Prompt

Super casual real smartphone home video footage of a sunny beach day outing with friends. Natural mobile phone camera recording with slight authentic handheld shake, normal frame rate with smooth natural motion, rapid-fire montage with constant quick jump cuts every 1–2 seconds like scrolling through phone memories. Unpolished authentic phone recording of a mixed group laughing, playing in the sand, snacking and clicking pictures. Pure raw home video feel with no cinematic polish or heavy effects.

Use the provided reference photo as the STRICT ONLY visual reference for the main woman. Maintain her exact appearance with zero deviation: [her described features]. Generate a mixed group of friends of all ages around her on the beach.

0–2.5s:
Shaky handheld rapid cuts of the main woman laughing with friends near the shoreline. Wind gently moves her hair. Quick flashes of feet in warm sand and waves washing over them.

2.5–5s:
Abrupt jump cuts showing a close-up of her smiling with sunglasses pushed up onto her head, followed by the group splashing water and taking casual selfies together.

5–7.5s:
Fast handheld footage of her sitting on a beach towel chatting animatedly with friends. Snacks and cold drinks are scattered around. Natural sunlight creates subtle lens reflections and realistic exposure changes.

7.5–10s:
Quick cut to a close-up of her giving a big warm smile toward the camera and waving playfully. The footage immediately jumps to the group building a small sandcastle together while laughing naturally.

10–12.5s:
Abrupt edit showing everyone gathered beneath a beach umbrella, casually passing chips and cold drinks around. Friends cheerfully toast with cans while talking over one another.

12.5–15s:
Final rapid transition showing the main woman relaxed and sitting among her friends, softly smiling while looking toward the ocean. The video ends naturally with a gentle phone sway as if someone simply stopped recording.

Reusable method

Key decisions

Check whether camera continuity, transition logic, and action resolution all hold in the final result.

Adapt it to your subject

Extract “target result → the subject, scene, camera movement, and final action → constraints” as a reusable template for similar work.

Where it breaks

Run single-variable comparisons around shot length, transitions, and motion amplitude. Record the model, cost, and failures; turn it into a Skill only after it repeats reliably.
