Audio problem

Post by skier-hughes »

This is driving me nuts........

Made a dvd and the audio on one of the tracks is all garbled when played on a dvd player (well 3 different ones).
Audio is fine on pc.

DVD is made up of three videos, all filmed at the same time, so school play, preparation, play and de-brief.

The prep and de-brief I've only used the audio from onboard cam. The play uses Audio from two microphones recorded to seperate tracks on one tape and the stereo audio from an on-board mic for ambience.

Settings are exactly the same as I've used for several years, as I have my own preset in WS.

I edit play in Edius, output from there using procoder to an m2v (vbr max 7500) video file and a wav audio file.

Import files into WS and use WS to make the ac-3 file, stereo 48khz 256kbs.

As I said the other two audio files are converted just the same and are fine.

I have remade two more dvds, just in case something went wrong with the conversion, and even packaged the project and used another pc to remake the dvd, with WS, and this still didn't work.

My normal burning route is to make an ISO, for future numbers, and burn from that.

The audio file from the dvd looks/sounds fine if I use Audition to look at it.
The audio sounds fine when previewed on my monitor from within edius.
The audio sounds fine when I am in WS, using pc speakers.
I've burned to Taiyo Yuden discs, my normal brand and also to Ritek G05.

I've burned another old project and that has gone fine.

The only difference between the prep/de-brief and the play is that the play audio is made up of 4 separate tracks, but when it comes out of Procoder it is just a normal two track stereo wav file.

I'm going to turn down the bitrate for the audio and try that, then go back into edius adn remove the tracks ansd make some audio files of the separate microphone tracks and the onboard cam to see if I can isolate which track is causing this if any, but any other suggestions?

I've made a dvd with audio set at 192.
I've made a new audio file in audition and used that, no joy.

Total size on disc is only 4gb, so it's not that it's filling the disc and baulking on the large file, the play is 1hr 15 mins the other 2 tracks are 2 mins and 14 mins.

I'm giving up today and will try again tomorrow.

I'm lieing, I've taken the two good files off and making a disc just with the play on it....
