To use the system object to determine this value, you will have to read through the entire file like this:

vfr = vision.VideoFileReader;
numFrames = 0;
while ~isDone(vfr)
    step(vfr);
    numFrames = numFrames + 1;
end

The VideoReader object has a property called NumberOfFrames that you can query for this value. Starting R2014b, the doc says that this property is being deprecated. However, its been 3 releases but its still going strong.
