Frame rate doubled. Color saturation and levels have been adjusted. Frame has been re-centered by cropping the frame borders and resizing to 640x480 px by preserving the 4:3 aspect ratio before upscaling. Audio volume raised by 11 dB and audio has been slightly denoised. Audio delay of +64 ms has been corrected. No entry of tape found in the 2011-released NIST Video Tapes Database (file: "Copy of Video_List.mdb"). Information on record from the NIST WTCI Documents Database (file: "file: "tblDocumentMain.xlsx""): Document ID: WTCI-000223-I Document title: "Videotapes and Binder of Photographs of Fireproofing Taken on March 8, March 20, April 13, and July 17, 2001, Former Offices of Harris Beach on Floor 85 of WTC 2; Transmittal Letter" Reupload with improved features, after YouTube has destroyed my initial upload from Oct. 23, 2013 due to creating nasty video blocking artifacts when it did re-encoding of videos around 2016, apparently for tighter H.264 video compression.
