Source VIdeo used for Measurements and Object Tracking

All object tracking measurements shown on this website are taken from the following source video.

Capable readers are encouraged to check and verify all results to their satisfaction.

Source video information

video sources:

Sauret viewpoint

Youtube version: http://www.youtube.com/watch?v=xGAofwkAOlo&feature=channel_page

The first 20 seconds are the original Sauret video.

Features:

1) The camera shakes about 9.5 seconds before collapse.
2) The antenna and the NW corner of the building begin to slowly move during or immediately after the camera shake.

achimspok Sauret version: starts some seconds prior to the shaking camera.

File specs:
97.730.578 bytes
Audio: Dolby AC3 48000Hz 6ch 224Kbps [AC-3]
Video: MPEG2 Video 720x480 (16:9) 29.97fps 9608Kbps [Video]
duration: 02:04,124

The unfolded video fields into frames gives 7440 frames at 59.94fps. Just a segment of it is used. Frame 2005 of the unfolded version is the first frame "000".

The architecture in that area doesn't allow for many possibilities and those possibilities would affect the results in a very small way since the most important relation is the appearance of the antenna in the projection plane of the north face. For this projection plane we get the pixel-height relation from the video. It wouldn't change at all. So the results should be very close if the Sauret camera is placed 1342m north and 662m east of the center of the north tower at 32m above ground. The north tower is 29° turned towards the east.

It is a packed rar. It includes numbered JPGs for every frame at 59.94fps and the numbering Achimspok used. The videos are 29,97fps! Therefore you always have the same frame twice. The Sauret included is the blown up "field 0" of the original interlaced frames.


Video synchronisation is performed relative to multiple physical events on the building at frame level.

NOTES:
......

OWE Sauret version: framerate is 29.97 (recombined fields). The set of points are over-determined because there's some uncertainty in matching. Hopefully this assists. An entire thread devoted to this may provide additional info:

http://the911forum.freeforums.org/sauret-data-synch-t239.html

and a comment on why OWE frame numbers are off by 10 from the beginning of the segment are the first couple of paragraphs of this post:

http://www.the911forum.freeforums.org/technical-notes-on-video-motion-analysis-t55-315.html#p7680

There is a difference of 195 frames between OWE's and achimspok's versions.

Achimspok Sauret video long version

which measures from the period before the camera shaking at 10 seconds before visible collapse.
