Choose Adjust Canvas
Open one compatible video from ClipFlow, Photos, or Files. The original Crop to Fill behavior remains selected by default.
Adjust Canvas · Crop or Expand
Fit the video to the frame you need.
Crop the picture to fill a landscape, portrait, or square ratio, or keep every part visible and expand the canvas around it. Fill the added space with black, another solid color, a gradient, a creative pattern, or a dynamic blurred version of the video.
One canvas, two fitting modes
How to crop or expand a video canvas on iPhone.
Decide whether the target frame should be filled by cropping the source or should preserve the complete picture with background space around it.
Choose how the video fits
Use Crop to Fill to resize and move the visible area, or switch to Show Entire Video to preserve the whole frame inside the new canvas.
Set the ratio and background
Choose 16:9, 4:3, 9:16, 3:4, or 1:1. In Show Entire Video, style the added space, check a sample frame, and create the video.
Crop to fill, or keep everything visible
Crop to Fill is the familiar framing tool: move and resize the selected rectangle or start from an aspect-ratio preset. The chosen area fills the output, so picture outside that area is removed across the complete video.
Show Entire Video takes the opposite approach. ClipFlow scales the full source inside the target canvas and fills only the unused space. Use a solid color—black by default—a gradient, or a built-in creative background. Turn on the dynamic option to use an enlarged, blurred, softened version of the current video behind the complete frame, so the background moves with the foreground instead of remaining static.
Landscape players and vertical feeds
A tall screen recording can sit intact inside a 16:9 or 4:3 landscape canvas, while a 16:9 desktop recording can fit inside a 9:16 vertical canvas without cutting off its edges. Square and 3:4 choices cover additional social and presentation layouts.
Both modes keep the source duration and preserve source audio when present. Core canvas rendering runs on your device, creates a new video, and does not require ClipFlow Pro.
