CreateMpeg is a frontend to mpeg2enc.elf. You need mpeg2enc.elf in the same
  directory as CreateMpeg and the runelf program in your path.
  Also, gtlayout.library is used for the GUI.

  Source:       Enter the source file pattern here (as a printf-style string).
                The file externsion (.ppm, .yuv) will be added by the encoder.

                Example:
                You have the files pic0001.ppm, pic0002.ppm etc.
                Enter "pic%04ld".

                If the filenames have no leading zero (pic1.ppm, pic2.ppm...),
                type in "pic%ld".

  Target:       Target filename

  Format:       Input format. This can be "YUV split" (three seperate files per
                frame with extensions .Y, .U and .V), "YUV" (one file per frame)
                or "PPM".
                If set to PPM, Width and Height are taken from the file. Only P6
                files are valid.

  Frames:       Total number of frames

  1st frame:    First frame number

  Width:        Picture width. Should be a multiple of 16.

  Height:       Picture height. Should be a multiple of 16.

  Aspect ratio: Aspect ratio

  Framerate:    Frames per second

  Bit rate:     This detemines the quality as well as the size of the MPEG
                file.
                Higher values mean better quality at the expense of larger
                file size.
                Lower values mean lower quality and smaller file size.

  Start:        Start the encoding process

  Quit:         Quit program
