how to blur the background in capcut
braza points at the buried canvas 'blur' option so your video fills the 9:16 frame with a clean blurred backdrop.
when a horizontal video sits in a vertical 9:16 frame, you get ugly black bars top and bottom. the fix creators use is a blurred copy of the video filling that space - a 'blur background'. it's hidden under canvas settings, so here's where to look.
or do it yourself
- 1set your project to 9:16 (or whatever ratio leaves bars) via the ratio button.
- 2with no clip selected, open 'canvas' (sometimes 'background') in the right panel.
- 3choose 'blur' and pick a blur strength - capcut fills the bars with a blurred version of your footage.
- 4if you'd rather blur only one clip, select it and look for the same blur option under its background settings.
- 5preview to confirm the black bars are gone.

downloadcommon questions
where is the blur background option in capcut?
deselect all clips and open 'canvas' (or 'background') in the right panel - 'blur' is one of the fill choices alongside color and image.
why does my video have black bars in capcut?
the clip's shape doesn't match your project ratio (e.g. a wide video in a 9:16 frame); a blurred background fills those bars.
