Two sided DVD. Cutting out intermission garbage.

Two sided DVD. Cutting out intermission garbage. 

Hello, and welcome to Doom9's forum! If you've set DVD Decrypter to IFO mode, you can deselect a particular chapter from a rip. Chances are the logo you want removed is in a separate chapter. Be aware that after joining the vob sets in a single .d2v, you may end up with "extra" black frames at the join point. If so, they should be removed prior to encoding, typically with the use of the AviSynth Trim() filter. If you leave them in place, you will end up with audio desync in the 2nd half.

The logo, and black frames are in the last .vob of the first side...unfortunatly. Maybe I can rerip removing that chapter. Also, didn't know about that Trim filter. Thanks! edit. Hmm. The audio will be quite a challenge here. How will I know if cutting that segment (the logo and the black frames) won't screw up the alignment of the audio track to the video on the second side. Wouldn't there just be blank sound to go along with the black frames? ugh. Will the .ac3 correctly remove that chapter in the audio if I use the DVD Decrypter meathod?

It's been my small experience that the .ac3 demuxed by dvd2avi does not account for those frames, so removing the frames means that the entire soundtrack stays in sync. I do not know the reason for their appearance, as I'm no dvd2avi expert. But my guess is that they are "created" to complete an MPEG GOP sequence. Of course, when I was doing this, I was working with DVD2AVI 1.76, the current 1.77.3dg version may not produce these frames. Look for them at the join point. If you see 'em, just edit them out.

By "just edit them out" I presume you mean with the previously mentioned Trim() filter, correct? I'm not missing some neat feature in DVD2AVI? Thanks for the welcome, and the help.

With my method, you end up with a single .ac3 soundtrack and the possibility of removing a few frames. That assumes that the current DVD2AVI version still has this issue, which I haven't confirmed and can't for a day or two, as I'm traveling. With Hakko's method, you have two separate .d2v files, as well as two separate demuxed .ac3 soundtracks, and the two video streams are merged in AviSynth. If you want to merge the soundtracks in AviSynth, as Hakko warns, you must first transcode to .wav. I'm not familiar with your guide, so I don't know if this is an issue for you or not.

Just an update on what I'm doing. I've used a version of hakko504's meathod. I've created two different .d2v files with DVD2AVI with the black frames and logo already cut out. Then I created my script with the two different .d2vs and did everything else normally. I deleted the two .ac3's generated, and again used DVD2AVI to create a .d2v and .ac3 without anything cut out whatsoever. I then deleted the .d2v and saved the .ac3 and generated my ogg file using that file in Oggmachine. I'm now using VirtuaDubMod (using the two .d2vs with the extra frames already cut out...double checked in Gknot and VirtuaDubMod) and generating my final video. Then hopefully when I use OggMux to combine the audio and video, everything will work. From what both of you have said, I think it should.

Well, it didn't work. Everything is synched up fine, but the logo music is still in the audio, along with a few seconds of no sound on eigther side. Of course, the logo was taken out of the video, so the audio is over 10 seconds late on the second half. Damn.

Back from the past 

I have the same problem with "Dances With Wolves". I want to make a 3CD XviD (Auto GK). The movie is originally split in two discs. And NO, the intermission message is NOT a separate chapter. Altough the last chapter on disc 1 consists of two cell ID's, but leaving the last cell out does not cut away the message. What I COULD do is to encode the first disc into 2CD XviD, and the last disc as a 1CD XviD. I could use Vdub to cut the intermission msg away at the end of CD2. A workaround maybe, but not a solution. Is there a tool (like VDub for .avi) for cutting vobs, with frame accuracy? :confused:
