Las Posadas December 16-24: nine nightly invite videos for $1.93

Las Posadas has nine nights, 16 to 24 December, and each night often has a different host home. One invite still, one 4-second Timeline render ($0.10) and nine caption jobs ($1.80) cost $1.933 with the $0.033 still on Sume. Each night's invite carries its own host and time.

Wikipedia, read 2026-10-03, says the celebration is a nine-night devotional in Mexico, Guatemala, El Salvador, Honduras and Hispanic US communities; it dates to 1586 and has run for over four centuries; participants play Mary and Joseph visiting an 'inn' each night; star-shaped piñatas are broken; and San Antonio has hosted a River Walk procession since 1966. It also notes 'posada' now informally refers to any December office party.

Nine hosts, nine captions

Make one still of a lit doorway, render it once, then burn the host line for each night. The base render stays the same; only the cue text changes.

Respect the occasion

For a religious event, keep the imagery simple and let the community lead the wording. If you use 'posada' for a company party, remember the page says some Catholics object to that use.

What Sume does and does not do

• Does: render nine versions.
• Does not: coordinate hosts or RSVPs.
• Does not: write the songs or the prayers.
