I just became a forum member so it may be too late for you to use my input about your post last May. You can create your video directly from Keynote on a Mac (I don't know about iPad because I don't have one.) Simply record your presentation, including any sounds you may have added, by going to Play>Record slideshow. You could do a voiceover while recording your slideshow. It will save as a .mov file, which should play on the iPad (again, I don't know myself.) Alternatively, if that doesn't play on your iPad, there is screen capture software called SnapzPro (about $60) that will record your Keynote slideshow, including a voiceover, and save it as a .mov file. You could then change this file type to another file type, using a free download, that would be accepted by iPad. I have found the .mov file created by Keynote has other scripting in it that doesn't convert well but the SnapsPro .mov file is clean.
