My point is that taking times of youtube is inaccurate. How can he be completely right when all different times have been put up here.
Look at all the widely varying times on here
For most races the upload is so dodgy you cannot come close to getting an accurate reading. This one is no exception - the runners are miles away from the camera as they reach the bell. The speed they are going errors are going to creep in
ukathleticscoach, you still don't get it. What times vary? Guesses aren't analysis. Everyone who actually analyzed the video came up with the same numbers.
You don't understand the basics about the powerful tool at your finigertips - your computer or the files and methods you employ with it.
Video uploads aren't 'dodgy' at all. Anything you upload to a youtube server is an EXACT replica of what you created on your own computer. When a broadcast company creates an MP4 file the computer software that they use takes millions of bits of information and creates an incredibly precise product, laid down 29.7 frames per second. It isn't celluloid film or Super 8 or anything like that. It is an exact reproduction of what was filmed.
If, when you observe a video off of youtube, and have a crappy internet connection, or a computer with poor memory, or are overloading your computer with a bunch of different processes, the video may appear to freeze. That has nothing to do with the precision of the MP4 or youtube's technology voids, it has everything to do with the antiquity of YOUR personal computer. Living in 1999 in the 2011 age sucks, ukathleticscoach. Either get a better internet connection or get a new computer, but quit blaming the technology, and me, for a fault that isn't there.
If you have a crappy internet connection then simply download the video to your desktop. It will still be an exact copy of the one that was put on youtube. You won't be able to view if if it's not.

This has been proven false many times, and by many different methods, yet you still keep repeating it, as if repeating a falsehood will make it true.
