Guide de prompting Seedance 2.5 (Partie 2) : Montage vidéo, extension et assemblage final

Edit seconds 4–7 of Video 1. Replace only the dark jacket on the person at right with the ivory trench coat from Image 1; its material and folds must respond naturally to the original movement. Preserve identity, expression, body movement, background, camera, lighting, edit rhythm, and original sound. Keep everything before second 4 and after second 7 exactly as in the source.

Edit Video 1. Preserve the original composition, camera, lighting, background, and performance timing. Change only the woman's age and expression.

Let her age naturally from her twenties to her sixties. Her facial structure and identity remain consistent while skin, hair color, and facial detail change continuously, without jumps or flicker. The restraint in her eyes gradually releases, a tear travels from the corner of one eye, and the corners of her mouth slowly rise until she smiles through tears.

Keep the entire shot continuous. Do not change body movement, depth of field, color grade, or sound.

Edit Video 1. Preserve both performers' action order, speed, distance, camera, and original edit rhythm exactly.

Replace the setting with the medieval fortress platform from Image 1: flat stone paving, castle walls, distant mountains, wind, and light mist. Replace the clothing of the dark-clothed performer with the outfit in Image 2, and the clothing of the light-clothed performer with the outfit in Image 3. Keep both identities and faces unchanged.

Add only restrained environmental detail: wind moving the garments, small dust puffs at contact points, cool metallic highlights, subtle film grain, and an epic color grade. No exaggerated magic effects. Synchronize the background score to the original action beats.

Edit the dialogue in Video 1. Translate all speech into natural Chinese and precisely regenerate lip movements for Chinese pronunciation. Preserve the speaker's vocal character, emotional intensity, pauses, and natural speaking rhythm.

Do not add subtitles. Keep the background music, ambience, sound effects, camera, character appearance, action, visual rhythm, and duration unchanged.

Extend Video 1 forward by 5 seconds after its ending. Preserve the same flower, natural light, macro depth of field, color, and continuous ambience.

A bee flies in and lands on the flower. Cut closer to a macro view of golden pollen collecting on its legs and abdomen. It lifts off and the camera follows to a nearby flower of the same species. In slow motion, pollen shakes loose from its hairs and falls onto the stigma, clearly magnifying the instant of pollination.

Do not reintroduce the setting or alter the flower's state in the original last frame. Output MOV.

Arrange Images 1–8 freely into a vertical café check-in vlog about the same dog posing in different cute outfits.

Use hand-drawn animated doodles and light cutout collage as the visual package. Add a restrained number of sketched lines, stickers, and rhythmic transitions for a relaxed social-media feel. Images may have subtle Live Photo-style movement and natural push-ins or pull-outs, but do not alter the dog's identity, clothing details, café furnishings, or original composition.

Generate lively but not overwhelming background music, and synchronize transitions to the beat.

Connect Video 1 and Video 2 seamlessly while preserving the content, speed, and color of both source clips.

Continue from the end of Video 1. The camera races toward the highest point, pauses briefly, then immediately reverses and dives straight down. During the dive, the black-and-white dominoes stretch upward and gradually transform into city towers while the tabletop texture and surroundings become the urban space in Video 2. Camera direction, speed, and motion blur remain continuous until the movement enters Video 2's opening viewpoint naturally.

No black frame, white flash, or visible hard cut. Keep the subject transformation continuous.
