To convert horizontal video to vertical (16:9 to 9:16) without losing the speaker, crop a 9:16 window out of the frame and move that window so it follows whoever is talking, instead of shrinking the whole video into a letterboxed strip. You can move the crop by hand with keyframes, or use an auto-reframe tool that tracks faces and cuts to the new speaker.
Below is the crop maths, the three methods and what to do when two people share the frame.
The short answer
Don't shrink 16:9 into a 9:16 frame with black bars. Crop a vertical window (608 × 1080 from 1920 × 1080 footage, scaled to 1080 × 1920) and keep it on the speaker. Auto-reframe tools in Premiere Pro, CapCut, OpusClip or QuickVeed track faces and switch the crop when someone else talks; in any editor you can keyframe it by hand.
Key takeaways
- From 1920 × 1080 footage, a full-height 9:16 crop is only about 608 pixels wide: under a third of the frame.
- So the crop must follow the speaker, or people walk out of shot.
- Auto-reframe tools track faces; manual keyframes work in any editor.
- For two people in one shot, cut between them, or use 1:1 or a stacked layout.
Disclosure: we make QuickVeed and show how to do this in it, along with other ways. Details about other products come from their public pages, checked in October 2026 and linked at the end.
Why converting horizontal video to vertical loses the speaker
A 16:9 frame is wide; a 9:16 frame is tall. To fill a vertical screen from horizontal footage you keep the full height and a narrow slice of the width. Here is how much of the original you keep:
| Source | 9:16 crop at full height | Share of width kept | Output |
|---|---|---|---|
| 1920 × 1080 (1080p) | 608 × 1080 | about 32% | Scaled up to 1080 × 1920 |
| 3840 × 2160 (UHD) | 1215 × 2160 | about 32% | 1080 × 1920 with no upscaling |
| 1920 × 1080 to 1:1 | 1080 × 1080 | about 56% | 1080 × 1080 |
Two things follow. First, a centred crop cuts out anyone sitting off-centre, which in a two-person podcast is everyone. Second, scaling a 608-pixel-wide slice up to 1080 softens the picture, so shoot in higher resolution if you can. Our aspect ratio calculator works these numbers out for any size.
Method 1: Auto-reframe that follows the speaker
Auto-reframe tools detect faces or motion and move the crop for you. The better ones also notice who is speaking and cut to that person.
- Premiere Pro: select the sequence, then Sequence > Auto Reframe Sequence. Adobe’s guide suggests the Slower Motion setting for talking-head interviews.
- CapCut desktop: lists Auto Reframe among its AI features.
- OpusClip: reframes to 9:16 on its free plan; 1:1 and 16:9 plus moving object tracking are on Pro.
- QuickVeed: Podcast to Clips has a crop that follows whoever is speaking, using face tracking, and cuts to the new speaker.
Always watch the result. Trackers can jump to a face on a poster, lag on fast movement, or pick the listener who nods instead of the person talking.
Help the tracker before you start. Good, even lighting on faces, a background without large photos of people, and speakers who stay roughly in place all make automatic reframing more reliable. If you record a show regularly, frame each camera so the speaker sits near the centre of their own shot; then even a fixed crop works.
Method 2: Keyframe the crop by hand
This works in any editor, including free ones, and gives you full control.
- Create a vertical project: 1080 × 1920 at the same frame rate as your footage.
- Place the horizontal clip and scale it so its height fills the frame (about 178% for 1080p in a 1080 × 1920 project).
- Move it left or right so the speaker’s face sits in the centre, slightly above middle.
- At each change of speaker, cut the clip and reposition, or add a position keyframe for a smooth pan.
- Leave the top and bottom of the frame clear for captions and the platform’s buttons.
- Export as MP4 (H.264). Check sizes in our social media video size guide.
Hard cuts between speakers look more natural than slow pans in talk content. Save pans for someone walking across the frame.
Avoid cutting on every short interjection. If the listener says “right” or laughs for half a second, stay on the speaker. Cutting back and forth too often looks nervous and makes viewers lose track of who is making the point.
When two people share one shot
If both speakers sit in one wide shot, a 9:16 crop can’t hold both. Your options:
| Layout | How it works | Best for |
|---|---|---|
| Cut between speakers | Crop to whoever is talking; cut on each change | Most podcasts and interviews |
| 1:1 square | Keeps 56% of the width, often both people | Feeds (LinkedIn, Facebook) and fast back-and-forth |
| Stacked split | Two crops, one above the other | Debates; needs editor work |
| Original shape | Keep 16:9 and let the platform letterbox it | Screen shares, slides, demos |
For screen recordings, a vertical crop rarely works: the text becomes unreadable. Keep the original shape or zoom into one area at a time.
Captions, safe zones and export settings
A vertical video has more on top of it than a horizontal one: the platform’s buttons on the right, the caption and account name at the bottom, and sometimes a search bar at the top. Keep faces and captions in the middle of the frame.
- Put the speaker’s eyes roughly one third down from the top of the frame.
- Place captions in the middle third, or just below the face, not at the very bottom.
- Keep important text away from the right edge, where the like and share buttons sit.
- Leave a little headroom; tight crops that cut off the top of the head look cramped on tall screens.
| Export setting | Typical value |
|---|---|
| Resolution | 1080 × 1920 (9:16) or 1080 × 1080 (1:1) |
| Codec and container | H.264 in an MP4 file |
| Frame rate | Same as the source (24, 25, 30 or 60 fps) |
| Audio | AAC, stereo, 48 kHz |
Platforms re-encode whatever you upload, so there is little gain from huge files. Our bitrate calculator suggests a sensible size, and the platforms’ own help pages list their current limits.
Doing it in QuickVeed
In Podcast to Clips, every clip has a shape (9:16, 1:1 or original) and a crop mode: one that follows whoever is speaking, with face tracking and cuts to the new speaker, or a fixed position you choose. The same pass adds captions in one of 11 styles, the hook title for the first 4 seconds and cleaner pacing.
- Open Podcast to Clips and upload the long video (up to 3 hours). The upload keeps going if you switch to another page.
- Optionally type what the clips should be about, for example “pricing tips” or “hiring mistakes”.
- The AI transcribes the video and returns 3 to 10 moments of 15 to 90 seconds, each with a hook title, a reason it was picked and a score from 0 to 100.
- For each clip, pick the shape (9:16, 1:1 or original), a crop that follows whoever is speaking or a fixed position, and one of 11 caption styles in any language.
- Click Make all clips. Each clip gets the hook title on screen for the first 4 seconds, shorter pauses, ums and uhs removed, and your brand kit’s colour and logo.
- Download them all as a ZIP, or use Post / Schedule to send them to TikTok, YouTube, Instagram, LinkedIn and more (social posting is on the Boost and Scale plans).
Cost: the transcript is 1.5 credits a minute rounded up (45 credits for a 30-minute video, 90 for an hour), and each finished clip is 3 credits with the crop, captions, hook title and clean-up included. A 30-minute episode cut into 10 clips is 45 + 30 = 75 credits, which is exactly the 75 credits of the free 14-day trial.
QuickVeed reframes the clips it makes from a long video; it isn’t a general editor for reframing a whole film. If you need one long horizontal video turned vertical end to end, Premiere Pro’s Auto Reframe or a manual edit is the better route. For clip ideas, see how to turn a long video into YouTube Shorts.
Frequently asked questions
How do I convert a 16:9 video to 9:16 without cropping?
You can place the 16:9 video inside a 9:16 frame with bars or a blurred background, but the picture becomes small. To fill the screen you have to crop, which is why the crop should follow the speaker.
What resolution is a 9:16 vertical video?
1080 × 1920 pixels is the common size for TikTok, Reels and Shorts.
Can I convert horizontal video to vertical for free?
Yes. Any free editor, such as CapCut or DaVinci Resolve, lets you set a 1080 × 1920 project and keyframe the crop by hand.
Why does my vertical video look blurry?
A 9:16 crop from 1080p footage is only 608 pixels wide, so it gets scaled up. Shoot at a higher resolution to keep it sharp.
What about two people in one shot?
Cut between them as each speaks, use a 1:1 square, or stack two crops in a split layout.
Try it with your own video
