Keep a 2-minute video long-form on YouTube: render 1920x1080
Timeline 1.0 renders 1080x1920 by default. Set output width 1920 and height 1080 to keep a short video out of the Shorts class. YouTube's rule and the request.

Replace the presenter in a 3-minute training video with H3 Max Recast

Polling 200 video jobs every 30 s is 400 calls a minute: do this
A poll loop copied to Sume's 30 s example turns 200 open jobs into 400 status calls a minute. Use next_poll_after_seconds, backoff, or a webhook plus sweep.

A 16:10 recording needs crop width 0.3515625 for 9:16: 900x1600 at 2560x1600, but 674x1200 at 1920x1200 because 675 is odd. The request and the rounding.

Three-minute YouTube Short from six 30 s AI clips: Wan vs Seedance
YouTube counts square or vertical videos up to three minutes as Shorts. Six 30 s 9:16 clips cost $22.50 on Wan 3.0 at 720p or $104.04 on Seedance 2.5.

Caption design colors: hex, rgb(), rgba() or transparent only
Sume caption design colors take hex, rgb(), rgba() or transparent. Other CSS syntax is rejected at request time, so a bad color costs nothing.

30-second Wan hero plus two 15-second cutdowns: trim, not regenerate

SHA-256 the batch body into the Sume idempotency key for bulk chunks
Derive each bulk chunk's Idempotency-Key from a hash of its items so replays reuse the queue and edited rows get a new key instead of a 409 conflict.

TypeScript union for Sume bulk queue items, checked with Deno
Model queue items by status so run_id and error are typed per case: null while queued, null for a child that never started, and an exhaustive switch.

Put a new picture on the TV or a frame in a room photo
Swap what is on a TV screen or in a picture frame in a room photo by sending the room first and your artwork second to Ideogram 4.5 on Sume. Cost and checks.
