Video Inpainting

What Is Video Inpainting?

Video inpainting modifies selected regions across multiple video frames while preserving the rest of the video.

The workflow typically includes:

Vintage film effects

Scene Expansion and Outpainting

What Is Video Outpainting?

Video outpainting expands scenes beyond original frame boundaries.

Examples:

Widening landscapes
Expanding backgrounds
Creating cinematic widescreen effects
