iPhone HDR Video: Should You Leave It On or Turn It Off?

Should you turn HDR video on or off? It depends where the clip goes

HDR isn't better or worse in the abstract. It's a different kind of file, and it only pays off when every step after the camera understands it. Match the setting to the last place the video will be watched:

The YouTube row is the cleanest case: according to YouTube's HDR upload guide, viewers on non-HDR devices see the video as standard dynamic range, converted automatically. Most other destinations are less predictable, which is why a single test post beats any rule of thumb.

iPhone HDR video is only an improvement when every step after the camera supports it. An HDR clip played on an HDR-capable Apple screen keeps its highlight detail; the same file opened in software that treats it as standard video looks flat and washed out. The deciding factor is the final viewing screen, not the recording.

How to turn off HDR video on iPhone

The switch lives in Settings, not in the Camera app. Apple's guide to adjusting HDR camera settings on iPhone gives the same path:

1. Open Settings.
2. Tap Camera.
3. Tap Record Video.
4. Turn off HDR Video.

Two things catch people out. First, the setting only affects new recordings; everything already in your library stays HDR. Second, HDR Video and photo HDR are separate: turning off HDR Video doesn't change how the iPhone takes still photos. If you switch HDR Video back on later, nothing else in Record Video changes, so your resolution and frame rate stay where you set them. For choosing those, the frame rate guide for YouTube covers when 24, 30, or 60 fps makes sense.

Why iPhone HDR video looks washed out or too bright elsewhere

Standard video is built for a brightness curve and color space that date back to HD television. iPhone HDR video uses something different on both counts. It's encoded with HLG (Hybrid Log-Gamma), a curve designed to hold far brighter highlights, in a wider color space, at 10 bits per channel. Ten bits gives 1,024 levels of brightness per color channel instead of the 256 in 8-bit video, which is why skies and window light keep their gradients instead of banding.

On top of that sits Dolby Vision metadata, which tells capable screens how to map the image to their brightness. Apple's developer documentation on HDR video with Dolby Vision describes it as Dolby Vision Profile 8.4, built to be backward compatible with HLG, so any HEVC decoder can still play the file.

Playing it isn't the same as showing it correctly, though. When an app ignores the HLG curve and the wider color space and treats the file as ordinary video, the image comes out flat, grey, and low in saturation: the classic washed-out look. When a player does show it as HDR on a phone that's also displaying normal app interface around it, the video can look much brighter than everything else on screen. Both are the same file, read two different ways.

iPhone HDR video is 10-bit HLG with Dolby Vision Profile 8.4 metadata, according to Apple's developer documentation. Ten-bit encoding stores 1,024 brightness levels per channel instead of 256. Software that reads the file as standard 8-bit video ignores the HLG curve and wide color space, which is what makes HDR clips look washed out.

How to convert an iPhone HDR video to SDR

Turning HDR off fixes future clips. For footage you've already shot, make an SDR copy instead of trying to grade the grey out by hand. Apple's guide to editing HDR video recorded on iPhone covers the built-in route:

• iMovie on iPhone or iPad: add the clip to a project, tap Share, tap Options, and turn HDR off. The export is standard dynamic range.
• iMovie on Mac: shares in SDR, so exporting from it converts the clip.
• Desktop editors: use the editor's HDR-to-SDR or color space conversion on the clip or timeline. A proper conversion maps the highlights down; dragging contrast and saturation sliders only approximates it.

Keep the original HDR file. If the clip later goes somewhere that supports HDR, the conversion can't be undone, but the original still has everything.

High Efficiency or Most Compatible: what it has to do with HDR

Settings > Camera > Formats offers two choices. High Efficiency records HEVC (H.265); Most Compatible records H.264, the older codec nearly everything can open. The catch is that iPhone HDR video is HEVC only, so choosing Most Compatible gives up HDR along with HEVC's smaller files.

If compatibility is the reason you're tempted to switch, there's a better fix: keep High Efficiency and turn off HDR Video. That removes the washed-out problem while keeping files small. Apple's notes on using HEVC media on Apple devices also point out that 1080p at 60 fps or lower is the most widely compatible HEVC on older devices, a useful default for clips you send to other people.

HDR video vs Apple Log: which one do you need?

They solve different problems. HDR Video is finished-looking footage, ready to post. Apple Log, available on iPhone 15 Pro and later, records a deliberately flat, grey image that keeps maximum highlight and shadow detail for color grading. You turn it on in Settings > Camera > Formats by enabling Apple ProRes and setting ProRes Encoding to Log, as described in Apple's guide to ProRes on iPhone.

Log only makes sense if you grade every clip in an editor such as Final Cut Pro or DaVinci Resolve. ProRes files are many times larger than HEVC, and ungraded Log footage looks worse than either SDR or HDR. For talking-head content, tutorials, and social clips, it's the wrong tool.

HDR for talking-head and scripted videos

Talking-head footage is where HDR's trade-off is easiest to see. Its strength is a bright window behind you or beside you: HDR keeps the window from blowing out while your face stays exposed. Its weakness is consistency. White walls, skin tones, and on-screen text shift the most when an HDR clip is converted or misread, and those are exactly what a viewer stares at. The talking-head video settings guide for iPhone covers lighting that makes HDR unnecessary in the first place.

If you read from a script while you film, Teleprompter-Scrolling Scripts, a free teleprompter app for iPhone, has its own HDR switch for each project in Camera mode. It records 10-bit HDR, with Dolby Vision on iPhones that support it, and it starts off, so a project headed for an editor stays SDR while one you post straight from Photos can use HDR. In our own shoots, that per-project split is the habit worth copying in any app: decide where the clip is going before you press record, not after.

Frequently Asked Questions

The short version

Keep iPhone HDR video on when your audience watches on Apple devices or YouTube, and turn it off when footage passes through an editor or goes to SDR screens. For clips already shot, export an SDR copy rather than correcting by eye, and keep High Efficiency on either way. For more on choosing a recording setup, see the comparison of free teleprompter apps.
