Dev Diwali Nov 24, 2026: a diya photo to an 8-second clip for $1.00

Yes. One photo of a diya tray, a courtyard or a riverside step is enough for an 8-second vertical clip, and at 720p it costs $1.00 on Sume. The model is gemini-omni-flash-1.1, which lists $0.10 per second at 720p; Sume bills the list price times 1.25, rounded up to the cent per job. 8 seconds x $0.10 x 1.25 = $1.00.

Dev Diwali (Dev Deepawali) is the festival of lights on Kartik Purnima, the full moon about two weeks after Diwali. Most calendars put it on Tuesday, November 24, 2026, and a few list November 25 because the full-moon tithi straddles two dates. Check the date for your audience's city before you schedule the post. Diwali itself is on November 8 in 2026, so Dev Diwali is the second lights moment for a shop, a temple trust or a tour operator, not a repeat of the first.

What one job costs at each Omni resolution

Gemini Omni Flash 1.1 accepts 3 to 10 seconds, 16:9 or 9:16, with native synced audio that you cannot turn off. The list rates below are from the Video Router docs; the last column is the arithmetic for one 8-second clip.

Submit the photo as the first frame

Put the photo in frame_images with frame_type: "first_frame" so the clip starts from your exact image. Keep the prompt about motion only: flames flicker, a few petals drift, the camera eases in. Ask for a gentle ambient soundtrack, because the audio track is always generated.

Before you post

Review the result the way a person from the community would: check that lamps, garlands and clothing look right and that nothing reads as a different festival. Re-roll with a tighter prompt if it does; every re-roll is another $1.00 at 720p.

If you need a text overlay such as a greeting or store hours, burn it on afterwards with Video captions using authored cues, which need no speech. Omni's own sound is not a voice track, so cue captions are the reliable way to carry the words.

• Photo must be a public HTTPS URL the API can fetch.
• generate_audio: false is a 400 on this model; do not send it.
• Omni accepts only 16:9 and 9:16; for a square feed crop afterwards with Timeline.
