What is a 180 degree shutter?
The 180° Shutter Rule states that your shutter speed should be set to 1/frame rate x 2. So at a frame rate of 24 fps, the correct shutter speed is 1/48 sec. For 30 fps, a 180° shutter would be 1/60 sec. To achieve normal motion blur in your footage, you can use the closest shutter speed.
Does shutter angle matter?
The larger the opening, the longer the film will be exposed, and the longer moving objects will move during the exposure, introducing motion blur. “The shutter angle traditionally controls the amount of motion blur. The longer the film is exposed, the more motion blur the image will get.
How do you break a 180-degree rule?
Cutting to a shot across the imaginary line breaks the 180-degree rule, but moving the camera during an uninterrupted shot allows you to cross the line without disorienting the audience. You can use this technique to signal that there’s been an emotional shift in the scene.
What happens if the 180-degree rule is broken?
The 180-degree rule is broken, and your suspension of disbelief takes a knock. You can cover a reverse cut with a cutaway. If you catch it on set, you can choose to move the camera around the characters before the cut, or have the characters themselves move during the preceding shot.
When can you break the 180-degree rule?
One of the most basic continuity rules is the 180 Degree Rule. The 180 Degree Rule states that two characters in a scene should always have the same left/right relationship to each other. If you don’t follow the 180 Degree Rule, or break it intentionally, it disrupts the scene disorients the audience.
Should I use shutter angle or shutter speed?
The “shutter angle” is a useful way of describing the shutter speed relative to the frame rate. The larger the angle, the slower the shutter speed, all the way up to the limit of 360°, where the shutter speed could become as slow as the frame rate.
What shutter speed should I use for 120 fps?
A good rule of thumb to go by is to ensure that the denominator of your utilized shutter speed (ie: 1/48, 1/96, 1/44, etc) should be doubled what your frame rate is. So, if you’re shooting at 60fps, your shutter speed should be 1/120 and a 1/240 shutter speed for 120fps — so on and so forth.
