At end of the video I spelt the following wrong:
-movflags +faststart
Video filters discussed
gradfun=3.5:16 //.51-64:1.2 //8-32
nlmeans
ffplay -vf eq=brightness=0.06:saturation=2 movie.mkv
scale=3840:-1
unsharp=lx=13:ly=13:la=1.5
eq=brightness=0:saturation=1
CMDs:
ffplay -vf "filter1,filter2,filter3" input.mkv
ffmpeg -i input.mkv -vf "filter1,filter2,filter3" output.mkv
i.e. say my input is called movie.mkv and I want scale applied
ffplay -vf "scale=3840:-1" movie.mkv
ffmpeg -i movie.mkv -vf "scale=3840:-1" -movflags +faststart output.mkv
If ur audio is contained within ur movie to begin with remember to add -c:a copy before the output so you don't re-encode it. Otherwise just combine with ur container if u need to via ffmpeg -i input.mkv -i audio.wav -c copy output.mkv
Problems?
watch your spaces in the filename, if u have spaces put the name in "" i.e. "my video".mkv
to carry over all ur streams add a -map 0
ffplay -fs to go fullscreen
