• FFMPEG add circular mask to videos, convert to black and white and concatenate

  3 mai 2018, par Yassine

  Hello everyone i’m a beginner and i would appreciate your help.

  I’m making a mobile application that generates custom video resumes based on the user’s videos taken from his phone, the user has to upload 5 different videos to the server from the mobile application, in the server side i want to :

  • Add a .png circular mask to each video.
  • Make each video black and white.

  • Concatenate the videos with other already existing title videos
    (e.g [userVideo1] [title1] [userVideo2] [title2]...) Visual Example

    [Edit : I would like more features]

  • Add background music
  • Add watermark logo in the middle
  • Remove silent footage from the beginning and from the end
  • Some input videos might be rotated, i want to rotate videos back to normal if they are rotated.

  So far i managed to add the circular mask, make the videos black and white and concatenate 3 videos including a premade title video, but the second user video has no sound in the output.

  This is the script i ended up with :

  ffmpeg -i uservid1.mov -i uservid2.mp4 -i mask.png -i title1.mp4  -preset 
  
  ultrafast -filter_complex "

  [s2][s1]overlay[vid1];  
  
  [2:v][1:v]scale2ref[s3][s4]; 
  
  [s4][s3]overlay[vid2];  
  
  [vid1]hue=s=0[v0]; 
  
  [vid2]hue=s=0[v1];
