Delay mean before or after?

[Dirk99]

Hallo,

when I demux the ac3-files from the vob-files using DVD2AVI the ac3-files sometimes have a delay. What does a delay of 79ms mean? Is the audio 79ms before the video or is it the other way?
I´ve searched this in this forum on this simple question about one hour, and haven´t found an answer. :(

Thx,
Dirk

a delay of +79 ms means the audio starts after the video by 79 ms
a delay of -79 ms means the audio is ahead by 79 ms



(and you made me doubt for a second there :D)

Thank you!


I know it is a very simple question, but in almost every program to encode a video you only have to enter the value and the program thinks instead of the user...
