How to remove commercials in AVI files using ComSkip

Tools Required
VirtualDub 1.6.12 http://www.virtualdub.org/
QuEnc 0.61 http://nic.dnsalias.com/QuEnc.html
ComSkip 0.79.30 or higher http://mk.kaashoek.com/comskip/
AVISynth 2.5 or higherhttp://www.avisynth.com
MEncoder (optional) http://www.mplayerhq.hu/

Those of us who capture television programs directly to AVI files (not MPEG files) have had to watch from the sidelines while ComSkip worked its magic for everyone else. To get around this problem, I have devised a method for detecting commercials in AVI files and removing them.

Please note that I don't go into detailed explanations of explicitly setting out folders, or explaining how to create and run batch files. I am merely providing the framework for going about the process.

Step 1 - Convert to MPEG
There are a number of programs out there that will covert an AVI file to an MPEG file. I have found QuEnc to be useful. QuEnc can be run using the command line and gives good quality conversions in a relatively short time. For example, the follwing command executed in a DOS window has given me sufficient quality in a short time:

Code:

quenc.exe -i capture.avs -o capture.mpg -b 3000 -aspectratio 4:3 -mpeg1 -novbr -auto -nohq -priority 4 -close

Before running the above command, create a file called "capture.avs" file with the following command:

Code:

AVISource(capture.avi)

Note: Don't use 0.70. It doesn't work for me for some reason.

Step 2 - Run Comskip (0.79.22 or higher)
Now run ComSkip on the MPEG file you created in step 1.

Code:

comskip.exe capture.mpg

If you want to use VirtualDub make sure that you change the following line in the comskip.ini file from

Code:

output_vcf=0

to

Code:

output_vcf=1

Step 3 - Apply Commercial Cuts to AVI file

Using VirtualDub (1.6.12 or higher)

Use the following three commands from a command prompt to make the cuts using VirtualDub.

Code:

vdub.exe /c

vdub.exe /s capture.vcf /p capture.avi capturecut.avi

vdub.exe /r

where capture.vcf was created by comskip, capturecut.avi is the new file created by VirtualDub.

Why am I wasting your time with all this command line nonsense? Because command line based programs allow us to make batch files to automate the process. Below are example batch files that you need to modify to match your own desired directories. The resulting files in the CUTDIR folder are in the same format as the capture format. The total processing time is about 20-25 minutes for an hour of programs on an AMD 2400.

Example Batch File 1 - Basic
This batch file is a basic setup for using the above method for your own system. Modify the initial variables to match your directories.

Code:

setlocal
REM The variables below need to be changed to match your setup
REM Please don't change the presence or absence of quotation marks as it may interfere with the functionality of the batch file

set CAPDIR=X:\DigitalVCR\temp
REM Set the directory where the original AVI files are captured

set CAPDIRBACKUP=X:\DigitalVCR\temp3
REM Set the directory where the original AVI files are backed up

set CUTDIR=X:\DigitalVCR\converted
REM Set the directory where the cut versions of the original AVI files are placed

set COMSKIP="C:\Program Files\ComSkip\comskip.exe"
set VDUB="C:\Program Files\VirtualDub\vdub.exe"
set QUENC="C:\Program Files\QuEnc\QuEnc.exe"
REM Set Program Locations

REM Create VirtualDub script
REM You can add additional lines to add video or audio processing to the vcf script file.
REM If you are going to add Video processing of the file you need to add the line "VirtualDub.video.SetMode(1);" before your video processing commands.

Example Batch File 2 - Adding AVISynth commands and VirtualDub to the processing.

Hi,

My tv card capture on mpg.

I try to follow the tutorial but when I do:

AVI: Opening file "E:\GRABACION\cbreakwithmpeg\HERRAMIETNAS\total\prueba.avi"
AVI: OpenDML hierarchical index detected on stream 0.
AVI: OpenDML hierarchical index detected on stream 1.

I see that virtual dub doesn't generate the file pruebacortea.avi and the 3 steps of virtualdub take about 10 seconds.

Could you help me?
Many thanks and sorry for my english!

Sorry, I can not help as I do not use virtualdub.
Maybe someone else, or you could ask you question on the forum of www.videohelp.com

Thanks.

How do you do after compskip detects the commericials to can remove from avi?

Many thanks!

Once Comskip has detected the commercials and generated a .edl output file (listing once commercial per line) mencoder can be used to remove the commercials.

mencoder can take an input file, and output and an .edl file.
Please have a look at the mencoder help (google for mencoder man page) how to do this or study the batch file listed above.

I would like to add a little something to help out my peers.

comskip's generated VCF files disable video processing.

To fix that problem, I put a "scripts" directory in my capture directory.
Then I put the following batch file.

Code:

@FOR %%A in (*.vcf) DO scripts\generate_script %%~nA "scripts\de-interlace_recompress.vcf" "%%A" ".\temp\%%A"
@FOR %%F in (.\temp\*.vcf) DO vdub.exe /s"%%F" 

@rem @del *.vcf
@rem @del temp\*.vcf
@PAUSE

My de-interlave_recompress.vcf is as follows

Code:

VirtualDub.audio.SetSource(1);
VirtualDub.audio.SetMode(1);
VirtualDub.audio.SetInterleave(1,500,1,0,0);
VirtualDub.audio.SetClipMode(1,1);
VirtualDub.audio.SetConversion(0,0,0,0,0);
VirtualDub.audio.SetVolume();
VirtualDub.audio.SetCompressionWithHint(85,48000,2,0,16000,1,12,"AQACAAAAgAEBAAAA","MPEG Layer-3 Codec");
VirtualDub.audio.EnableFilterGraph(0);

VirtualDub.video.SetOutputFormat(7);
VirtualDub.video.SetMode(3);
VirtualDub.video.SetFrameRate(0,1);
VirtualDub.video.SetIVTC(0,0,-1,0);
VirtualDub.video.SetCompression(0x34363278,0,10000,0);

                }
                header.Close();
                // open the cuts vcf file made by comskip
                StreamReader body = new StreamReader(input_vcf); 
                body.ReadLine(); // remove 1st line.
                // this copies the cuts file into the output
                while (body.EndOfStream == false)

                body.Close();
                w.WriteLine(last_line);
                // closing all files is important if you want a complete file at the end of execution
                w.Close();

                System.Console.WriteLine("Error : " + e.Message.ToString()); 
            }
        }

}

It's actually quite simple, but can help out people so they don't have to edit by hand their 100s of vcf files.

Cheers!

Nice explanation, well done.
In case you need to re-encode then the output resolution for the video to be usable by Comskip only needs to be 320x200 when processing SD, HD may need 640x400
