Hi Vignan,
I am making some tests in DVCPRO50 now. The commands I am using are next
ones:
#----------------------------------------------------------------------------------
$comand="ffmpeg -y -threads 8 -i ".$input_file.".mxf -pix_fmt yuv422p
-aspect 16:9 -vf \"scale=720:576:interl=1,fieldorder=tff\" -sws_flags
lanczos -vcodec dvvideo -an ".$output_file.".dv";
#----------------------------------------------------------------------------------
$comand="ffmpeg -y -threads 8 -i ".$input_file.".mxf -pix_fmt yuv422p
-aspect 16:9 -vf \"scale=720:576:interl=1,fieldorder=tff\" -vcodec dvvideo
-an ".$output_file.".dv";
#----------------------------------------------------------------------------------
$comand="ffmpeg -y -threads 8 -i ".$input_file.".mxf -pix_fmt yuv422p
-aspect 16:9 -vf \"scale=720:576:interl=1\" -sws_flags lanczos -vcodec
dvvideo -an ".$output_file.".dv";
#----------------------------------------------------------------------------------
$comand="ffmpeg -y -threads 8 -i ".$input_file.".mxf -pix_fmt yuv422p
-aspect 16:9 -vf \"scale=720:576:interl=1\" -vcodec dvvideo -an
".$output_file.".dv";
#----------------------------------------------------------------------------------
$comand="ffmpeg -y -threads 8 -i ".$input_file.".mxf -pix_fmt yuv422p
-aspect 16:9 -vf \"scale=720:576:interl=1:unsharp=7:7:2.5\" -vcodec dvvideo
-an ".$output_file.".dv";
Please, tell me any advance in your tests. I am looking for the best
procedure to convert from 1080i to DVCPRO50 (50i)... but by now, in the
'downscaling' process I get some quality problems...
Thanks
Iban
