  • FFMPEG Replacing black color fragments with alpha channel transparency

    31 décembre 2017, par kostya572

    I have file.mov video. It has a lot of blank black color fragments that have different durations.

    I need to replace black color fragments that show up for more than 5 seconds with transparency. Is that possible to add some alpha channel for that purpose ?

    Comment to Mulvya’s answer :

    Amazing solution. With #2 section everything ok.

    With #1 section I created this code :

    output=$(ffprobe -f lavfi -i "movie=file.mov,blackdetect=d=3.5" -show_entries tags=lavfi.black_start,lavfi.black_end -of compact=p=0 -v 0|awk '!/^$/')
    
echo $output

    using awk '!/^$/' to remove empty lines.

    Here is the output I get :

    output

    tag:lavfi.black_start repeats with same value several times, not having right structure with closing tag:lavfi.black_end

    If I change blackdetect=d=3.5 to other value, for exaple d=10, it outputs the same result as d=3.5. How could I solve this issue having right tag:lavfi.black_start,tag:lavfi.black_end synthax with correct grepping d= value ?
