[FFmpeg-user] Best way for converting HD 1080i to DVCPRO25 DV?

[Iban Garcia]

Hi,

I have materials in HD 1080i (50i), and I want to transcode them to
DVCPRO25 (576i). I am using next command, but I do not know if it is the
best:
*
*
*ffmpeg -y -threads 8 -i original_video.mxf -b:v 25000000 -s 720x576
-pix_fmt yuv411p -aspect 16:9 -an -r 25 output.dv*

Any suggestions to improve the quality? Do you usually useany kind of
filtering to downconverting from HD to SD?

Many Thanks

Iban
