TalkingSoft.com Forums: out of sync again :( - TalkingSoft.com Forums

Hi guys i hope some one can help me with this problem ,

I have a avi file which plays fine all the way through , but when i convert it to dvd (vobs) it all goes out of sync , ive used gspot and it says i have the right codecs installed ... any ideas what is happening guys ?


many thanx for ya time

Not a simple answer. Didn't give me enough info to answer... somehow during process of converting/encoding to DVD (MPEG2 format) a lag of video/audio occurred.

Assuming you are using a quick, dirty method with an all-in-one program for converting?
Some original AVI have AC3 or variable bitrate MPG layer 2 audio.. so don't always translate very well. Also, possible the original AVI was not encoded very well and may be out of sync... but likely won't notice till half way through the movie.

Did you try opening it with VirtualDub? Maybe this AVI has a VBR audio stream so you have to save the audio part separately to WAV format and later, when converting to DVD, use this audio file as the audio source.
You can download Virtualdub and its mods from http://www.free-codecs.com/

Yes Mischcabob it is only really noticable half way thru the film , im useing dvdsanta to convert the avi , i have total divx codec pack installed and also VP6 VFW codec ,divx codec and xvid codec , is there a better way but still quite easy other than a "dirty method" ?


chp i cant see that dvdsanta allows to add the audio from a different source


could it be something to do with coverting in PAL format and not NTSC ?


many thanx so far thou guys

So did eliminate possibility that orig AVI file has a video/audio lag?

If you in north america/japan... should be using NTSC (29.97fps). Unless your DVD player can play both PAL/NTSC?

Chp mentioned VirtuaDUB Mod.. that's preferred method I use. It can get technical quite fast... Basically involves demuxing audio portion... converting to 48kHz WAV file and saving video as separate elementary stream. I use TMPGenc Plus to multiplex both audio/video streams to encode to MPEG2 (DVD format). Also, I use external audio encoder called LAME plugin with TMPGEnc to get superior sound. Have I lost you yet?

Here's the guide that might help (some steps may not apply):


Other guides you can try:

you lost me after the 2nd line lol , as i say im new to doing this and to be honest its bloody hard lol , i have done some with dvdsanta and it was easy just load the avi and bang you got the dvd click yes to write and its all done , i like it like that hehehehe

Im in the UK thats why i used PAL, ill have a look thru the links and see if any can make sense lol


thanx again

Sorry about that.. been doing this for years. DVD Santa is a great program that works most of the time, but sometimes "it throws you a curve ball."

It's only when you get VBR Mp2 or AC3 that it might have problems. Use GSPOT to identify what type of audio and video codec it uses. Just matter of converting MPEg audio to WAV... any converter will work. Can still use DVDSanta which should allow you to select the video (AVI file) and the newly converted WAV file. Can also try Nero which has easy learning curve.

Anyway, check out the links and if you have any further questions, don't hesitate to ask.
PS. Check out the pinned topic for more help

Thanx a lot for your help ill have a look and see what i can do

ill report back soon

Im back lol, no matter what i do when im in TMPGEnc i follow all the steps but on section 4/5 of the wizard im getting 167% of the disc size and can get it down to 97% . ive gone thru it about 20 times selecting NTSC and PAL (the disc does say NTSC but is it still alright to write in pal as im in the UK)

any ideas hoe to get this size down ?

thanx

Have to convert the MP2 audio that you got from VirtualDub into WAV that's why. TMPGenc can't interpret VBR audio files or AC3 for that matter.

Any typical audio encoder will work. I use CDEX (freeware), but can use Nero to encode into WAV as well.

i tried ripping the audio useing virtualdubmod but it says 16 hours lol , when the help files says a few mins lol

shall i give up heheheh

I said at the beginning that VBR is the problem

But 16 hours??? That's a quality!

Well, so what VirtualDub or GSpot reports about the audio format exactly? Would you please share that information with us?

for the audio gspot says "0x0055(MP3) ID'd as MPEG-1 Layer 3"

as it stands up to know ..... i tried to rip the audio from the avi , and it was 284mb , then i tried to convert to wav which made the file 43.4mb ive know tried to put them together again in tmpgenc and its doing but says 36 hours lol , a quick query when the audio is in .wav format can you play it and hear the audio or just hear a high pitched squeal ?


ill keep trying coz i dont like to be beat but i must say this is bloody doing my head in hehehe

thanx

Sorry having these probs. Gspot indicates MPEG1 layer 3? Sounds right. Also, may have noticed VBR is highlighted, not CBR.

284MB sounds right for compressed direct stream copy. It only takes me about 20-25 mins demux typical stream from VirtualDub Mod. DON't convert to WAV using VirtualDUB... doesn't work since only changes the header.

43.4mB can't be right.. should be over a 1 gig if you expanded to a WAV file. To encode WAV file I just run Nero 6 StartSmart. Under CD..audio..encode audio files
Add the MP3 file and select 48khz WAV as destination format.

I assume you have fairly fast computer... anything less then P3 computer will be too slow. Be aware that encoding the file in TMPGEnc does take several hours... normally for me using Athlon XP 1600+ CPU... takes about 5-6 hours. Make sure you select 1-pass and MP2 CBR (constant bitrate)in TMPGenc. That will shorten your time by least a half!

HI again .. ok ill try to convert in nero and see what results i get from there lol ,

i have a P4 3.2 HT with 768mb 400ddr mem so shud beable to cope with it lol if not i will give up lol

thanx again be back soon
