No sound after authoring home movie

[Commander XJL]

After capturing from my DV camera into Premiere, then encoding the AVI file in TMPG with the DVD template, I then brought the MPEG2 file into Spruceup and authored the DVD. The problem is I get no sound unless I play on an Apex or the computer. Spruceup never complained about the MPEG2 file or gave me any error messages. If I demux the MPEG2 and bring the seperate files into Maestro, after authoring Maestro gives me an error I don't have a PCM or AC3 track. For home movies I would rather just use Spruce, but what do I need to do differently so I get sound on all DVD players? Do I need to use a different setting in TMPG?

Are you saying that you are authoring with MPEG audio as your soundtrack to go with your .m2v? If so, be sure you are not authoring for NTSC, since only PAL offers (limited) support for MPEG1-Layer2 soundtracks. If this is not relevant in your particular case, then please give me more detail.


Arky ;o)

ya I'm saying that after I encode the MPEG2 file I bring it into Spruce and author and it was for NTSC. So if this type of sound file won't work, I suppose I have to demux the MPEG2 and convert to PCM? Didn't want to have to do that since the file size is bigger. Any other better ways?

[Arky]

Well I agree about the .PCM filesize, so why don't you encode your soundtrack to .AC3 ? NTSC fully supports .AC3, as does PAL. Simply prevent TMPGEnc from ever encoding your audio, and instead use an NLE (everyone seems to use Premiere...) to output a PCM .wav file. This can then be imported into your .AC3 encoder of choice.


Arky ;o)

Could you tell me more about how to create a AC3 file? Is Besweet the only app that will transcode a PCM Wave file into AC3? And are you saying take my original AVI file and export just the audio track as Wave (from Premiere)? Then convert to AC3? And can it be done without Besweet?

[TRILIGHT]

WAV -> AC3 AFAIK...

BeSweet
SoftEncode
Scenarist

Whenever I convert the wave files to AC3 and author the dvd with maestro the disk plays on my Apex but freezes on my Pioneer. If I author the disk with the wave files it plays fine on both. I totally don't understand why this disk won't play on my Pioneer. Maestro and my burning software doesn't make any complaints. There is something about that converted sound file that my Pioneer doesn't like, that much is certain

I have tested this thorougly, and have come to the conclusion that my Pioneer Player (DV343) will NOT play a DVD authored using BeSweet AC3 encoding. I have tried many different settings within the software. The same exact DVD using the original mpa file (instead of the AC3 file) from CCE WILL play in my DV343 Pioneer. I know someone else who has the same model, and it does NOT work on that one either. It's only this Pioneer model though. I know people with other Pioneer models which it works on. I tested the same disc (with AC3) on about 20 DVD players in Best Buy and Circuit City and they ALL played fine. Have to find a different encoder or something.

You are not alone, dplehnen. I have come to the same conclusions with my Pioneer DVD-343.

hi guys,
i heard there are playback issues with 2.0 AC3 streams created by ac3enc.dll (using BeSweet/AC3Machine).
ac3enc is taken from the ffmpeg project, and one of BeSweet's users have sent a bugreport to the developers :
http://sourceforge.net/mailarchive/forum.php?thread_id=1558796&forum_id=1506


btw,
is this bug only exists for 2.0 AC3 streams ?

[TRILIGHT]

Hey DSP! Remember when I mentioned having some distortion in dynamic passages when using the tool for mpa->AC3? Just thought I'd include an FYI that the encoding I was trying to do was DD2.0 as well.

[DSPguru]

hi TRILIGHT :) ,
if i recall correctly, you reported crackling sound, and this issue had already been solved some time ago.
if you have some spare time, please set-up a small test with latest BeSweet.

I'm experiencing the same problem with Pioneer 525 and c503. Works fine on my pc and Sony 655p.

As soon as audio track starts playing both DVD players freezes. FF is possible. Jumping from chapter to chapter is possible to. It plays for 2-3sec and then stops.

Software used: Maestro 2.9; cce 2.5; BeSweet 1.5b1, ac3enc.dll dated 7/20/02 2:08pm. (Installed from Doom9's D2S110B1 (s)vcd bundle.)

Is there explanation for this problem and maybe workaround?

If I can recall, using mp3(44.1)->mp2(48) have the same effect on Pioneer’s players.

Please, Please Help... :confused:

Finally had a chance to use Soft Encode for my AC3 streams and everything works perfectly now
