Synchronising Video and Audio
Ziris View currently only supports separate video and
audio files. Video and audio files, even when encoded
from the same source, can have a slightly different
duration. In order to keep video and audio in sync, the
audio duration must be adjusted to match the video
exactly. This synchronisation is particularly important
when repeating as the difference will accumulate with each
loop of the content The audio and video must also be
aligned on the presentation timeline.
Ziris Create allows the synchronization of the audio to
video by adjustment of the audio meta-data to ensure that
the two separate files match their start and end in real time.
No alteration is made to the source file.
This option is only enabled if an MPEG2 video and an
AC3 audio file are selected, and their durations differ by
less than 5 seconds.
To adjust the audio duration, select the two associated
audio and video files, right click and select "Set audio to
video duration" from the pop-up menu as shown below.
This option is only enabled if an MPEG2 video and AC3
audio file are selected and their durations are different by
less than 5 seconds. This does not change the audio file
itself, it just changes the meta-data. Ziris View takes care
of repeating the media based on the duration specified in
the meta-data.
