Why 4:5
In a feed, a 4:5 video is taller than a square one and much taller than a wide one, so it fills more of the screen while people scroll. Instagram shows feed posts up to 4:5; taller videos are cut to 4:5 in the feed anyway, so preparing the file yourself means you decide which part stays visible.
From a vertical 1080×1920 phone video, Crop gives 1080×1350, the recommended feed size. From a wide 1920×1080 video, Crop takes a narrow portrait slice of 864×1080, and Fit with background gives 1536×1920 with the whole picture visible.
Frequently asked questions
What size is a 4:5 video?
1080×1350 pixels is the usual size for Instagram and Facebook feeds.
Should I use 4:5 or 9:16?
Use 4:5 for feed posts and 9:16 for Reels and stories, which fill the whole screen.
Is my video uploaded?
No. The video is processed in your browser and never leaves your device. There is no watermark.
How do I make a horizontal video vertical without cutting anything off?
Choose 9:16 and Fit with background. The whole video stays visible in the middle, with a blurred copy of it above and below.
Does cropping reduce the quality?
The picture is encoded again at high quality, so the difference is hard to see. Cropping does not add detail: a small part of a video enlarged on a big screen looks softer.
Can the crop follow a moving subject?
No, the frame stays in one place for the whole video. Check several moments with the Preview frame slider and place the frame so the subject stays inside.
Is the sound kept?
Yes. The sound is copied, or converted to AAC when the MP4 or MOV result needs it.
