Synchronize MPEG and WAV in PowerPoint 97

[bsmith]

I have a mpeg video and wav narrative in ppt 97 that I added using the
insert movies/sounds. Since the video contains someone talking, it is
important that the audio is in sync with the video.I created three
slides and on each slide I added the video/audio using the insert
movies/sounds from file. I used the custom animation, but had to
change the animation order for the MPEG/WAV on each slide to keep them
syncronized. I can syncronize the audio/video using the custom
animation on a computer, however, when I copy the presentation to
another computer, it is out of sync by 1 second. Is there any way to
syncronize the video with the audio permanently in powerpoint 97?

I do not have access to the software that created the MPEG and WAV
file.

My video is 5 min 30 sec. Is a 30 min video too long?

Hi Belinda,

Timing in PowerPoint is tied to the cycles of the
processor on the PC instead of actual seconds on the clock.

That's why you're having problems when you go to another
PC. You'll need to use a sound editor to combine your
sounds to get them synchronized.

HTH,
Glenna

Hello,

PowerPoint 2003 doesn't support the kind of timing/synchronization that you
are looking for. For media we can only synchronize the beginning of the
sound to another event. We can't control the beginning of other events
based on how many seconds of a media file has been played. The feature for
this degree of timing control is just not built into the product. This is
mostly because two completely different architectures are used. For
multimedia playback we use system API calls (PowerPoint has very little
control over what happens after the media has begun to play) while
animations and transitions are controlled using PowerPoint's built in
procedures.

So, for example, if you want to sychronize animations and transitions with
something other than just the beginning of media playback (on same slide or
over multiple slides), you will get inconsistent results from system to
system or even on the same system (depending on what data is still cached
in virtual memory).

If some kind of more deterministic, system independent, multimedia
synchronization with animations and transitions is important to you (or
anyone else reading this message) for Microsoft to consider for some future
version of PowerPoint (or if it's not possible, perhaps features within
PowerPoint to help you avoid trying to sychronize something that we can't
guarantee will always be synchronized), so you don't have to resort to
exporting to other formats (movies, shockwave flash, etc.), which would
result is some loss of formatting and/or fidelity, don't forget to send
your feedback (in YOUR OWN WORDS, please) to Microsoft at:

As with all product suggestions, it's important that you not just state
your wish but also WHY it is important to you that your product suggestion
be implemented by Microsoft. Microsoft receives thousands of product
suggestions every day and we read each one but, in any given product
development cycle, there are only sufficient resources to address the ones
that are most important to our customers so take the extra time to state
your case as clearly and completely as possible.

IMPORTANT: Each submission should be a single suggestion (not a list of
suggestions).
