Posting landscape footage on TikTok? This is how to make it vertical without it going blurry

I do film commentary and all my footage is 2.35:1 widescreen — posting landscape footage on TikTok by cropping it brutally to 9:16 always loses the subtitles and the edges of the picture; adding black bars looks like a TV recording from ten years ago and people swipe away fast.

TikTok's recommendation feed is friendlier to vertical video, but creators hold plenty of landscape source. To balance "not blurry, not cropping key information, looks native", I tried three routes.

Three methods

Cropping (loses content)

Cut a 9:16 slice out of the middle of the 16:9 frame. It works for shots that are already close-ups where the background can be thrown away. Be careful with tutorials and subtitled landscape footage — the corners of a slide are simply gone.

Black bars (fast but ugly)

Scale the whole clip down into a vertical canvas with black strips above and below. Easy to implement, but it looks wrong in TikTok's dark interface, like an unfinished draft.

Blurred background fill (recommended)

Keep the original complete in the middle, scaled by width or height, and fill the space above and below (or to the sides) with a blurred copy of the original. Visually continuous, nothing cropped, no squashed faces. TwoThink Landscape to Vertical Video takes this route and processes it locally in the browser.

For the more basic comparison of the three methods, see How do you turn a TikTok video into a vertical one?.

Three parameters that matter

1. Subject position
Interview subjects often sit to one side, so align left; use centre for centred cinematic compositions. Do not let a face sit dead centre where the platform UI will cover it.

2. How much blur
Too much looks like frosted glass, too little looks like a duplicated image. Medium blur is usually the most natural; brand videos can try a low blur with a dark overlay.

3. Blurred background or solid black
A blurred background matches the colours of the original; a solid colour suits strong brand colours. For commentary I use a blurred background about 90% of the time.

Two more checks before you post

1. Size: a three-minute vertical H.264 clip at 1080×1920 can easily be 80MB or more, so Compress Video it until the upload runs smoothly.
2. Length: the first three seconds decide whether people swipe away, so cut the waffle from the intro with Trim Video first.

Xiaohongshu uses 9:16 as well, so the same vertical cut can be posted to both without making it twice.

My advice

My standard flow now is: landscape master → Landscape to Vertical Video with a blurred background → Compress Video → TikTok and Xiaohongshu. It saves time compared with cropping inside every app, and the preview matches the final file.

Try it → Open Landscape to Vertical Video with the landscape commentary clip you worry about most, and see whether the blurred background looks better than black bars.
