I'm brand new to Comskip, but have been using SageTv for awhile. I'm using Comskip as a free-standing program, initiated on the command line.
My question is about the commerical list generated in the log file. The 'initial' list is just about right, but for some reason (unknown to me) the 'final' list excludes some of the commercials that were correctly detected.
For example, I've tried these three detection methods, and always get exactly the same result:

1) Black Frame
2) Logo - Give up after 1200 seconds
3) Scene Change
4) Aspect Ratio

Initial Commercial List

3) 71360 80483 0: 5:4.40
4) 94166 103420 0: 5:8.78
5) 108463 109655 0: 0:39.77

Final Commercial List
---------------------
1 - start: 9961 end: 14042 [ 2: 7] length: 0: 2:16.17
2 - start: 27133 end: 34115 [ 9: 19] length: 0: 3:52.97
3 - start: 49033 end: 53610 [ 22: 27] length: 0: 2:32.72
4 - start: 108463 end: 109655 [ 50: 51] length: 0: 0:39.77
The two ~ 5 minute commercials in the second half of the show are being filtered out when the final cut list is generated.
Any thoughts why? What happens to the list between initial and final?
thanks

Re: Initial vs Final Commerical List?
I'm running into a similar problem. The initial commercial list is accurate but after weighing no commercials are found. How can I stick with the initial commercial list?
