Step-by-Step Example: Resizing a Landscape Video for Reels

Scenario: You have a horizontal video, but you want to post it as an Instagram Reel (vertical) without cutting off the sides.
  1. Step 1: Upload your horizontal video file.
  2. Step 2: Select the “Instagram Reels (9:16)” size button.
  3. Step 3 Under fit options, select “Fit with Blur”. This fills the empty vertical space with a blurred version of your video, keeping the original footage intact.
  4. Step 4: Click “Resize Video”.
  5. Step 5: Use the “Preview” feature to review the changes.
  6. Step 6: Download your perfectly sized Reel and post it!

Note: We support all major video formats including MP4, MOV, and AVI.
