Resize a video for any platform

Good to know

A small or low-resolution source still looks soft when made bigger: the blurred background hides that better than cropping in.

Questions

How do I resize a video without cropping it?

Pick "Whole video, blurred background" (or black or white bars). The whole picture stays and the empty space is filled.

What size is best for TikTok, Reels and Shorts?

1080×1920 (9:16). Instagram feed posts look biggest at 1080×1350 (4:5), YouTube at 1920×1080.

My subject is not in the middle. What can I do?

With "Crop to fill", slide "Keep" to choose the left, middle or right part (top or bottom for tall videos). If the subject moves, auto-reframe follows faces.

Is there a length or size limit?

No account, watermark or length limit. Your computer does the work, so long videos take a while.
