[ffmpeg] interlace=lowpass=0 problem

[marcorocchini]

Hi c**s

I have a source 50P (input50P.avi) 720x576 that need to be resize to 1920x1080 and also interlaced

I have try to use

ffmpeg.exe -i input50P.avi -vf scale=w=1920:h=1080:in_range=tv:out_range=tv,unsharp=luma_msize_x=3:luma_msize_y=3:luma_amount=0.8,colormatrix=bt601:bt709,interlace=lowpass=0:scan=tff -sws_flags lanczos+accurate_rnd -an -pix_fmt yuv422p -f rawvideo - | ffmbc074.exe -threads 12 -y -f rawvideo -pix_fmt yuv422p -s 1920x1080 -r 25 -i - -i tempAudio_PAIR1_ForFFmbc.wav -i tempAudio_PAIR2_ForFFmbc.wav -tff -target xdcamhd422 -an "%DestFolder%/%~n1_reg8a_%panState%_UpScaleSDtoHD_xPDWF800_HD_.mxf" -acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 1:0:0:0:1:0 -acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 1:0:1:0:2:0 -acodec pcm_s24le -ar 48000 %Eventuale_dicituraFFMBC_Pair2%

but seems that the option

interlace=lowpass=0:scan=tff

does not affect the image "definition" never in the case of use of

interlace=lowpass=1:scan=tff

however I need to set

 interlace=lowpass=0:scan=tff

but the details of image are alwais low using interlace=lowpass=0can=tff or interlace=lowpass=1can=tff

why?

Of course details are "low". You're upscaling SD video. That's not going to increase detail.
