  • Ticket #9872 – Description

    initial v1  
    99Following commands, esp. out-webp-scale.png output demonstrates the issue:
    1010
    11 ```
     11{{{
    1212ffmpeg -filter_complex "color=white:200x200[b];movie=x.png,[b]overlay" -y out-png.png
    1313
    … …  
    1717
    1818ffmpeg -filter_complex "color=white:200x200[b];movie=x.webp,scale=200:200,[b]overlay" -y out-webp-scale.png
    19 ```
     19}}}
    2020
    2121I tried all possible scale filter flags, and also format changing (before and after scale) but no luck to achieve the same result. I am able to un-premultipy the problematic one with `unpremultiply` filter but I would like to avoid it.
