- File used was CLIP07.MPG ("Animal Handling"), taken from http://www.interniche.org/video_download.htm
- Used the following command to convert the file: ffmpeg -i CLIP07.MPG -vcodec mpeg2video -qscale 1 -qmin 1 -intra -ar 48000 CLIP07.mxf
- Note: FITS tools don't recognize the MXF format and only generate a small amount of generic file metadata as a result.
