Cubase PRO 8's manual, some questions

Hello there, I’m Nataly. I was looking for the Cubase Pro 8’s version, but I didn’t any complete manual, so, I have some questions, because I’m trying to compare Logic Pro X and Pro 8 of Cubase. Don’t know what is better in a matter of simultaneous tracks for 48/96 and 192kHz. Besides, how many inputs supports maximum Cubase to comparison LP X?

In matters of postproduction, you can work with video?

Where I might find this information? manuals are about quick start, I find a consistent advantage of the Pro version of Cubase front of Logic because of this.
