- File used was sample_1238959806.avi, taken from http://www.filefront.com/13539232/sample.avi/
- Used the following command to convert the file: ffmpeg -i sample_1238959806.avi -vcodec mpeg2video -qscale 1 -qmin 1 -intra -ar 48000 sample_1238959806.mxf
- Note: FITS tools don't recognize the MXF format and only generate a small amount of generic file metadata as a result. In addition, some of the elements that are considered significant properties are not extracted by FITS for the original file. Therefore some of the metadata in these tables are taken from the FFmpeg metadata that were generated during conversion. These are indicated by FFmpeg in brackets next to the value.
