[FFmpeg-user] ff* command lines that work

[hydra3333 at gmail.com]

Well, I'm a dumb user and google gave me LOTS and LOTS of commandlines that work - simply filter the google results by the "date in the last year" to be sure you get the latest syntax.  Lots.

You appear to continually avoid "what is it you wish to do with a specific example video that you have" type questions and just pose generalities, looking like a complete troll, which is why people are unhappy with your questioning approach.

I occasionally have a problem working out a commandline to use a specific video filter here and there, but googling and playing with it usually resolves the issue.

Here's an example of commandline I sometimes use (the numbers are calculated in a script and substituted into the commandline on the fly), so go for your life.

"C:\SOFTWARE\ffmpeg\0-homebuilt-x64\ffmpeg.exe" -v verbose -nostats -init_hw_device opencl=ocl:0.0 -filter_hw_device ocl -i "D:\TEMP\SCRATCH\example.mp4" -map_metadata -1 -vsync 0 -sws_flags lanczos+accurate_rnd+full_chroma_int+full_chroma_inp -filter_complex "[0:v]yadif=0:0:0,hwupload,unsharp_opencl=lx=3:ly=3:la=0.5:cx=3:cy=3:ca=0.5,hwdownload,format=pix_fmts=yuv420p" -strict experimental -c:v h264_nvenc -pix_fmt nv12 -preset slow -bf 2 -g 50 -refs 3 -rc:v vbr_hq -rc-lookahead:v 32 -cq 22 -qmin 16 -qmax 25 -coder 1 -movflags +faststart+write_colr -profile:v high -level 5.1 -af loudnorm=I=-16:TP=0.0:LRA=11:measured_I=-22.79:measured_LRA=15.70:measured_TP=-0.34:measured_thresh=-34.06:offset=0.40:linear=true:print_format=summary -c:a libfdk_aac -cutoff 18000 -ab 384k -ar 48000 -strict experimental -movflags +faststart+write_colr -y "T:\TEMP\example2.mp4"

Of course, I understand that.

That's not correct. A command line that has worked, worked. I don't need general templates. I just want command lines that have worked. I will figure out why they are specific to specific cases.
