Google began rolling out Gemini Omni 1.2 Flash in Vids on November 5. In the video generation panel, open the Omni settings and move the duration slider. The range for generating a new clip is 3 to 15 seconds where available. Editing an uploaded clip or animating one still uses separate controls and a different range.
Give the final action time
Imagine a tabletop shot showing how to fold a blank place card. Budget two seconds to show the flat card, three for one fold and two to show it standing. Try a seven-second clip with a fixed camera. Write the order and the final hold into the prompt. The times are your editing plan, so check what the model actually produced.
Watch the cut on the timeline
Play the result without reading the prompt. Can someone see the crease and identify the standing card before the next shot? If the fold looks wrong, simplify the action. If the final shape is right but hard to see, give it a separate shot. Check your account's allowance before regenerating: Google lists different limits by edition.
