Crop the space of a video extract only a part of it, eliminating the broths at the top, bottom, right and left . If you can specify the dimensions of the edges to be eliminated so that they can be varied, you can extract a particular shot from the video. Cropping a video can be used to eliminate the black bars that possibly surround a movie or to extract a detail of a video shot whose outline is not interesting or even to create a Gif image from the video by taking only the piece you need.
Trimming the space of a video and removing its edges is a very simple operation that can be done with one of the two best and free programs for editing videos.
You can then use the famous VirtualDub or proceed as explained in this guide with the other open source program Avidemux .

Avidemux is similar to VirtualDub and can be freely and freely downloaded from the Sourceforge website for Windows, Linux and Mac OSX .
During the installation of Avidemux you can choose the Italian language, so everything becomes simpler and more understandable. With Avidemux you can do a lot of video editing to convert them or to apply visual filters that modify their image. Among the available filters there is the Crop or Crop tool which can be used to remove the left, right edges, and then also the upper or lower space.
To crop a video, after opening AviDemux, open the video to be edited using the menu File -> Open .
If you want, you can also add more videos from the "Add" menu item (they must have the same size to be joined)
Below, where Video is written, you need to change the " Copy " item by choosing one of the available codecs, for example, MPEG-4 ASP (Xvid) .
Now click on the top menu Video -> Filters .
From the window that opens, choose the " Crop Video " filter from the Transform section by selecting it and then pressing the + button at the bottom.
The window opens the video preview and you can play with the edges to cover them.
What you are doing is cutting out part of the video and then saving the movie . For example, you can enter the value 100 at all to crop the video by eliminating a frame of the same size.
The values are immediately shown in the preview image so it becomes easy to orient yourself according to your preferences.
If the goal is to remove the black bars, you can use the auto crop button leaving the program this selection.
Click the OK button to accept the changes, see from the preview if it is all right, close and then save the video always from the File menu, assigning it a different name from the original one. As you will notice, cropping a video, it also makes it smaller, so the full screen view of the frame may be less defined.
This however is, without a doubt, one of the easiest ways to crop a video.
If the goal was to create a GIF, or an animated image, then I refer to the article on programs to create GIF from videos .
