1. Cropping specifies the area of the video that you want to crop (remove) from the
resulting video file. You can enter values in the spin boxes provided in the
Cropping group box or drag on the control points on the preview image.
2. Keep original size resamples the cropped video so that it maintains the
specified frame size (this does produce degradation however, depending on the
amount of resampling involved). After resizing the control box you can move its
position by dragging it. (Use the slider beneath the window to preview how your
changes affect the video.)
Cropping video files
Cropping is a useful method for controlling the frame size of a video without
having to resize the actual frames. This is important as resizing frames
resamples the original video, resulting in distortion and loss of quality. The
downside though is that you need to remove data which may or may not be
important. Cropping is also good for removing unwanted noise that may
occur around the edges of a video due to bad capturing or copying.
