In case you hadn’t observed, Apple launched its Vision Pro spatial computing headset on February 2, 2024. It’s a daring transfer, signaling the tech large’s entry into the digital and augmented actuality market—with an equally daring price ticket of $3,500 USD per unit.
One of Vision Pro’s distinctive benefits is its place within the Apple product ecosystem, so you’ll be able to count on synergy with Apple’s Macs, iPhones and different merchandise. For occasion, you’ll be able to seize 3D video with an iPhone and look at it on a Vision Pro later. Knowing this potential, I’ve been capturing spatial movies over the vacations in 2023 and past, meaning to relive particular moments when the headset lastly arrives.
But what you won’t know is that, with a bit effort, you’ll be able to view this 3D video and not using a headset, albeit at not practically the identical constancy because the Vision Pro. And that’s what we’ll be having a look at right here.
A quick 3D primer
Believe it or not, the search for 3D picture seize goes again to the period of Thomas Edison and past. Stereoscopic units just like the kinetoscope used nonetheless pictures from two cameras mounted subsequent to one another after which seen as a flip e book by means of a set of goggles. These codecs have been primarily curiosities till the Nineteen Fifties when 3D films have been produced within the now-iconic anaglyph format, with filmed imagery from two cameras dyed purple and cyan and projected by way of side-by-side synchronized projectors.
A viewer sporting purple and cyan-filtered glasses might understand depth by having every eye view one of many two views projected on a flat display screen. Popular 3D films from the period included House of Wax and It Came from Outer Space. The craze proved short-lived because it was technically advanced for exhibitors and considerably uncomfortable for audiences.
3D noticed further temporary revivals from the Sixties to the Nineteen Eighties with films like Jaws 3-D and Spacehunter: Adventures within the Forbidden Zone. Unfortunately, lots of the movies centered on the impact itself and will have benefitted from higher scripts. So, the format remained area of interest.
Later efforts within the Nineties introduced improvements equivalent to IMAX massive format 3D seize and polarized glasses. Polarized glasses labored with a synchronized projector to offer a full-color—albeit considerably dim—picture that proved extra immersive and fewer fatiguing to viewers. However, the format additionally remained area of interest in comparison with typical 2D 35mm theatrical releases.
Everything modified in 2009 with the discharge of James Cameron’s Avatar, a landmark achievement in 3D cinematography and hyperrealistic computer-generated imagery. While the 3D format remained optimized for polarized glasses, the scope of the storytelling and breathtaking imagery proved extremely well-liked, and Avatar stays the highest-grossing film of all time.
Avatar ushered in a brand new period of digital 3D seize and main theatrical releases. It additionally led to new 3D residence projectors and televisions with lively shutter 3D glasses, which enabled a better high quality and brighter residence viewing expertise.
Interest in 3D films has tapered off since then, although it stays extremely well-liked in some markets, equivalent to Asia. But one factor is obvious: the continuing makes an attempt to drive 3D media point out that producers consider there’s nonetheless an urge for food for 3D so long as the immersion and emotional engagement is enough.
Whether the Vision Pro and its capability to retailer and share 3D experiences in 8K high quality meets these expectations stays to be seen.
The Vision Pro’s Immersive Videos
Apple’s Immersive Videos format is a particular container for 3D or “spatial” video. You can seize spatial video to this format both through the use of the Vision Pro as a head-mounted digicam, or with an iPhone 15 Pro or 15 Pro Max. The headset gives higher seize as a result of its cameras are extra optimized for 3D, leading to increased decision and improved depth results.
However, it should probably be extra socially awkward to seize in most conditions whereas sporting the headset till its look turns into extra commonplace. The iPhone trades in technical high quality for a much less off-putting expertise.
While the iPhone wasn’t designed particularly as a 3D digicam, it might probably use its major and ultrawide cameras in panorama orientation concurrently, permitting it to seize spatial video—so long as you maintain it horizontally. Computational images is used to compensate for the lens variations, and the output is 2 separate 1080p, 30fps movies that seize a 180-degree discipline of view.
This won’t be a match for the stereoscopic 8K that the Vision Pro is able to—which requires a dearer, a lot bulkier setup—however fairly spectacular for the digicam in your pocket.
MV-HEVC: The Vision Pro’s spatial video format
These spatial movies are saved utilizing the MV-HEVC (Multi-View High-Efficiency Video Coding) format, which makes use of H.265 compression to crunch this right down to roughly 130MB per minute, together with spatial audio. Unlike standard stereoscopic codecs—which mix the 2 views right into a flattened video file that’s both side-by-side or prime/backside—these spatial movies are saved as discrete tracks inside the file container.
This helps to take care of compatibility with non-stereo units, which might in any other case show each views concurrently. So opening a spatial video clip on an iPhone, iPad, or a desktop Mac will play simply one in all these video channels as a typical flat 1080p, 30fps video. To view each encoded angles in native 3D/stereo at full decision and full shade, you’ll want a Vision Pro. Or you’ll be able to see them in anaglyph purple/cyan 3D with a bit conversion magic, which we’ll get into in a bit.
How to Capture Spatial Video on an iPhone
Use the next steps to document spatial/3D clips on iPhone 15 Pro/Pro Max or larger:
- Ensure your iPhone is up to date to iOS 17.2 or later in Settings->General->Software Update.
- Next, go to Settings->Camera->Formats and allow Spatial Video for Apple Vision Pro.
- Then, open the Camera app and swipe to Video mode.
- Hold your iPhone horizontally and press the icon that appears like goggles.
- Next, hit the Record button, and also you’ll be recording a spatial video.
Here are some suggestions for getting the most effective spatial movies, i.e., clips that would be the most comfy and immersive when seen in 3D.
- Shoot with loads of mild, i.e., daylight or some lights at night time. Avoid full close to or full darkness.
- Compose the foreground and background rigorously.
- Make certain there’s loads of distance between the foreground and background. If the general depth within the body is minimal, it should look extra flat when seen in 3D.
- To emphasize depth, attempt to have one thing very near the digicam inside a couple of toes and a background that’s not less than 5 toes away or extra.
- Move slowly and easily. Remember, that is presupposed to symbolize an individual’s direct POV. Consider utilizing a tripod or a stabilized gimbal to clean out your shot as a lot as doable, or follow transferring and bracing the digicam in addition to you’ll be able to.
- Ideally, don’t transfer in any respect. With sufficient object motion and depth in sight, a totally locked-off digicam can present an ideal sense of presence.
- Shoot at a pure eye degree. Avoid a super-high or a low angle perspective except you’re aiming for a hen’s or bug’s eye view.
- Consider whether or not the viewer at a human scale will likely be seated or standing. The objective is to recreate a “you are there” expertise.
- When you’re completed, cease recording. You’ll discover your video in a brand new Media Type album within the Photos app referred to as Spatial.

- Put in your 3D glasses. It may take a bit in your eyes to regulate to the diminished brightness and restricted shade, however if you happen to’ve adopted the steps, you need to understand depth within the clip.
- To export the clip as a QuickTime film, click on the Share icon within the prime proper of the preview window.
- Choose the Anaglyph Format. If the depth doesn’t appear appropriate, toggle the Horizontal Disparity Adjustment on or off.
- Hit the Export button and select a location to avoid wasting the exported Anaglyph clip.
Anaglyphic 3D video samples
I’ve transformed my assortment of spatial video samples utilizing this system and you’ll obtain them from right here.
Viewing anaglyphic spatial content material
- The clip can now be seen in any QuickTime-compatible participant.
- The clip may also be edited in any NLE as a result of the 3D impact is now “baked in.”
- Remember to not do extreme shade grading as a result of you’ll be able to muddle the purple/cyan tinting of every angle essential to protect the 3D impact.
Conclusion: Will 3D Catch On (Again)?
Sharing spatial reminiscences has the potential to be a killer app for Vision Pro as a result of they’re so immersive and may present a deep emotional connection. It seems like you might be by some means reliving a waking dream as a substitute of simply a video. It will likely be fascinating to see how this new spatial ecosystem develops and what further experiences Apple has in retailer for Vision Pro customers sooner or later.
By reportedly promoting out its preliminary provide rapidly, Vision Pro is clearly successful story for Apple. But just some can afford it or are prepared for one. This workflow is only a style of what’s doable with the total headset. Seeing a preview of spatial video by way of this extra accessible technique may simply persuade you that this can be a product for you.
It also needs to be talked about that you simply don’t really want a Vision Pro to view spatial video in its native format—Meta’s Quest 2, 3, and Pro VR headsets additionally assist spatial video playback—as demonstrated by the video under. And whereas Meta won’t be doing this for altruistic causes, it’s excellent news for the format, increasing spatial video’s person base from the estimated first run of 150,000 Vision Pro headsets to the reported 20+ million Quest headsets already sold.
