In-Depth Information
There are three places where a strip can be selected. You can select the entire strip by right-clicking on the
middle of the strip. With the strip selected in this way, you can move the strip around the VSE editing area by
pressing the G key and moving the strip with your mouse. By right- or left-clicking the arrows at the far-right
or far-left ends of the strips, you select only those ends, as shown in
Figure 11-10
.
You can then move the ends
independently by using the G key, either truncating the sequence or extending the sequence strip. If you extend
the strip beyond the length of the original video clip, the extended portion will be composed entirely of frames
showing the last frame (if the strip is extended to the right) or the first frame (if the strip is extended to the left).
The extended portion will be colored gray, representing a duplicated still frame, as shown in
Figure 11-11
. All
three of these possible selections can also be made by pressing the B key and using a box selection method. If
the middle of a strip falls within the box area, the whole strip will be selected. If only one end of the strip is
within the box area, only that end will be selected.
When moving the full strip around the editing area, you can constrain the movement to a single channel by
pressing the G key first and then the X key. Likewise, you can press the G key first and then the Y key to con-
strain the movement to “vertical” movement from one channel to the other, without allowing the strip to slide
alongthechannels.Theseareanalogoustothex-axisandy-axisconstrainthotkeysinthe3Dspace,exceptthat

The Filter Panel
Other important operations on video strips can be carried out in the Filter panel of the Properties shelf on the
rightsideoftheSequenceEditorwindow(youcantogglethisshelfvisibleandinvisiblewiththeNkey).Inthis
panel, you can flip the image along the x- or y-axis, reverse the video in time, set a
strobe
value so that only
every
n
th frame is displayed, run the strip backward, and set several other parameters related to the video strip.
