Final Cut Pro 7 XML Adapter

[jminor]

OTIO needs support for reading & writing FCPXML files.

There are two different versions of the Final Cut XML format in use:

First implementation submitted. After a round-trip of a simple file through otio, some things were missing

• colors on markers
• transition
• resolution of the sequence. Premiere was not able to figure this out from the content on the timeline, as such the new sequence was cropped
• linking information between audio and video track

This link was used as reference for implementation:
https://developer.apple.com/library/content/documentation/AppleApplications/Reference/FinalCutPro_XML/Elements/Elements.html#//apple_ref/doc/uid/TP30001156-TPXREF105

If I understand it correctly, then mandatory sub-elements are marked by a +. But I had to add some other sub-elements in places, otherwise premiere was not able to read my file.

• clipitem also needed file
• clip also needed media/audio/track/clipitem and media/video/track/clipitem.
• clip/file also needed media/audio and media/video

The first version (for alpha 3) will not include transitions.
