This is weird ?

[Joef2k2]

Right, to my previous post about audio delay, i managed to fix the out of sync part within the video, so now its all fine and looks as near good as it can be.......but now i come up with another problem, when i burned it to a dvd disc and played it on my dvd player, the audio sync seems to happen again just after a part in the video where it seems to stutter.........but this did not happen when i viewed it in powerdvd, i burned the copy 3 times and it done the same at exactly the same part....... Now is this because its possibly a bad frame ? but if that was the case, then why didnt it happen when i played it back on my computer ? im confused with this one so any help would be much appriciated !! thanx

What bitrate did you encode with?

My guess is that it may have been too high.

This isn't the only possible reason for the symptoms you describe, but it is the first thing I would check.

Your player may not be able to read enough data off the disk before the buffer runs out.


Arky ;o)

Using Power DVD, If you right click in the main window, when playing a movie, you should see an option "show information", this will tell you what you need to know, Audio/Video type/bitrate etc.

3 things in the above information worth a mention...

Bit Rate : 2.48Mbps

This is a bit low for DVD, but shouldn't cause any problems...

Number of Audio channels : 6
Bit Rate : 192.00 Kbps

192 kbps divided by 6 channels = 32 Kbps per channel, which is BAD, the bitrate needs to be at least 384 Kbps

Source picture resolution : unknown = 4

Knowing this would be useful... 8)

ummm if im correct the picture resolution is 480 x 576 ? if thats wot you mean by that ? so the bitrate is way to low at 192 ?

Yes, the audio bitrate is too low for 6 channels, as for 480x576?, that isn't a compilant DVD resolution, if it works in your stand-alone player, then thats purely by chance... For PAL use either 720x576 (MPEG2), 704x576(MPEG2), 352x576(MPEG2) or 352x288(MPEG1 at 1700kbps).

Just to clarify, are you burning to CDR's or DVD's

[Joef2k2]

so if it works on mine? thats not to say that it will work on all other DVD players ? it also works on my PS2 aswell. and i am burning DVD's not CDR !! when u say its not a complaint resolution ? how do i go about changing that and will i lose any quality ? and as for the sound ? would u suggest i change the bit rate then ? and this may solve the loss of sync once burned to a disc?

1) Weird Problem

2) Help!

3) Help, Urgent!!

4) Out of Sync on DVD but not on computer

Which of the above is a good subject line? (for the answer see this forums faq)

[mh2360]

presto, your post helps HOW?

I think you had better start from the begining, as i didn't see your previous post....

[Joef2k2]

lol i was actually going to say the same myself but didnt think ide be that nasty........ atleast people with more knowledge then me about the problem are trying to help or give me solutions........then u get presto who decides to take the piss.........if you aint got nothing to say then please dont reply back........ people that do try help, i appreciate it
