Omni edit came back 720p: how to ask for 1080p on Sume
A gemini-omni-flash-1.1 edit defaults to 720p when you leave resolution out. Set resolution on the request; here is what the edit mode accepts.

If your edited clip is 720p, you did not set resolution. On Sume's Video Router the edit mode treats resolution as optional with a default of 720p. Google's Omni page gives the same default and lists 360p, 720p, 1080p and 4K, with 1080p and 4K described as upscaled (read 2026-10-03).
What to send
Higher resolutions take longer and cost more, so ask for 1080p on the final pass, not on every test.
