Extended Preview of Luc Courchesne Ftg. - Enhanced, Recut, Missing Audio Replaced

Very rare (mostly) continuous view on WTC1 south side before 2nd plane impact. Messed-up interlacing repaired as good as possible. Doubled frame rate. Upscaled to 1920x1440. Distorted display aspect ratio of 3:2 corrected to 4:3. Denoised footage. Removed repetitive portion at 05:02 in the original preview video file. 7:22 - 7:55 -- Restored original audio which was removed here and replaced by the previous 23 seconds, either by Courchesne or by Nimia, probably to delete a loud conversation of Courchesne and another gentlemen in Canadian French in order to make it newscast suitable. Source for the audio restoration was another, shorter Nimia preview version, also found by YouTuber “911AnalysisVideo“ ( ).
