Which route fits your 3D files

Last checked November 2, 2026: each app's page, version notes and forum.

Which to pick: FramePlayerX if the film lives on the headset or a server and you accept an unofficial app. Whirligig if you want to stay inside Steam. The PC route if your films already sit on a gaming PC.

Play a 3D file on the headset

FramePlayerX: uses the hardware decoder

FramePlayerX is a free, open-source player, not affiliated with Valve, that "runs natively on the headset" [3].

1. Download it. Open the project page in the headset's browser and press Desktop Mode [3].
2. Install it. Open Install-FramePlayerX.desktop from Downloads and confirm. It adds itself to your Steam library, and Steam may close for a moment [3].
3. Add your films. Start it from the Steam library, then choose a file on the device or add a source [3].
4. Set the layout. Add _SBS or _TB to the file name, or open ⚙ › Format. It remembers your choice for that video [10].

Whirligig: stays inside Steam

Whirligig is a paid Steam app with "Side-by-Side (SBS) and Over/Under (OU) support" [5]. Its maker says the Android build "runs better than the Windows version through Proton" [4]. Lepton is the layer that runs Android software on the headset [9].

1. Open Properties. In your Steam library, open Whirligig and press the gear.
2. Choose Lepton. On the Compatibility tab, turn on "Force the use of a specific Steam Play compatibility tool" and pick Lepton [4].
3. Press Play. Close Properties, let Steam download the Android version, then start it [4].

immerGallery: one purchase for both versions

immerGallery lists a "standalone Steam Frame" version, and "No connected PC is required" [6]. One purchase on Steam includes the PC and Frame versions [6]. Its makers tested version 1.4.5 in September 2026. A 3D film file at 1080p per eye played smoothly, and so did 4K at 60 fps. 6K hung and 8K was not smooth [7].

Stream from a PC

Valve calls the headset "streaming-first" and includes a wireless adapter [11]. Bigscreen's Steam page says you can watch "in side-by-side 3D or over-under 3D directly from your desktop" [12].

1. Test ordinary PC VR first. Run a game. Start at 90 Hz [13].
2. Change one SteamVR setting. Turn off Settings → Advanced Settings → Dashboard → Present Non-VR Applications on Theater Screen Upon Launch [13].
3. Launch Bigscreen through SteamVR and show your Windows desktop [13].
4. Play the film full-screen and set its layout to SBS or OU in Bigscreen. These desktop modes read half side-by-side and half over-under, not full side-by-side [13].

Those steps come from the maker of Stream to 3D, a rival converter. Whirligig also runs as a PC app [4]. With another headset, see Steam Link on a Quest or PS VR2 on PC.

When the picture looks wrong

• Two pictures side by side. The film is on a flat screen, not in a 3D player. Open it in an app above and set the layout. Terms: 3D video formats.
• Two squeezed pictures in a normal 16:9 frame. That is half side-by-side. FramePlayerX treats full-width files (3840x1080) as 3D by their shape, but 16:9 shapes play flat [10]. Set the layout by hand under ⚙ › Format.
• The same picture in both eyes. One owner saw this on a SKYBOX beta, not on the stable version [17].
• Stutter. In FramePlayerX it is usually AV1 or 4:2:2 video, which the hardware decoder cannot play [3]. In Lepton apps, drop the resolution or stream from the PC [4], [7].
• A microSD card or USB drive is not seen. Lepton apps need Developer Mode, ADB and a helper script, and the card should be exFAT [8]. FramePlayerX reads both directly [3]. In Whirligig the mapping resets when the app restarts, by one owner's report [16].
• The battery runs out. Engadget reports about two hours of video streaming [14]. You can run it on a USB-C charging cable [14].

What it cannot do yet

• A system 3D mode. Valve's words: "we don’t currently support it, but it’s on our list" [2]. An owner asked for an "Off / 3D SBS / 3D Over-Under" toggle on October 29, 2026 [1].
• 3D Blu-ray discs. This page covers video files. For discs, see 3D Blu-ray players.
• Turning flat games into 3D. Valve told Road to VR in 2025 that this is not something it is looking into [2].

A film with no 3D release

If the film only exists in 2D, a 3D player has nothing to show in 3D. Owl3D's converter runs on a Windows PC or Mac and makes a side-by-side, half side-by-side or top-bottom file from a 2D video you have the right to use. That is an AI conversion, not the studio's 3D version, and a full film takes time. Play the result in any app above. We have not tested it on a Steam Frame. The free tier adds no watermark and stops at 60 seconds per conversion; see pricing.

Two other options exist. immerGallery's site lists cloud 2D-to-3D conversion [15], and we could not confirm it on the Frame version. Stream to 3D converts live on a Windows PC, and its maker says it "is not currently a native Steam Frame system-wide conversion filter" [13].

What owners report

Five accounts from Steam forums, September and October 2026. We have not tested them.

• DeoVR, streamed from a PC: "at least the video itself plays smoothly" [18].
• DeoVR, on the headset: "unuseable right now on steam frame. horrible resolution and lag" [18].
• SKYBOX, streamed from a PC: on a beta, full side-by-side films "show the same image to each eye". The same owner wrote: "The current (non beta) version plays them all fine." [17]
• SKYBOX, on the headset: "as soon as I try to pause, or skip forward or back, I get a "waiting" screen that does not end" [20].
• Whirligig 5.8103 beta, streamed from a PC: half side-by-side failed to stretch in a 3D environment. Its developer replied: "A fix should be in the next release" [16].

FAQ

Can the Steam Frame play 3D movies without a PC?

Yes. FramePlayerX [3], Whirligig [4] and immerGallery [6] all run on the headset itself.

Can I watch 3D movies from Plex or Jellyfin?

FramePlayerX connects to Jellyfin and Emby [3], and added Plex in a beta on October 31, 2026 [19]. Whirligig's Steam page lists Plex over local and remote connections [5], and its version notes name Plex and Jellyfin [4].

Where do I get 3D movies if I own none?

Bigscreen says you can "rent and watch high quality 3D movies in VR" [12], though its page does not mention the Steam Frame. See free 3D videos and where to watch 3D movies at home.

Is a Steam Frame or a Quest 3 better for 3D movies?

immerVR's test favoured the Quest 3 for 8K VR180, and found the Steam Frame smooth up to 4K and with 1080p-per-eye 3D films [7]. Note that immerVR makes immerGallery. For the Quest route, see watching movies in VR.
