NoAd is a program for commercial detection in vdr recordings. It uses several characteristics of the film, like station logos and AC3 sound, for the detection and produces cutting marks for the recording.

Hardware requirements

Software requirements

  • libmpeg2
  • ImageMagick (optional)


First install libmpeg2

tar xvzf mpeg2dec-<VERSION>.tar.gz
cd mpeg2dec-<VERSION>
./configure --prefix=/usr/local
make install

Now you can install NoAd an usual

tar jxvf noad-<VERSION>.tar.bz2
cd noad-<VERSION>
./configure --with-mpeginclude=/usr/local/include/mpeg2dec
make install

NoAd needs write access to the video directory!


It's best to start NoAd through the reccmds.conf. So Add the following lines

Run noad                         : /usr/local/bin/ -start
Run noad, all recordings (batch) : /usr/local/bin/ -batch
View Cut list                    : /usr/local/bin/ -view
In prozess                       : /usr/local/bin/ -count
Stop noad (killpid)              : /usr/local/bin/ -killpid
Stop noad (killall)?             : /usr/local/bin/ -killall
Remove all marks                 : /usr/local/bin/ -marks.vdr
Remove all pids                  : /usr/local/bin/


Parameter (short) Parameter (long) Description
-s --statisticfile name of the file for statistic-data
-v --verbose increments the log-level, can be given multiple
-b --background start noad as backround-process
-p --priority priority when running as background-process [20...-20] default is 20
-c --comments adds comments to the marks in marks.vdr
-o --overlap try to detect repeating sequences before and after the break
-a --ac3 experimentel: use ac3-sound for ad-detection
-j --jumplogo looks for vertikac drifted logos
-O --OSD sends an OSD-Message to the running VDR-instance(localhost:2001) for Start and End
-S --savelogo saves the detected logo for later usage
-B --backupmarks saves an exsiting marks.vdr to marks0.vdr
-n --nelonen special behavior for finnish stations
-V --version shows the Version and exits


After using NoAd to mark all commercials in a recording one shouldn't use the cutting function of VDR blindly. NoAd is not perfect and the telestation do some nasty things with there logos. So it's always better to look manually over the cutting marks before really cutting.
