I assume you're using version 11. It's the only version that will edit iPad video. And I assume you've installed the latest version of Quicktime, per the program's requirements.
If you use Premiere Elements' Add Media tools to get the video from your iPad to your computer, version 11 will automatically set up your project to match your video -- so you'll get the highest quality possible.
To output the best quality for YouTube, use Publish & Share/Computer/AVCHD and select the preset for YouTube HD from the drop-down menu. This is also an excellent setting for saving your video for playback on both a Mac and PC.
There's no point in saving anything to a "higher quality" format. You can't add what's not there. Just use the right workflow and all will be well.
Meantime, be sure to check out my free 8 part Basic Training tutorials so you'll have an understanding of the basic moves for adding media and outputting your videos.
Thank you Steve ...Very quick response!
I just wanted to be sure that during all the editing I wouldn't lose quality.
I will check out the tutorials... its a case of running before I can walk...
Appreciated your help.
Just remember that, although this workflow will give you the best possible quality, YouTube is going to digest and re-encode your video anyway. And there's nothing you can do about that. It's the only way they can have millions of videos streaming from their site every day.
But this will give you the best possible quality. And ONLY with version 11.
