    Light Speed
In summary, the article explores whether the speed of light can be used to differentiate timelapse videos from real-time motion. It discusses the limitations of human perception and the physics of light, emphasizing that while timelapse videos compress time, the inherent differences in the depiction of motion and the effects of light can sometimes help viewers distinguish between the two. However, the effectiveness of this distinction varies depending on the context and content of the footage.

TL;DR Summary
In a Timelapse video of a person traveling at 10X the speed recorded you can observe increase in velocity WITHOUT incurring the relativistic effects of the apparent velocity, and this would be because a Timelapse speed up would , unlike going faster for real outside the Timelapse Speedup, Would change the speed of light demonstrated in the video
my question then is that can we ascertain some unknowns about the physical constants of our universe by using video altered speeds , to observe the universe through moving picture frames ? Is there a project benefit in doing more with this ?

Suppose we have a billion people standing in a single file line clustered together along the shoulder of a major highway , with clocks synched using a convention of choice , independently take a photo aimed at the highway at as close the same time t …

Next, we gather all the billion photos and keep them ordered in sequence , We run them through a slideshow and what we get to watch is as IF a single traveler is in motion navigating the highway while exceeding the speed of light, which is made possible by independent photographers whose snap did not depend on signals from the line of peers except the peers standing very closely next to them, but the idea here is because the photos were “independently” taken and would be impossible to be captured by one system alone …. I think there’s something to be valuable doing this for visual compare

Basically your question seems to be, can we get useful information from some data by first monkeying with the data so it is no longer representative of what actually happened? I don't see how.

No, what you will get is some number of adjacent photos that, when put together, show a snapshot of the traveler at one instant, and the rest of the photos showing no traveler at all.

Nobody is in motion there’s actually no travelers in this simultaneity experiment. It’s a billion photos as close to the clustered location atomic clock adjusting based on Einstein convention as the line of photographers moves more and more up the highway…. The motion is the result of running a Timelapse where each person’s photo is a single frame consecutively a tiny drop of distance further up the highway than the photo before it, yet the photos were taken by independent workers , so then say we get 60 frames per tenth of a second … animation apparent motion up the highest … Where everyone is part of the travel and no single photographer traveling … but it plays out like someone’s highway drive in a universe where speed of light is slowed down

Then I have no idea where you got this from:

How is this even possible? If there is no traveler, all of the photos will just be of an empty highway.

What atomic clock? There was no such thing in your scenario.

@ESponge2000 you need to either specify a consistent scenario that makes sense or this thread will be closed. There is no point in wasting people's time trying to guess what you mean from your vague and rambling statements.

It's in the traveler's pocket. Or non-travelers non-pocket. Or something.

OP, how is this different from Google Maps where you have multiple pictures of a highway? Maybe that will help you explain what the heck you are trying to say.

we have a billion independent observers standing in single file along the shoulder of a highway. Each one is interactive with the one in front and behind
The first one is in the back, the last one is in the front …. They each hold an atomic clock and a camera (maybe one smart device) to help them keep a simultaneity without having to wait for signals from the back .

they use Einstein convention to synchronize all their clocks .

After the billion photos are taken, they are compiled in order of bottom to top and end product, a slideshow where the view is of being in motion l on the highway but with no time elapsing on earth

So each one a picture of the highway and the clock, both in their field of view?

Supposing that is the case, what is this supposed to show? Nothing is actually moving. You could do the same thing by just compiling a bunch of photos taken at any time you like at the appropriate places on the highway with a clock set to show the appropriate time. What would it prove? Nothing except that you can make a slideshow that shows anything you like, whether it actually happened or not. So what?

Google maps does not capture all photos from a close time interval of precision and then stack them into a slideshow for animated video presentation

From having the photos in close sync with a time at the start of the line , and making it into an animated video of many still photos sped through , we can experience what a line of simultaneity looks like if one could observe it. It’s a trip up the x-axis of a space-time diagram

A) Why don't you take a regular movie and speed it up? Why this rigamarole of a billion photographers with atomic clocks?

B) What is this supposed to show, other than you can make special effects (well, one special effect) like they do in Hollywood?

No, you wouldn't, since it is impossible to observe a line of simultaneity.

Thread closed due to personal speculation.
 

FAQ: Can “speed of light” distinguish all Timelapse videos from real motion?

1. What is the speed of light and why is it significant in distinguishing timelapse videos from real motion?

The speed of light is approximately 299,792 kilometers per second (about 186,282 miles per second) in a vacuum. It is significant because it represents the maximum speed at which information and matter can travel through space. In the context of timelapse videos, which capture images at set intervals and play them back at normal speed, the speed of light helps define the limits of how quickly events can be recorded and perceived. If events occur faster than the speed of light can transmit information, they may not be accurately captured in real-time.

2. Can timelapse videos ever accurately represent real motion?

Timelapse videos can represent real motion but do so by manipulating the speed at which events are shown. They condense time by capturing frames at intervals much longer than the actual event duration. As a result, while they can illustrate processes that occur over extended periods (like plant growth or cloud movement), they cannot accurately depict fast-moving objects or phenomena that occur in fractions of a second, which may require high-speed cameras to capture true motion.

3. How does the frame rate of a video affect the perception of motion in timelapse videos?

The frame rate, or the number of frames captured per second, plays a crucial role in how motion is perceived. In timelapse videos, a lower frame rate means fewer images are captured over a longer duration, leading to a faster playback speed. This can create a surreal sense of motion that does not accurately reflect the timing or fluidity of real-life events. If the frame rate is too low, rapid movements may appear jerky or unnatural, further distinguishing timelapse from real-time motion.

4. Are there any limitations to using the speed of light as a criterion for distinguishing timelapse from real motion?

Yes, there are limitations. The speed of light is a fundamental constant, but it does not account for the complexities of motion and perception in video. For instance, while the speed of light can help determine whether an event is captured in real-time, it does not consider factors such as the observer's perception, the context of the motion, or the technology used to record and display the video. Therefore, while it is a useful criterion, it is not the sole factor in distinguishing timelapse from real motion.

5. Can advanced filming techniques blur the line between timelapse and real motion?

Yes, advanced filming techniques can create effects that blur the line between timelapse and real motion. Techniques such as high-speed photography, motion blur, and digital effects can alter the perception of motion in a way that makes it challenging to distinguish between real-time footage and manipulated sequences
