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
