Are you trying to use your photos on the iPad and movies on the iPad within your iMovie for iPad app?
If so, your problem should be easily fixed by a privacy setting. The iPad protects the privacy of your photos and videos from apps unless you give permission to use them. You only have to do this once per app.
To fix this, click on Settings. Along the left side of the Settings, click on Privacy.
On the right side of Privacy, click on Photos.
You should see iMovie listed there. Turn it on.
By the way, this discussion group is for iMovie on the Mac.
If you have questions about iMovie on the iPad in the future, you may getter better and quicker answers here at the iMovie for iOS discussions.
