  • FFMPEG sepia filter

    28 juin 2018, par Alex Konetchy

    Can’t seem to figure out why my colorchannelmixer filter is not working with ffmpeg. It doesn’t appear to output any errors, but the ouput.mp4 video is just a 0 second long video with no thumbnail.

    Here’s the command I’m trying.

    ffmpeg -i video.mp4 -filter_complex \
    
"[0:v] colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131[f1];\
    
[f1] eq=1.0:0:1.3:2.4:1.0:1.0:1.0:1.0 [outv]" -map "[outv]" output.mp4

    And the output I receive.
