You clearly ignored by post about video encoding/decoding, didn't you? You (and others of your ilk) don't want to know or understand how it is that your cherished "nose out" conspiracy video is actually just a video artifact introduced by multiple levels of video compression and decompression, do you?
Anyone watching (and more importantly) listening to that video with an unjaundiced ear would recognise that this bit of video is being replayed sometime well after the fact of the initial impact, either before WTC 2 came down or sometime mid-afternoon would be my guess. So it isn't "live" per se but is, rather, tape playback.
That said, you provide no evidence whatever that this video is the as-broadcast footage from FOX. In fact, you accuse them of altering "the historical record" because (assuming you've actually seen their aircheck and aren't pulling this assertion out of your back passage) their tape doesn't show what your cherished "nose out" YouTube video does, completely and conveniently ignoring my entire point about video artifacting created by multiple encode/decode passes as the video passes through various stages in the distribution chain from broadcaster to viewer.
In fact, this video equivalent to Gage's 'thermite' sample. The video signal has gone from FOX production tape room to their production control room to their broadcast master control to their broadcast antenna. The broadcast antenna (or the direct connection with the cable companies) is where FOX's control over the signal ends. In all likelihood, the FOX aircheck was the made in the production control room recording the production switcher output. This would be as clean an image and unsullied a signal as you're going get. Once the signal leaves master control, all bets are off.
From there, the signal quality is at the mercy of the cablers (whether Toronto, Rat Portage or where-have-you) and/or satellite companies, both of whom introduce additional compression/decompression (often multiple times in their own signal chain) which throws away progressively more information before the video and audio is delivered to the home user. In this case, the home user has recorded it, likely on VHS tape. VHS tape in the best of circumstances is about half of broadcast resolution. So still
more information lost.
Then our valiant video 'truther' digitised the low-resolution video on a consumer-grade video editing solution, throwing away yet
more data at that stage. Then he edits, outputs to a digital video file a la QuickTime or Windows Media of one flavour or another, uploads to YouTube (which compresses yet again).
Talk about a muddied chain of custody!
And you wonder why it is that the FOX original footage (if in fact you've actually seen it) doesn't show your cherished "nose out"? You don't seem to care to understand why it appeared to show it in the first place.
