This represents the worst possible situation with regards to
interleaving. During playback, the system will need to seek back
and forth within the file continuously in order to load the audio
associated with the video as time progresses. If the viewer were
to jump to a specific point in the video it might be hard for the
media player to quickly locate the corresponding point in the
audio stream, causing an undesirably high seek recovery time.
Now consider the corresponding correctly interleaved file:
Here, audio chunks are interleaved within the file so they fall closely
alongside the related sequence of video. As playback progresses
seeking within the file is minimized, and in fact with appropriate
buffering as provided by most devices seeking will not even take
place. This leads to smoother playback performance. Because
audio chunks are stored alongside the corresponding video
chunks if a viewer skips to a particular point in the video the
media player will likely locate the associated audio and resume
playback more promptly.
Using VirtualDub, you can access the Interleaving options from
the AUDIO menu.
