Premiere Elements has problems with video recorded with a device that records with a variable frame rate. Such devices include iPad. The typical workaround is to take your iPad video into the free HandBrake to obtain the H.264.mp4 with constant frame rate version to take into the Premiere Elements project.
The symptoms of this problem range from audio out of sync to not being able to import the video at all into Premiere Elements.
To confirm that you are actually working with this variable frame rate condition, you can take your iPad video into the video audio properties read out program named MediaInfo and observe if the video properties include 3 instead of 1 frame rate - free Media Info Mac can be found http://mediainfo-mac.en.softonic.com/mac
Be careful with your choices in downloading and installing since MediaInfo has been known to travel at times with unwanted baggage.
When you are setting up the Video Tab options in HandBrake, please type in the frame rate rather than leave Same As Source. And, be sure to dot the Constant there to select it.
Please consider. We will be watching for your results as your schedule permits. If any questions, please do not hesitate to ask.
I checked the rate on Media Info and it was a variable rate. I processed the files with Handbrake and they worked fine.
Great news. Great job.
Follow up with outcome is appreciated.
