Please, SVCD Nightmare's, I'm Desperate, HELP

About 2 weeks ago, i bought a phillips dvd player, and yes, i made SURE it would read both VCD/SVCD. Anyways, that's not the problem, the problem is no matter what i try, when i encode an svcd the audio will ALWAYS gradually go out of sync. I have tried extracting it with Virtual Dub, i tried DVD2SVCD (AVI2SVCD)and I mean NOTHING seems to help. I have searched this forum over soooo many times, looking for the answer, but I can never find it. In Tmpgenc, I have used both the NTSC and NTSC film templates, i have tried many many different bitrates. i have tried adding all the extra features, i have tried adding no extra features, but whatever happens, the audio ALWAYS slowly falls out of sync and just get's worse as it goes along. I have checked the avi with virtual dub, div fix, you name it. Nothing helps. My system specs are as follows (if that helps):
AMD Athalon 1800+
256 Mb of RAM
GeForce Graphics Card

If anyone can help me, You will from then on be my personal hero. Thanks

Changeing between the NTSC and NTSC Film templates will no Good Cuz what template you use is Up to the Frame rate of the File not anything else..And does the audio gradually go out of sync in the Files before you burn them to Disk or only when watching on your DVD Player..If it is in the Files before burning to disk then it is Because the audio and video files are of a Different length, so to fix that you would have to Stretch/Shrink the audio to the length of the Video and mux it back together...

First off, thanks for your reply. And it slowly goes out of sync about 3 to 4 minutes into it. I have tried everything i could possibly think of, but the problem still remains.

Well if it gradually goes out of sync then that is usually from the audio length being shorter than the Video length, this Can happen Because sometimes avi files aren"t exactly the Frame rate they sey they are ,Meaning an avi file with Play at say 23.95FPS but it will say that it is 23.97fps so you you encode it to exactly 23.97fps it goes out of sync, And the other reason for this type of de-sync is that the audio length has changed from being decompressed or encoded to a Different Sample Rate, this can change the length cuz some audio samples can get lost which can gradually cause de-sync..The Trick to fixing this is to de-Mux the out of sync Mpeg file, and extract the audio from the source AVI file, then compare the length of the Mpeg audio and the audio extracted from the Source file, the audio should be shorter or longer than the video file, then take the audio file and Put it in a Good Audio editor Like Cool Edit or Sound Forge(I use Vegas Video) to stretch or shrink the audio to the exact length of the Video, then you can either export the audio as a Mp2 audio file or as a WAV file that you can encode to Mp2 and Mux with the Mpeg Video..I do this Quite often with Files that are Captured Cuz they can go out of sync quite often and this Method works Perfectly about 95% of the time..

Hi,

What was Your source SVCD? Captured with some card and some crappy audiocard/AC97 ?
Audio can be 'streched' with extra tools to match video-lenght.

To avoid audio problems You first must have right, non dropping, settings for capturing.

Your Computer is Plenty fast enough, and even if it wasn"t it wouldn"t cause De-sync...

I had the same problem and gave up in the end. I suggest treating yourself to a DVD+writer they have come down in price. When i copy home movies from my digital camcorder they quality is brilliant and no sound problems. Also if you copy downloaded movies or dvd the qualitys is near perfect. Well worth it PS i use Unlead moviemaker 2

Best of Luck

First off, the source was a divx avi downloaded from kazaa. Roughly around 700 or so MB. And yea, i've tried stretching the audio, but it never seems to fail to still lose sync as time passes. One quick question, what would be the best mpeg-2 (svcd) playback player (ie.real one, gDivx, the playa, etc..)

And yea, that's what i thought too, Luisifer, but wanted to make sure, that it was COMPLETELY hopeless LOL thanks for the reassurement.

And pete... oh lord I will be flying high the day i finally break down and get one. I realize they're expensive, but if i really pushed the bitrate (lose alittle quality, but eh) i could fit 2 or 3 on a DVD disc, which i probably wouldn't do, cuz i'm a huge quality freak. But that's the way I hope to steer into the direction of in the next couple of weeks/months. Any suggestions anybody on a particular decent priced, good quality DVD writer would be?

try diff software

March 25 2003, 3:34 PM 

what software are you makeing the svcd with ?had same prob but got over it with nero and the mpeg2 plugin .try it and this is a good dvdrew in short copy dvds in 15 mins .
DVD Recordable Drive
Pioneer's DVR-A05 drive doubles writing performance across the board with 4X DVD-R, 2X DVD-RW, 16X CD-R and 8X CD-RW capabilities. The new 4X DVD-R recording speed translates into approximately 15 minutes to fully record a high-speed 4.7 GB DVD-R disc. Using data writing software bundled with the drive, the DVR-A05 also offers two-minute quick formatting for DVD-RW data discs, and allows finished DVD-RW discs to be "unfinalized" for writing additional data files. A DVD authoring tool and DVD/CD data recording application are also included with the drive, as well as blank 4X DVD-R and 2X DVD-RW discs.you can get this for under £170.00 dont get a ****y one from cp world or some other place like that what a ripp off

TRY THIS!

March 13 2003, 8:24 AM 

Open Womble Mpeg2vcr, go to 'tools', click on 'Mpeg GOP fixer' than input your mpeg file, check off 'all the above', name your output, and hit scan. It should find and fix all audio sync problems..

Had the same problem

April 4 2003, 8:05 PM 

I had the same problem and was ready to give up. I was using vob to strip and convert audio and then used Tempgnc to encode . Then I used Nero to burn it . I came up with audio sync problems everytime. I made a simple change and it worked wonders , I switched from Nero to NTI cd maker 6 platinum. I have burned about 7 movies since then and not one of them had any problems. Nero is your problem. Dont try anything different from your encoding just download Nti from kazaa and then burn your movie with the svcd template , I think you will be surprised how easily things work after you try this. I hope this helps you out . Let me know.
