Comskip tuning made easy

[groover km]

Reboot's ini file is on erik's forum.

I do not see the graphs in the debug window, all I see is the timeline. Pressing "G" key toggles between brighter and darker image. Is there a trick to getting the graphs?

Also, I'm dropping the .txt file on a desktop shortcut to comskip.

No graphs when dropping the .txt file, because the info is in the .csv file and with a .txt file dropped its not available/read.
If you want the graphs drop the .csv file, or see them appear during processing of the .mpg when using the -w switch

I only had one problem where RTL4 starts CSI systematically much later than programmed. The show before is in 16:9 which makes comskip pick the wrong place for the logo. Still no scenes were marked as ads but the ads were detected incomplete.

Which version do you run?
I added special processing for this case that is supposed to solve it.

Cool, thanks. When dropping the .csv file, can I still edit the .txt file cutpoints? (just can't wait to get home and try it)

Symply cutting out part of the show and have comskip write the correct logo, putting this logo in the GBPVR directory and calling it trough the parallelprocessing.bat (comskip --logo=csi.txt %1) file for RTL4 shows makes the detection accurate to the last frame.

This is something I never tried but assumed it would work.

Good for other users to remember.
You can have comskip learn a logo and then reuse the learned logo to have very robust logo processing without the chance of having a wrong logo learned.

No, because when you are editing you are interrested in the video and not in the analysis Comskip made. (my opinion)

I don't ever record anything on news and info stations, and have separate ini's for spike and cbs.

Could you post your settings for spike and cbs. I have the same issues with Spike.

Parallelprocessing.bat
Notice how the different .ini's are called
Also notice the line right after renamerecordings. This renames the _original file back to the truly original name that gbpvr gives it. This allows for manual editing using videoredo, if the automated clean file is wrong (very seldom).
Also notice the transcoding section at the end (temporarily disabled).

Code:

@echo off
Rem ParallelProcessing.bat
Rem This script will be run automatically by GBPVR when found after a recording is finished
Rem To enable it put this file inside your GBPVR default program directory (C:\Program Files\devnz\gbpvr\)
Rem together with Comskip.exe, Comskip.ini and Comskip.dictionary
Rem The script is called with two parameters
Rem %1 is the fully qualified name of the recorded mpeg file.
Rem %2 is the channel number of the recording
echo Prostprocessing.bat invoked on %1 recorded from channel %2 >>postprocessing.log

Rem The part below can be used to not run Comskip on certain channels, please modify for your conveniance.
Rem The channel numbers that should be skipped are the numbers between the double quotes ("").
Rem You can add "if" lines as much as you want
Rem To disable this behaviour use channel numbers outside the normal range, put a "rem" before the "if" or delete the "if" lines

Rem list of channels to not run comskip on
Rem if "%2" == "27" goto eof:
Rem if "%2" == "36" goto eof:

Rem this trick also makes it possible to have dedicated comskip.ini file for certain channels.
if "%2" == "7" goto channel7:
REM if "%2" == "4" goto channel7:
REM if "%2" == "6" goto channel7:
if "%2" == "15" goto channel15:

Rem use the default comskip.ini for all other channels
goto generic:

:channel7
comskip --ini=comskipcbs7.ini %1
goto continue:
:channel15
comskip --ini=comskipshcase15.ini %1
goto continue:

:generic
Rem The actual run of Comskip. Only one parameter, the name of the mpeg file to process.
Rem Comskip will read its settings from the Comskip.ini found in the same directory as Comskip.exe
Rem Both are supposed to be in the GBPVR default program directory. (C:\Program Files\devnz\gbpvr\)
comskip %1
:continue

Rem Once the commercials have been identified you can run comclean to delete the commercials from the recording.
Rem Do this only when you are not using the Skip function in the GBPVR viewer.
REM the following calls videoredo to edit the file, then renamerecordings.
cscript //nologo "C:\Program Files\VideoReDoPlus\vp.vbs" "%~dpn1.VPrj" "%~dpn1_Cleaned.mpg" /t1 /q
Rem RENAME the old .mpg file and rename the new one to the old name
move "%~dpn1.mpg" "%~dpn1_original.mpg"
move "%~dpn1_cleaned.mpg" "%~dpn1.mpg"

RenameRecordings -t %1 > renamerecordings.log
move "%~dpn1_original.mpg" "%~dpn1.mpg"

REM Testing mencoder section------------------
REM This is the transcoding portion
REM cd "C:\Program Files\devnz\gbpvr\"
REM start /min /low mTranscode_0p0p3.vbs
REM end mencoder test section ------------------

[bobrap]

I'm using these ini files with great success...thank you very much. If I have a channel that I don't run comclean on (ex. Encore), how do I set it up to run renamerecording so I have the show and/or episode name? Plus, is the original name format (Combat!_20060214_08000900.mpg) hard coded? Thanks for any help
