Frequently Asked Questions
What is blur padding?
Blur padding fills the unused parts of a new video frame with a blurred, enlarged copy of the original video. This creates a natural background without cutting off the main footage.
Is blur background better than black bars?
Blur background usually looks more native on social media than black bars because it fills the frame with motion and color while preserving the full original video.
