Shutter Speed for Video EXPLAINED: How Frame Rates & Shutter Speed Work Together

August 26, 2019


– Hey guys. My name is Matt Johnson and
today I’m gonna be explaining shutter speed for video to
you as quickly as possible. What is shutter speed? Well, to understand what shutter speed is, first we need to talk about what is video. Video is actually just a
series of still images, also known as frames. And these frames are all put together and played back very quickly, so to your eyes they look like motion. In the case of this video, my camera is recording
at 24 frames per second. So, 24 still images per
second are being recorded and played back to you and
it looks like I’m moving. Now that we know that
video is just still images played back together, we can
talk about shutter speed. Two words, you notice: shutter and speed. Digital video cameras use something called an electronic shutter
that opens and closes to let light onto each
frame of your video. The shutter speed is how long that electronic shutter is open and each of those 24 frames
are being exposed to light before the camera moves
on to the next frame. In your camera, your shutter speed is measured by fractions of a second, 1/25th of a second, 1/30th of
a second, 1/50th of a second. The lower your shutter speed,
the brighter things will look because you are letting
more light into each frame. You’re probably thinking:
okay, that’s great Matt, I want things to be bright in my videos, so I’ll keep my shutter
speed low, awesome. Well, hold on. There is one other thing that
you need to keep in mind. The lower that you set your shutter speed, not only will things get brighter, but you will also introduce more motion blur into
each frame of your video because the electronic shutter
is being held open longer. If your shutter speed is
set to 1/25 of a second for a 24 frames per second video, then you’re gonna see a lot of motion blur when things move in your video. Alternatively, if your shutter
speed is set much higher, to 1/200th of a second, your image is gonna have
basically no motion blur and be much darker. Keeping all that in mind, the general guidelines
that most filmmakers follow is to keep their shutter speed
at double their frame rate which results in a nice mix
of motion blur and sharpness. So, if you were shooting
at 24 frames per second, then I recommend setting your shutter speed to 1/50th of a second. Matt, isn’t 24 times two 48? Shouldn’t I be selecting
1/48th of a second? Well, unfortunately, most
DSLRs and mirrorless cameras only let you select 1/50th
of a second, not 1/48th, but I wouldn’t worry about
this, it is close enough. Two more things and then we’re done. First, when I am shooting
at higher frame rates, such as 60 frames per second, I try to shoot with my shutter
speed at 1/125th of a second, which is roughly double
60 frames per second, but because there is so little motion blur at this high of a shutter speed, your video is not gonna look any different if you shoot at an even
higher shutter speed. When I’m filming outdoors at
60 frames per second or higher in the bright Texas sun, 1/125th shutter speed may still result in too bright of a video, so I’ll turn up my shutter
speed to 1/500th or 1/1000th or higher, whatever I need to set it to so my video is properly exposed. What about lower frame rates, like 24 or 30 frames per second, Matt? How do I keep my video
from being overexposed while still keeping my shutter speed at double my frame rate? Well, in that case, I would recommend investing
in a good variable ND filter. I have a review of a
variable ND filter adapter that I’ve made that I’ll
link to up in the corner and down in the description, as well as some variable ND filters that I recommend also linked
down in the description. Very last thing about shutter speed, and this is a rule that
you’re gonna wanna follow unless you really want
to mess up your footage. Never lower your shutter speed
lower than your frame rate. If you’re shooting at
24 frames per second, don’t drop your shutter speed
below 1/25th of a second to 1/20th or 1/10th, etc. If you do this, you’re essentially going
to break your footage and introduce all kinds
of weird motion blur that as far as I know isn’t really fixable without re-shooting. And that’s shutter speed. Please let me know down in the comments what you think about this no fluff, camera basics as quickly
as possible type of video. I also have another video that
I made all about frame rate, so if you wanna check that out, I’ll link it to it up in the corner and down in the description. I am planning on making more
videos like this in the future so I would appreciate it
if you want to subscribe. Thanks so much for watching
and have a great day.

  1. What do you think about camera basics videos with no fluff like this one? I tried to make it as short as possible. 😊

  2. isnt 1/1000 or 1/3200 to much to the point you couldnt see the image on the LCD screen outside on a sunny day?

  3. Hi matt. Thank you for keeping your stream fresh beside your new coming little Johnson.😁
    I have a question about frame rates. Do you record everything in 60p for the entire wedding shoot or just shoot the preps and highlight stuff in 60p for the intro video clip and shoot the lenghth video in 24p? Because if you put a 60p footage in a 24p timeline, th editing software will drop some frames and it will look choppy. You didnt mention it in your frame rate video. I ll be glad to hear your workflow. Thanks

  4. Hi Matt thanks for one more wonderful video . however I have a question what is the lowest safe shutter for low light at 120fps that I can go ..can I go as low as 1/100

  5. Matt thanks for the video. So Matt, if I shoot 120 frames, I can crank up my shutter also up to 4000th when I slow mo this to 24 frames?

  6. Hi Matt, I Live In The Caribean , Wedding Is My Thing to,If Have A Simple Asus Core i7 2016,shooting 1080p , im on a Budget, I want To Choose between the Panasonic DVX200 or Sony FS5, wich one can you recommend me?

  7. Hey Matt. I just want to thank you for all your lessons here, on youtube. I had no experience in wedding filmmaking, but right around march, a friend of mine asked me if I could shoot is wedding. I, a little anxiously said yes. So i started watching your videos to absorb the maximum amount of information that i could. The day came, and i shot the wedding. Then, it came the editing part. Although flawed as it is, the couple loved it and they said that I surpassed their expectations. I'm so happy right now, but, if it wasn't for your tutorials and explanations of everything, i wouldn't achieve this result. So, thank you so very much!
    Cheers from Portugal. 😉

  8. I liked this… I was thinking I knew all this already, but I wanted to see your way of explaining it. But yeah, I will admit I never thought about faster shutter speed than a certain threshold "not making a difference", and therefore being able to act as a pseudo-ND filter for higher frame rates. Okay, I did learn something. Very useful video, and I love videos with no fluff. I don't care about the length as long as you keep giving new info presented smartly.

  9. what shutter speed is best for shooting someone outside daytime, running fast, to avoid motion blur? (on a Sony A7r)

  10. Great video brother! Even when I think I know everything in this whole camera settings world, it’s great to hear some new insight! #Mattwisdom

  11. Before I start this video, I d like to state that I just subscribed. Every time I have a problem with Premier Pro I look for answers on youtube and one of your videos pop up with EXACTLY what I am looking for! I've watched so many videos and learned so much, at this point I felt guilty for not already being subscribed 😂 Thanks for the super content! you're a lifesaver!

  12. Thank you so much for this! So easy to understand and very helpful! Just subscribed! Will be watching more of your wedding tutorial videos!

  13. This video is absurd–sorry for being rude–because you're completely disregarding ISO and the f-stop setting.
    And yes, maybe one has to be careful and always set your ISO to the native ISO for that particular camera, but you can most likely change it a bit without causing a huge problem, if needed.
    But you're only talking about the relationship between frame rate and shutter speed, saying if you're shooting at 24 then the image will be too dark if your shutter is set faster than 1/50th. But what about the f- stop? How can you disregard the f-stop setting? That's the other way to control the amount of light coming in. This is just really half-baked and misleading.

  14. i have a device that can only capture 24,30,60,120 fps. shooting in a PAL country, is it OK to use shoot using 30 and 60fps and using shutter speeds that are multiples of 1/50 (1/100, 1/200)?
    My worry is flicker

  15. wooooooow couldnt bbe any clearer🙆🏼‍♂️🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼👏🏼👏🏼, thanks a lot Matt

  16. Awesome video !
    Im a new subcriber.
    Im learning photography and making video too. Your videos help me a lot.
    Thank you.

  17. I think one really practical issue emerges which led me on this youtube train. Not really found out what to do yet.

    It's the following. Many youtubers will shoot indoors and have limited flexibility in their lighting. In general, too little light.

    Pretty much every camera would allow shooting in 30 and 60 fps.

    Some might go with 60 fps even when they don't ever plan on slowing it down or uploading in 60 fps, just because they think it will allow for more information and better looking video after editing.

    Something that isn't as clear is how lighting factors in. The ISO will be higher at 60 fps all other things kept the same, right? Doesn't that mean that we would have sharper and less noisy video if we record in lower fps in badly lit indoors?

  18. from 2:50. could also try lowering the ISO to reduce exposure before relying on an ND filter

  19. I'm hoping you can answer this question for me. I'm using a Sony a7iii and a6500, when I set them up to full auto, my videos are set to match my SS to my frame rate, and not double my SS. I noticed i get a little bit less quality and more rolling shutter when moving too fast due to the slower SS, but my video overall seem to look very smooth. back in manual mode, when double my SS, to match my frame rate, it seem very hard to keep a nice flow of motion without any jitter, specially when panning, unless panning really slow. is it a Sony thing? or do I have to shoot slightly below the 90degree rule in my case to introduce a bit more blur?? and why does it by default set to match the SS with Frame rate if there are better ways???

  20. Hey Matt, thank god for your video! NO ONE ON YOUTUBE EXPLAINED THIS! 24 frames W/ 1/50 Shutter. it cleaned my ghosting effect I was getting with 1/60. littery made A HUGE DIFFRENCE

  21. Thanks pal, appreciate your help. I'm filming my mates wedding today so I'm just getting ready. I'm probably feeling more nervous then the groom lol.

  22. Great! I had no idea about the meaning of shutter speed for video. I was just using that "double" rule and when it was to bright I only would increase the shutter speed. But now I know a little bit more. Thanks man!
