[Hamza El farissi]

Hello Kieran,

Stream mapping:
  Stream #0:0 -> #0:0 (mpeg2video (native) -> dvvideo (native))
  Stream #0:1 -> #0:1 (pcm_s24le (native) -> pcm_s16le (native))
Press [q] to stop, [?] for help
Output #0, dv, to 'Sony21.mxf':

This is the command i used :

ffmpeg -i Sony.mxf -codec:v dvvideo -b:v 50000k -minrate 50000k -maxrate
50000k -top 0 -s 720x576 -pix_fmt yuv422p -target pal-dv50 -codec:a
pcm_s16le Sony21.mxf

and this is the mediainfo i get from the output file

i would like the format to be DV50, the commercial name to be DVCPRO50, Bit
rate to be 48.8 MB/s, Scan Order to be Bottom Field First

Thank you very much for your help
