Hi Helena,
so glad you asked ;-). For starters, these two seem to be somewhat
redundant is applied to subclips:
startoffset
Description An integer specifying the offset in frames from the
start media value, calculated
using the In point of the clip from which the subclip was created.
Parents subclipinfo, clip, clipitem
This is used for subclips
vs.
mediadelay
Description Integer specifying the starting offset (in frames) for a
clipitem used in a multiclip
or subclip.
Parents clipitem
this is used for multiclips. This value could even be negative.
Also, if you could shed some light on how the various Durations,
Ins, Outs, Starts and Ends (for clips, clipitems, files) interact
with eachother that would be fantastic.
if the media and the sequence are the same framebase and no speed
effect has been applied then
duration = out-in = end-start.
Start and end indicate when on the enclosing sequence a clipitem
starts and ends.
In and out indicate the portion of the given piece of media a specific
clipitem represents.
I've tried to diagram out the terms and their meanings here:
Attachment:
pastedGraphic.pdf
Description: Adobe PDF document
Note that in/out/inoffset/outoffset are all in the framebase of the
media, and duration/start/end are in the framebase of the sequence.
I purposely made the clipitems (the one in the media portion then the
one in the sequence portion) different sizes. These could be the same
item, just with a framerate conversion between them or a speed effect
of some sort, such that out-in !=duration.
I hope that helps.
Cheers,
Helena

Hi Rainer,
That document is indeed all the documentation for the XML format.
There is also a few sample applications, but I dont think there's
anything special about the durations in those.
What was your specific question about durations in the XML for
Final Cut Pro?
Cheers,
Helena

Hello,
besides the document "Final Cut Pro XML Interchange Format", is
there any information out there about how durations etc are
treated in XMLs out of FCP 6?
Thanks,
Rainer
