✳ CROPPING & SIZING
Why doesn't my video fill the screen on mobile?
Compare the video shape with the player area. A 9:16 video fits a 9:16 frame; phones and players can have other proportions. Choose between padding and cropping based on what must remain visible.
Check these first
- Source aspect ratio vs. 9:16
Likely causes
- Source isn't 9:16
When a video in a different shape is placed into a 9:16 frame, the player may crop, pad or scale it. Preview the exact placement; the editing target is not a universal acceptance rule.
Fix it
- Crop to 9:16 before uploading
The linked crop tool center-crops files up to 100 MB; check the generated copy before using it. Use your editor for an adjustable crop or padded canvas, and keep the original.
