I cannot reproduce the scenario. I tried adding many slides, added text and applied animations to them.
I recorded some audio and tried to sync them to the animations. The output rendered by presenter seemed to be as expected i.e i could not
see the animations running too quickly.
It will be good if you can specify what animations did you use in your presentation.You can also share the presentation if possible.
Else please list the specifc steps you used to produce it.
Many thanks for your response
The animations are simple entrance and exits (faded zoom in and out)
I have even created a shorter version (basically deleted the last few slides) to see if this is a size issue but I get the same problem
How can I get the presentation to you? It's 4.38mb
