But the first thing you should do after downloading the video is check in MediaInfo that you’ve downloaded the HDR version. Obviously, this decision makes sense for novice users who might download the Dolby Vision-encoded video, play it on their SDR screen, and recoil in horror at the dingy and washed-out appearance. Check Keep Originals to copy Dolby Vision-encoded videos to your computer. And you need to select Keep Originals in the Photos app ( Figure 3, below) to transfer Dolby Vision rather than SDR H.264.įigure 3. After two hours of searching, I learned that you have to either use iTunes on Windows or Photos on the Mac or iCloud photos. I checked the video in MediaInfo and saw that not only was it not HDR, but it also wasn’t even HEVC. (Or at least users like me.) Apple’s market cap proves that they’re right and I’m wrong, but it’s frustrating to spend two hours trying to figure out why the video that’s clearly Dolby Vision on your iPhone copies down to your computer as SDR video.įirst, I tried connecting my iPhone to my Windows computer with a cable and dragging the video file from iPhone to my hard drive. My own beef with Apple is that when they attempt to make things simple for novice users, they often make them incomprehensible for users who know what they are doing. Dirty Secret Number 1: Apple Makes it Hard to Export HDR Once you shoot your video, you may find that transferring it from phone to computer is more challenging than you might imagine. If you’re shooting for an SDR production, I recommend choosing SDR for simplicity. Which format should you use? If you’re shooting video to include in an HDR production, to upload to YouTube, or for display on your own HDR TV, you should go HDR. Choosing HDR/Dolby Vision capture on your iPhone If you don’t select the HDR option you shoot in SDR.įigure 2. ![]() In your iPhone, you choose whether to shoot in HDR format in the Camera settings as shown in Figure 2 (below). The iPhone stores in Dolby Vision profile 4 as defined above. You don’t need to know what HLG or BT 2020 is or does, but as you’ll see, you’ll want to keep these as consistent as possible in Adobe Premiere Pro through project setup and output.įigure 1. As explained in the video, the iPhone uses Dolby Vision Profile 4 which is a 10-bit 4:2:0 HEVC-encoded video, which uses the HLG transfer characteristic and BT 2020 color primaries. Second, HDR has multiple characteristics that you’re probably not familiar with, some of which you can see in Figure 1 (below), an explainer video from this Dolby page. So displaying HDR on SDR displays is not optimal. SDR displays also use a different transfer function than HDR, which controls how the color and brightness data in each pixel is displayed on the screen. First, HDR may look pretty dingy on strandard dynamic ranger (SDR) displays because they can display only a portion of the color and brightness that make up the file. There are a couple of things about HDR you should keep in mind when shooting and playing it back. Apple added an HDR to its Super Retina displays on the iPhone X and added Dolby Vision capture and playback on the iPhone 12. As you know, HDR uses an expanded range of brightness and expanded color space to produce a more vivid image. About Dolby Visionĭolby Vision is Dolby’s high dynamic range (HDR) specification that’s included in many premium 4K and larger HDR TV sets. Let’s start with what Dolby Vision is and why you should care. If that journey is of interest, come along. ![]() But included in that thimble is how to publish HDR videos from your iPhone to YouTube, with an intermediate step through Adobe Premiere Pro. I’ll be straight with you: What I know about producing HDR wouldn’t fill a thimble. ![]()
