Season finale of 3 minutes: six Wan 3.0 jobs and a timeline, $22.80

A three-minute season finale on Wan 3.0 is six 30-second jobs, because Wan 3.0 accepts 2 to 30 seconds per job. At 720p Sume bills $0.125 a second, so each job is $3.75, six jobs are $22.50, and a three-minute Timeline 1.0 render adds $0.30, for $22.80 before any audio extraction. Treat the cuts between jobs as scene changes you plan, not seams you hide.

The arithmetic

The Wan 3.0 rates are the fal list prices of $0.05, $0.10 and $0.20 per second at 480p, 720p and 1080p, multiplied by Sume's 1.25 house margin. The Timeline fee is $0.10 per output minute, and a 180-second output is exactly three minutes.

All numbers here come from the Wan 3.0 list rates of $0.05, $0.10 and $0.20 per second at 480p, 720p and 1080p, multiplied by Sume's 1.25 factor, plus the $0.10 per output minute Timeline fee. Retries and failed jobs are not included.

Plan the scene breaks before you write

Six independent jobs cannot share a single continuous shot. Write the finale as six scenes that each end on a natural cut: a door closes, a phone rings, a character walks out of frame. Give every job the same reference images and the same style sentence so the cast looks alike, and open each scene with the first frame you want by sending it as first_frame in frame_images.

Wan 3.0 also accepts reference images, videos and audio, so a recurring voice or face can ride along in every request. Read supported_input_references from GET /v1/videos/models to confirm what the model accepts today.

Sound across six clips

Timeline 1.0 joins picture to one audio spine. If the sound of each Wan job is part of the finale, extract it with audio detach and give the files to the timeline as audio.parts (up to 20 gapless slices). If you would rather score the finale with one music bed, send it as the soundtrack with a duck_db and keep dialogue on the spine.

Run order and retries

Submit the six jobs with distinct Idempotency-Key values, such as the season, the episode and the scene number, and poll or take a webhook for each. If scene 4 is wrong, regenerate only scene 4 at 720p ($3.75) and re-run the $0.30 timeline. Draft at 480p first if you are still changing the script: the same six scenes cost $11.28 at 480p, and a replaced scene is only a quarter of that.
