Two Screen Editing

This is a fast way to construct a program out of movie files (in other programs is called three points editing). The idea consists of viewing a movie file in one window and viewing the program in another window. Subsections of the movie file are defined in the viewer window and transferred to the end of the program in the program window. Two screen editing can be done simply by using keyboard shortcuts. To get familiar with which keys to use, move the mouse pointer over the transport panel and a tooltip appears, showing what key is bound to that button.

To begin a two screen editing session, load your media resources by using the main menu File pulldown and choose Load files ; make sure the insertion mode is set to Create new resources only. This insertion strategy is to ensure that the timeline stays unchanged while new resources are brought in. Go to the Resources window and select the Media folder. The newly loaded resources will appear. Double click on a resource or drag it from the media side of the window over to the Viewer window .

Check to make sure there are enough armed tracks on the timeline to put the subsections of source material that you want. Usually this would be one video track and two audio tracks, but if there are not enough, just create new tracks or arm more tracks.

Now to start your 2 screen editing, in the viewer window, define a clip from the media file:

1. Set the starting point with the In pointer button. You will see a left hand bracket on the timebar.
2. Move your cursor to the ending point of the clip you want to use.
3. Set the ending point with the Out pointer right hand bracket.
4. You will see a colored bar inside the brackets for easier viewing.
5. Drag the In/Out point with the mouse to conveniently change their position.

These In/Out points define a clip . You can now use this in a couple of different ways.

####
Splice

The splice icon, or shortcut letter “v”, inserts the selected area in the timeline after the insertion point. After the splice has taken effect, the insertion point moves to the end of the edit ready to be used as the next splice location. This way you can continuously build up the program by splicing. If an In point or an Out point exists on the timeline the clip is inserted after the In point or after the Out point. If both In and Out points are set on the timeline, the clip is inserted after the In point. If there are edits after your chosen splice location on the timeline, they will be moved to the right.

####
Overwrite

The overwrite icon, or shortcut letter “b”, overwrites the region of the timeline after the insertion point with the clip. If an In point or an Out point exists on the timeline the clip is overwritten after the In point or after the Out point. If both In and Out points are set on the timeline, the clip is inserted after the In point. If a region is highlighted or both In and Out points exist they limit the region of the overwriting and the clip may therefore be shortened. Here is a detailed explanation to take advantage of this method.

To overwrite exactly on a precise region of the timeline:

1. Arm only tracks to change.
2. Define the destination region on the timeline with [ and ], the In and Out points.
3. You can achieve maximum precision by setting the active region in the zoom panel.
4. Define the clip you want to use in the viewer with [ and ], the In and Out points.
5. Overwrite from Viewer to the timeline.

If the destination region is shorter than the clip defined in the viewer, the portion of the clip longer than the destination region won't be inserted and on the timeline the following edits won't move. If the destination region is longer than the clip defined in the viewer, the destination region will shrink and on the timeline the following edits will move to the left.

#### Clip

The clip icon, or shortcut letter “i”, generates a new clip for the resource window containing the affected region but does not change the timeline. Every clip has an optional/default title and description.

#### Copy

The copy icon, or shortcut letter “c”, copies the selection into the copy buffer.
