Gemini Omni Flash 1.1 is worth considering for a game trailer that needs several rounds of changes. Bring character art and short video references, then use follow-up prompts to revise lighting, framing or individual elements. It can generate sound alongside the picture, though the current API does not accept uploaded audio references or support voice editing. Those limits matter if your trailer depends on an existing performance. Keep original art, dialogue and edit notes locally so you can track revisions. Check character continuity and generated sound before publishing, including any rights issues, and compare upscaled delivery options with the native output.
