Again a great video with lots of information and beautiful presentation. Though I am not sure but if a camera records at 24fps then I think the rotary shutter should rotate at 24rps instead of 24rpm.
Small correction: Around 2:20 you mention the default framerate is 24 frames per second, so the shutter rolls at 24 rpm. However, RPM is revolutions per minute, so a factor of 60 slower. When recording at 24 fps the shutter is making 24 rpS so 24*60=1440rpm. Edit: Just after posting this comment I noticed the pinned comment mentioning the same issue. Oh well.
That was great. Thanks for the explanation. I find it difficult to simply memorize things, but now that I understand what the angle actually represents, I suspect I'll never have trouble with this concept again. I've never seen anyone defining what angle was involved.
first of all thank you kindly for the video, because your explanation is really beautiful and easy to grasp. now that you made me understand the concept i would like to however fix the equation that you gave which i'm afraid is incorrect. if: SS ≡ ET is a shutter speed or equivalently exposure time measured in seconds per frame (spf), SA is a shutter angle measured in degrees (°), FR is a framerate measured in frames per second (fps), FI := 1/FR is a frame interval measured in seconds per frame (spf), then the formula you gave should read SS ≡ ET = 1/FR * (SA / 360°) or equivalently SS ≡ ET = FI * (SA / 360°). this way for FR = 24fps and SA = 180°, since then FI = (1/24)spf, we will get SS ≡ ET = (1/24)spf * (180° / 360°) = (1/48)spf as you said.
Surely it should be (Framerate x 360) / Shutter angle (usually 180), right? Your math would half the frame rate at 180 degrees, but you essentially just want to double it. I'm fairly sure I'm right on this but feel free to school me if I'm wrong. Thanks for the video, great way to explain the concept! TL:DR: Best shutter speed = Double the frame rate.
Thank you, Alexander! I've been embarrassed by my slowness in getting my head around the innerworkings of shutter angle, and though I really like the presentation in this video, that equation threw whatever confidence I'd gained up to that point. I appreciate your correction!
Great visual explanation for the rotary shutter. I'm pretty sure the correct math formula should be: Equiv. Shutter speed = (360/Shutter angle) x framerate tough wich would makes (360/180) x24 = 48 (put a 1 over 48 of course and there's the 1/48 value for the shutter).
Great video, and easy to understand, thanks But I think you made a mistake in the formula that you put on the screen, at the beginning you said that at 180 degree shutter angle the shutter speed is 48, and I agree. So the formula would be: "Shutter Speed = Frame Rate * 360/Shutter Angle" If we use the formula on screen would be: "Shutter Speed = 24*180/360 = 12" but "24*360/180 = 48". Thanks again for your information, I just bough a BMCC and I had no idea what Shutter Angle was, and you just made it clear to me
You did the math wrong....according to your equation...if my frame rate is 24fps...shutter angle is 180...then the equivalent shutter speed comes out 12..... how is this correct then??? it should have been 48 according to your video
your videos are easy to understand and make complex camera stuff easy. I've recently been trying to make sense of the micro four thirds and four thirds in comparison to dslr. any chance you can make a video explaining the difference and how they work please. Cheers.
Interesting video, I've been researching this subject for a while, because a friend of mine gave me challenge, I have a Sony FS7 which as you probably know has an awesome time-lapse mode, the challenge I've been given is to play around with the Shutter Angle to get smooth water in a coastal setting, I've tried various combinations and none have been a massive success, what setting would you recommend to achieve this. Angle, Speed and ND Setting?
You're a definitive resource ZY. Thank you for the time you put into your videos. What about slowing down motion on a 24p timeline? Can I change my shutter speed to allow for smooth slow mo? 45 and 90-degree shutter angles make for less blur in motion for film, so would I do that to then slow down the footage in post or go the other way and run the math for a shutter angle at 280 or so?
You lost me from 2:42 and on. I don't quite get what you said about the 180 degree shutter angle =/ But omg that illuminati confirmed is so unexpected and I'm laughing my ass off hahaha. Love your presentation style!
I'm sick of 45 and 90-degree shutter angles used for action scenes. Always makes the action look choppy, almost like stop motion. Blurs are far more appealing and naturalistic.
Wrong on two counts. RPM should be RPS as shutters speeds are measured over the duration of a second, not a minute. Your formula should be Frame Rate X 360 / Shutter Angle.

yeah
I was going to say
+bazdesh Oh yes! Good catch! My mistake! Yup it's 24 rounds per second, not per minute.
+ZY Productions Pinning this :)
I was also going to say...
The Math formula is wrong.. it should have been "equiv shutter speed = framerate x 360 / shutter angle
thank you
Your Right👍🏼, it was wrong when I did it his way.
Small correction: Around 2:20 you mention the default framerate is 24 frames per second, so the shutter rolls at 24 rpm. However, RPM is revolutions per minute, so a factor of 60 slower. When recording at 24 fps the shutter is making 24 rpS so 24*60=1440rpm.

now that you made me understand the concept i would like to however fix the equation that you gave which i'm afraid is incorrect.
if:
SS ≡ ET is a shutter speed or equivalently exposure time measured in seconds per frame (spf),
SA is a shutter angle measured in degrees (°),
FR is a framerate measured in frames per second (fps),
FI := 1/FR is a frame interval measured in seconds per frame (spf),
then the formula you gave should read
SS ≡ ET = 1/FR * (SA / 360°)
or equivalently
SS ≡ ET = FI * (SA / 360°).
this way for FR = 24fps and SA = 180°, since then FI = (1/24)spf, we will get
SS ≡ ET = (1/24)spf * (180° / 360°) = (1/48)spf
as you said.
Despite the discrepancy in the RPM mentioned in the comments, this was an awesome video, thank you so much!
VERY well presented! The best visual representation of shutter angle I've seen so far! Liked AND subscribed!

I really heartfelt thanks you for giving such opportunities to improve my photography. Hope I'll get more and more lessons form your channel.
Simple, short and demonstrated. My favorite kind of tutorial! =))
Great video, and easy to understand, thanks

woah! you're very good at explaining, keep up the good work!
Your videos are really good.
You did the math wrong....according to your equation...if my frame rate is 24fps...shutter angle is 180...then the equivalent shutter speed comes out 12..... how is this correct then??? it should have been 48 according to your video
the math is wrong for sure
that was right on! nice analogy it was easy to grasp
You have a very visually appealing intro to your video, and very informative video! :)
Which one is best best shutter speed
your videos are easy to understand and make complex camera stuff easy. I've recently been trying to make sense of the micro four thirds and four thirds in comparison to dslr. any chance you can make a video explaining the difference and how they work please.
Cheers.
Very helpful, thanks for the quality explanation
Great explanation
Well done and thank you. Great explanation!
Great very informative vid with good humor!
Great video! I love your humour!
Freakin perfect explanation. THANK YOU!
Clear as day. Thanks!
Nice job!
Awesome video,thanks!
This is mad brilliant
Great,
Thanks Man for your Sharing.
even though i already knew most of the info going in, i enjoyed your presentation of the content! illuminati had me loling hard haha
How do this work in digital video?
Interesting video, I've been researching this subject for a while, because a friend of mine gave me challenge, I have a Sony FS7 which as you probably know has an awesome time-lapse mode, the challenge I've been given is to play around with the Shutter Angle to get smooth water in a coastal setting, I've tried various combinations and none have been a massive success, what setting would you recommend to achieve this.

Really good explanation, but it would be great if you meantioned that the shutter is no rotating slice anymore its electronic shutter today
You're a definitive resource ZY. Thank you for the time you put into your videos. What about slowing down motion on a 24p timeline?

I get the concept but what happens when your shutter angle isnt 180° everybody says shutter speed has to be double the frame rate but why? 🤔
Becoz at this shutter angle it will give you a very comfortable and natural motion blur
Couldn't get why do i need to know that and what or how to use it for shooting videos?
Great video. Would've been better if you had illustrated the different effects achieved by changing the shutter angle as well.
FPS x 360/180(172.8) (24 x 360 = 8640/180 = 48) (24 x 360 = 8640/172.8 = 50)
This is great.
Thank you!
u2417h it's a good monitor?:)
its great explanation
what is that spiny thing?
It's a spinny thing! :)
Correction i Think; Here is an exsample. Divide 360 by 45 to get 8, then multiply that by your frame rate of 24 to arrive at a shutter speed of 1/192
Good information i got..
yeh, but artistically what's the difference. when does it make sense to adjust the shutter angly, artistically?
You lost me from 2:42 and on. I don't quite get what you said about the 180 degree shutter angle =/
But omg that illuminati confirmed is so unexpected and I'm laughing my ass off hahaha. Love your presentation style!
Ok so you didn’t explain what it is or how it’s used. Why would you use shutter angle over shutter speed?
Loooot of information thank You!!!
2:22 *1440 rpm
Concise without obligatory B-roll
Feels like Algebra again. I Hated algebra. Im confused. but I understand if you get me!
How knowing this been useful ?
and how i can know my angle to use the equation ?
Very nice 👍🏻🇬🇧
Thankyou!
2:20 24 RPM ????? 😣 - - - 1,440 RPM !
Yes, RPS! hehe. Thank you.
I'm sick of 45 and 90-degree shutter angles used for action scenes. Always makes the action look choppy, almost like stop motion. Blurs are far more appealing and naturalistic.
It will be 24 RPS ( 24 rotation per second )
michał botor's comment is correct
now my brain hurts
😱
rps not rpm... however, nice video :)
Wrong on two counts. RPM should be RPS as shutters speeds are measured over the duration of a second, not a minute. Your formula should be Frame Rate X 360 / Shutter Angle.
But why this way?
@2.20 ... At 24 rpm I'll get 0.4 fps.. at 360° shutter angle.....Ryt???
OMG if u spam press L to skip through the video the loading icon becomes a fidget spinner :O
Its not rotating at 24 RPM. its 24 rev per seconds. FPS
no entendi una garcha
Wrong.
Speed = (frame rate * 360) / angle
i like his voice lol...
Fps not rpm
rps* (if thats even a thing) rotations of the shutter per second
rpm is what you use to measure the rotation of any round object like wheels and shit
so pretty much its the same
rpm is rotations per minute and in this case its every second
so pretty much you are dumb ... RPMinute ,Frames Per Second ...different ...he ment 24 FPS ... that will actually make 1440 RPM .... ;)
did i ever tell you i love you?
so...yeah i do
You got the math wrong there. Shutter speed= (Frame rate x 360)/Shutter angle
it´s the same, it can be done either way e.e
