6: Virtual Clips

src-in Speciﬁes the in point in the source clip. If this argument is unspeciﬁed,

src-in is set to the in point of the source clip.

src-out Speciﬁes the out point in the source clip. If this argument is unspeciﬁed,

src-out is calculated from the following:

• The src-in plus in/out duration if the in/out duration is speciﬁed

• The out point of the source clip if the in/out duration is not

speciﬁed

Figure 6-2 illustrates some of these arguments.

Figure 6-2 CUPS Arguments

The interval between src-in and src-out must equal the interval between in and out;

otherwise, an error is returned. If you supply only one of these intervals, CUPS

automatically makes the other interval equal to it.

Using the CUPS command repeatedly enables you to populate your virtual clip with

segments.
