Frequently Asked Questions

  • How does Gemini Omni Flash Preview differ from the Veo models?

    Gemini Omni Flash Preview generates video and then edits it conversationally across turns, carrying the previous clip and its references forward. Veo models generate a clip per request and render at higher resolution. Gemini Omni Flash Preview fits iterative short-form work; Veo fits finished deliverables.

  • How does conversational editing work?

    Each turn references the previous interaction, so the model retains the clip and its references without a re-upload. Send a short instruction such as change the lighting to be more dramatic and Gemini Omni Flash Preview applies it while preserving what you did not mention. Chain turns to branch between versions.

  • How long are the clips and at what resolution?

    3 to 10 seconds at 720p, in landscape (16:9) or portrait (9:16), with landscape as the default. See the Specs table on this page for the current list of supported options.

  • Does Gemini Omni Flash Preview generate audio?

    Yes. Audio generates alongside the video, and you can describe the track you want in the prompt, including background music, sound effects, and events timed to specific seconds. Audio references are not accepted as input, and voice editing is unsupported.

  • What limitations should I plan around?

    System instructions, temperature, top_p, stop sequences, and negative prompts are unsupported, so exclusions go in the prompt text. Video extension and frame interpolation are unsupported, and prompting across multiple videos degrades output. Editing uploaded video is unavailable in the European Economic Area, Switzerland, and the United Kingdom.

  • How is Gemini Omni Flash Preview priced?

    Rates for Gemini Omni Flash Preview are listed on this page as N/A, and N/A breaks out the resolution and duration tiers. Clip length is the lever you control, so shorter clips cost less. AI Gateway reflects provider pricing with no markup and charges no platform fee on inference.

  • Are videos from Gemini Omni Flash Preview watermarked?

    Yes. Every clip carries SynthID watermarking, which viewers cannot see but which can be detected programmatically for provenance verification, along with C2PA content credentials.

  • Which prompt languages does Gemini Omni Flash Preview support?

    English is fully supported. Google has not evaluated other languages, so they may work but results vary. Content safety filters apply to both prompts and generated video and depend on your region.
