Say I had 4 videos with the following names:

  • Main Video.mov
  • Top Left.mov
  • Top Right.mov
  • Top Mid.mov

and I wanted to have "Main Video" play with a picture in picture effect with boxes of videos playing in the top left, top right and top mid. Each box would have the video that is similarly named.

This command will do picture in picture for 2 videos, with one video in the lower right.

ffmpeg -i 2013-07-31\ 231548.MOV -vf "movie=2013-07-31\ 231722.MOV, scale=iw/5:ih/5 [small]; [in][small] overlay=main_w*0.77:main_h*0.77 [out]" -strict -2 output.mov

Can someone help me update this command to work with the 4 files I mentioned above?

Thanks
