Commands that I used manually with FFmpeg

#Get the grid info
ffprobe -loglevel trace "C:\Users\arsen\Downloads\23094872309478\20250926_175705.heic" 2>&1 | Select-String "grid_row"

#Process original to save as tiles
ffmpeg -i "C:\Users\arsen\Downloads\23094872309478\20250926_175705.heic" -map 0 "C:\Users\arsen\Downloads\23094872309478\tile_%d.png"

#Combining tiles together
ffmpeg -i "C:\Users\arsen\Downloads\23094872309478\tile_%d.png" -vf "tile=8x6" -frames:v 1 -update 1 "C:\Users\arsen\Downloads\23094872309478\20250926_175705_full.png"

#Removing... or at least trying to remove the black edges cuz tiles was extracted wrong I think
ffmpeg -i "C:\Users\arsen\Downloads\23094872309478\20250926_175705_full.png" -vf "crop=4032:3024" "C:\Users\arsen\Downloads\23094872309478\20250926_175705_cropped.png"

#Just rotates the image
ffmpeg -i "C:\Users\arsen\Downloads\23094872309478\20250926_175705_full.png" -vf "transpose=1,crop=3024:4032:0:0" "C:\Users\arsen\Downloads\23094872309478\20250926_175705_final.jpg"
