Google Flow Try it →Watch full video →AI2Play · Oct 2025

Demo summary

The user demonstrates the Scene Builder interface to rearrange clips and uses the 'extend' function to generate a continuation of a scene where a character puts on a witch hat.

Step-by-step

Click the 'Add to scene' button on a video clip
Switch to the Scene Builder interface at the top of the screen
Click the plus sign on a clip to view extension options
Select 'Extend' to generate a continuation of the scene
Enter a prompt describing what should happen next in the sequence
Rearrange the generated clips by dragging them to the desired position in the timeline
Click play to preview the sequence

Options

Use 'Jump to' to transition between scenes using the last frame of a video
Rearrange videos like a traditional video editor

Watch out for

The 'Jump to' feature may not capture the exact end frame desired, potentially resulting in visual inconsistencies like open mouths
Transitions may not be smooth if the original clip ends mid-action (e.g., while a character is starting to talk)

Highlights

“This does what it says. It lets you add different videos and rearrange them like in a video editor.”
