I am completely new to the DiVX format and have a film that has a sync problem. The sync gets worse as the film progresses, I have read its possible to fix lip sync problems, and have dabbled with VirtualDub but can anybody tell me an easy way to fix the problem? I have not yet found a simple explanation of the tools needed and simple instructions on how to fix this problem. The film is an AVI format movie with compressed sound, in MP3 format. I hope someone can point me in the right direction...
well you've probably done this allready, but just to make sure... 1) read the guides... read over them again... so on :-P i've gone thorugh the whole thing myself having no help except the doom9 guides... and honestly although doom says he hasn't encoutered one unsyncable movie i've still got one on my HD that i'm just not able to sync! (: anyway it's hard and in your case there is no easy way to this... the way that is described in the guides is the only one i've heard of that solves that problem at all. and honestly you need quite a bit of luck too... pretty much a trial and error thing... don't get desperate... this whole stuf just comsumes an awful lot of time... so i've you've still got your DVD to do the backup, try to start all over again... it's not unlikely that it'll be faster then. otherwise just leave it for a while... do some other stuff... and don't throw away any valuable data... you'll regret it later on when you've found the right solution to your problem! (i AM speaking from my own experiences! :devil: ) ok... so just one last hint: check the length of your audio and video files to see if they are the same... if not i'd say you rather restart the whole process... it's faster! regards steVe
Yes, I read the guide, but there are still things I just don't know about, for instance, it is a AVI file with the audio in MP3 format, so how do I seperate the file into video and the compressed audio? Also, the guide is not exactly easy to follow, as it assumes that the reader knows and understands the software involved. I have loaded the file into VirtualDub before, and then it mentions CBR and VBR and so many seconds of skew... I tried changing the interleave, but that causes white noise instead of the audio...
i know what you're talking about... but try to make yourself familiar with virtualdub... it's definitely worth knowing how to work with it... to seperate audio and video (actually you just save the audio seperately) follow these steps: -load video - go file/ save wav ...[yes i know it's not smart to save it in wave format but it's the only easy way i know] this will give you a seperate wave file... but one more questions: what program did you encode with? steVe
a downloaded movie! well that changes everything a bit! i've had some problems there too... sometimes it helps to just load the movie in virtualdub and save it with direct stream copy switched on in both audio and video menu! this created a new file header that sometimes corrects bad information that got corrupted when you downloaded the movie! if that doesn't help, you've got to play with the manual syncing... and that takes an awful lot of time! regards steVe PS: i know it's sometimes really bad when downloading movies that haven't been done properly... but on the other hand what do you want to do?? sue them? :-P
Well here's one problem, Virtual dub will mess up with VBR MP3 files. Im assuming your using GKnot for your encodes right? Gknot creates VBR Mp3's with the use of Besweet. If that is the case then you have to load your movie in Nandub, which is a variant of VirtualDub that has support for VBR Mp3's and AC3 files. If you want to extract your movie just go the File > Export Wav and save the file. This won't actualy be a wave file but the Mp3 file with .wav at the end. Just change the extension to .mp3 Another problem with your audio is that you don't need to change the interleaving options, you only have to worry about the Skew options. But hopefully processing the mp3 in Nandub should fix your problems with the sync issue. Try small intervalls at once like 50ms. This won't affect much at the beggining, but later on those 50ms add up and will affect the end of the movie. Note: 1000ms=1sec
