You don't say which version of the program you're using, so I can't give you exact specifics -- but your keyframed effects are done in the Applied Effects panel, opened by clicking the button on the toolbar on the right side of version 15.
In Applied Effects, open the Motion effects and then open the keyframe control workspace. You can then creating zoom animations (Scale) as well as rotation and position animations. You say you've watched a lot of YouTube tutorials, so you should have an idea how to open this workspace and create animation keyframes.
As for applying a transition to multiple clips at once, you simply select a group of clips or stills on your timeline, right-click and, from the Timeline sub-menu, select Apply Default Transition (which, by default, is the cross dissolve).
I'm sorry I put the version in when I tagged it, it's Elements 15. I did try playing with the Applied Effects but had a hard time using it. How exactly do I do what you recommend? I have watched tutorials but they didn't help me much Windows Live Movie maker was so simple and this program seems like it's much more time consuming, I hope its because I'm just learning. I figured out the transition issue thanks to your advice, thank you!
Well, MovieMaker is a very different program. It may be simpler, but it's much more limited.
Premiere Elements' keyframing tools quickly became second nature to me.
You keep saying that you've "watched the tutorials" but I'm not sure what tutorials you've watched or who made them.
Check out my free "Basic Keyframing" tutorial on my site Muvipix. It's for version 12, but the principles are exactly the same for version 15.
