haiz.. video analysis
re-encoded video to mpeg1 @30 fps, so 1 frame is 0.033 second. but still need to correlate to video cam clock.
this is the last frame before ferrari appears. take note of the building pillar at the extreme left of video. that'll be our start distance marker. also, cam clock shows 9:20, while video time is 20.133 sec.
next frame at 20.167 sec. ferrari just enters the video, and appears to be in line with 2nd pillar from the left of the (kfc) building. but because the lens is fisheye, there is some distortion to the perspective captured (i.e. car should be behind 2nd pillar). hence, i can only estimate that the ferrari is somewhere in between the 2 pillars between frames 604 and 605 (again necessary to estimate distance/time). cam clock still shows 9:20.
next frame at 20.200 second. ferrari clearly in view. cam clock just turned 9:21.
moment ferrari touches cab. cab is just starting to shift right due to impact. take note of position of the taxi's bonnet in the 4th lane, that'll be the end marker. video time is 20.467 sec, only ~0.33 seconds from the beginning just before the ferrari enters the footage. but it's not real time.
at 21.200 sec, cam clock turns 9:22. so at least for this segment of footage, video time and cam clock pretty much runs in sync. (read above, cam clock at 9:21 was 20.200 sec). hence, the ferrari covered the distance from the 1st-2nd pillar of the (kfc) building to the 4th lane of junction in ~0.33 sec ± 0.1 sec. Still a large probability of error due to limitation of video recorded and software.
so how long was the distance?
ironically, the orange top cab was at the rough position where the ferrari hits. calculating using google map (crossing locations are off in google map due to construction works then) and perspective estimation, the distance covered in 0.33 seconds is around 25-30 metres.
which calculates out to, at slowest, (25/0.43 x 3.6) = 209 km/h
