Case examples
The fact that picture and sound are shifted mutually by a constant amount
is found in practice rather often. And there are countlessly many reasons
for it. Perhaps, the picture and sound recording were begun not exactly
at the same time, or during the treatment of a MPEG stream using incomplete
programs the time code contained in the stream got lost. Even on the modern
digital television - in contrast to Grandpas tough analogous technique
- a continual misalignment between picture and sound of a few frames can
be noticed not seldom. Usually here the sound comes slightly too early
respectively, more appropriately describing the cause, the picture comes
too late, because the MPEG coding of the picture is much more expensive
than the sound coding, and the video compression chip cannot make its
work timely.
The correction of such a constant picture/sound disalignment will be
our entrance project into the work with AV Adjust.
