How to use FFmpeg for removing watermarks in the existing video? Is this possible with this library? Any help.

Try the delogo filter with a custom filter:

Hi, I tried by below code but failed.

FFMpeg::open('public/tiktok/7118695488282447131.mp4')
            ->export()
            ->inFormat(new \FFMpeg\Format\Video\X264)
            ->addFilter(['delogo=x=475:y=965:w=100:h=77'])
            ->toDisk('public')
            ->save('7118695488282447131_delogo.mp4');

Exception

How I can resolve it? Thanks.

add your filter like this. tested and works fine. ->addfilter('-vf', 'delogo=x=375:y=749:w=85:h=85')
