They are in VOB and UDF formats. Can I import them to Premier elements 10, and can I fix or enhance different scenes ie increase the contrast on some and the light on others etc.
VOBs, yes. It's not the ideal format, but it will work.
Make sure your project is set up for Hard Disk Camcorder video or you'll run into problems later though.
You'll likely need to render often as you work with this format. So, whenever, you see red lines above the clips on your timeline, press Enter so that the video can render (the lines will turn green).
