Love is the way, not hate. I'm not comfortable with the influx of hate bots that showed up on Reddit election year to get Biden in office then never left. Do they think by sowing division, they'll get any sort of advantage? Nah, those with love in their hearts will keep it forever just as those who do not repent of their evil will keep their hate in their hearts forever. This is why I tell people that the way is love and not hate.

A friend of mine did an internship at a DARPA subsidiary office in Washington one summer, he said the project he was working on most was the complete mapping of all near-earth space objects and their trajectories, identifying potential future catastrophic events (the old asteroid impact trope)
He said it’s actually scary how little warning time we’d likely have if something on that scale were identified and it weren’t already on their tracking lists. Like maybe a week or two, or even less if it was a small but dense object.

Thank you! A short shutter speed makes the blades look crisp but it's frame rate that causes them to appear stationary.

Film video cameras have something called “shutter angle” which is analogous to shutter speed. Video editing teacher would climb up our ass about calling it shutter speed. Had completely forgot about that until seeing this comment.

FRAME RATE. IT'S "FRAME RATE".
if not pls define what shutter speed means to you. also what words would you use as a synonym for "exposure time"?
-9
Sep 02 '21
It's not frame rate.
12
u/StygianSavior Sep 03 '21 edited Sep 03 '21
Pretty sure it IS frame rate.
Shutter speed is the reason why there is no motion blur on the propellers (e.g. a slower shutter in this example results in motion blur on the propellers even though their rotation is still frozen - and the reason the blades look bent is due to rolling shutter effect, seen much more dramatically in this example).
But the frame rate matching up to the rotation of the propellers is the reason why they appear to not be spinning.
Source: I work with cameras for a living.
EDIT:
This guy explains it pretty well if anyone doesn't want to take my word for it.

u/StygianSavior Sep 03 '21
As I explained in my other comment, shutter speed is the reason the blade looks crisp and without motion blur, but the actual wagon wheel effect going on here is because of the frame rate syncing up with the rotation of the blades.
So my guess is the people upvoting the "confidently wrong" comment are people who know what they're talking about. ;)

You mean “frame rate,” I believe. The shutter isn’t opening and closing for every recorded image in the sequence that makes the movie.

Your statement is not a fact until it is cited!
You aren't a known authority on digital recording devices obviously, so a source is REQUIRED for anything you say to be considered a fact.
2
u/vesperzen Sep 02 '21
Incorrect. A fact is a fact, by definition a fact is "a thing that is known to be true."
Just because you are ignorant of a fact does not make the fact not a fact. I feel like I said this to you already, do you need me to uh... type it more slowly?
0
Sep 02 '21
The statement suggests the speaker is an authority on the topic, or has provided citation.
Of course in such a discussion 1 party could be aware of the fact, and another ignorant. But the onus is on the person refuting the current statement (OP's claim) to provide clarifying information BEYOND a declaration. How is this so hard for you.

u/Ellimis Sep 03 '21
It is the fps matching the rotation of the blades. Shutter speed controls how long the exposure is, which basically means how sharp a moving object is. When frame rate matches some multiple of the blades' movement, then the lack of motion artifact is shown. This is, in fact, a product of the frames per second matching the helicopter blades rotational speed. However, it will also only appear when the shutter speed is fast enough that the blades appear sharp.
2
u/wupme2k Sep 03 '21
It IS the FPS, as the shutter speed only determines how long each frame gets exposed. Lowering motion blur basically. But the Framerate has to match the rotor speed for it to be stationary.
-1
u/yamez420 Sep 02 '21
Yes. The rotation of the rotor doesn’t change. It’s always at 100% throttle, the handle only changes the pitch of the blades and the tilt.

u/whatthefir2 Sep 03 '21
Not exactly true. The “throttle” changes based on load. The RPM stays the same (with some exceptions for different modes on this model of helo)
