Sound out of Sync with SVCD's

[David Jones]

I am a very 'newbie' to DVD ripping and backing up my own DVD's to SVCD's. I use the Gordeon Knot package, very good, easy to use once you get the hang of it. This produced a DivX5 AVI movie. Excellant quality etc. etc. I then started using TMPGEnc-Plus to encode to SVCD. No sound peaks were showing on the sound indicator below the screen. Back to the drawing board; used Nandub to extract the sounf file from the DIVX file saved it. Started TMPGE again loaded in the movie file, loaded in my seperate sound file. Encoded 10 minutes as a test, played it, Picture fine, sound fine but out of sync. Where am I going wrong?? Please make the answer simple, if possible.

Dave.

Welcome to the forum! I hope you find it helpful.

My best recommendation is to first try a recognized and understood methodology, such as the ones Doom9 has created in his format conversions (http://www.doom9.org/conversionguides.htm) guide pages. There's a TMPGEnc AVI - > SVCD methodology there, as well as one using DVD2SVCD (in it's AVI2SVCD mode).

Thanks I will study those tips. I tried converting an AVI file with TMPGE and found the sound peaks were showing when I scrubbed through the movie. I made a short SVCD and the sound sync was fine. I then tried using nandub to rip the sound off as a .wav file, loaded it into TMPGE and the sync was perfect. I notice with the trial version of TMPGE -Plus that you can adjust the sound sync by so many milliseconds; how do you tell which way to go + - and by how much?? Trial and error on a short section?

When you adjust the sound, think of it this way. You are sliding the entire sound track either ahead in time or back. So if you use negative numbers, the sound will come earlier and vice versa.

Thanks Mac, answer is so simple, I am sorry I asked the question now,
Cheers anyway.

Hi Mac,

Did what you suggested, finaly got the sound in sync after about ten attempts on a small 2 min section of the movie. I ended up setting -200 millisec. on the Audio. I thought great, sorted. Went 3/4 way through the movie endoded 2 mins. to check the sync and it was about 4 seconds out. It would appear that it runs at a differant speed to the movie?? This makes it get worse by the second as you watch. Any more ideas? or would I be best to start again? The movie by the way is House on Haunted Hill.

There is a way to do this by sampling a sound (door slam, gunshot, etc) at the end of the movie, stripping the audio, and stretching or condensing the audio by whatever the offset between audio and video is. Its not too tough but takes a little time. If you want exact procedures, let me know and I will send them to you. Otherwise the easier way, if you still have access to the movie, is to simply rip it over again.

Hi Mac,

Would appreciate it if you could point me in the right direction for the software to convert the audio so that it is correct for the Video. I Ripped the audio off again, this time using Nandub. It gave the message Improper VBR Audio encoding etc. etc. Using this .wav file was better, but still went way out at the end of the movie. I have done about 10 dvd's now using Gideons Knot set of programmes all of them do not show a sound track in TMPGE-Plus so I think if you could send me the info I will have to blow my mind working it out to chabge all the Audio Tracks. This will teach me not to rip into a DivX5 file, and choose SVCD in the future. Thanks, hope I am not bogging you down too much.

If you are trying to go straight from dvd to svcd, why not try DVD2SVCD using tmpgenc to produce this. You can find it in the download section. I will send you via pm the instructions for fixing your existing svcds. Give it a try.

Thanks for that again Mac, I will download DVD2SVCD and give it a whirl; wait for the next gripping installment. Cheers.... Dave.

I made a recommendation to follow the guides 2 days ago. :-)

[David Jones]

Thanks to you all for the guidance, DVD2SVCD works a treat. Nice one JGGIME and Mac for the sound advice..........Dave.
