Hi there, first post

Just wondering if some effects i did easily in 6.0 can be done in Pro

In 6.0 i used 2 black videos and one regular video to make the letterboxes 'grow'
is this possible in Pro?

Also is A/B editiing still available in Pro?

And finally in 6.0, the motion settings came with a preveiw box, and is this there in Pro, cuz i really liked the preview box, it let me make the 'growing' letterbox effect

(these questions might be obvious to some, but i havent explored pro)
Thank u to any one who responds!
