How to use Avi Clipper
Choose the Clip tab.
Use the Select button, then specify the source video.
Set the beginning and end points of your clip.
The length and size of the clip can be seen on the bottom line of the interface. The resulting file may be slightly larger depending on the availability of key frames.
Use the Start button to make the clip.
If you need to stop work before you have finished making your clip, use the save button to save your settings as an Avisplit project file.
