I know that Matroska does have a way to remove the border by editing its metadata, and i also know that Webm is a cheaper version of Matroska. I have tried using MKVtools to edit Webm and it appears to work, but then when i play the file nothing changes.

So does Webm support metadata removal of border from the video? If it does what tool can i use to perform this task?


See here https://www.webmproject.org/docs/container/ under section Track. There you find PixelCropBottom, PixelCropTop, PixelCropLeft and PixelCropRight - all of which are supported. These parameters should do what you want. They also exist for Matroska.

Look for a tool that can manipulate those parameters.

  • -vf will still reencode the video stream, will it not? – v010dya Sep 11 at 8:21
  • Yes. I'll edit my answer and remove it. I've no other idea what tool to use at the moment. – Matt Sep 11 at 8:32
  • Thanks. I have checked it, and MKVtools can do that, and i guess i've been doing that.... however, the players simply do not respect that those parameters. – v010dya Sep 11 at 8:33
  • If you use a browser, like Chrome, and open the webm video there, does it work then? Maybe some or many players have not implemented this feature as it is probably not used much. – Matt Sep 11 at 8:39
  • Yeah, I currently use SeaMonkey, and it works there, but only if i put not only crop values, but also display values. – v010dya Sep 11 at 8:41
