I have constant difficulties with long form sequences on import from a FCP XML. Either CatDV is hanging or telling me there are 'overlapping clips'.
This is a normal seq for a 50 min show with no more than 5 video and 16 audio tracks. Software like 'Sequence Clip Reporter' have no problem opening this XML and doing it in a very speedy matter too.
I know this could have a million reasons and I hope CatDV will address these problems in the future but as this is a users forum I just wanted to let people know that CatDV is not 100% yet in handling XML.
In general I'm still stunt that so few software developers pay so little attention to XML? Is the FCP XML version so fraud with problems?
I can't speak to the specific issues that you have been having, but I did have a look at the FCP XML specification (I found it via Google) because I couldn't understand how to set markers colored other than red in CatDV -- and I discovered that the FCP XML specification doesn't allow for colored markers other than red ones.
I have a sneaking suspicion that the FCP XML specification (and FCP's XML implementation) is a subset of the capabilities of the actual FCP software. That's, of course, something way out of the control of CatDV.
First off, if you're experiencing problems please make sure you're using the latest version of CatDV (currently 8.1.8, see http://www.squarebox.co.uk/download1.html). We're constanly improving the XML support and recently made some changes to handle some specific situations, such as multi-track sequences with certain kinds of dissolve transition.
Secondly, you have to remember that Final Cut Pro and CatDV are there for different purposes. CatDV is a primarily a logging and cataloging tool and only has limited editing capabilities. Things like transitions, effects and filters have no representation within CatDV, for example.
Finally, you should be aware that all the main editing applications CatDV integrates with (FCP, Avid, and Premiere Pro) all have their own idiosynchracies and bugs. For example, you can export XML from FCP and reimport it again and find that the duration of some your clips are now out by one frame, or create an XML file and send it to Premiere (which can read FCP XML files) and find it crashes if a particular tag is missing, but that Final Cut does the wrong thing if that same tag is present! We work very hard to support all these idiosynchracies, and by and large the integration is very successful.
If you're using an older version of CatDV then getting the latest update will almost certainly fix the problem with sequences that you're seeing, but if not, please mail a copy of the XML file that doesn't work to email@example.com and we'll investigate for you.
Rolf, appreciate your response and I made sure now I have the latest version and will try again. If I'm not successful I'll email you the XML.
I also appreciate your problems with the idiosynchracies of different handling of XML between apps. And yes FCP and CatDV are made for different purposes and therefor I do not expect CatDV to understand all the effects and extras that are part of the FCP XML. I just think naively that a XML has a tag for the media description and software like CatDV just extracts this tag and ignores the rest. But I'm sure it's not that easy :-)
