For anyone else who is looking for an automated solution to convert their 6.7 screen recorded videos to Apple's required 6.5/5.5 dimensions,
here are some recent ffmpeg commands I wrote which helped me:

Note: The instructions below assume you're the on-screen recorder to capture a portrait-mode video 
on the iPhone 12 Pro Max ( using the native 888x1920 resolution )

// Convert to 6.5 ( 886x1920 requirement ) using a centered cutout ( by shaving 1 pixel off sides )
ffmpeg -i input_6.7.mov -vf crop=886:1920:1:1 -r 30 -crf 18 output_6.5.mov

// Convert to 5.5 ( 1080x1920 requirement ) using a centered cutout ( by subtracting 128px-height menu bar so we can keep aspect ratio )
