Hello,

I'm a newbie and I don't like to bother unless l have tried everything I am now at that stage.

Thanks for all the guides within which have allowed to reach the stage I am at.

Right my problem is on the audio it is slightly out of sync on the end product.

headac3he coverting to MP2 44HZ SURROUND 2 etc

Now this is the weird strange part I can't underdstand as the original ac3 audio did not have a delay on it so should be pretty straight forward but it was out of sync when playback on pc only very slightly.


So I encoded the audio with a 1 delay via Headac3he Playing back on Power DVD or even Media Player it is fine great but after then burning this to disc it is out of sync very slightly.

So I then tried and encoded audio with a -1 delay, again this plays fine via Power DVD and Media Player but when burnt to disc its out of sync again very slightly????

Now get your head round this how can both versions of the audio one encoded with 1 delay and one encoded with a -1 delay both playback in sync on Power DVD and media player??? They both can't be correct one has to be out of sync.

But none of then play in sync on the burnt disc burnt as a non-complient vcd via Nero.

Just to really confuse you the orginal standard encoded audio that I done before this with no delays etc because the original ac3 should not have had one played on Power DVD slightly out of sync but on Disc was closer to playing in sync than the two versions above.............. oh my god help I'm going for a lie down,

I am using Tmpeg to mulitplex basically putting the audio and video together could this be the reason?

Any help greatly appreciated.

Did you noticed than the delay in headache is given in MILLISECOND !
+1 or -1 are only 2 ms different, and for sure that is not enougth for your brain to make the difference.

Or are you talking about +1 SECOND and -1 SECOND ?

That can be (even if I do not have such problem on my standalone); You should use bbmpeg to see if that is better.

Uops, I hope you was just mistaken!
44.1khz in case of VCD and 48khz in case of KDVD

cause this would cause desyncing in further movie treatment defenitely.

O.K have tried bbmpeg which has not corrected the problem so that at least eliminates Tmpeg which is actually more straight forward to use for me.

So the problem lies between audio encode and the burn to nero,

Mmmm,

Try burning with VCDEasy to see if that helps.

Get the latest free version which is 1.1.5.2 here

I have also now encoded the audio at 48khz which again has made no difference................how come it plays in sync on Power DVD Media player but not when burnt to disc????

I will try vcd easy as it seems I have tried everything else and the problem must be at this stage of transfer....................''

will again report back so thanks for that mistermickster

Oh my god all because of (one tick in a box) in the process of encoding the audio in headac3he I was selecting the audio output to 44.1khz or I thought I was.

Looking at it again, on the drop down box there is a tick required to the left of it which as we know! tells it to select the option of 44.1khz from the drop down box.

What a banana only spent the last 3-4 hours working that out..........................''
