I have a ini I used for Comcast from someone else that is fairly good, however I have issues probably rightly so, with commercials that contain the channel logo. Is there ways around this? Usually the commercial or two before the show comes back on frequently it keeps them with the logo and are usually channel specific advertisement for shows. Not sure if there are ways to deal with this?

Perhaps if you experiment with the value of:
shrink_logo=5 ; Reduce the duration of the logo with this amount of seconds

Or you can set
logo_present_modifier=1
to cancel the impact of logo on commercials.
if the logo stay's on during the transition from show -> commercial or reverse you better disable logo in the methods

Negative values in ini parameters is a bit of a problem......
Will consider

Thanks for the replies. What does shrink logo do? I know the logos on the commercials are the same as the show as I was thinking that meant there was some variance in the logo type in commercials vs the show?

Also what does logo present modifier actually do? I know erik you mentioned cancel the impact of logos on commercials, but how is that different than including or not including logos in the detect method?

I also see a number of situations where comskip will remove nothing. Unfortunately I have no logs left as my methods are, comskip, then use output with videoredo to create a new file and then delete temp files from comskip. I end up with new files occasionally that are the full length of the original so not sure why it occasionally completely fails but what you gonna do.

Also is there any logic that makes sense around the beginning and end of a show? So show starts, first two minutes are garbage as I have my DVR set to record two minutes early if it can. Occasionally comskip will remove the beginning and end. Rarely. My though is once you've hit the start of the show, maybe where it finds the logo, everything before it should be removed. Then whatever the last commercial was, everything after it should be removed. May not be that easy but I know the first two minutes for me are always garbage and it's usually still there so figured when the start of the show is detected remove everything before it.

Thanks.

Did you read the tuning guide inside the distribution zip file?

Actually reading thru it last night. So for starters, does

delete_show_after_last_commercial=1

Apply to if I add an extra 5 minutes to the end of my shows AND there is actually the start of the next show as part of it? And how will this react since the setting is "Go over 5 minutes WHEN YOU CAN". So if I have 4 tuners and always recording 4 shows, it won't add the extra 5 minutes as wen it is done, has to move onto something else. Most of the time it does, but for some reason with one of my families soap operas, I guess it won't record two shows on the same channel at the same time. So if a show is from 11:30 - 12:30 on ABC and then 12:30-1 on ABC, it will stop the prior show at 12:30 even though 3 other tuners are available.

Thanks.

shrink logo reduces the duration of logo being present at both start and disappearing of the logo
All modifiers change the block score. Above 1 means commercial, below means show
