FAQ

About youtube short

Is a Short just a vertical video?

Mostly, yes. YouTube detects Shorts by aspect ratio and duration. This preset guarantees the 9:16 frame and a codec profile every device plays back.

What about the Shorts duration limit?

Trim the source first with trim-video or create-social-video-clip; this preset never cuts your content.
