Rack focus: The Cinematic mode uses computational techniques to simulate the effect traditionally achieved by physically moving a camera's focus from one subject to another. This creates a dynamic visual effect, drawing the viewer's attention selectively throughout the shot.
Computational background blurring: The iPhone analyzes the depth of the scene in real-time, isolating the subject and blurring the background. The intensity and quality of the blur closely resemble the shallow depth of field associated with professional cameras, resulting in a cinematic look.
Portrait Lighting effects: Cinematic mode incorporates Portrait Lighting effects, which were previously limited to still photography. These lighting styles help enhance the mood and visual appeal of videos, further elevating their cinematic quality.
Real-time depth segmentation: The iPhone's advanced machine learning algorithms enable it to accurately and quickly discern between the subject and the background. This real-time processing allows for sharp focus and seamless focus transitions.
Focus shifting during recording: Unlike traditional rack focus, which requires manual adjustment of the camera during filming, the Cinematic mode does it automatically. The focus transitions happen smoothly, creating a polished cinematic look similar to professional films.
Editing control: Users have post-editing control over focus choices and the amount of background blur, allowing them to refine the Cinematic effect and adjust it according to their creative preferences.
The combination of real-time depth estimation, computational blurring, Portrait Lighting effects, and automatic focus shifting creates a cinematic look that captures the essence of professional filmmaking techniques and brings them within reach of everyone with an iPhone capable of Cinematic mode.
