> a drift in sync is not only possible, it's probable.
I'd go as far as to say *inevitable.* I've created videos with MIDI files
for music (small and compact) and digital photos for imagery (large and
pixel-laden), and have experienced drifts of as much as four seconds in a
two-minute video. If tight sync is important, there are three things to
consider:
1. The first time you play the video, you might see the most drift, before
the images are cached onto your drive. I counsel clients, if at all
possible, to run the entire video once right before playing it for real.
2. If there are certain passages that MUST be in sync, you're best off using
several audio clips instead of one big one. If your content allows for it,
fade out one and start the second one as close as you can to where precision
sync is needed.
3. If your standards are higher than this, leave PowerPoint and head to a
true production application.
