Repurposing landscape videos for vertical platforms

TikTok, Instagram Reels and YouTube Shorts play videos full-screen in 9:16. A landscape 16:9 video only fills a third of the screen, so it’s worth converting it before you post.

Blur fill keeps the whole picture and fills the space above and below with a blurred copy — ideal for landscapes, interviews and screen recordings. Crop fills the entire screen; drag the preview to keep the subject in frame. Zoom is a middle ground: slightly cropped, larger picture.

The empty areas are perfect for a headline at the top and a caption at the bottom. Keep text out of the red safe zones — that’s where the platform shows usernames, descriptions and buttons.
