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:
- Set the starting point with the In pointer button. You
will see a left hand bracket on the timebar.
- Move your cursor to the ending point of the clip you want
- Set the ending point with the Out pointer right hand
- You will see a colored bar inside the brackets for easier
- 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.
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.
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:
- Arm only tracks to change.
- Define the destination region on the timeline with [ and
], the In and Out points.
- You can achieve maximum precision by setting the active
region in the zoom panel.
- Define the clip you want to use in the viewer with [ and
], the In and Out points.
- 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.
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.
The copy icon, or shortcut letter “c”,
copies the selection into the copy buffer.
