EDIT/ Think I've figured it out, don't know why but my videos were imported as photos to my ipad so they were showing up as photos (ie with no file name). Seems I need to keep videos out of the camera roll and keep them in VIDEOS. That said though when exporting a video from iMovie it only gives me the option to export the movie to CAMERA ROLL (which is evidently not where it should go??) The only way I can see around this is to copy my movie from my ipad to my laptop then import it back to the ipad via iTunes as a movie!
How on earth do I give my videos a name that will show up in photo album? Have tried importing direct from memory card and also through iTunes but my videos never have names (which makes it hard to know what they are until I open them). Help appreciated :-)
