Read a file with transform information for each frame and

apply/compensate them. Together with the @ref{vidstabdetect}
|

filter this can be used to deshake videos. See also
|

@url{http://public.hronopik.de/vid.stab}. It is important to also use

the unsharp filter, see below.

To enable compilation of this filter you need to configure FFmpeg with

@code{--enable-libvidstab}.

(default: 10). For example a number of 10 means that 21 frames are used
|

(10 in the past and 10 in the future) to smoothen the motion in the

video. A larger values leads to a smoother video, but limits the
