ffmpeg encoding with optical flow?

[marcorocchini]

Hi c**s ,

I have a 30P video source that I would like encode into a target output (mpeg2) 25i (interlaced output) if possible using ffmpeg.

Please can you tell me the commandline??

and can I do a render encondig using NVidia hardware capabilities? thanks

I have try:

ffmpeg.exe -threads auto -y -f concat -safe 0 -i concatList.txt -vf "scale=interl=1,minterpolate=fps=50:mi_mode=mci:mc_mode=aobmc:me_mode=bidir:vsbmc=1" -vcodec mpeg2video -g 0 -intra -q:v 0 -pix_fmt yuv422p -minrate 50000k -maxrate 50000k -b:v 50000k -af "pan=stereo|c0=c0|c1=c1" -c:a pcm_s16le -ar 48000 -aspect 16:9 out.MXF

because source is 30P and 4:2:0

my target is a 25i and 4:2:2, possibly mxf format container

so I wonder: is correct and necessary to use the

scale=interl=1

option?

and: this commandline output a 50P video, but I need to out in 25i: what modify I have to do this?

and... 1,5 fps speed encoding: is there a way to improove the encoding speed cat thanks?
