example2
$ ffmpeg -i main.mp4 \
-i overlay.mp4 \
-filter_complex "[0:v] pad=iw*2:ih:0:0 [main]; [main][1:v] overlay=W/2:0 [ov]; [ov] scale=iw*0.7:ih*0.7" \
output.mp4
This command line concatenate "main.mp4" for left and "overlay.mp4" for right into output.mp4.
- [0:v] : first input(main.mp4)
- pad=iw*2:ih:0:0 : padding with "width=iw*2, height=ih, x=0, y=0". iw=input_width, ih=input_height
- [main] : output for padding filter
- [1:v] : second input(overlay.mp4)
- overlay=W/2:0 : overlay with "x=W/2, y=0". W=width of [main]
- [ov]: output for overlay filter
- scale=iw*0.7:ih*0.7 : scaling with "width=input_width*0.7, height=input_height*0.7"
