easiest way to change a m2v gop structure?

[cudencuden]

im using vobedit to demux a dvd..but watever m2v file i get i get an gop structure error when i import it to tda..did not happen to the last dvds i do it on..so i dont know...i fixed it by using tmpgenc and demux it again to m1v file but the quality was not as good as the original m2v file..any help?

[guns1inger]

don't know if restream can fix this, but it mighyt be worth a try

This might do the job: MPEG Sequence Maker.

Valid GOP lenghts (max.) are 15 for PAL and 18 for NTSC.

can u have m2v files as input for MPEG Sequence Maker ? but i tried restream...how would u fix it in restream..im messing with restream rite now..seem like the new output retains all quality which is good news some wat

[jimmalenko]

I'm pretty sure that MPEG-VCR has a GOP fixer.


Forum search on "fix GOP" reveals:

I don't know - I've never used it. I was just going by it's description, and the fact that it's been recommended for similar requirements in the past.

Try it out... You might also try changing the "m2v" to "mpg".

cant input m2v with MPEG Sequence Maker, and i want to retain the quality, have to have the m2v format as product so i can do some audio editing, thats y i don think mpeg-vcr would help either..and i tried mpeg-vcr and it ddint find any error..so im really want to fix it using restream cause it gives my wat i want..heres restream settings

[jimmalenko]

Your M2V file is just video anyway, so I don't see how audio editing comes into it ???

You could always just remux the M2V and your audio to a MPEG file, run that through MPEG-VCR, then do your audio editing.

[cudencuden]

i dont want mpeg format..i need m2v because i when i make the dvd in tda i use my pre-made audio as audio and make the dvd then i convert to avi using fairuse...wat im trying to do is make a avi dvd rip with my own audio in it with good quality

[jimmalenko]

You can tell TDA to use the MPEG for video, and then a totally different audio file for audio

... or you could demux the MPEG after the GOP has been fixed to get your M2V back.

[cudencuden]

i know.but i would save that for last resort cause then the quality wont be as good

That's BS !

You're not touching the quality at all - just joining and splitting streams.

[cudencuden]

i aldready did wat u said using tmpgenc ..may be i didnt do it rite or something but there was significant quality change

[jimmalenko]

Then yep, you didn't do it right.

The only time you change the quality is if you re-encode the video.

[cudencuden]

let me try again with tmpgenc

[cudencuden]

been trying for the longest time..the quality does change..can u show me how to do it?

[jimmalenko]

Are you using the exact same software for playback ?

And by "quality change" are you talking about a difference between your M2V file prior to muxing and the MPEG file after muxing ?



BTW, you could always author with IFOEdit - I don't believe it is so anal about DVD compliance, and it's not as if DVD compliance matters here, since you're just gonna convert to AVI anyway.

[cudencuden]

hmm good suggestion..let me give that a whirl
