You likely know about Wired article, where they discovered from the video metadata that it was edited and that it actually used two source clips. You also know about the missing minute from 11:58:58 to 12:00:00. Another redditor used a different exiftool command for more metadata. There you can find the lengths of the two source video from the PantryDurationValue field, giving values 15556150ms and 23760550ms, which become 4:19:16 and 6:36:00 and together they sum to 10:55:16. The actual video is 10:52:24, so 2 minutes and 52 second are missing.
Also conveniently, the footage starts at 7:40:00 PM (4:20:00 to midnight, 40:18:58 if counting the missing minute ) and ends at 6:40:00 AM. So if we go by the theory that the 4:19:16 section was from 8/9/2019 and 6:36:00 section was from 8/10/2019 (explains the aspect ratio change), there are actually 18 seconds missing from 8/9/2019 and 4 minutes of extra footage compared to the source clip.
I would appreciate somebody double-checking my math.
