I have been using this program for years, with my upgrade to PowerDirector 11 I've discovered that I can do a lot of editing, but I am struggling with learning the tricks of doing that with this program. Hopefully those that are in the know can help me. Three initial questions:

Question #1
If I want to make a jpeg in Photoshop to then use in a video that I'm producing in 16:9 what size should I make it. Obviously it isn't 16x9 pixels and I suspect it isn't 16x9 inches either. What should I set my image size in Photoshop to get I nice undistorted picture in my video?

Question #2
I want to make a title. I think I know how to do what I want as far as: add text, add background, add beginning and ending transition but what I would like is to add an animation of a quick sparkle in a specific location. Like if I had gold lettering and I wanted an animated sparkle to shine for a couple seconds off of say 3 points on the title at slightly different timing and only for a partial time the title was active - text come in, sparkle, text leaves, transition. Can I do such a thing, if so where? how?

Question #3
I would like another title that slides a box (or other graphic element) in, text appears on box, box transitions out. There are some templates in the software but they are not what I want in style and/or color and I can't seem to find a way to change the box size, style, animation or color.

Thank you in advance for any help
