Edit your video clips with Gemini Omni in Flow

Omni Flash 1.2 is the Flow model that edits footage you upload.

1. 1Go to flow.google.com in Chrome or Edge and sign in.
2. 2Click + New project.
3. 3In the prompt box, click the model name, select Video, then pick Omni Flash 1.2.
4. 4Set the orientation to match your footage.

You should see a new, empty project with Omni Flash 1.2 picked in the prompt box.

Omni Flash 1.1 retires on December 5, 2026, so use 1.2 for new work.

Omni edits one short segment at a time, so choose the part that matters most.

1. 1Drag your video file into the project.
2. 2If it runs longer than 30 seconds, trim it to 30 seconds when Flow asks.
3. 3In the trimming window, select the segment to edit: up to 10 seconds, or 15 on a paid plan.

You should see your clip in the project, with the segment you picked marked in the trimming window.

Plain words replace the timeline: say what to change and what to keep.

1. 1Type one change in the prompt box, and name what must stay the same.
2. 2Click Generate.

Change the light in this clip to [golden hour, with a warm haze]. Keep the people, their movements and the camera move exactly the same.

You should see a new version of the clip in the asset's stack, with your original kept.

An edit costs the same credits per second as a new clip of that length.

Each follow-up builds on the last version, so you shape the clip without starting over.

1. 1Type a follow-up that changes one more thing, and click Generate.
2. 2You get up to 3 turns of follow-ups on a clip.
3. 3To keep an earlier version, hover over it in the History panel and click Save to Project.

Change the background to a city street at night. Keep the main subject, the golden light on them and the camera angle the same.

You should see the newest version on top of the stack, with the earlier ones listed in History.

Have several clips that need the same fix? Turn on Agent in the prompt box, drag them in and describe the change once.

A reference photo shows Omni who the character is, so they look the same in every clip.

1. 1In the prompt box, click the model name, then Video and Ingredients.
2. 2Drag your character photo into Flow, or type @ to find an image already in the project.
3. 3Describe the new shot and how to use the photo, then click Generate.

Use the person in the reference photo as the main character. They walk into a narrow corridor lit by neon signs, seen from behind at eye level. Same clothes and hair as the photo, warm golden light.

You should see a new clip with the same person in the new setting.

Scenebuilder puts your clips in order, so you can watch the whole sequence before you export.

1. 1Hover over each finished clip, click More, then Add to Scene.
2. 2Drag the clips into order and trim each one with its handles.
3. 3Preview the full sequence, then download the scene as one file.

You should see one video file with all your clips in order.

Every Omni video carries a SynthID watermark you can't see, so it can be checked as AI-made.
