What makes Gemini Omni 1.2 Flash Video Extend different
Sound is part of the prompt
Gemini Omni 1.2 Flash renders dialogue, music and sound effects in the same generation as the picture. Put spoken lines in quotes, name the music mood, call out the sound effects, and they happen in the clip. There's no separate audio pass and no lip-sync step afterwards.
Up to 15 seconds, any whole second
Pick any length from 3 to 15 seconds, 50% longer than the previous Omni. Every provider bills per second with no base fee, so a 10-second 720p clip is $0.45 and a 15-second one $0.68.
Draft at 360p, finish in 4K
360p drafts cost $0.20 for 10 seconds, so you can iterate on the idea cheaply, then render the keeper at native 720p or upscaled 1080p ($0.50) and 4K ($1.10). Landscape 16:9 and vertical 9:16 are both supported.
Five modes in one family
Generate from text, animate a first frame (optionally into a last frame), guide it with up to 6 reference images and short clips, edit an existing video with one sentence, or extend a clip by 3 to 10 seconds. Every run goes to the cheapest provider for your settings, billed at cost with 0% markup.
