Vertical video from an action camera

Why this is a real question

Action cameras were designed around a horizontal frame, and almost everything about them assumes it: the mount sits under a landscape body, the screen is landscape, the field of view is wide rather than tall. Meanwhile most of the footage people shoot now gets watched on a phone held upright.

The result is a lot of vertical video that was cropped out of the middle of a horizontal clip — which means the subject is cut off at the sides, the resolution is a third of what was recorded, and the wide angle that made the shot interesting has been thrown away. There are better options, and they are mostly free.

The three methods, and what each costs

1. Rotate the camera and shoot native 9:16. Turn the camera 90 degrees on its mount. Current cameras detect the orientation and write a genuine vertical file; stabilization and horizon lock keep working, and you use the full height of the sensor. This is the method that loses nothing, and it is the right default if you know in advance that the clip is for a phone.

The one real catch is mounting. A GoPro-standard two-prong mount under a rotated camera puts the body sideways on the harness or the bar, which can foul a strap, block a button, or sit at an awkward angle on a clamp. GoPro and DJI both sell vertical mounting buckles for exactly this, and a 1/4-20 thread plus a small ball head solves it generically. Check the fit before the day, not at the trailhead — the mount compatibility map is in what actually fits what.

2. Shoot wide or 4:3 and crop in the edit. The compromise method, and a good one when you do not know yet where the clip is going. A 4:3 or full-sensor mode records a taller frame than 16:9, so the vertical crop out of it keeps more pixels and more of the subject's head and feet. You still lose width, but you lose less, and you keep the option of a horizontal cut from the same file.

3. Reframe a 360 recording. The only method with no trade-off at all. A 360 camera records a sphere; the vertical cut and the horizontal cut are both just choices you make afterwards in the app, at full quality, from one recording. For anyone who genuinely needs both aspect ratios from the same day, this is the honest answer — and it is one of the stronger arguments for the format. The cost is the reframing pass, which is real work per clip: 360 camera vs action camera sets out the trade, and how to edit on a phone covers doing it on a handset.

Settings for vertical, specifically

Use linear or wide, not the widest field of view. In a tall narrow frame the widest setting bends the vertical edges noticeably, which looks far worse than the same distortion does in a horizontal frame. Linear is the flattering choice for vertical.

Keep horizon lock on. This matters more in vertical than in horizontal, because a tall frame exaggerates roll. A few degrees of tilt that would pass unnoticed in 16:9 is obvious in 9:16.

4K is plenty; frame rate beats resolution. A vertical clip on a phone is watched at a fraction of 4K. Spend the bitrate on 60 frames per second instead so you have clean half-speed, which is most of what short vertical video does with motion.

Get closer, and frame higher. A vertical frame has almost no room sideways and a lot of room up and down. That changes composition: subjects need to be nearer, and the interesting part of the frame is usually the top two-thirds, because the bottom is where phone interfaces put buttons and captions.

Leave the bottom fifth of the frame boring. Every platform overlays something there. Keep faces, horizons and the subject out of it.

Where vertical genuinely works, and where it does not

It works for anything tall and close. A person, a climb, a waterfall, a bike on a steep descent, a paddle entering water right in front of the lens. Vertical framing is flattering to height and to proximity, and action cameras are very good at proximity.

It works for selfie-style and chest-mounted shots. A chest-mounted camera in portrait frames your hands and the trail ahead in a way that reads naturally on a phone. The flip screen on the Insta360 Ace Pro 2 in our picks is a real advantage here, because framing a vertical self-shot blind is guesswork.

It does not work for landscape. A lake, a ridge line, a wide beach — the thing that makes those shots is width, and vertical removes it. Shoot those horizontally and accept that they are for a different edit.

It does not work for anything you will want on a television. A 9:16 clip on a TV is a small strip with black bars either side, and there is no fixing it after the fact. If the footage is a family record rather than a post, shoot horizontal.

The practical workflow if you want both

Most people do not want to choose. The approach that works without doubling the shooting:

Shoot the day horizontally in a tall mode — 4:3 or the camera's full-sensor option — so there is vertical crop room in every clip. Then build the vertical edit first, because it is the harder constraint, and derive the horizontal version from the same selects afterwards. Doing it the other way round means re-cutting everything.

Or shoot 360 and stop thinking about it. One recording, two aspect ratios, full quality in both, at the cost of a reframing pass. For somebody posting regularly that trade usually comes out ahead, which is why the Insta360 X5 is first in our picks on this page rather than a flat camera.

Either way, decide the aspect ratio before you start assembling a timeline. Changing it halfway is the single most frustrating job in video editing, on a phone or anywhere else.
