MPEG options
There are three options to choose from when saving files to MPEG in EnhanceMovie: MPEG-1, MPEG-2, MPEG-4. Decoding and playing an MPEG file is generally harder on system resources than decoding and playing an AVI file, a factor that makes choosing the correct media type very important.
MPEG-1 Media Type files are generally easier on system resources and smaller in file size than other MPEG Media Types. An issue that must be considered when selecting an MPEG Media Type is the CPU speed of the system that will play your videos. For example, even slightly older Pentium systems (such as those with CPU speeds under 350 - 450 MHz) cannot reliably decode and play the MPEG-2 media type. However, MPEG-1 can be decoded and played on just about any Pentium (or generic Pentium) computer. Playing MPEGs on 486 machines is possible, but special software, and at times special hardware (depending on the system setup) is required.
MPEG-2 is a newer, more flexible, and more powerful MPEG Media Type. The quality of MPEG-2 can be so good that it's the file format used in DVD and digital satellite television. The most significant downside of MPEG-2 in terms of use on the Internet is system resources: MPEG-2 requires at least a Pentium 350 - 450 (or generic Pentium 350 - 450) CPU for reliable decoding and playback.
MPEG-4 is designed to deliver DVD ( MPEG-2 ) quality video at lower data rates and smaller file sizes. While audio and video are at the core of the MPEG-4 specification, MPEG-4 can also support 3D objects, sprites, text and other media types. MPEG-4 allows the use of different encoding methods, for instance a keyframe can be encoded using ICT or Wavelets resulting in different output qualities.
MPG can be either an abbreviation for MPEG or is used as a file extension for MPEG-1 and MPEG-2 video data.

NTSC (NTSC Film)
Mbps = million bits per second *2 approximately resolution, it can be higher or lower ~ approximately bitrate, it can be higher or lower a DVD with lower video quality, similiar to VCD/SVCD video quality * the video quality depends on the bitrate and the video resolution, higher bitrate and higher resolution generally means better video quality but bigger file size
