Adjusting the size of slides to match screen recordings?

Hi Kendal, 

Thanks for the great advice! 

I'd originally asked for the screen recoding to be 1920x1080/ 16:9, and had tried to import that into a 1920x1080 or varying different sizes of 16:9 slides, and still have that whitespace on varying sides. 

I'll ask the client to confirm the size they'd sent, and perhaps ask them to record a few different variations and try to get them matching and to the bottom of it that way.

Thanks again!
