Is Veo 3.1 being shut down?
Only in the Gemini API, and that has happened: Google shut down the three Veo 3.1 preview models there (standard, Fast and Lite) on Oct 22, 2026, along with gemini-omni-flash-preview, and points to gemini-omni-1.1-flash. The GA Veo 3.1 model stays on Google Cloud, and Flow still lists Veo 3.1 (checked Oct 23, 2026).

Which is better for editing video?
Omni Flash. In the Gemini API you edit by conversation: each turn builds on the previous result through a previous_interaction_id, and you can also edit uploaded clips of up to 10 seconds. Uploaded-video edits aren't available in the EEA, Switzerland or the UK, and voice editing isn't supported. Flow lists no video-to-video for Veo 3.1.

Which is better for extending a clip?
Veo 3.1, for now, but no longer through the Gemini API, where its preview shut down on Oct 22, 2026. The GA Veo 3.1 model on Google Cloud lists video extension, and in Flow Veo 3.1 Lite extends clips. Omni makes a 3 to 10-second continuation from the end of a clip in the API, while Flow still marks Omni extend as coming soon (checked Oct 23, 2026).

Do Veo 3.1 and Omni Flash both make audio?
Yes. Veo 3.1 generates native audio, and Google says Omni Flash text-to-video generates a video with audio. Omni doesn't support uploaded audio references or voice editing. Flow adds preset custom voices, with some voice features limited to certain regions.

Which has higher video quality?
Both list 4K, but differently. Veo 3.1 generates 720p, 1080p or 4K. Omni Flash defaults to 720p, and Google says its 1080p and 4K outputs are upscaled. Flow also has a 360p draft mode for Omni. We haven't run side-by-side quality tests.

How do you migrate from Veo 3.1 to Omni Flash in the Gemini API?
Switch calls to gemini-omni-1.1-flash; the Veo 3.1 preview models stopped working in the Gemini API on Oct 22, 2026. Keep clips at 10 seconds or less, test edits as multi-turn conversations, and check region limits for uploaded-video edits. If you need longer extensions or last-frame control, move that work to Veo 3.1 on Google Cloud.
Migration checklist
- Move any code that called the Veo 3.1 preview models (standard, Fast or Lite) to gemini-omni-1.1-flash; those models shut down on Oct 22, 2026.
- Also move off gemini-omni-flash-preview, which shut down the same day.
- Cap clips at 10 seconds (Omni makes 3 to 10-second clips).
- Rebuild edit flows as multi-turn calls using previous_interaction_id.
- Check region rules: uploaded-video edits and extensions aren't available in the EEA, Switzerland or the UK.
- Drop uploaded audio references; Omni doesn't support them.
- Keep long extensions or last-frame control on Veo 3.1 via Google Cloud.

For longer pieces, a mixed workflow can work: draft and edit short shots in Omni, then extend the one you keep with Veo 3.1 on Google Cloud. That is our suggestion, not Google's.
Free test prompts: try both yourself
Run the same prompt in Flow with Veo 3.1 and with Omni Flash 1.1, at the same length. Google's Omni guide suggests describing a single continuous shot.
Single continuous shot (Omni guide style) UNTESTED TEMPLATE
In a single continuous shot, a barista pours latte art in a sunlit café, slow push-in on the cup, soft morning light, steam rising. No scene cuts. Sound: milk steaming, quiet café chatter.
Multi-turn edit (Omni) UNTESTED TEMPLATE
Turn 1: "A red bicycle leaning on a brick wall, gentle breeze, leaves falling." Turn 2: "Make it night, add a warm street lamp, keep the bicycle exactly the same."
Extend a clip (Veo 3.1) UNTESTED TEMPLATE
Continue the shot: the camera follows the cyclist down the hill, same lighting and colour, same character, smooth motion.
Dialogue with audio UNTESTED TEMPLATE
Two friends at a kitchen table. One says: "You finished the whole pizza?" The other laughs and says: "Technically, you said I could." Natural voices, room tone.
