What is a video storyboard?

A video storyboard is a visual preview strip that shows multiple frames from your video arranged in a grid. It's perfect for creating preview images, analyzing video content at a glance, or sharing a visual summary of your video. Our tool creates storyboards with evenly spaced frames across the entire video duration.

Can I customize the storyboard grid size?

Yes! Our video preview image generator supports multiple grid sizes including 6x4 (24 frames), 4x3 (12 frames), and 3x2 (6 frames). You can also create custom grid layouts. The tool automatically extracts frames evenly distributed across your video to create a comprehensive preview.

What resolution are the storyboards?

Our video preview image generator creates high-quality storyboards at 1920x1080 (Full HD) resolution by default. You can also choose 1280x720 (HD) or set a custom resolution. Each frame in the grid is automatically scaled to fit perfectly within the storyboard layout.
