Open FB video (for example walking on the water), then:

1. open DevTools (F12), then Network tab, watch for calling two GET URLs one-by-one, each with .mp4 inside: first is video without audio, second is just audio (both you can Open in New Tab) - so do Copy As cURL for both, and execute them as below (assuming 1.mp4 and 1.mp3 for both video and audio correspondently):

   IMPORTANT: it's required to remove 2 HTML params from the end of URLs: &bytestart=XXX&byteend=YYY!

   curl --output 1.mp4 https://scontent.xx.fbcdn.net/o1/v/t2/f2/m69/AQO...Kq9.mp4\?strext\=1\&_nc_cat\=108\&_nc_sid\=...&oe\=679C6293
   curl --output 1.mp3 https://scontent.xx.fbcdn.net/o1/v/t2/f2/m69/AQP...HqV.mp4\?strext\=1\&_nc_cat\=1\&_nc_sid\=&oe\=679C8E9F

✗ rg -in adsbygoogle * | more
✗ find . -type f -iname \*.html.bak -delete
