To clear up what a lot of people are calling a continuity error:

-The text at the start of Part 1 says that the video was recovered from a laptop found abandoned in a hotel room.
-->This is just referring to Part 1's footage.
-->The footage from Parts 2-5 were recovered from the camera found abandoned out in the field, as per the end of Part 5.

===>Actual possible continuity error next post.

Now, there is a possible continuity error in Part 2, where Jay switches out the SD card in the camera. Assuming he actually did, we shouldn't have the footage from that first SD card.
--This could be handwaved by saying that Jay didn't /actually/ switch out the SD card, that that was an illusion from the Operator.
