Im using premiere elements 12 its my first time using any adobe editing software. I bought it because I was losing quality in my images and video while making videos on my basic movie maker that came with my laptop. I spent over 100 dollars on elements and im getting the same results. do I need to tweek my project settings? I want to upload this video online will it go back to normal once uploaded? any tips would be appreciated!
You don't say if you are working on a high-def or a standard def (DVD) project, but do remember that Premiere Elements is a video editor, not a slideshow creator. So anything you put into it is going to come out at video resolution -- 720x480 pixels for standard def or DVD video or 1920x1080 for high-def or BluRay video. That's likely a big step down from your original photo resolution, since even 5 or 10 megapixel camera is shooting many times that resolution.
This article explains in greater detail the difference between photo and video resolution.
Where do you plan to display your slideshow? If on a TV, Premiere Elements' resolution is just fine. (Assuming you've got a BluRay workflow for your HDTV, etc.)
If you're looking for a higher resolution slideshow creator for, say, display on your computer, you may want to consider a dedicated slideshow creator like Pro Show Gold.
