MPEG-1

Audio and video compression format developed byMPEG group back in 1993. Official description:Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s.

MPEG-1 is the video format that has had some extremely popular spin-offs and sideproducts, most notablyMP3 andVideoCD.

MPEG-1's compression method is based on re-using the existing framematerial and using psychological and physical limitations of human senses. MPEG-1 video compression method tries to use previous frame's information in order to reduce the amount of information the current frame requires. Also, the audio encoding uses something that's calledpsychoacoustics -- basically compression removes the high and low frequencies a normal human ear cannot hear.

Resolutions that video streams can use, are:

352x480(NTSC,MPEG-2 &MPEG-1)
352x576(PAL,MPEG-2 &MPEG-1)
352x240(NTSC,MPEG-2 &MPEG-1)
352x288(PAL,MPEG-2 &MPEG-1)

TMPGEnc 4 - MPEG-2 and MPEG-1 Video Settings- The original Tsunami MPEG encoder was one of the first to be clearly geared toward the consumer market instead of being designed for inclusion in other software or use by video professionals. Because of this unique heritage, the various incarnation's of TMPG's software have tended to lean toward an interface that doesn't require the user to have a lot of in-depth video related expertise. TMPGEnc XPress 4 continues that tradition, making it relatively easy for the average person to start using it with little or no training.
