2-second logo sting from Omni: generate 3 s, trim, $0.395 at 720p

Generate 3 seconds and trim to 2. Gemini Omni Flash 1.1 outputs 3 to 10 seconds per clip, so a 2-second logo sting cannot be requested directly. On Sume a 3-second 720p clip is $0.375 and a video trim is $0.02 per job, which is $0.395 for the sting.

The two jobs

First submit gemini-omni-flash-1.1 with duration: 3 and the 720p resolution. Native audio is always on. Then call POST /v1/video-trim on the result with start and either end or duration; it returns a new MP4 with only that range.

Trim needs a workspace-hosted clip, so use the finished artifact, and send an Idempotency-Key on both calls.

Which second to keep

Cut from the end, not the start. A logo reveal tends to resolve in the last second, so keep the range that holds the settled mark, and have the prompt put the mark on screen within the first 2 seconds.

Because sound is always on, check what the clip sounds like before you place it in an edit. If you do not want it, cover it with a soundtrack on a Timeline.

When 3 seconds is fine

If your slot is 2.5 or 3 seconds, skip the trim. The three-second floor is also the shortest Omni clip, which suits a bumper better than a 2-second logo.
