Remove black bars from videos

Burned-in bars at the top and bottom or left and right cost picture area – and twice as much in portrait. Here is how to get rid of them without measuring by hand.

Black bars appear when a video was put into a different format than it was shot in: a cinema format inside a 16:9 video (bars at the top and bottom), a phone video inside a landscape frame (bars on the left and right), or an export that only padded a format instead of cropping it.

The bars are then part of the picture. If you crop such a video for portrait, they end up in the crop – and the platform may add its own bars around it as well.

Before with bars, after without

Why they hurt twice in portrait

Less picture

A cinema-format video with bars uses only part of the height. Even less of it remains in a portrait crop.

Wrong crop

A crop that includes the bars is no longer centred on the picture but on picture plus black – the subject sits too small and too high or too low.

How FrameJet removes the bars

  • When you upload, FrameJet checks each edge of the frame on its own and detects bars at the top, bottom, left and right – even if they are not pure black.
  • Detection looks at the whole video, not just the first frame. A dark opening does not mislead it.
  • Before exporting, you see what was detected and which picture size remains. You can switch it off with “Remove bars” if needed.
  • Then you place the crop for each format on the actual picture. How that works is explained under Landscape to portrait.

And without FrameJet?

Any editing program lets you crop bars away by hand: measure the edges, set the crop, export. It works, but takes a separate pass for every video and every format – and a sharp eye when the bars are not completely black.

Frequently asked questions

Does FrameJet detect bars that are not completely black?

Yes. Each edge of the frame is checked on its own; dark grey or slightly noisy bars are detected too. You see what was detected before exporting.

What happens with a video that starts dark?

Detection looks at the whole video, not just the first frame. A dark scene at the start is not mistaken for a bar.

Can I switch off bar removal?

Yes, with the “Remove bars” switch in the editor. The picture then stays as it is.

Does removing the bars make the video worse?

No. Only the black border is removed; the picture itself stays as it is and is the starting point for every crop.
