remove commercials

[Singh00]

Hi, I recorded a video off my tv card into mpeg2. I want to use gknot to compress the file, while at the same time remove the commercials. Here's what I do to do a strait compression:
1. load mpeg in DGIndex, select my in and out points, demux all, save
2. convert the audio to mp3 with besweet
3. open the dv2 file and mp3 in gknot, select compression and stuff, IVTC (its a movie), and go

I have two questions:
1) Do I really need to use DGIndex? What does it do in my case?
2) How can I edit out the commercials? I was thinking of making a very simple AVISynth script, does anyone know the parameters to use? And if I go with the avisynth script (and thus eliminating DGIndex), how can I compress and edit my audio to match up with the video?

Thanks

Why DGIndex? Because in combination with the AviSynth plug-in DGDecode.dll -- which is the MPEG2Source() filter -- MPEG-2 video can be manipulated within AviSynth. Otherwise you wouldn't be able to use AviSynth.

Assuming your audio is captured in Linear PCM (.wav), you can use the WavSource() filter to include audio in your script.

VdubMod has a built-in script editor, which in concert with deleting selected sections, can automatically produce the correct Trim() filter settings to cut out commercials. The procedure is outlined in section 7.2 of the Capture Guide (http://www.doom9.org/capture/start.html), which you must have missed. That guide recommends capturing into lossless video (or nearly lossless) rather than into MPEG-2 in order to achieve maximum possible quality.

Why don't just edit out commercials in ProjectX? (and demux there)

thanks for the replies

for some reason, projectx doesnt start for me. when I double click the jar file, i get the error "could not find the main class. program will exit."

any thoughts?

[edit] nevermind, after compiling it myself it worked.
