Sync Audio with Slide transitions?
Author | Message |
I'm trying to get the Synchronize Presentation Narration to work accurately while having slide transitions. Here's my test setup: I have a 16 slide presentation with a 30 second audio playing across slides (the narration). I want to advance a slide automatically every 2 seconds. Each slide has a fade-in transition set to Fast (according to my calculations this takes 0.5 sec per slide). I perform the Sync task from the iSpring toolbar and click a slide every 2 seconds. Yet when I play back the presentation, the slides are lagging behind the audio (the original clicks), about 0.5sec (the fade-in transition) per slide. So when I get to the end of my 30 sec audio I'm only at slide 13 (which should be at the 24 second mark).

I would say the next regarding audio sync problems. Flash technology is not so accurate in synchronization complex animations and long sounds. There may be little shifts which depend on capacity of your computer and complexity of animation, effects and transitions that you apply in PowerPoint.

Well I am having the same problem and it is year 2013! I need to say that I am really getting frustrated with iSpring as its features are missrepresented. First, it is not so easy to use and second it does not work.

Thank you for posting here. Since 2011 synchronization tool has gotten a lot of improvements.

I would appreciate if you can e-mail me the troubleshooting guide.

it's now 2015 and I have just purchased iSpring River (old name: SlideAlloy) as I only need to sync prerecorded audio into Power Point Slides and then save to video or publish on youtube. These are basic slides with no animations and hardly any graphics yet I am having the same problems. When I rehearse the show and save the timings in Power Point it's perfect but as soon as I convert using iSpring River the audio start to lag behind the slides around half way through the presentations and get's worse towards the end. Very frustrated by this and need a fix as quickly as possible.
