Masked pre comp of clip not showing clip motion within the mask please help

Question

Hi there,
I'm trying to create a phenakistoscope Phenakistoscope - Wikipedia, the free encyclopedia out of a motion picture of a dancer.
I've transformed the clip of the dancer and precomposed it and then masked and animated the rotation of the pre comp in a new composition.  I then duplicated the now animated pre comp 20 times offsetting each one, a frame later than the last to create the wheel effect with trailing frames.
The animation of the mask and offset is working fine, however the footage in the clip is not playing in the masked composition.
please help, here is the project file. Dropbox - caropheankistope.aep
RAW FOOTAGE SAMPLE Dropbox - carolina base_raw sample.mov
NON WORKING COMP SAMPLE OUTPUT Dropbox - carolina base_sample.mov
Thanks

I'm replying to your question on my phone so I can't look at your project but I did look at your video.
Here is what I would do to troubleshoot the project. First run a RAM preview of the pre-composed and masked wedge comp. If that plays back correctly then everything else should work unless you have applied some kind of time effect to the duplicated layers. If that doesn't work then show us a screenshot of that pre-comp with all of the properties of the movie layer revealed (Press that u key twice).
If you have not sorted this out by the time I get back the office I will try and take a look at your project.
