there is something wrong with the video on 0:13. something is cut out. maybe someone wants again Elon to share it on twitter and then say its fake stuff by Elon
Judging from the positions of the other cars, the two merged clips are almost certainly _not_ from two separate passes of the same stretch of road.
During the time missing from between the two clips the Tesla moves close to two full periods of the white stripes to its right.
The number of missing frames corresponds quite accurately to twelve frames in the first clip (where the speed can be assumed to be constant).
The running clock burned into the video is a bit strange, the fastest running digits wrap around to 00 after 29.
So they are hardly centi-seconds. They are also not incrementing by one, which they would have if they were counting the frames (i.e. 30 frames per second). But they nevertheless seem to be counting frames, since there are 30 frames for each advance of the second least significant pair of digits (which seem to be counting the seconds).
So the missing time is about 12 frames / 30 frames/second = 0.4 second.
So the video lacks a section corresponding to two full segments of the white stripes to the Tesla's right corresponding to 12 frames (probably 0.4 s), while the in-video clock advances as if no frames are missing.
This could maybe be explained by the recording camera being unable to record while copying data from one buffer to another (e.g. memory to SD-card).
So to me it seems less likely that the video has been tampered with and more likely that the video-recording software has some issues.
Maybe the video-recording is simply done with Tesla software, which is frequently deemed ripe for improving?
PS. Edited my speculation about the in-video frame-counter.
