Cropping Media Files

Illustrated below is a section of the timeline.

Elements of the Timeline

Where
1 - Link option corresponding to every track.
2 - Seek Slider
3 - Start selection slider
4 - End selection slider

All editing operations like cut, delete, copy, crop and split work on linked tracks only (tracks that have the link option enabled).

Linked and Unlinked Tracks

In the above screen-shot, Video 1 and Audio 2 tracks can be edited while Video 2 and Audio 1 tracks cannot. This is because these tracks are not linked (shown highlighted).

There are two types of crop operations possible in Video Edit Magic.
1. Crop and
2. Crop Sources.

Before Crop or Crop Source(s)

After Crop

After Crop Source(s)

Crop operation will keep the selected sources (selection sliders not visible) or range (selection sliders visible) in a track and delete the rest. Crop does not work across tracks. If a particular track is unlinked or locked, then crop will not affect that track.

Crop Source operation is available only when selection sliders are visible. Unlike crop, that deletes everything other than the selection, Crop Sources crops only the sources that lie in the selection range (between the selection sliders).
