Help! AAF seq won't open, says has 50+ audio trax

Paul,

My apologies, we had a bit of a problem this morning with your XML in the lab this morning.
I am able to import it into FCP X and run a conversion on it with X2Pro- obviously without the media.

Let me explain a few things which will help understand why there are so many tracks in your AAF from your test and what we can do to help with that, if you require less.
Just for your reference, most of this information is found in our KnowledgeBase under the "How It Works- Laying out Tracks" section on our website. http://x2pro.net/help/knowledge-base

Final Cut Pro X uses the magnetic timeline in order to layout a project, while within AAF a composition is constructed from a number of fixed tracks.
In AAF, each track is a single (mono) channel of audio.
The first thing that X2Pro does is to group and sort everything by its role within the Final Cut Pro X project.
This results in tracks in the AAF file also being grouped by role, typically dialogue first, then effects and music.
There are options for the user to be able to create their own role order, ignore some roles entirely, and to ignore subroles when laying out the tracks so that all the subroles of one role will be packed onto as few tracks as possible (this feature is not available in X2ProLE).

Within each role, X2Pro analyses the Final Cut project and places the clips on tracks in a logical fashion, usually creating several tracks in the AAF file from each role.
Final Cut Pro project components will be rearranged during the conversion process:

Multi-channel clips will be split into separate mono components, each placed on a separate track;

Clips that overlap (for example J/L Cuts) will be put on between different tracks;

Composite clips will be separated into their component clips;

Multicam clips will be reduced to the selected angle;

In these cases, where necessary, extra tracks are created in the AAF file, so the AAF file will often contain many more tracks than the Final Cut Pro X project appeared to have.
Each track will contain clips from just one role and will be named accordingly, for example "A24 (effects)".

Please let us know if you have any questions after reading this or if you need any further assistance.

Hi Paul,

Yes we can convert the xml to an AAF if we force it here without the essence, and it does show 57 channels, there is one retiming that is applied.

However as there didn't seem to be much happening when we looked at it in ProTools, we tried to import the XML back into FCP and it would appear its invalid, and it cannot be loaded.

Can you confirm your end and try to re-import the XML

Yours Sincerely

Hi, urgent help required please!

From the attached FCPX XML I made an AAF. The media carried over fine but the sequence wouldn't open, saying it had more than 50 audio tracks - very odd as no clips in the FCPX sequence have more than 2 or 3 and there's never more than 6 layers of audio going on at any one time.

This is all going critical as I'm fast approaching audio mixing stage but, so far, without any audio.

All help, questions and suggestions gratefully received!

With many thanks, Paul
