Recording of first clip starts at 8:49:06 a.m. according to NIST VideoList. Time uncertainty margin of each clip has been determined by NIST as 1 second. 0:13:11 - Impact explosion and jet-fuel fireball at the north face of WTC2 at approx. 9:02:54 a.m.. Smoke expulsions at the east and north faces of WTC1 on upper floors. TV signal (CBS Channel 2) is lost for about three seconds, then again at 0:13:51. 0:14:33 - Clip change. TV signal is apparently lost again. Beginning of long continuous and relatively static shot of Twin Towers burning until 1:01:56 (9:04:39 a.m. to 9:52:01 a.m., +/- 1 second according to NIST). Unfortunately, camera lens has been zoomed out bit too far during that shot. 1:01:55 - Last clip repeats the footage from 9:48:32 a.m. to 9:52:01 a.m.. Northeast view (elevated). 336 Broadway (near intersection of Worth Street and Broadway).

NTSC DV files deinterlaced (BFF order) and decompressed. Upper horizontal frame edge cropped for 4 pixels, resolution upscaled while keeping aspect ratio, sharpness, color saturation and contrast encreased. Chroma noise has been lowered by a HQ denoising filter. Audio stream has been resampled (32 kHz to 48 kHz by a 129 taps filter).
