i am trying to recode a video from 4096 to 3840 which i did succesfully with this line:
ffmpeg -i C:\Alien.mkv -vf scale=3840:2160 -c:v libx265 -crf 18 -acodec copy D:\Alien1.mkv -hide_banner
But the result video seems jumpy, like there is a pause between frames and it happens only when the scene has movement. The input and output framerate is the same (23976). Dont know what to do.
