Main Page > Documentation > Media type preservation plans > MPEG-1 > MPEG-4 to MXF using FFmpeg
- 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.
