Doesn't look like a Boa constrictor or Anaconda, or a Reticulated Python. Maybe some photoshop editing work.
I found a video that had additional footage of a snake, presumably the same one, being loaded into the back of a minivan.
The resolution was better and close enough to get an idea from the pattern. I wish I didn't lose it. Went back and gave up after fifteen minutes so it could be posted. Anyhow, it looked like a retic. I know that they are native to Indonesia and much of S.E.Asaia, but there's three possibilities.
1. Clickbait. Perhaps it was footage taken from Asia and not the Caribbean.
2. Perhaps the tictoc post credited got the wrong info.
3. It may have been an invasive, perhaps from an Asian import or pet shop.
Forth..... misidentification.
Anyway, it's big, but not a world record. Perhaps a record for the island. I used to have retics, so it's not a good "pet.". I would not be surprised if it was released after a nasty bite.
Unless it was seriously injured and partially paralyzed, a wild reticulated python would not let three or four guys feed it into the back of a van.
