Sail schools caption the boat and the syllabus; do not generate students
Lock the keelboat still, overlay ASA levels, and do not generate photoreal learners on intro courses.
Lock the keelboat still. Overlays for ASA levels. A photoreal learner is a likeness risk on intro courses.
A sail-school ad that books is the boat they will step onto and the syllabus they will pay for: the keelboat on this mooring, ASA 101 / 103 / 104 as type you typed. It is not a generated class on a cousin hull. The boat is identity. The level is copy. A generated student is a private person you do not have, often on a course that includes minors.
The keelboat still is the school
Walk-up students buy a hull they will stand on. They know the dodger, the sail number, the dock, the club burgee. Text-to-video will invent a movie yacht: prettier teak, a cousin keel, a harbour that is not your county. That yacht is a school you do not insure.
Photograph the boat you actually teach on. Same lens height you would use for a listing. Hull, rig, the name on the transom if you are allowed to show it. Crop faces on the next slip. Crop other schools’ hulls. The still is the contract.
Surf schools is a nearby lesson audience: occupancy of a wave and a student who actually stood up. This page is not that page rewritten. A sail school can film a real student when the grant covers the photo and any generation from it. Most intro-course ads do not need that grant. They need the keelboat and the syllabus line.
Do not prompt “happy beginners learning to sail at golden hour.” The model will pick faces. Average is not your waiver. Average is a likeness on a course that often includes teenagers.
Overlay ASA levels; do not generate students
Muted autoplay still needs the level, the hours, the “keelboat, not dinghy” line. Wan will not typeset those. A video prompt that asks for a syllabus in the sky will invent a HUD, restamp it every frame, and still be wrong on the next session.
Add a text overlay burns one authored line, whole clip, top / center / bottom: “ASA 101,” “Basic Keelboat,” the next open date you actually run. You write the line. It does not transcribe. A mute hull has nothing to listen to. If the copy changes on a clock — level, then hours, then CTA — that is timed overlays, not one persistent badge.
Write the levels you actually teach. Do not let a model invent an ASA number. A hallucinated “ASA 105” on a school that stops at 104 is a syllabus you now advertised. Proof the string against the calendar. Crop to 9:16 before you overlay.
Do not generate learners so the boat looks staffed. A photoreal student is a person. Intro courses are where that risk is worst: mixed ages, family bookings, faces you cannot release. Empty deck stills are honest.
If you need a human, film a real student with a grant that covers the photo and any generation from it. A likeness release that covers AI generation is that paperwork. Most sail-school ads do not need it. They need the hull and the overlay.
Wan 2.1 I2V after the boat holds
Once the still would pass as the listing hero, motion is allowed. Wan 2.1 Image to Video is the still-to-clip row: image required, audio empty — this is a silent row — durations 5s, 10s, 15s, max output 1080p, catalog credits 80, discounted. Qualities listed: 480p, 720p, 1080p. The ceiling is 1080p. Do not prompt 4K.
Open it from image-to-video. Frame one is the file. Prompt camera and weather — a slow push down the sidedeck, light on the sail cover, a slight parallax on the mast. Do not re-describe the hull. Do not prompt “students board.” The still did not have students. Adding them is a generate of people.
Start at 5s. Fifteen seconds of the same transom is a long miss if the hull was already wrong. Because audio is empty, quoted lines in the prompt do not become a soundtrack. Score later if you want a bed. Keep lips out of frame because there are no lips to begin with. If a face appears that was not in the still, throw the file away.
A last frame is optional. Use one when you photographed two states of the same boat — docked as first, sails up as last. Two hulls is a morph. A loop of one still is ambient motion, not a demo of the syllabus.
What this listing is not
It is not a destination film of the harbour. It is not a text-to-video “learn to sail this summer” paragraph. It is not a talking skipper over a generated chart. Do not I2V a stock yacht from another marina and caption your ASA hours. The hull is the contract. The level is the offer.
Pause on the transom. If a student would not recognise the boat from the freeze-frame, you used text-to-video or someone else’s hull. Real keelboat. Overlay the level. No invented learners.
FAQ
Can we generate students if we do not show faces clearly?
No. A blurred or distant photoreal person is still a person you invented to sell a course. Overlay the ASA line. Keep the deck empty, or film a real student with a grant that covers generation.
Why Wan 2.1 instead of a native-audio cinematic row?
Because the product is a silent hull still plus type. Wan 2.1 I2V is audio empty, 5s / 10s / 15s, 1080p, eighty credits listed and discounted. A talking harbour generate will invent students and a cousin yacht. Score after lock if you want a bed.
Is a single overlay enough for the syllabus?
If one line never changes, yes — one persistent overlay. If the copy changes on a clock (level, then hours, then CTA), use timed overlays. Do not ask captions to transcribe speech. There is no speech on this plate.
Is the surf-schools page the right surface for a keelboat course?
No. That page is occupancy of a wave and a student who stood up. Your listing is the keelboat plus the ASA overlay. Link buyers to the syllabus, not to a surf reel.
