Tall dark object in forest of original video, gone when he does a follow-up video

Pale Horse Survival and Tactical posted a video a few days ago that had some signs of Bigfoot in it as well as a dark shape in the background of his video. He went back and did a follow-up to his video and the black shape is no longer there. He also walked out there for a size comparison. Here is the original and his follow-up video with time noted: (Dark object at 30:40) (6:48 is where he checks for the dark object, 12:55 is a possible print, and 25:34 is another possible print)
