Avi > DVD timing issues

[dragonnick]

Ok, so I'm putting some .avi files onto DVDs to watch on my TV. I used Avi2Dvd for the conversion, and then I used ImgBurn to put it onto the DVD.

Ok, my problem. The beginning is great, perfect, dead on everything. But then as it gets closer and closer to the end of the DVD the timing gets worse and worse. At 30~ minutes the timing is about 2 seconds off (audio ahead).

I have looked at guides to fix timing issues but my situation is always different than the guides and they never work.

Can anyone help me?

Thanks in advance.

How long is the program??? If it doesn't happen until the very end of the last program it could be bad media. You could try a different brand of blanks to see if that clears it up. (many users report problems at the end of dvds and that is a symptom of bad discs at the edge of the dvd)

Don't use 'all in one' tools...
You can:
Extract the audio as elementary stream with virtualdub
Convert the audio to mp2 or ac3 with besweet
Convert the video (only!) with Tmpgenc or avisynth/HC
Use an authoring program (TDA, dvdlab, GfD, dvdauthorgui...) to create the DVD structure from the elementary video and audio streams
Burn with nero or imgtools/imgburn

Hmm, good tips.

The time length will be the entire length of the disk, so 120 minutes or whatever, but noticeable timing issues occur at about 25-30 minutes in. Further it goes, further it's off.

I do not think it is my DVDs, I do not doubt it's my "All-In-One" programs though. I just searched for some crappy free things. So it might be them.

However, I read a guide that said all timing issues are because of the computer or something. The sound card maybe? Anyway I dunno, anymore tips will be great, I may try to use those other programs later.

The sound card maybe

I don't see how that would be possible. Its the encoding that screws up not the hardware playing it.

Try a sample with another batch of conversion programs and you should get better results. Also it never hurts to use name brand discs

I have the same problem, i really fed up now of timing probs,i use divxtodvd and nero to burn it, soon as i convert the files to dvd, the mess up, can some please post a quick step by step only using a few programs and not time consumimg!

Thanks..

You can use a program like tmpgenc to convert to dvd. If you have a 5.1 digital track seperate out just the video and convert it to dvd standard mpeg. Than you can author the video and audio with a program like tmpgenc dvd author or another one that accepts seperate audio and video files for authoring.

Otherwise tmpengc will output an mpg file with mpg audio thats ready for authoring and shouldn't present any problems - provided you use decent media.

I have the same problem... can some please post a quick step by step only using a few programs and not time consumimg!

Thats contradicting itself! If there would be something like a 'quick step by step only using a few programs and not time consumimg' then why not put this 'quick step by step' into some lines of code and using this script all the time? Because it's not possible... Depending on the properties of the source material there is a bunch of programs to convert/correct/adjust it (often different programs for audio and video) so that it can be finally burned on a DVD. No 'all in one' program can cover all possible 'stumbling blocks' that a particular source may have.

Extract the audio as elementary stream with virtualdub

I have Virtual Dub and I'm not seeing how to extract the audio as an elementary stream. Or how to extract it at all >_> I just say "File" > "Open Video File" and pick my .avi, but then I don't know what to do. If you see this I'd appreciate it if you could guide me further but I'll keep looking.

Convert the audio to mp2 or ac3 with besweet

I assume this is because Virtual Dub extracts audio as not one of those file types? What is the file type of the audio on a DVD? I thought mp2 was the music on the menu, but I may be wrong. I don't recognize ac3, that may be the audio of the actual video.

Convert the video (only!) with Tmpgenc or avisynth/HC

Now, using TMPGEnc I see a spot to choose the video source, but does that mean I have to use a video-only file? I do not know how to get the video by itself, the program I have for demultiplexing (I believe is the term) only does that to .mpeg, not .avi like I am using. In other words, how do I get an elementary video stream from a .avi file with both video AND sound on it?

Thanks in advance for the additional help

Just open the AVI in TMPGEnc and let it encode both audio and video to a program stream meeting DVD standards.

I have *never* had an A/V sync problem with TMPGEnc.

HTH,

@Capt.Video

Just open the AVI in TMPGEnc and...I have *never* had an A/V sync problem

If the avi has VBR MP3 sound you will... Maybe it's better with TMPGEnc 3 (Express), I still use the last 2.5 version.

I'm putting some .avi files onto DVDs...

Avi is a container for very variable content. It may be video or audio or both encoded with uncountable codecs (or even uncompessed).

have Virtual Dub and I'm not seeing how to extract the audio as an elementary stream.

Look here:

Convert the audio to mp2 or ac3 ... I assume this is because Virtual Dub extracts audio

Virtual Dub can extract the audio only (using 'Direct stream copy'), or convert to (uncompressed) wav ('Full processing mode'). If the source audio format (within your avi) should be mp2 or ac3 already (very unlikely), you are finished with 'Direct stream copy'. Otherwise you (should) reencode to AC3 or MP2. This can be done with BeSweet (use the newest beta!) from either the 'Direct stream copy' wav file (probably mp3 inside a wav) or the 'Full processed' (uncompressed) wav file.

Now, using TMPGEnc I see a spot to choose the video source...

You need to choose the output format as well. There you can select the 'Stream type': ES (Video only)
Using this setting, TMPGEnc will just encode the video, save it as elementary video stream and ignore the audio.
