Hi, but be patience: I'm a CAT
I use myffmpeg to help me suggest the just commandline.
My source is a xdcamhd422 .MXF file and using myffmpeg I need to generate a .MP4 4:2:0 at the same resolution and framerate.
This commandline, compiled directly from my paw works:
Code:ffmpeg.exe -y -i input.avi -vf scale=interl=1 -c:v libx264 -profile:v main -level:v 3 -g 33 -bf 2 -crf 20 -flags +ildct+ilme -top 1 -pix_fmt yuv420p -an -aspect 16:9 output.MP4
but the commandline suggest from myffmpeg is, for example, is this:
ffmpeg -i "V:\TeatroRavenna\ESP\teatroravennaOK.avi" -map 0:0 -an -c:v libx264 -crf 22 -r 25 -s 1920x1080 -aspect 1920:1080 -pix_fmt yuv420p -level 40 -weightp 1 -partitions partb8x8+partp4x4+partp8x8+parti8x8 -b-pyramid 2 -weightb 1 -8x8dct 0 -fast-pskip 1 -direct-pred 1 -rc-lookahead 10 -dct faan -coder ac -trellis 2 -me_method hex -subq 2 -me_range 16 -bf 3 -b_strategy 1 -refs 1 -flags +loop+ildct -sws_flags lanczos -sc_threshold 40 -keyint_min 25 -g 250 -qmin 3 -qmax 51 -qdiff 4 -threads 8 -metadata creation_time=now -sn -profile main -vf scale=interl=1 -pix_fmt yuv420p -level 41 -8x8dct 1 -trellis 1 -threads 12 -x264-params subme=7,chroma_qp_offset=-2,lookahead_threads=2,keyint=33 -qmin 0 -qmax 69 -qdiff 4 -rc-lookahead 33 -keyint_min 3 -flags +ildct+ilme -top 1 -g 33 -bf 2 -y "V:\TeatroRavenna\ESP\teatroravennaOK.mp4"
My problem is this: the presence of the -s 1920x1080 affects -vf scale=interl=1 so the risult is that the -vf scale=interl=1 don't act and the video image have a chroma ghost. All is ok when the the commandline don't include the -s 1920x1080 but using myffmpeg I cannot erase the -s 1920x1080 because at all times it always comes back (from myffmpeg) during encoding. I can only insert an "extra commandline arguments" from the -sn point and forward. I wonder if there is a way to keep the -s 1920x1080 and let act the -vf scale=interl=1 being that I cannot the -s 1920x1080 so I'm forced to add something in the extra commandline. What can I add in the extracoomandline space so that the -vf scale=interl=1 acts, if this is possibile? Thanks
