Cinematic Mode (n.) A video recording mode introduced on iPhone 13 that shoots footage with a shallow depth of field and automatic rack focus — the camera detects subjects and shifts focus between them as the scene changes, mimicking the look of a focus pull on a professional film set.
What Makes It Different from Portrait Mode
Portrait Mode applies background blur to still photos. Cinematic Mode does the same for video — but it goes further. It saves depth data alongside every frame of footage, which means focus decisions can be changed after you’ve already finished shooting. You can tap a different subject in the Photos app or Final Cut Pro and the focus shifts to them retroactively throughout the clip. It’s an editorial tool as much as a capture mode.
The rack focus effect — where focus transitions smoothly from one subject to another — is handled by machine learning that watches the scene for eye contact, detects when a new subject enters the frame, and decides whether to pull focus toward them. It’s surprisingly good at anticipating where attention should go. It’s also wrong often enough that you’ll want to review and correct focus decisions manually on anything important.
The Limits
Cinematic Mode shoots at 4K 24fps or 30fps (see Frame Rate) in Dolby Vision HDR. The quality is genuinely impressive for a phone. But the depth effect is computational — it’s estimated, not optically measured — which means edges aren’t always clean. Hair against a complex background is the classic failure point: fine strands can blur incorrectly, creating a halo that breaks the illusion.
The mode works best with clear subject separation. Give the camera contrast to work with — your subject against a receding background, with physical distance between them — and the effect holds up well. Two people standing close together against a matching background will confuse the depth estimation.
Samsung, Google, and other manufacturers have similar modes under names like Cinematic Video or Video Bokeh. The approach is the same; execution varies.
