Comskip: Interpreting the aspects file

[zehd]

I'm setting up ZProcess to read an aspects file to help decide some cropping...

I have many shows that are 4x3 but the program is letterboxed. I want to crop the 4x3 letterbox to 16:9.

After activating the output_aspect=1 I get aspects files.

How can I determine the main aspect ratio for the main program, not commercials.

Maybe comskip does not already detect letterbox inside a 4x3...

Here's a sample from mythbusters

Code:

0:00:00.03  720x 480 1.90 minX=   1, minY=  54, maxX= 720, maxY= 422
0:00:00.06  720x 480 1.96 minX=   1, minY=  54, maxX= 720, maxY= 422
0:03:50.59  720x 480 1.51 minX=   1, minY=   1, maxX= 720, maxY= 480
0:04:02.24  720x 480 1.96 minX=   1, minY=  54, maxX= 720, maxY= 422
0:04:07.74  720x 480 2.22 minX=   1, minY=  82, maxX= 720, maxY= 398
0:04:11.05  720x 480 1.96 minX=   1, minY=  54, maxX= 720, maxY= 422
0:14:39.67  720x 480 2.17 minX=   1, minY=  74, maxX= 720, maxY= 406
0:14:41.11  720x 480 2.22 minX=   1, minY=  82, maxX= 720, maxY= 402
0:14:42.91  720x 480 1.51 minX=   1, minY=   1, maxX= 720, maxY= 480
0:18:42.65  720x 480 2.22 minX=   1, minY=  82, maxX= 720, maxY= 402
0:18:45.89  720x 480 1.96 minX=   1, minY=  54, maxX= 720, maxY= 422
0:25:36.80  720x 480 2.17 minX=   1, minY=  78, maxX= 720, maxY= 406
0:25:38.40  720x 480 2.22 minX=   1, minY=  82, maxX= 720, maxY= 402
0:25:39.57  720x 480 1.96 minX=   1, minY=  58, maxX= 720, maxY= 418
0:26:10.50  720x 480 1.51 minX=   1, minY=   1, maxX= 720, maxY= 480
