Resolution Explanation

• Resolution calculation process:
  1. First determine total pixel count based on selected resolution preset (e.g., 4K, 8K)
  2. Calculate final width and height based on selected ratio
     • Example: When selecting 8K (about 33.2M pixels) and 9:16 ratio
     • Results in 4320x7680 output resolution (4320x7680=33.2M pixels)
     • Ensures total pixel count matches preset value
