Convert a YouTube video into vertical clips

From 16:9 to 9:16 without wrecking the shot

Reframing is where most conversions fall apart. Simply chopping the sides off a horizontal frame loses half the scene and pushes the speaker out of shot the moment they move.

MomentCut follows the face across the shot and moves the crop with it, so the speaker stays centred from start to finish. When a scene does not suit that, you can keep the whole frame with bars instead, or set the horizontal position yourself.

Choosing what to pull out

Not every segment of a long video works in short form. What works are the passages that need no setup: a clear answer, a demonstration, a surprising number, a disagreement.

MomentCut looks for exactly those in the transcript, scores them, and leaves you the final call. You can also name the topics you care about before running the analysis, to steer the selection.

Captions are not optional

On all three platforms, most playbacks start with the sound off. A clip without captions loses its viewer in the first second, however good the point being made. MomentCut burns captions into the image, with several styles and fonts, and also gives you the SRT file if you would rather upload them separately.

Posting across all three

One vertical file suits TikTok, Instagram Reels and YouTube Shorts alike. The caption and hashtags, on the other hand, are worth adapting per platform — MomentCut gives you a starting point for each clip, to rewrite depending on where it is going.
