East penthouse is already gone. It remains unknown, if the local collapse sequence starting at ~5:20:46pm with east penthouse falling through, was either missed by the camera person or was removed from the video subsequently. 8:27 - Total collapse starts 3 seconds later after the cut, actually at 5:20:52pm (+/- 1 sec), with the downward movement of remaining ~3/2 of core dragging down the rest of roof structures, closely followed by the four perimeter walls. Videographer: Unknown/WNBC-TV or NBC News. View from north. POV = West Broadway near Leonard Street. NIST version with the cleanest audio so far, despite the missing audiotrack on the right channel. Enhanced video quality taken from DVD Video, created from the mini-DV tape by NIST for FOIA release. Like many full-length videos released by NIST, the entire video tape is lacking of the audiotrack on the right channel. Link to the non-enhanced version: https://youtu.be/Sn4JinG1cKI Video has been deinterlaced and losslessly recompressed. The FPS has been doubled, the video frame has been upscaled anaphormically corrected from 3:2 to 4:3 DAR (720 x 480 px) to 4:3 DAR (1440 x 1080 px). Contrast, brightness and color saturation has been adjusted in order to enhance visibility. Audio from remaining left channel has been copied on to the blank right channel and the audio gain has been increased. Stereo-widening effect has been applied on the right channel. Video and audio has been recompressed again by lossless video/audio encoder before the upload on YouTube. DAR = Display Aspect Ratio.
