Holiday party invite video from venue photos with an avatar host

A holiday party invite works as a 20-second video: an avatar host says the date and place in one breath, three photos of the venue run behind or after, and the details sit on screen as captions. Christmas Day falls on Friday, December 25, 2026 (OPM, read 2026-10-03), so most parties land in the two weeks before it. Sume renders the host with the avatar route and the venue clips with Seedance 2.5, then Timeline joins them.

OPM supplies the holiday date only. The party's date, time and address are yours, and you should type them yourself into the script and the cues.

Build order

Do the host first, because its length decides the rest.

Write the host line

Keep it to date, place and one reason to come. Do not read the address aloud; show it.

Venue clips

Use real photos of the venue with permission from its owner. Ask for slow camera moves only, and trim each to three seconds with video trim if the model returns a longer clip. A model asked to add decorations will invent decorations that are not there.

Limits

Do not generate a host that looks like a real colleague without their written consent. Check for text on signs in generated clips, which often comes out garbled. Sume does not send invitations or collect replies, so link the finished MP4 from your invite page or email and handle RSVPs elsewhere. The date and venue in the sample script are placeholders.
