Through it all, we continued to support our community, moving most programming online and creating an Emergency Filmmaker Support Fund for our Fellows. But even in the midst of continued uncertainty, we remain fiercely committed to our work: championing creative independence in visual storytelling and supporting a community that embodies diversity, innovation and uniqueness of vision. If you are in a position to support our efforts, please make a donation. Your impact will double, dollar-for-dollar, with the generosity of our long-standing Arts Circle Member Susan Murdy.
The following piece originally ran in Special thanks to blogger Eric Escobar. The longer answer: the entire history of filmmaking technology is a series of hacks, workarounds and duct-taped temporary-fixes that were codified, edified and institutionalized into the concrete of daily practice. Filmmaking is one big last-minute hack, designed to get through the impossibility of a shot list in the fading light of the day.
The current explosion in distribution platforms internet, phones, VR googles means that the bedrock standard of 24 frames per second is under attack. The race towards new standards, in both frame rate and resolution, means a whole new era in experimentation and innovation. Truth is, cameras are a terrible metaphor for understanding how people see things. The human optic nerve is not a machine. Our retina is nothing like film or a digital sensor.
Human vision is a cognitive process. Motion in film is an optical illusion, a hack of the eye and the brain. Our ability to detect motion is the end result of complex sensory processing in the eye and certain regions in the brain. Early animators and filmmakers discovered how to create the perception of motion through trial and error, initially pegging the trick somewhere between 12 and 16 frames per second. Fall below that threshold and your brain perceives a series of discrete images displayed one after the other.
Go above it, and boom motion pictures. Movies and films are almost exclusively projected at 24 frames per second. Television does not have an internationally accepted frame rate.
Think about is the cost and size of your shoot. The more you have to edit and have storage for, the more difficult it is to wrap the project, so plan well ahead about the look you want to achieve and how feasible it is to complete in post.
Cameras are becoming more and more capable of filming at faster and faster frames per second speeds but at the expense of resolution though the technology keeps improving. Slow-motion effects are created by recording hundreds of frames per second and then playing them back at a slower rate.
An example would be a bullet shattering a light bulb. It may only take a fraction of a second but if the camera records the light bulb a thousand times per second and then plays back at 24 FPS, the movie onscreen will take almost 40 times as long.
Are you going for a slow-motion effect or a cinematic look? This will determine what frame rate you want to record at. Important to keep in mind is when you shoot video at 24 FPS you need to avoid quick pans and tilts because they may cause an image to stutter.
At 12 FPS or lower, your brain begins to differentiate the individual frames and they no longer seem seamless. Once you get up to 18 FPS, your brain can process the frames as fluid animation. In case you are wondering if frame rate is the same as shutter speed when shooting video on your DSLR, the answer is: no, it is not the same! This implies the shutter never closes!
Hi John, there is a slight typo on your website under the One other interesting add could be that 24 to It's hard to argue against that point. It's become as much a part of the artistic process as using a shallow depth of field. In the end, I think of the circumstances of how 24fps came about simply as a happy accident.
It's possible that, had it not have happened, some artistic cinematographer would have come along and done it anyway and audiences still would have loved it. An Avatar sequel will probably still look gorgeous at fps and the creative freedom to use a different technique to tell a story is wonderful.
If it suits a project, experimentation can produce wonderful results a great example is Saving Private Ryan using 90 and 45 degree shutter angles. The fact is that 24fps does suit film and it always will. Graphic by Shutterstock. Tags: Technology.
