Need Some Help Please!

Hi,

I've been asked to create a DVD by my friend and I've been using the following tools:

They are:
Adobe Premiere 6
TMPGEnc
Nero Vision Express

In Adobe, I exported my picture slideshow sync'ed to music (complete with fade transitions) to movie. It created an AVI. PLayed it in windows media player 9. Works fine. Audio and video is in synch.

Then I went into TMPGEnc and tried to create an Mpeg2 file for burning to DVD. TMPGEnc did it fine. However, when I play the resulting MPG file in Windows Media PLayer, the audio skips (or should I say out of sync). So much so that the player skipped a whole bunch of audio to catch up with the video! It's like you get a slow starting song (very quiet), then BOOM, it sounds like it skipped a whole portion and went right into the song! Can't explain it but I hope you understand.

Then at every transition to the next picture, the audio stutters and the video transition effect slows down. The bigger the picture (ie, full screen landscape picture vs portrait) the bigger the problem (ie. increased stuttering and slowness. The pictures look fine when displayed and music is fine when the picture is on the screen. It just happens when it is going from one picture to the next using a simple fade effect.

BTW, the computer is P4 2.6 with 1 gig ram PC3700 dual channel and has a WD raptor 10krpm hard drive. So it can't be the computer being slow??

Anyway, I thought it was just windows media player, so I went ahead and created a test disk to be sure. Played that on my settop player and the same thing occurred.

I then tried varying bitrates and found that in TMPGEnc, using VBR MP2 produced slightly better results, but not by much.

I believe the problem is some setting in TMPGEnc. But I'm not sure what.

Also, in Adobe, what is the fields setting? (No fields, upper field first, bottom field first). Should this match the field order in TMPGEnc?

Can anyone please help?

If you need screenshots, I can provide. Just let me know.

Oh I forgot to mention that the audio clip is stored as an MP3 on the hard drive and I just imported that into Adobe Premiere. It is 44000khz.

Have you tried using constant bit rate in TMPG?

You may want to try saving the video and audio separately. Then input the video and audio from separate streams. Be sure the audio is 48k for DVD.

If your DVD authoring app will allow you to add video and audio in streams you should try that. TMPGenc will output streams.

Also, you may get better results by keeping the video bit rate below 8k and for stills 6k should look great. transistions could be a problem though.

I'd try some short video's with different bit rates and maybe even MPG or AC3 audio instead of LPCM.
Good Luck

Hi Unclebud,

thanks for the quick reply.

I've tried alot of combination of settings in TMPGEnc.

I've tried bitrates ranging from 8000 down to 5000 using 2-pass VBR, CQ (constant Quality) and Auto VBR. Still the same effect.

I've tried adjusting the bitrate in the Audio Settings tab ranging from 384 down to 192 kbps. Doesn't seem to make any difference either.

Anyway, I'll do some more testing and keep checking here for any clues.

Thanks.
