Setting Manual Exposure for Nikon D5100 in Movie Mode

www.learningdslrvideo.com I want to do a shoot out between the Canon T3i and the Nikon D5100 but I hit somewhat of a road block on setting the exposure for video mode for the Nikon. I did a lot of research around the web and it appears you can manual set exposure for the D7100 but not D5100. However it appears in the video that I got it to work. If there are any Nikon people out there that know if I did this correctly let me know.
