I watched the whole video and this is my opinion on it. First of all, I am a strong supporter of 9/11 truth and I do not believe for a second that a
plane actually hit the pentagon, HOWEVER...I don't think the "helicopter" footage at the end was genuine footage. To me, it looks like CGI overlaid
on real helicopter footage. I watched it several times and it actually looks poorly faked to me. I'm no video analyst, but the explosion doesn't
look real, IMO.
Now, in regards to the officially released security cam footage, I think the anomalies could be from one of two things (or maybe both):
1) the slow frame rate of the cameras
or
2) doctored footage
The fade in of the object is clearly demonstrated in the video and I do not have enough knowledge of video editing to say why you can see a fade in.
It could possibly be smoothed so that it doesn't look like a choppy frame by frame slide show (X....X....X....X....X....X).
My question is, who's idea was it to edit the evidence to a heinous crime like this? Who care's if it looks nice on tv? It's suspicious at best.
