Guides
Vertical video, with numbers
Three short guides on going from horizontal to vertical: how to crop without cutting a face, how many pixels survive 16:9 to 9:16, and why TikTok shows black bars. No filler, all the math shown.
How to crop a landscape video to vertical
The full procedure: which strip to keep, where to place the box and what to check before exporting.
Read the guide →How much you lose cropping 16:9 to 9:16
You keep 31.6% of the pixels: the strip measures 56.25% of the source height. The formula, a resolution table and when to shoot vertical instead.

Each guide answers one question and ends at the tool, not at a form. If you want the full procedure, start with the first one; if you already know how to crop and only want the pixel cost, go to the second.
Frequently asked questions
Do these guides apply to Reels and Shorts?
Yes. TikTok, Instagram Reels and YouTube Shorts share the 9:16, 1080×1920 canvas. What differs is where the interface covers content, not the ratio.
Do I need to install anything to follow the steps?
No. Everything happens in the browser with the VerCut editor: open the file, place the crop and export the MP4.
