How to Reframe Horizontal Video to Vertical (16:9 to 9:16)

A 16:9 frame is wider than it is tall. A 9:16 frame is the opposite. If you keep the full height and crop the width, the vertical window shows roughly 32 percent of the original width. Everything outside that window is gone, which is why a two-person interview or a wide screen recording can't simply be cropped.

The alternative is to fit the whole 16:9 picture inside the 9:16 frame. It then occupies only the middle band, and the space above and below needs to be filled with something. Both approaches are valid. The right one depends on what the viewer needs to see.

Pick the layout per clip, not per project. A single video often needs more than one.

• Crop to the speaker. Best for talking heads, interviews and podcasts on video, where one face carries the moment. Keep headroom and eye-line, and don't crop through the chin or forehead.
• Fit with blurred background. Best when the whole frame matters: a wide product shot, a group, a chart. The picture stays complete but is smaller on screen, so text inside it may become hard to read.
• Split layout. Best for a speaker plus a screen, such as a tutorial or a webinar. The speaker sits in one part of the frame and the screen content in the other. Check that the screen text is still legible at phone size.
• Avoid stretching. Scaling a 16:9 picture to fill 9:16 distorts faces and is never a fix.

A fixed centre crop works only if the person stays centred. In interviews the active speaker changes, and in a talking-head video the speaker leans, gestures and walks. A static crop will cut them off within seconds.

There are two workable approaches. In a manual editor you add position keyframes so the crop window follows the person, which is precise but slow for many clips. With automatic reframing, the tool tracks the speaker and moves the window for you, and you review the result. Automatic tracking can still fail on fast movement, similar-looking people or crossing gestures, so review every clip rather than trusting the first pass.

When shooting new footage, you can make reframing easier by keeping the subject near the centre third of the frame and leaving space around them.

Vertical platforms overlay their own interface on the video, usually at the bottom and along the right edge. Keep captions and important text away from those areas. The caption placement advice in the TikTok captions guide applies to both TikTok and Shorts, and how long a Short can be explains the length side.

Captions should not cover the mouth or any on-screen text that carries information. If a reframe pushes the speaker's face to the lower half, move the captions up rather than letting them sit on the face.

HypeNest picks candidate moments from a long video and produces vertical drafts with captions, so you don't reframe the entire source. Paste a YouTube link or upload a file with the AI video clipper, review each vertical draft and its captions in the clip editor, and approve the ones that work.

Approved clips can be published directly to YouTube or TikTok, or exported as files for other platforms. The free plan lets you try the workflow before choosing a plan.

• The speaker's face is fully visible and has some headroom for the whole clip.
• The active speaker is in frame when they talk, not only at the start.
• Slides, charts or product shots that matter are legible at phone size.
• Captions do not cover the mouth, and stay clear of platform buttons and interface text.
• The picture is not stretched.
• You watched the final clip on a phone with the sound off.
