  • FFMPEG Downgrade Only If 4k Video and Keep Aspect Ratio

    30 août 2020, par Devin Dixon

    Is there a way to downgrade video resolutions if and only if they are above a certain resolution ?

    


    For example, right now I am doing to :

    


    ffmpeg -i 4k_VIdeo.MP4 -vf scale=1920:1080 -c:v libx264 -crf 35 1080-video-smaller.mp4


    


    But if the video is 720:600 or a smaller resolution, I don't want to expand to 1920, also if the video is not the aspect ratio of 1920:1080, I want to keep the same aspect ratio so it doesn't look distorted.

    


    Is there a way of doing this ?
