Everything worked, except sound is out of synch

[Rooster6975]

Hello,

Ran through DVD2SVCD and it worked. I can watch the movie on my set top DVD player much to my amazement. The bin file 825 MBs but it still burned successfully to a 700 MBs CD (will wonders never cease) without overburning. However the sound is off. It is fine up until it hits a glitch in the video which was present in the original AVI. In the divx, there is a moment when the video becomes ghosted and it obviously drops a small portion of a scene. However, it quickly recovers and moves on and the audio never gets out of synch. On the SVCD I just burned, as soon as it hits that point, the audio is out of synch for the remainder of the video.

How do I fix this? I know perfectly well how to fix out-of-synch audio on a divx, but I have no idea at all how to do this with an SVCD. I can go back and cut out the bad scene in the original AVI and then re-encode, but is there another way to edit the finished BIN/CUE files without having to do this?

Thanks,
R.

well, you could extract the MPG from the BIN/CUE using VCDGEAR

then fix the synch in the MPG and re-author with, say VCDEASY or NERO
only way i see to fix the synch is demux the audio with TMPG MPG TOOLS, fix it with cool edit pro or something, and then remux to the mpg using TMPG MPG TOOLS again

I apologize if I misunderstood your question

RE 825 image file fitting on a 700 CD - in SVCD mode a 700 CD actually holds 800 megs, and an image weighing 825 megs could actually store 800 megs of data, and the 25 remaining megs could be subchannel data that you don't see, or bad comression, or somthing, I think :cool:

Hi!

I think it would be easier to fix the divx, if you still have it. The CD was wasted, so you have to burn a new one. May be correct the avi and then create a new SVCD. I dont think U should do something like cutting the audio and shift the second part etc. If it plays well in the avi it should be able to be converted to mpeg.

Which encoder do you use? CCE 2.67 loose frames due to beeing a beta ver. The problem was corrected in 2.67.00.22 relase.

Check your codec also with Gspot. Maybe that couse this problem.

For the last: try to encode the divx to another format with virtualdub. If I were you i would use xvid and cbr mp3. Check the sync in the new avi. (This is for only testing, becouse you loose quality. Anyway, if quality loss is not significant and the xvid avi is good, make svcd from that.)

Tip:
Use daemon-tools to check the created image file. This way you can avoid of things like this.

It's fixed! I tried out the Cool Edit Pro method (just for fun), but it was getting more and more difficult to synch the audio. So I went back to the original AVI and cut out the bad part from the nearest keyframe to the next keyframe. Re-encoded with TMPGEnc and 6 hours later, it works flawlessly. Plus I got a coffee coaster out of the deal as well!!

And just to show you how much of an SVCD newbie I am, I used Daemon Tools to check the original finished product. It worked fine, up until it got out of synch. I read a bunch of Guides which indicated that just because my computer playback with WinDVD was out of synch, doesn't mean it will be on my set top DVD player. So I gave it a go, and it was absolutely identical to my WinDVD experience. At exactly the same point, the audio was out of synch. So now I know! But I really did need that coaster, my wife got mad at me for the last coffee ring I left on the desk.....

Thanks,
R.

Regarding coffee coasters... do you watch Monk ?

STOTTLEMEYER: What are you doing, I have a coaster

MONK: I always put another one underneath, it’s – a – it’s like backup

:D
