I want to crop the video at some position and move the part next to the part that wasn't cropped. (See image, it explains better)

enter image description here

This should do it:

ffmpeg -i input.mp4 \
-filter_complex "[0:v] crop=iw/3:ih:0:0,pad=iw:2*ih [left]; \
 [0:v] crop=iw/3:ih:(iw/3)+1:0 [middle]; \
 [0:v] crop=iw/3:ih:(2*iw/3)+1:0 [right]; \
 [left][middle] overlay=0:main_h/2,pad=iw:(3*ih/2) [out1]; \
 [out1][right] overlay=0:(2*main_h/3) [fout] " \
  -c:v libx264 -an -map "[fout]" trisected-vertical-overlay.mp4

I haven't supplied any specific video or audio encoding parameters. This just shows the overlay filter to use. You'll have to encode and map the audio, as needed.

Using crop and vstack:

ffmpeg -i input -filter_complex \
"[0:v]crop=iw/3:ih:0:0[left]; \
 [0:v]crop=iw/3[center]; \
 [0:v]crop=iw/3:ih:ow*2:0[right]; \
 [left][center][right]vstack=inputs=3[v]" \
-map "[v]" -map 0:a -c:a copy output 
  • vstack is faster than pad + overlay.

  • If your ffmpeg is too old for the vstack filter then just download a recent build.
