Thanks for confirming that. Yes, we already insert a comment in the
XML file that we export, but that doesn't help us much as we're
unlikely to be re-loading these files into our app.
Currently we artificially extend the duration of exported clips so
they have the expected duration when imported into Final Cut Pro, but
I don't know if that's a sensible strategy or not. We don't do any
correction on import. That means if we import a Final Cut XML file we
display it the same way as it was when it was exported, but not the
same way as it would be if you import it into Final Cut Pro.

Hi Rolf
I saw that error as well.
For own usage I fix that internally and do insert a comment at the
beginning of the XML, which tells me who did create it - my app (or
Automatic Duck, as Wes includes a comment as well) or another one -
in case there is no comment.
I think it's a good idea for any developer to insert a comment at
the root level of the XML.
With the next releases of some of my apps I also will put an extra
XML into the comment, which will allow others to parse version
changes and handling of some nodes.
This doesn't help really much in case Apple or other other companies
you don't know about will fix or create bugs, but at least it keeps
people who read your comments informed about what you are doing.
To make it even more complicated be aware there are 3 versions of
XML V1 out which are not really compatible "up-down" with the
versions of FCP 4.1 thru 5.x

Ok, here's another question then.
When FCP imports an XML file describing subclips, it ignores the
clip's stated duration but calculates it based on the file's
duration and startoffset and endoffset. However, there seems to be
a bug in FCP 5.0.4 and the processing of endoffset is out by one,
so the subclip's duration (and Media End) is one frame too short
after it's imported.
You can see this by importing a subclip, exporting it and importing
it again. Each time it gets shorter by one frame, which I take it
to mean it's unequivocally a bug in Final Cut Pro, and not my
understanding of the XML format :-)
Has anyone else seen this? If so, how do you handle it? Do you
process subclips the same (broken) way as Final Cut, to try to be
compatible, or do it correctly and put up with durations being out
by one frame compared to FCP? Obviously the danger with trying to
correct for FCP's behaviour is that Apple might fix it in a future
update.
