How do I make one video work on every platform?
You do not shoot four times. You master once, frame for the smallest crop, fix the audio to one target, then export a 16:9 cut and a 9:16 cut. Here is the exact method, with the specs that actually matter.
By Thomas, founder of CutScore · Updated June 2026
I learned this the lazy way. I shot a nice horizontal interview, exported one 16:9 file, and dropped it on YouTube, Reels and TikTok untouched. YouTube loved it. The vertical feeds did not. TikTok shrank it into a letterboxed sliver floating in a sea of black, and Reels auto-cropped it so confidently that my subject's forehead became the star of the show. Same video, three very different impressions, two of them bad.
The problem is shape. A horizontal video is wide; a phone feed is tall. When you hand a vertical platform a 16:9 file, it has two options, and you control neither. It can letterbox the whole thing, which makes your video look tiny and timid in the scroll. Or it can auto-crop to fill the frame, which means an algorithm, not you, decides what stays in shot. That algorithm does not know your subject is on the left.
So the goal is not one file. The goal is one master, framed and mixed so that re-shaping it is cheap. Get the framing and the audio right once, and the platform versions fall out of it in minutes. Here is the method I use now, after enough public embarrassment to learn it.
What each platform actually wants.
Forget the long spec sheets. These are the few numbers that decide whether your video looks native on each feed or looks like it was dumped there. Master to the left column, then crop and trim to the rest.
| Platform | Aspect ratio | What to give it |
|---|---|---|
| Master (your source) | 16:9 | 4K (3840 by 2160) so you can crop to 9:16 or 1:1 with resolution to spare. |
| YouTube (long) | 16:9 | 1080p or 4K horizontal, the full story, exported straight from the master. |
| YouTube Shorts | 9:16 | Vertical 1080 by 1920, under 60 seconds, captions clear of the UI. |
| TikTok | 9:16 | Vertical 1080 by 1920, tight cut, subject centred so nothing gets clipped. |
| Instagram Reels | 9:16 | Vertical 1080 by 1920, keep text out of the bottom-right action stack. |
| Square (feed posts) | 1:1 | 1080 by 1080 if you still post to a square feed, cropped from centre. |
| Loudness (all of them) | ≈ −14 LUFS | One target normalises cleanly across every platform, no separate mixes. |
| True peak (all of them) | ≤ −1 dBTP | Headroom that survives every platform's re-encode without crackle. |
Re-framing for three feeds means three chances to clip a face or a caption. CutScore checks each export against the platform you are posting to and flags what slipped, before anyone scrolls past it.
Master once, re-frame for the smallest crop.
1. Shoot wider than you need, and frame for the centre
The whole trick lives here. Shoot horizontal in 4K, and while you are framing, imagine a tall 9:16 rectangle standing in the middle of the shot. Keep your subject, the action and anything important inside that central column. The edges of your 16:9 frame are now disposable, room you will crop away for vertical without losing a thing. This is the single decision that makes everything downstream easy, and it costs you nothing but a little discipline at the camera. If you want the reasoning behind shooting wide and cropping in, the framing and shot choices matter as much as the resolution.
2. Cut the horizontal master first
Build your best 16:9 edit as if YouTube were the only place it would ever live. Get the story, the pacing and the colour right here, because every other version inherits from it. This is also where you fix the audio once: normalise the mix toward −14 LUFS and keep true peak at or below −1 dBTP. Do it on the master and every export carries the same clean sound. There is no platform on earth where quiet, crackly audio helps you, so this step pays off four times over.
3. Re-frame to 9:16, do not auto-crop
Duplicate the timeline, switch the sequence to vertical (1080 by 1920), and scale the footage up so it fills the tall frame. Because you shot wide and framed for the centre, your subject is already where it should be. Nudge the position shot by shot where you need to, especially in any clip where the action moved off-centre. Do not trust the platform's automatic crop to do this. It does not know which face is talking, and it loves to land on a shoulder. Two minutes of manual re-framing beats a clever crop that misses every time.
4. Move your captions and text into the vertical safe zone
Vertical feeds bury the bottom third of the frame under buttons: the like, comment, share and follow stack, plus the caption and handle. Text that sat comfortably low in your 16:9 edit will be half-hidden behind that interface on a phone. Raise your on-screen text and captions toward the middle of the vertical frame, well clear of the bottom and the right edge. The same goes for any logo or lower-third. If a viewer cannot read it without the app's buttons in the way, it is not on screen.
5. Trim the vertical cut tighter, then export all three
A vertical short is not just your horizontal video turned sideways. The vertical audience scrolls faster and rewards a tighter cut, so trim the fat: lead with the strongest moment, drop the slow setup, aim under 60 seconds for Shorts and Reels and TikTok. Then export the master at 16:9 for YouTube, the re-framed vertical at 9:16, and a 1:1 square if you still post to a feed that wants one. Three files, one shoot, and not a single auto-crop that embarrasses you.

If you only do three things.
Most of the gap between "this person posts everywhere" and "this person posts everywhere and it always looks right" comes from these three. Do them first.
By hand, by template, or in one pass.
By hand, every time
Free and total control. Duplicate the timeline, re-frame each clip, raise the captions, trim the vertical cut, export. The catch is that it is slow and easy to miss one clipped face when you are doing it on every video. Best if you only post a few.
With editor templates
Faster. Most editors have auto-reframe and aspect-ratio presets that do the first pass for you. They get you eighty percent there, but the auto-crop still misses on busy shots, and presets do not check your loudness or safe zones. You still have to inspect the result.
Checked in one pass
Hand each export to CutScore. It checks framing, caption safe zones, loudness, true peak, resolution and export settings against the platform you are posting to, and gives you a 0 to 100 score with timestamped fixes. See a sample report.
