• How to add blurred border on top and bottom based on the video

  5 avril 2023, par Noob69

  I am trying to modify a video to 1080x1920 scale and I want to add to the borders on top and bottom, a blurred version of the video based on the pixel on the edge.

  


  import subprocess

input_file = "my_video1.mp4"
output_file = "my_video_processed1.mp4"

command = f'ffmpeg -i {input_file} -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2,eq=saturation=2.0:gamma=1.2:contrast=1.2,unsharp=lx=5:ly=5:la=0.5:cx=5:cy=5:ca=0.5" -c:v libx264 -preset slow -crf 18 -c:a copy {output_file}'
subprocess.call(command, shell=True)



  


  I tried
mode = replicate, however it is not working for the latest version of ffmpeg from Windows builds by BtbN.
