How is blur pad different from aspect pad?

Aspect pad fills the bars with a solid color, while blur pad fills them with a blurred, zoomed-in copy of the video itself. This creates a more visually appealing result. Both tools process files locally on your server.

Can I control how blurry the background is?

Yes, you can adjust the blur intensity to make the background more or less soft. A higher value creates a smoother, more abstract fill. The setting is applied during local processing on your own instance.

Does this work with vertical videos?

Yes, blur pad is ideal for converting vertical (9:16) videos to horizontal (16:9) format. The sides are filled with a blurred version of the footage for a professional look. All processing happens privately on your server.
