Do you know of a good free converter that will allow you to keep sounds and effects?
I have have never used a PP to video converter. There is a lot of software out there if you search that does it.
Basically if you keep the file at a higher quality you are less likely to loose the sounds and effects. The file size will be larger, but I dont think this will be an issue if your goal is to put it on an ipad and not send out or upload ... (where you want a smaller file size)
