  • FFMPEG image overlay zoompan leaving shadow

    21 octobre 2018, par Pier Giorgio Misley

    I have the code for adding many images overlay to a video. It works fine, but since every overlay a white shadow of the image is kept until the end of the video, like this :

    enter image description here
    As you can see, a white shadow of all images is kept in the center of the image.

    This is my code :

    -i "input.mp4" -i "1.png" -filter_complex "[1:v]format=yuva422p,scale=7290x4850,setsar=1/1,pad=1.5*iw:1.5*ih:(ow-iw)/2:(oh-ih)/2:color=black@0,zoompan=z='min(zoom+0.0010,1.5)':s=729x485:d=400:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)',fade=in:st=0:d=3:alpha=1,fade=out:st=13:d=3:alpha=1,setpts=PTS+22/TB[im1];[0][im1]overlay=(main_w-overlay_w)/2:(main_h - overlay_h)/2" -pix_fmt yuv420p -c:a copy "output.mp4"

    (in that code I add only one image, but there might be more)

    Why this white shadow is kept since the overlay to the end of the video ?

    Thanks
