XSLT looks like a good choice for this problem (of course you can do this in
Perl as well by parsing the documents and processing the document trees in
Perl).
I would recommend the following approach: Use the second document (scenes)
as your primary document, process each scene in sequence and pull in shot
information from the other file using the document() function, something
like
<xsl:copy-of select="document('shots.xml')/video/shot[@id = $thisid]" />
