Gemini Omni 1.2 Flash Upscale increases video resolution. Input: a 16:9 or 9:16 clip up to 15 s at exactly 640x360, 1280x720 or 1920x1080 (or the vertical equivalents). Targets: 360p to 720p or 1080p, 720p to 1080p or 4K, 1080p to 4K. Frame count, duration and audio are kept (we measured the audio identical, offset by about 43 ms); only resolution and detail change. Typical use: draft at 360p with the Omni 1.2 base model, choose the best take, then upscale it. Has no prompt and does not change content.
