  • File used was from an unprocessed archival fonds
  • Used the following command to convert the file: ffmpeg -i file.mp4 -vcodec mpeg2video -qscale 1 -qmin 1 -intra -ar 48000 file.mxf
  • Note: FITS tools don't recognize the MXF format and only generate a small amount of generic file metadata as a result.
