under his feet through the jump and landing. Cuts land only at the stated seconds, and the speed change to slow motion happens only at 19.0s and back at 23.5s. The video ends on the held profile of the rider stopped at the cliff edge, facing the low sun.
