Thank you very much for your video, it was useful and interesting. I do have a question though, I am not clear on the difference between shutter speeds and shutter angles. Are those the same thing ? If not, can you select your shutter angle on a DSLR? Thanks.
Shutter speed and Shutter angle are just two different ways of describing controlling the shutter for video. Since film cameras used rotary shutters, they referred to shutter angles instead of shutter speeds like photography. I just wanted to show where the term "180 degree rule" came from, which is basically doubling your frame rate and using that number as your shutter speed (24 fps would be 1/48 shutter speed, and round that to 1/50 for DSLR). Does that make sense?
If you see actual film played back, shot at 24p/48th, you will see that the motion cadence and motion blur is NOT the same as a digital camera's 24p/48th or 50th footage. Even with all the other film look things being equal (e.g. color grading, shallow depth of field, highlight roll off etc), the motion is simply not the same. In fact, different digital cameras have different motion cadence that makes some of them more video-y than others. This is where we must take into account digital cameras with global shutter (or near global shutter), AND the imperfection of mechanical film cameras, AND what type of device we are viewing the footage at (e.g. LCD vs CRT vs projection, etc -- all behaving differently in terms of motion). Regarding the first item, Blackmagic has 3 camera models with soft global shutter, while Digital Bolex's CCD true global shutter sensor comes the closest than ANY digital camera to that of film! The Bolex truly feels like film! And regarding the second item, for us that we don't own a Digital Bolex, I think we need to use a faster shutter speed than 1/48th to achieve the non-perfect analog type of shutter and exposure fade-outs between shutter rotations found in film cameras. Everyone and their mother suggests 1/48th, but it might be that the reality to get closer to film look, might be 1/60th for 24p in all other digital cameras. What makes film so organic, is its analog imperfections. Same with vinyl and audio, and why it made such a comeback. Because people don't like the predictability of perfection. It takes them out of the dream and immersion.
The "magic" in film cinema cameras is in my opinion the rotary shutter, hence the shutter angle, not found in DSLR's or digital cinema cams. I cannot go out and buy a dslr with a rotary shutter. Also the next magical thing is the film itself. Film captures light in a logarithmic fashion with True RGB values across the exposure vs digital's linear way of capturing light with their Bayer image sensor which robs you of True RGB values of each frame. The most modern of mirrorless cameras have "pixel shift" in order to obtain true RGB values, but you have to have a tripod and not move the camera, so really only good for landscape photography and not for video.
Hi, I chose the shutter speed of 1/120 to go along with the 60 fps that I was using with my gopro hero 9 on my motorcycle. I was surprised to see that the video produced was washed out to the point that some things weer totally unrecognizeable. Can you shed some light on what may have gone wrong with that ride. I had previously left the shutter on automatic, but was looking to see if I could improve on the quality.
You need an ND filter to block out the right amount of light so that your exposure will be correct. This video on ND filters should help you better understand it: th-cam.com/video/5Eb94P4cJ70/w-d-xo.html
Camber, thanks for your reponse and the information provided. I watched your vid on ND filters and it's making a lot more sense. Going to order some today. Thanks again .
On digital cameras you have shutter speed, but it used to be called shutter angle because there was an actual spinning disc that had different angles cut out of it depending on the look of the film they wanted.
Basically you want your shutter speed to be double your frame rate for normal looking video. So if you are shooting at 24 fps, then you want a 1/50 shutter speed. 60 fps will use a 1/125 shutter speed. And 120 fps will use a 1/250 shutter speed to look natural.
How is it possible that 180° is the max shutter for recording? At 24fps It takes 1/48 of a second to get the frame in place. But they playedback at 72fps by tripling the original amount of frames and now it takes 1/144 of a second to get the frame in place. So at 24fps 180°/3 = 60° would be enough to get your frame in place and leaves 300° for exposure.
Speeding up the playback in post doesn’t change how the original was filmed. The film that you are playing back has already been exposed properly regardless of playback speed.
Everything on shutter speed is super clear right? 😂 Post your questions below!

Yes, thank you for the clarification.
Au rayon mangas, 👍🏽👍🏽
Nice channel, I accidentally came across your channel and I really like your tutorials. They are to the point and extremely helpful; thank you!
Thanks Genevie Vince ! I’m glad to hear it’s helping. 😀👍🏽

@@380stroker Great point! Wish DSLRs and mirrorless cameras had shutter angle options like the digital cine cameras.
GREAT explanation! Thanks!
You're welcome, Anthony! 👍🏼

No problem, Terry 👍🏾 Glad to help!
0:41 exposed to light ..and motion!
👍
What you mean by shutter angles?

please explain more i didn't get

thank you I now understand
You're welcome! 👍🏽
THANK YOU... SUB'D. See you around.
Thanks so much, A Giscombe ! 👍🏽
