audio sync

[commiewop]

i'm hesitent to post this but...

i'm having audio sync issues

ok i followed the guide here for encoding a movie to svcd using dvd2avi and avisynth, the audio file i got said -66ms delay, the only prob i can see is that in the beginning of the movie it doesn't have a set video type, jumps from NTSC, to film xx%, back to ntsc...but eventually it gets back to film 95%. i checked the d2v file and it said this

7 0 0 2 3 1 2 3 1 2 3 0 1 2 2
7 0 60 2 3 1 3 1 3 1 3 1 3 1 3
7 0 C2 1 3 1 3 1 3 1 3 1 3 1 2
7 0 12D 2 2 3 1 3 1 3 1 3 1 3 1
7 0 192 3 1 3 1 2 3 0 1 2 3 0 1
7 0 1F3 2 3 0 1 2 3 0 0 1 3 0 1
7 0 256 2 3 0 1 2 3 0 1 2 3 0 1
7 0 2D8 2 3 0 1 2 3 0 1 2 3 0 1
7 0 355 2 3 0 1 2 3 0 0 1 3 1 3
7 0 3B7 1 3 1 2 3 0 1 2 3 0 1 2
7 0 418 3 0 1 2 3 0 0 1 3 0 1 2
7 0 478 3 0 1 2 3 0 1 2 3 0 1 2

it continues on like that, then it changes somewhere again to

7 0 EC9 3 0 1 2 3 0 1 2 2 2 2 2
7 0 F72 2 2 2 2 2 2 2 2 2 2
7 0 FDC 2 2 2 2 2 2 2 2 2 2 2 2 2 2
7 0 FEE 2 2 2 2 2 2 2 2 2 2 2 2
7 0 10A7 2 2 2 2 2 2 2 2 2 2 2 2
7 0 116C 2 3 0 1 2 3 0 1 2 2 3 0

and does odd things like...

so i guess what should my dvd2avi settings be? for the most part is says FILM 95+% but thre are random times it doesn't...forced film, should i use ivtc, or even select none i think i chose FF...if this was the wrong line of thinking or if there's an answer please let me know...but thats my guess at the problem...cause after i encode audio with the 66ms delay and run the vid and audio thru bbmpeg it ended up out of sync

thanks

Welcome,

No need to hesitate: This is one of the best 'newbies post' I've seen in a while, you tell us clearly what the problem is, you provide a lot of information.
*sigh* why can't every post be like this...

To your problem: I'd save the .d2v with FF enabled, and try to find places where DVD2AVI say's NTSC. Then open the simple AviSynth script below in VirtualDub(Mod):MPEG2SOURCE("dvd.d2v")Again, find the place that DVD2AVI called NTSC. Look at it. Does it look OK? If it does then use the ForceFilm'ed .d2v. If it doesn't, then go back, re-save the .d2v with ForceFilm disabled and IVTC manually in AviSynth. Decomb is a big favourite here.
Good luck.

Just a quick addition .... If you're not 100% sure of the source, you might consider creating a test.d2v file with Force FILM turned off, and using ParseD2V, as described in http://www.doom9.org/ivtc-tut.htm. It will supply frame numbers that you can then inspect, to see what these pulldown transitions look like.

Oh, and the sync issue might by caused by using "66" instead of "-66". That will make a 132ms difference. :cool:
