Even more astounding is the fact that Bolt started from a speed of zero and then had to accelerate, which means that his top speed actually was faster. cities of Boston, New York City, and San Francisco.

That’s faster than the estimated average traffic speed for the U.S. Since many people are more familiar with automobiles and speed limits, it might be more useful to think of this in terms of kilometers per hour or miles per hour: 37.58 or 23.35, respectively. That means that Bolt’s speed during his world-record run was 10.44 meters per second. It is represented mathematically as speed = d/t (in which d is distance and t is time). Speed is the rate at which an object (or person) moves through time. For those of us more accustomed to sitting than sprinting, to translate this feat into terms of speed is to simply underscore the stunning nature of Bolt’s performance. In 2009 Jamaican sprinter Usain Bolt set the world record in the 100-meter sprint at 9.58 seconds.

You can do that with the free download, Handbrake.

In your case that would mean increasing the 24fps frame rate of the iPhone SE video to, say, 29.97.

Not exactly sure how to do that, but I think that Sound Track Pro or possibly the free down load, Audacity, could do it.Īnother thing I read from another poster on this forum, is that he was able to get his audio in sync by increasing the frame rate of the slower video/audio clip. If it is 44.1 KHz, then that could be the issue, in which case you might consider converting the audio sample rate to 48KHz with an audio editor app.

Open your iPhone SE video in Quicktime, and then select Window/Show Movie Inspector, and you can find out what sample rate the audio is. Your iPhone 6 audio is at 48KHz but your iPhone SE might be at 44.1 KHz, that would make the iPhone SE audio slightly slower relative to the iPhone 6. I would guess that the two audio tracks are recorded at different sample rates. This area is out of my range of expertise, but I'll give you my comments based on some cursory reading. I have read that audio sync is a common issue when you try to mix audio tracks recorded on two different devices.
