Catchups can start at a specific strip by using the index syntax, see

.B INDEX SYNTAX
and

the traversal ends at the first existing image file when starting from

at a certain strip. The index can be specified by appending a colon \fB:\fP
and the index name after the module. Multiple comma-spearated indices can
also be specified.

a strip, eg. a number or a date. The expected format is documented when using
the \fB\-\-modulehelp\fP option.
