Does Dolby Vision video take up more storage than standard video?

Dolby Vision itself does not significantly increase file sizes compared to standard HDR video. The additional HDR metadata added to each Dolby Vision file is minimal. File size is primarily determined by resolution (1080p vs 4K) and frame rate (30fps vs 60fps), not the HDR standard.

Can I share Dolby Vision video with people who don't have Apple devices?

Yes, with some caveats. Dolby Vision files (.mov) can be shared via iMessage, AirDrop, and most cloud services. On devices that do not support Dolby Vision (older TVs, non-Apple devices), the video typically falls back to a standard SDR or HDR10 compatible version embedded within the same file. YouTube, Vimeo, and Netflix all support Dolby Vision.

What Is Dolby Vision HDR on iPhone?

Q: Which iPhones record Dolby Vision?

Dolby Vision video recording was introduced on iPhone 12 (all models) with iOS 14.1. All iPhone models from iPhone 12 onward record all standard video in Dolby Vision HDR by default. There is no toggle to disable it — every video you take on a modern iPhone is Dolby Vision.

Dolby Vision is a premium HDR (High Dynamic Range) video standard that dramatically expands the range of brightness and color that video can represent. All iPhones from iPhone 12 onward record every video in Dolby Vision by default, capturing up to 10-bit color with dynamic metadata that tells compatible displays exactly how to render every scene for maximum impact.

What HDR and Dolby Vision Mean

Standard dynamic range (SDR) video captures brightness levels roughly equivalent to a dim room — it clips highlights and crushes shadows. High Dynamic Range (HDR) video captures a much wider range from near-black to near-pure-white, preserving detail in both bright skies and dark shadows simultaneously.

Dolby Vision is the most advanced commercial HDR standard. Unlike HDR10 (which uses static metadata — one brightness target for the entire video), Dolby Vision uses dynamic metadata — brightness and color instructions that change scene-by-scene or even frame-by-frame, so each moment is optimized for the display it's being shown on. This produces more accurate, more vibrant results, especially on Dolby Vision-certified displays.

iPhone Dolby Vision Support

iPhone 12 series (2020): First iPhones to record Dolby Vision, at up to 4K 60fps.
iPhone 13 / 14 / 15 / 16: All models record all video in Dolby Vision at up to 4K 60fps (standard) or higher with ProRes on Pro models.
Display support: iPhone 12 and later display Dolby Vision content natively. The OLED displays on Pro models cover a wide P3 color gamut and reach peak brightness suitable for Dolby Vision rendering.

10-Bit Color Depth

Dolby Vision video records in 10-bit color, versus 8-bit for standard SDR video. 8-bit color can represent 16.7 million colors; 10-bit expands this to 1.07 billion colors. In practice, this means smoother gradients in skies and skin tones, and vastly reduced color banding — the visible stepped transitions that can appear in 8-bit sunset footage.

Sharing and Compatibility

Dolby Vision .mov files from iPhone are broadly compatible:

Apple devices: Full Dolby Vision rendering on iPhone 12+, iPad Pro, MacBook Pro (2021+), Apple TV 4K.
YouTube / Vimeo: Both platforms support Dolby Vision upload and streaming.
Older devices / TVs: Dolby Vision files contain an embedded backward-compatible SDR or HDR10 layer that plays automatically on non-Dolby Vision displays.
Windows: Requires Dolby Vision-compatible software player; standard Windows Media Player does not support Dolby Vision metadata.

Dolby Vision and Storage

The Dolby Vision metadata stream is small (a few kilobytes per second) and does not meaningfully increase file size compared to standard video at the same resolution and frame rate. Storage is driven primarily by resolution and codec choice. See the iPhone 4K video storage guide for detailed figures.
