I would also consider redoing the information from the powerpoint slides with a graphics program inside FCP.
From my corporate experience many moons ago I fought many battles over presenters putting their speeches on the slides.
or they just fill them up with info, put it up for five seconds and move on.
When this kind of slide goes to video it might not be very readable. The bullet points will be very small.
Try it yourself. Take a slide with lots of info and try putting that in a CG and see how many lines of readable type you get.
Some graphics etc you might have to use, and can't replicate.
Depends on the use of the video. If its really is "shelf" material for the corporate world, then I might not sweat it. If it really is to be used for distrbution and lots of people will be asked to view. Then the PP slides may be a readable problem.
