7 daily 6-second event countdown teasers in 9:16 for $6.65

Seven vertical countdown teasers, one a day for a week before an event, cost $6.65 on Sume. The clips are 6-second, 9:16 Gemini Omni Flash 1.1 jobs at 720p ($5.25), and captions are $0.20 per job ($1.40).

Omni is the fit because it makes 9:16 natively, runs 3 to 10 seconds, and generates its own audio. You do not need a separate sound job for ambient crowd or venue noise.

Each day is one clip and one caption job. Pick the resolution the platform will actually show.

Make the days differ

A countdown only works if each day looks like progress. Generate each clip from a different first frame: the venue exterior, the stage, the lineup board, the doors. Keep the date as caption text rather than asking the model to draw numerals, because generated video text drifts between frames.

Captions are a flat $0.20 per job on video captions, so the day number and the date go in as caption cues, not as pixels the model has to get right.

Submitting the week in one go

The seven jobs are independent, so submit them together with a distinct Idempotency-Key each, such as countdown-day-1 through countdown-day-7. Poll each job's status and fetch the result when it is ready. A fixed key per day means a retry after a network timeout is not a second charge for the same day.

If one day's clip misses, resubmit just that day with a new key. At 720p that is $0.75 for a 6-second retry, so a week with two retries is $8.15 plus captions.

Limits to know

Omni outputs 16:9 or 9:16 only. A square event card needs another route. Sume does not schedule or post the clips: you render the seven files and upload them yourself.
