So far Sony Vegas is good for me…?

I must know if it can do these number of things in advance of I buy it:
Hasten and reduce the video
Capable of put photos when using the video
Can narrate through video in addition to photos
Anything else on my checklist as well as so yes…
Jeez MY PARTNER AND I ask loads of video editor questions…:)

Speed in place and decrease the training video…Yes
Capable of put photos when using the video…Yes
Can narrate through video in addition to photos…Yes.
