How do I move (rearrange) the orientation of a video? Using ffmpeg
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.
