This page explains how to convert 2D media into 3D media in LeiaPlayer.
2D to 3D conversion couldn't be simpler. Simply open your 2D image or video in LeiaPlayer and tap on the Leia View Switch in the bottom left hand corner. Voila, your file is now viewable in 3D!
For images, a 3D copy of the image will be made in the LIF format, so you'll now have the original untouched 2D file as well as a 3D LIF copy.
For video, the conversion is done in real-time and your 2D video file will remain untouched. You will need to follow the above process each time you return to your video if you'd like to view it in 3D.
If your file is a Portrait Mode image from iOS with an Apple Depth Map, the embedded depth map will be used in the 3D conversion.
To learn more about the different filetypes, go to Supported Filetypes in LeiaPlayer.
You can edit 3D Depth and 3D Focus in LeiaPlayer.
This is only available for 3D images converted from 2D
The Depth slider controls the gain value of your image. As you move the slider up, you will perceive more depth
3D Depth adjusts the difference in image location of the same 3D point when projected under perspective to two different camera views. The perception of depth arises from the “disparity” of a given 3D point in your right and left images
This is available for all 3D images.
The 3D Focus slider controls the convergence values of your image.
As you move the slider down so the percentage values go more negative, more objects in your image will appear to be popping out in front of the screen
As you move the slider up so the percentage values go more positive, more objects in your image will appear to be moving backward into the screen
The convergence value is the point at which the left and right eye images align, which sets the location of convergence on the screen plane
Objects in front of this point will appear to be in front of the screen and those behind will appear to be behind the screen
LeiaLink is a feature of LeiaPlayer that allows you send pictures directly from your linked smartphone to your Lume Pad.
The LeiaLink tab on the side of LeiaPlayer allows you to connect your smartphone to your Lume Pad. Then, you can easily send pictures to your Lume Pad from your mobile device and they'll appear in 3D in LeiaPlayer.
It's easy!
Go to the LeiaLink tab in LeiaPlayer
Sign in using your Leia Account
You'll see a security code on-screen to enter on your mobile device then.
Now grab your mobile device.
On your mobile device, go to your device's app store and download LeiaLink
Open LeiaLink and follow the instructions on the screen
Type your Leia Account's email address into the LeiaLink app
Type the security code on your Lume Pad into the LeiaLink app
Your mobile device is now linked to your Lume Pad, and can seamlessly transfer images to your 3D tablet.
Now you can go to the image gallery on your smartphone, select images, and share them with the LeiaLink app. They will appear in the LeiaLink tab in LeiaPlayer on your Lume Pad, except they'll be in beautiful 3D!
This page explains which filetypes can be played back and edited in LeiaPlayer.
All of the following filetypes are supported in LeiaPlayer. It's organized by whether the filetype is 3D or 2D, and then further divided by whether it's an image or video. All 3D formats are automatically detected as 3D, either through the file's metadata or through an automatic computer vision algorithm for unlabelled 3D files.
Leia Image Format (LIF)
Leia Image Format images (abbreviated as LIF) are JPG images with image metadata that may contain depth, bokeh data, and one or more images known as "views"
These images can be shared anywhere to any device and will automatically show as a high-resolution 2D image on all standard computing devices like laptops or phones. However, they will automatically be displayed as 3D images on Lume Pad and other Leia devices
They are optimized for 3D Mode by default
This is the default image format in the Leia ecosystem, and offers the most flexibility long-term. When you edit an SBS image in LeiaPlayer, it will automatically save as LIF
3D SBS Images
Two Side-By-Side images
Left eye image on the left, right eye image on the right
File formats supported: JPG, PNG, WEBP, HEIC
Apple Portrait Mode Images
When a user takes a Portrait Mode image on an iOS device using the iOS Camera app, it may include an embedded depth map making it a true 3D file. If LeiaPlayer finds a depth map in a photo from iPhone, you can convert the file to LIF by simply tapping the 3D View Mode button
Tip: You can tell if a depth map will be captured when taking a photo in Portrait Mode on the iOS Camera app if the icon that says "NATURAL LIGHT" on-screen turns yellow. If it's grey, no depth will be captured
Tip: Newer iOS devices and especially iOS devices with LiDar take the highest-quality depth maps. Older devices may not be able to capture depth maps or will take poor quality depth images
Legacy 3D Images
Support for MPO and JPS filetypes
Support for two images embedded in an MPO or JPS image (files with 1 or 3+ images may not be supported)
They look like standard 2D images on many non-3D devices
MPO is most commonly captured on Fujifilm FinePix Real 3D cameras, Nintendo 3DS and 2DS devices, and other 3D cameras from that era
JPS is most commonly captured using Nvidia 3D Vision tools, such as in-game screen captures, and from other 3D software for PC
Automatic Detection of SBS images:
In the case that the automatic file detection feature didn't correctly identify your your SBS image and shows it in 2D as two side by side images, you can force LeiaPlayer to treat image files as SBS by using the Manual 3D Tagging feature inside the app or by doing the following:
SBS: Append "_2x1" to the end of the filename before the file extension
Half-width SBS: Append "_half_2x1" to the end of the filename before the file extension
Leia Video Format (LVF)
Leia Video Format images (abbreviated as LVF) are MP4 images with metadata that may contain a depth map and/or one or more video tracks known as "views"
These videos can be shared anywhere to any device and will automatically show as a high-resolution 2D video on all standard computing devices like laptops or phones. However, they will automatically be displayed as 3D videos on Lume Pad and other Leia devices
They are optimized for 3D Mode by default
This is the default image format in the Leia ecosystem, and offers the most flexibility long-term. When capturing a video in LeiaCam, it will automatically save as LVF
3D SBS Videos
Two Side-By-Side videos
Left eye image on the left, right eye image on the right
File formats supported: MP4, MKV, WEBM, H4V
SBS videos will open in 3D View Mode when viewed in LeiaPlayer on Lume Pad.
Automatic Detection of SBS videos:
In the case that the automatic file detection feature didn't correctly identify your your SBS video and shows it in 2D as two side by side videos, you can force LeiaPlayer to treat video files as SBS by using the Manual 3D Tagging feature inside the app or by doing the following:
SBS: Append "_2x1" to the end of the filename before the file extension
Half-width SBS: Append "_half_2x1" to the end of the filename before the file extension
These standard 2D image formats are supported in LeiaPlayer. You can also automatically convert any of them into 3D by tapping the 3D View Mode button in the view switcher in the bottom left of the UI. This will create a LIF copy of the image.

LeiaPlayer is a simple yet powerful app that lets you view and organize your 3D media. It supports playback of all your favorite 2D media too! And best of all: it can convert your 2D photos and videos into 3D in an instant.
When you launch LeiaPlayer, you’ll find yourself in the Media gallery. The app launches directly to Media so you can easily find the images or videos you've engaged with most recently.
Media shows you all the images and videos found in your Pictures, Movies, and Downloads folders as well as any file you navigate to and open in LeiaPlayer's File Browser. You can easily remove any file from your Media tab by selecting it inside the Media tab and choosing "Remove Selection From Media". You can also easily add any file on your device to the Media tab by finding it in LeiaPlayer's File Browser and selecting "Add Selection to Media".
If you're opening LeiaPlayer for the first time, you’ll notice some preloaded media to give you inspiration on what 3D content can look like. Note: Media will automatically add photos and videos found in the top level of your Pictures, Movies, and Downloads folders, but will not automatically add files in nested folders found inside those listed folders.
Tap the Menu Button (a.k.a. Hamburger Menu) in the top left to access the Navigation Menu Drawer. From here, you can jump between different file galleries in LeiaPlayer.
Moving down the drawer menu below Media, you'll see Camera Roll, File Browser, Lume Link, and Settings.
This is the default browsing experience in LeiaPlayer. The Media tab aggregates media on your device in one easy to use place. By default, all the image and video files in your Pictures, Movies, and Downloads folders will appear here. However, other files that you've opened in the LeiaPlayer File Browser will appear in Media automatically too, as well as media you've added using "Add Selection to Media".
file-browsingThis section shows you the entire file system of your device. The LeiaPlayer File Browser follows the standard file browsing paradigm from Android. The File Browser shows the folders on your device, and these folders contain subfolders within them. When you tap the “Pictures” folder you will see the “Screenshots” subfolder contained within it, alongside any media that's already in the Pictures folder.
We want to preserve this folder structure so that when you move files on or off of Lume Pad from a computer or another app, you can easily understand where they're located.
LeiaLink is an app on iOS and Android phones that lets you send images from your phone to your Lume Pad and have it waiting for you in LeiaPlayer already converted into 3D. You'll find the images waiting for you under the LeiaLink tab in LeiaPlayer.
The Settings tab in LeiaPlayer gives you the ability to turn features on and off and customize your LeiaPlayer experience.
General: This section provides several options for how you'd like to view media in LeiaPlayer. It also gives you options on how you'd like LeiaPlayer to handle certain features that may make modifications to your files.
Video Playback: Options for default video playback behavior.
About: Licenses and legal info.
LeiaPlayer Beta: Sign up for future Beta versions of LeiaPlayer.
There are a variety of ways to add media to your Lume Pad, including downloading files from the internet or getting a 3D photo or video from another Lume Pad user. To add media from a computer to Lume Pad to experience in LeiaPlayer, you can use Android File Transfer on MacOS or simply plug your Lume Pad into a PC to move files from your computer onto Lume Pad. Then, you can find them in LeiaPlayer and view them.
All 2D or 3D content can be viewed in 3D in LeiaPlayer! For 3D content it's self-explanatory, but for 2D images and videos it's a little different. Still, it's as easy as tapping the 3D button in the bottom left corner.
2D Images: Open a 2D image so it's full screen in LeiaPlayer. Tap the Leia logo in the bottom left-hand corner on the View Switcher, and a new LIF format version of your image that's in 3D. You will have two files now: the original 2D image and the new 3D LIF image.
2D Videos: Open a 2D video so it's full screen in LeiaPlayer. Tap the Leia logo in the bottom left-hand corner on the View Switcher, and after a few seconds of buffering, you will see your video playing back in 3D! Just follow these steps again whenever you want to view your 2D video file in 3D.
The Ellipsis Button is the three vertical dots you usually see in the top right corner of the app. The Ellipsis Menu changes depending on the context of where you are in the app.
The Ellipsis Button opens up View Options if you're in a standard Gallery View. These View Options may be available in other modes too, like in Bulk Selection Mode. These are the options available within the View Options menu:
3D/2D Sorting: Show only 3D media files, only 2D media files, or Both.
Media Type Sorting: Show only Images, only Video, or Both.

Tap the Move Button in the More Options Menu.
In the Move Menu, navigate to the destination folder you want to move the file(s) to.
Tap the Move Here Button in the bottom right corner to confirm the move.
The files will now be located in the destination folder you selected.
Viewing 3D images
If you have 3D files captured from other devices like SBS images or video, LeiaPlayer will try to detect them automatically. However, sometimes, LeiaPlayer may not automatically detect them as 3D. To manually communicate to LeiaPlayer that the files are 3D, you will need to use the 3D Tagging feature.
Here's how to do this in LeiaPlayer:
Open up the 3D image that's being displayed in 2D
Tap Ellipsis Button (3 vertical dots) icon in the top right corner
Tap Add 3D Tag
Follow the instructions and answer questions about the file
The file will now be viewable correctly in 3D
When you open an image or video in LeiaPlayer, it will open in Theater Mode. This is the best place to view 3D media.
When viewing media, you will notice an option in the bottom right corner to change the view mode.
3D: View the compatible image or video in 3D Mode.
2D: View the image or video in standard 2D Mode.
Some Apple devices allow you to capture depth maps when shooting images in Portrait Mode and with some other apps. The quality of the depth map depends on the device, the sensors available, and the environment and distance from the subject when the image was taken.
Shoot Portrait Mode Images on your iOS device where the Portrait Mode Indicator (e.g. Natural Light icon) is yellow
Move images with Apple Depth Maps and move them to your Lume Pad (using LeiaLink, email, or other methods)
Open it in LeiaPlayer
Tap the 3D View Button to convert Apple Depth Map images to a 3D LIF

In order to share Leia Image Format (LIF) files to another Lume Pad device and retain the 3D metadata, you must choose the transfer method you use wisely. Many messaging apps and social networks will strip the 3D metadata and send only a 2D image to the other user.
If you'd like to send the LIF file directly to another device here are some methods that work:
Android Nearby Share
Supported Messaging Platforms
Discord
ZIP Archives: If you compress or ZIP your LIF images before sending them, metadata will be retained in transit
If you want to share your 3D images with 2D devices, tap the share button on the gallery screen.
This will allow you to export images as Depth Animation in MP4 and GIF format, which are 3D-synthesized animations that show the depth of your images by interpolating smoothly between the image's views.
This is the best way to share your 3D images on traditional social media platforms.
Loop Video
To loop your video continuously, tap the ellipsis button in the top right corner
Then tap “Loop Video On”
Depth Slider
You will see the Depth Slider on the right-hand side of the screen whenever viewing video content in 3D mode
Move the Depth Slider up and down to increase or decrease the disparity value, which will increase or decrease the sensation of depth
What are the benefits of editing 3D Images in LeiaPlayer?
Improve the 3D visual quality of your images
Increase the depth effect of your images
To edit images in LeiaPlayer, open an image and tap the pencil and pad icon in the bottom center of the screen. Only some 3D images can be edited, including LIF and 3D SBS images.
The LeiaPlayer editor relies on the depth map to estimate the depth at each pixel in the photo, which can be used to identify portions of the image that are far away and belong to the background.
Images are saved in the Leia Image Format and will retain the same number of views as it originally contained.
The Camera Roll is a folder of all the pictures and videos you've taken using camera apps on the device, including those taken with .
To use the LeiaLink feature, you must log in using your , and link your device to the LeiaLink app installed on your mobile device.
