Open GOP problem

[varunb]

I hope I hav posted this in the right place.

Well the problem is that i recently ripped a ntsc dvd of mine. I decide to create d2v's of each vob's. Before creating the d2v files, dgindex reported that except the 1st vob (in order according to the movie, i mean), all the other vob's had open GOP's but i neglected this alert as i had selected the 'force open gop in d2v' option. So when i added all the d2v in a single avs file & watched it in mpc, i found that the video jerked a bit after the end of a d2v & before the beginning of the next d2v. This problem didn't occur when i created a single d2v of all the vob's. I know that this is bcos of the open gop but is there a way to fix this problem so that I can watch the avs that i had created without video jerking at those portions ? I want to follow this method bcos the ac3 streams i had demuxed had different delay values.

I hope u guys understand what i am trying to say here !

The two have nothing to do with each other. You do not need to set that option, nor will it help you in this scenario.

So when i added all the d2v in a single avs file & watched it in mpc, i found that the video jerked a bit after the end of a d2v & before the beginning of the next d2v. Post the script. Are you viewing the AVS script or a file encoded from it? If the former, you may get a small jerk as each new VOB file needs to be opened. I wouldn't expect there to be a problem in the encoded file.

I know that this is bcos of the open gop but is there a way to fix this problem so that I can watch the avs that i had created without video jerking at those portions ? Nope, the open GOPs have nothing to do with it. Use a single D2V.

I want to follow this method bcos the ac3 streams i had demuxed had different delay values. But that's just an artifact of processing them separately. You shouldn't get any sync problems using a single D2V.

Well neuron2, there was a small jerk in both the encoded avi file & in the avs that i was viewing, which, as i had said bfore, was not there when i created a single d2v file.

But that's just an artifact of processing them separately. You shouldn't get any sync problems using a single D2V.

There were sync problems on using a single AC3 stream. Well when i checked all the individual ac3 streams in vdubmod, i found that the few bytes of those ac3 streams were corrupted. Maybe, that's why i was getting the single ac3 stream asynchronised. So what shud i do now ?

If so, your cuts probably lost some frames. Remember, the timeline is not frame accurate and has limited granularity. You probably won't be able to make seamless segments like that. That's why I recommended to use a single D2V project. If you did not make any cuts and made a full project out of each VOB, then I don't see any explanation, and since you did not post your script as requested, I can't say anymore about it.

So what shud i do now? Fix the AC3 and make any required sync adjustment manually. Don't follow up on that here; it's not a DGIndex issue.

Well i didn't make any cuts. I made a single d2v of each & every vob file without creating any starting or ending points. Moreover, i never used the corrupted ac3 streams. Infact i used ac3 streams fixed by beslice. Ok i believe u that its not a dgindex issue but then wat is causing those jerks when i view the encoded avi, esp at those points where one vob supposedly ends ?

[neuron2]

I asked twice for your script. This is now the third time.

Well if u r asking for the d2v scripts that i am trying to join, then i hav attched them below:

Obviously, I mean your Avisynth script. A D2V file is not a script.
