I created a video to demonstrate how to do something in OneNote, and now I need to insert it in my reference app. The video fills my entire screen, which isn't optimal for my app because only 165x110 pixels are actually involved in the video - the rest is a blank white background. Now, I need to find out how to crop this video down to the essential pixel size. If this cannot be done, I could create a .gif, but I would prefer to just crop my video.

Any decent video editor would have this feature.

E.g. you can use VirtualDub:

  • Free and open-source
  • Runs on Windows
  • Has a GUI.
  • Can crop

  • I really like this, especially the way I could just run it without an installation. Unfortunately, I need to convert my .mp4 to a .mpeg now.

If you prefer using a CLI, you can use FFmpeg:

  • Free and open-source
  • Runs on Windows
  • Allows to crop: ffmpeg -i in.mp4 -filter:v "crop=out_w:out_h:x:y" out.mp4
  • Is CLI so you can batch.

    There is very little I haven't managed to do with ffmpeg. The learning curve is pretty steep, but it's very much worth learning if you do lots of video editing.

XMediaRecode will do this for you. It is a video and audio transcoding program that works on Windows. It also supports a lot of different file types such as WMV, MP4, MP3, 3GP, Matroska and more. Additionally it has a GUI and is Freeware. Image of XMediaRecode cropping MrMaker

If you have issues installing the proper codec on VirtualDub, you can use Avidemux:

  • free and open source
  • binaries for win32/win64
  • Go to Video > Filters > Crop
