NEX VR Player 3D Guide: Turn 2D Videos into Real-Time 3D on Meta Quest 3

When you revisit a favorite movie, a familiar music video, or one of your own home videos on the weekend, you may wonder what it would feel like if the people were no longer flat against the screen and had real distance from the background. Everyday clips—your child riding a bike for the first time, your family chatting in the yard, or your dog running toward the camera—can feel a little like stepping back into the memory when viewed in 3D.

That is exactly where the real-time 3D features in NEX come in. NEX is a 2D and 3D video player for Meta Quest that can add spatial depth to regular 2D footage during playback. If the content is running on your computer, its companion desktop app, NEX Link, can stream your PC desktop to the headset so you can enable real-time 3D there as well.

These are actually two different workflows. One processes a video playing directly in NEX, while the other processes the desktop image streamed from your computer. This NEX VR Player 3D guide explains both options and when to use each one.

Before you begin: Update NEX on your Meta Quest to version 1.2.2.0 or later. If you plan to stream your computer desktop, install and run the latest version of NEX Link as well.

What Are the Two Real-Time 3D Options in NEX VR Player?

Before you start, check where your content is coming from:

• The video is playing directly in NEX: Use AI 3D.
• The content is running on a Windows PC: Use NEX Link, PC desktop streaming, and real-time 3D.

If you simply want to watch a movie file that is ready to play, the first option is more direct. If you want to bring a game, browser video, or another computer app into Meta Quest 3, use the second option.

Method 1: Turn a Regular 2D Video into AI 3D on Meta Quest 3

This is the simplest method. Once the video is open in NEX, you can enable AI 3D without streaming your computer desktop or running NEX Link.

1. Open NEX version 1.2.2.0 or later.
2. Play a regular 2D video in NEX.
3. Bring up the playback controls and select the square icon in the bottom-right corner.
4. Select AI 3D.

NEX analyzes the picture and generates depth while the video is playing, but it does not permanently convert the original file into a separate 3D video. When you turn off AI 3D, the original video remains unchanged.

For your first try, choose something you already know well. Alongside movies and music videos, your own home videos are especially good material: a child walking toward the camera, a pet running in from across the room, or family members standing at different distances. These shots already have clear foreground and background relationships, so AI 3D makes the spatial separation between people, pets, and the background easier to notice. Because you know the footage, you will not have to stare at an unfamiliar clip and wonder whether the effect is working.

Method 2: Stream Your PC Desktop with NEX Link and Enable Real-Time 3D

Sometimes your content is not a video file you can open directly. It may be running in a computer browser, a game, or another desktop app. In that case, NEX Link can bring your entire PC desktop into the headset and apply real-time 3D to the streamed image.

1. Install and launch the latest version of NEX Link on your Windows PC, and keep it running.
2. Make sure your computer and Meta Quest are connected to the same network.
3. Open NEX in the headset, enter NEX Link, and connect to your computer.
4. Start PC desktop streaming.
5. Enable real-time 3D in NEX.

Once connected, the view in Meta Quest changes as you switch windows, play a video, or enter a game on your computer. It is more like moving your computer screen into NEX than converting and saving a new file first.

At present, PC desktop streaming requires a Windows PC with an NVIDIA GPU. If your computer uses an AMD GPU, you can still use the first method: play a regular 2D video directly in NEX and enable AI 3D.

Should You Use AI 3D or NEX Link Real-Time 3D?

The easiest way to remember it is: If the video file plays directly in NEX, choose AI 3D. If you want to bring your current computer screen into Meta Quest 3, choose NEX Link.

What If AI 3D Is Missing or NEX Cannot Find Your Computer?

If you do not see the AI 3D option, first make sure NEX is updated to version 1.2.2.0 or later and that you are playing a regular 2D video. Then reopen the playback controls and check the options under the square icon in the bottom-right corner.

If NEX cannot find your computer, check the following:

• NEX Link is open and running.
• Your Windows PC and Meta Quest are on the same local network.
• Windows Firewall allows NEX Link to access the current network.
• A VPN, guest network, or router setting is not preventing devices on the local network from discovering one another.
• NEX and NEX Link are both up to date.

If your computer has an AMD GPU, there is no need to keep troubleshooting PC desktop streaming. Under the current hardware requirements, opening the video directly in NEX and selecting AI 3D is the better option.

Start Your First Real-Time 3D Experience with a Familiar Video

The two real-time 3D features in NEX solve different problems. AI 3D is for playing an existing video directly, while NEX Link is for streaming whatever is happening on a Windows PC into the headset. Once you know where your content is coming from, the choice is simple.

Update NEX to version 1.2.2.0 or later and begin with a video you have watched many times. A familiar shot is often the best way to feel what changes when an ordinary 2D image gains a little more depth between the foreground and background.

Frequently asked questions

Why is there little or no depth after I select 3D?

Check the source first. Native 3D video needs the correct SBS or Top-Bottom layout; swap the left and right eyes if the depth looks reversed. Selecting a 3D layout for an ordinary 2D video does not create full stereoscopic depth by itself. See the NEX 2D-to-3D guide for the appropriate workflow.

Do SBS or Top-Bottom movies need to be converted again?

No. Play the file directly and select the layout that matches the source. AI 3D or 2D-to-3D processing is only needed for a normal single-view 2D video.
