Problems when converting AVI to DVD mpeg2

[Tiger123]

Hi,
I'm a newbie to all this conversion. I have an .avi movie file that I want to burn on a DVD but I know i have to convert it to DVD mpeg2 first....so I used TMPGEnc Xpress and tried to convert a sample of the clip (ie. 10 seconds) to see if it works........however, but the video is out of sync...it is lagging and slow but the audio is fine........what's wrong? how to fix this?

does it have anything to do with the bitrate? I saw it was set at like 9200 so is it set too high and that caused the slowed down video? I just kept on clicking next and left the default settings.. what is the bitrate I should use when converting avi to dvd mpeg2.

please help, thx

You have to convert it to MPEG2 first and then author a DVD. The authoring process multiplexes the video and the audio and any subtitles together. The max bitrate for all of these "streams" is 9800 kbps. If you are using LPCM audio which is approximately 1536 kbps, then the max rate that you have for video is approximately 8200 kbps. If you are authoring a DVD-R, then total bitrate should not exceed about 7000 kbps. This is due to the fact that a DVD-R will have more errors, or be slightly harder to read, than a stamped DVD.

How were you playing back your 10 second clip when you noticed the lagging video? From the hard drive? From a DVD? What player?

As far as the bitrate is concerned, the calculator that I use is located at http://dvd-hq.info/Calculator.html, but there are many others out there. Some are probably listed under the Tools category at the left side of this screen.

How do i find out what audio I am using? (ie. if it's the LPCM audio that you are talking about?)

How did I play the 10 second clip?
IN TMPGEnc xpress, I selected only 10 seconds of the clip to convert from avi to dvd mpeg2, then when the conversion was done, I clip on the "preview output" button and saw that the video lagged while the audio was fine......I also tried playing it with powerdvd and same problem (laggy video, audio was fine)...so i played it from my hard drive.....

do you think that if I lower the bitrate that everything will be fine? thx so much....

How about some specs on your avi file? It could narrow down the issue quickly.

Hi,

You can use gspot and post the information of the codecs used. (you don't have to show the file name )

ok....i'm posting info about the avi file.....i couldn't find gspot so i'm just posting the file info from virtualdub.....is that ok?



so there's the specs on my avi file.....i selected a 10 second sample of the clip and processed it to dvd mpeg2 using tmpgenc xpress with all the default settings.....all i remember was the bitrate was 9200 (is that too high for the specs of my avi? i'm guessing maybe that's the problem?).....then when i preview it the dvd mpeg2 file (from harddrive) using powerdvd or the "preview output" button on tmpgEnc xpress, the video is lagged while the audio is perfectly fine.......

pls help.....i just got a dvd burner lg GSA-4163B for my birthday and it's my first time burning a DVD.thx :P

Your audio is mp3. If you use virtualdub to save your audio as an uncompressed .wav file (file>save wav, with audio>full processing mode checked via your menu options), you can then combine the video and audio in tpmegenc, and it should correct the audio sync. There are a lot of guides in this forum that step you through it. Just search under avi to dvd.
