Haunted house ticket teaser: three stills, one 18 s render, $2.68

A haunted house promo can be three 6-second clips joined into one 18-second vertical teaser, with a music bed and the ticket dates burned in as text. On Sume the whole job prices at $2.675: three Wan 3.0 image-to-video clips at $0.75 each, one Timeline render at $0.10, one music generation at $0.125 and one caption job at $0.20. Every price below comes from Sume's docs and catalog, with the 1.25 house multiplier already applied.

This post does not use any attendance or spending statistic, and it does not claim what a teaser will earn. It prices a build you can run and check.

The three stills

Use three photos you already own: the front door at dusk, the corridor and the actor in costume. Each becomes a 6-second clip through the Video Router. Wan 3.0 is a flat per-second rate by resolution: list $0.10 per second at 720p, times 1.25, is $0.125 per second, so a 6-second clip is $0.75. The video models guide lists Wan 3.0 and Seedance 2.5 with their resolutions and aspect ratios, and 9:16 is accepted by both (video models).

Seedance 2.5 is billed by tokens instead. At 720p a 6-second 9:16 clip is $3.4668, so three of them would be $10.40. Pick it when motion quality matters more than the price, and test one clip first.

One render, no audio spine

Timeline 1.0 takes ordered video slots and can run with audio.mode set to silence, which declares an output length with no spine file. A soundtrack bed can be added on top; duck_db needs a real spine, so leave it off. Transitions between slots include fade, dissolve and wipeleft. The public rate is $0.10 per output minute, rounded up, so an 18-second render is $0.10 (Timeline).

• Slots: three, each 6 seconds, starting at 0, 6 and 12.
• Output: width 1080, height 1920 is Timeline's default size.
• Soundtrack: one music file generated through the Music Router, $0.125 per generation.

Burn the dates in with cues

A music-only render has no speech, so speech-to-captions would fail with caption_no_speech. Pass cues with text, start and end instead and the job burns your authored copy without speech recognition (video captions). A caption job is $0.20. Two or three cues are enough: the name of the house, the nights it is open, and where to buy tickets.

All lines at 720p, 18 seconds.

Variants and retakes

If one of the three clips is wrong, regenerate only that slot: $0.75 for the retake, then render and caption again for $0.30. Doing a second version for a different night costs the render and caption again, $0.30, with the clips reused. Check POST /v1/timeline-1.0/plan first: it is unbilled and returns duration, segment count and an estimated cost before you commit.
