Why am I having audio problems on this DVD project?

[kschang]

I obtained an AVI which had VBR MP3 as the soundtrack.

Attempt 1: Auto convert using AVI2DVD, the resultant DVD plays fast/slow/fast/slow. Useless.

Attempt 2: Saved soundtrack separate from AVI using VDubMod. Convert to AC3 using Belight (48K sampling rate and all that) Used GUI for DVDAuthor to combine it all and author it back into DVD structure. Result again: fast/slow/fast/slow.

I *think* it's the AC3, but I can't seem to convert it right. Belight showed no errors, and MPC seems to play it just fine.

Attempt 3: Went back to VDubMod, did "full processing" this time and saved the soundtrack as uncompressed PCM wave. Got a HUGE file this time (like 1.6 GB) so it looks right. Used Belight to compressed this into AC3, 48KHz, and all that. Got a 400M file, so I guess that's about right. Used GUI for DVDAuthor to combine it again. And decided to read the log this time. HUH?

During the authoring phase, EVERY sector of the audio reported a warning about audio out of range on EVERY LINE? It finished just fine. Got a DVD this time that burns fine. However, when I play it, the sound cuts in and out, in and out. The dolby light goes on for a few seconds, off for a few seconds (no sound) then back on, so on and so forth (on the DVD player).

The warning was:

WARN: audio sector out of range: -xxxxxx (vobus #xxxx, pts xxxx.xxxx)

It's doing this on almost every vobu (vob unit?)

What should I do?

[kschang]

NOTE: At the end it says

WARN: audio sector out of range: -1120268 (vobu #15870, pts 4863.4934)
STAT: fixed 15871 VOBUS
INFO: dvdauthor creating table of contents
INFO: Scanning C:\Program Files\GUI for dvdauthor\OutDir\DVD/VIDEO_TS/VTS_01_0.IFO


So I guess those warnings don't mean anything, but why doesn't the DVD, when burned, play right?

Uh, did that. (See attempt 3)

AAC not going to work to make a dvd - and mp2 doesnt work on all dvd players

[kschang]

Argh! This thing is KILLING me! (almost)

I have ONE AC3 file that is playing properly (plays in sync with the m2v) (incidentally, it's 5 seconds longer than others, weird...) and I'm going to try to convert THAT to MP2, then mux that with the GUI...

[kschang]

Dang, this is WEIRD. Burned a new DVD with the MP2 as sound track. PowerDVD plays it fine.

Put the same DVD in the DVD Player (Pioneer 525, old but good) and it does the same thing: sound cuts in and out, in and out, in and out.

Thought I had a bad authoring program, so I tried SimplyDVD, which is like a ultimate simple GUI to DVDAuthor... But that DVD, with MP2 sound track, also did the skipping sound thing.

So far, I've had 6 coasters. It's NOT the media since it plays fine on the PC, and I've tried both Imation AND no-name Staples media (which has FUJIFILM03 media code!)

Any other ideas?

have you checked your bitrate of your mpeg file?

[BJ_M]

oh - ok .....

wav is the best choice instead of more lossy formats - but i see your drift ..


funny enough ... it is a lot of the pioneer players that do not play mp2 audio

[kschang]

have you checked your bitrate of your mpeg file?

M2V is fine. Actual size is under 4 gig, bit rate average is about 3700 (max is 8000, right?) compressed with HCEnc, originally through AVI2DVD.

It's the audio that's killing me.

Any way, I got so tired I went ahead and downloaded VSO Divx to DVD and used that (and that worked just fine, bless VSO), and the DVD just burned... Putting it into DVD player now... Works just fine. *sigh* 8)

[BJ_M]

8000 is often to high for some encoders and media combinations .. for burned media ... 8000 would have been for sure to high with the wav files .... i suspect it was (in part) the video files that were causing the drop outs in your audio files -

with out a sample - it is only guessing at this point ... but this is not an unusual thing ...

[kschang]

I figured out the problem. AVI2DVD is VERY VERY VERY picky about the file names. You have to take out the extra periods, dashes, parens, and so on.

[Black Shadow]

I've taken out the extra periods, dashes and all of that but I still have the same problem

in the bigenning it seems fine but after a while "the out of sync problem" comes again

I really liked avi2dvd because it converts in exellent qualities
I tried convertxtodvd but the result is cheap quality even if I choose the high quality option

so is there any way to solve avi2dvd problem ?

[mats.hogberg]

Quite frankly - after years of AVI to VCD/SVCD/DVD hazzle (a hit&miss procedure at best, as AVIs are rarely encoded with the conversion to other formats in mind, in the first place!) I got a DivX capable player. Never had any reason to fiddle days on end with stubborn conversions since that day. A 30 Euro investment that saves you a lot of trouble and time.
