NRG
Files with nrg extension are used for the default disk image format in Nero Burning ROM software. NRG is not just "renamed" ISO image, but proprietary format used by Nero. However both serve the same purpose, ie. physical media backup and burning.
MP4
An mp4 file extension is typically used for MPEG-4 multimedia files defined by ISO 14496-1 standard. Commonly used for video and movie files and supported by vast number of media players.
