Dunk tanks are first-last dry seat to splash, not a talking host

Two stills of the same tank. Veo first-last interpolates water. generate_sound_effect for the splash; do not put a generated person on the seat.

A dunk tank is a structure with a dry seat and a wet seat. The ad is the drop. Photograph both states — seat up, then water in the air — with nobody on the plank you did not have the right to shoot. Interpolate the water. Score the hit as a sound effect. A constructed host on the seat is a likeness problem. Keep the tank. Leave the person off the generate.

Same tank. Dry seat, then splash.

Photograph the unit where it sits — same lens height, same wrap. Seat up, tank full, nobody on it: first frame. Water in the air, same standing spot: last frame.

First-last frame takes those two stills and generates the motion between them. Ordinary image-to-video improvises the rest. First-last has to land. The wrap and the target stay the SKU because they are in both photographs. Same tank, same crop. A close-up of the target morphing into a carnival wide is a warp, not a dunk.

Create a first-and-last-frame transition video is the named agent job: two photos in, one transition out. Cost is priced per model, shown before you confirm. A loop (same still in both slots) is not a dunk. A different wrap as last frame is a morph of the rental.

Veo first-last interpolates water

VEO First Last Frame interpolates between first and last frames. Image-to-video. Native audio on. Durations only 4s, 6s, and 8s. Output quality includes 720p, 1080p, and 4K. Aspect ratios 16:9, 9:16, and auto. Catalog sticker: 40 credits. It does not invent a tank from a paragraph. It does not extend a keeper. It spends those credits to travel from a still you already approved to a still you already approved.

Prompt the travel, not the carnival. Name the mechanism: seat trips, water erupts, camera locked, wrap unchanged, no person added to the seat. If the endpoints share geometry, the morph reads as a dunk. If they do not, you get a mushy crossfade.

4s, 6s, 8s — there is no ninth second on this row. A splash that reads in two seconds looks padded at eight. An eight-second travel that invents a crowd in the middle is the miss.

Native audio rides along. A silent prompt still gets a soundtrack you did not choose. Write room tone only — the splash you want is a spotted effect. 4K is the ceiling, not a default. Inspect the midpoint. If the middle grows a face or a crowd, reroll. Do not regenerate both stills "to match the motion."

generate_sound_effect is the splash. It is not a host.

Generate a sound effect is one named agent job: generate_sound_effect from a prompt, optionally with duration and loop. Describe the hit — a body-of-water splash, a tank slap — not a voice. You get a short audio clip. Cost is per generation, shown before you confirm.

That is not a song. generate_music writes a track. Generate the splash. Place it. Slip it a frame if the water is late. Regenerating the Veo take so the picture accidentally matches a baked-in ambience is the expensive diagnosis. Say whether it loops. Say how long. Do not ask the SFX model to "sync to the video." Sync is an edit: nudge the start.

Native-audio Veo already baked some room. Use this job for the impact the bake missed. Do not pay the 40-credit video row again hoping the next take's ambience is Foley. Speech is not a sound effect. A host line is a real named person on a different day, or not at all.

Do not put a generated person on the seat

The seat is the product. A constructed person on it is a likeness you do not have. Do not generate a volunteer or a crowd. If a real person sat, you need their consented still in both ends, or keep them out of the generate. If someone must speak, that someone is a real named person on a different take.

Equipment rental companies teach the tool so a renter will book. That page is familiarisation for machines. It is not a dunk-tank SKU still. Copying it here — generated operator, generated safety lecture — is how a wrap becomes a talking host. Overlay a booking line after lock if the feed needs type. Same tank, two water states: this page. Real machine demo: /for.

FAQ

Can I animate one photo of the dry tank and hope it splashes?

You can. The ending is then the model's guess, and the guess often includes a person. Pin the splash still — empty of unconsented faces — as the last frame or you are not selling the dunk.

Why not let Veo's native audio be the splash?

Native audio is on, so a silent prompt still gets a bed you did not choose. That bed is not a spotted hit. generate_sound_effect is the splash file you can slip. Regenerating the 40-credit interpolate to chase a transient is the expensive order of operations.

Can I put a generated principal on the seat if I label it AI?

No. You do not have that likeness, and a constructed person on the plank is the wrong object. Photograph the tank. Keep people off the generate unless they were in the stills you had the right to shoot.

Is this the same job as the equipment-rental /for page?

No. Equipment rental companies teach operation so someone books a machine. This page is two stills of a dunk tank and a splash effect. Overlay a booking line on a locked tank. A generated host is not a wrap.
