Quick start (first successful 3D)

  1. Open the docs hub and pick a workflow: Configuration Guide.
  2. In Stream to 3D, check Tools so your media player / FFmpeg paths are discovered correctly.
  3. Start with a short test clip and an easy, compatible output format like HSBS (Half Side-by-Side). See Settings → Format.
  4. In your player/device, enable the matching 3D layout (SBS vs TB/OU). Most “double image” issues are just a layout mismatch.
  5. If you see an LVE0xx error code at any point, start with Licensing & Activation and Error Codes. If you contact support, include logs from Logs & Diagnostics.

Choose your workflow

Stream to 3D supports multiple workflows. The right one depends on what you’re trying to do:

  • Play (real-time playback on your PC) — watch on your PC, often mirrored into a headset via Virtual Desktop/Bigscreen. See Real-time Conversion and Playback.
  • Stream (to a remote player/device) — send converted video over the network to another device/player. See Streaming.
  • Convert (make a 3D file for offline playback) — create a file to play later (often the most reliable for headset playback). See Video File Conversion.
  • Live capture (camera/screen capture → 3D) — for webcams, capture cards, or PC screen capture. Start with PC Screen or Live Video Conversion to 3D.

Licensing & activation

If Stream to 3D won’t start, says your license is invalid, or shows an LVE error code, start here:

Tools & dependencies

Recommended: use the dedicated checklist page first: Tools & Dependencies Checklist.

Most setup issues come down to tools/dependencies (players, codec packs, FFmpeg, plugins) not being installed or not being discovered correctly.

“It looks wrong” (layout/aspect/depth)

Recommended: see “It looks wrong” troubleshooting for layout/aspect/depth fixes and player/device 3D mode tips.

Double image / not 3D

  • Confirm your player/device is set to the same 3D layout that Stream to 3D is outputting (SBS vs TB/OU; Half vs Full). See Settings → Format.
  • Bigscreen: it only supports Half formats. Start with HSBS or HTB. Virtual Desktop supports Full SBS/TB as well as Half.
  • If you’re using a headset/player app, make sure you chose the correct 3D mode inside the app (many default to 2D).

Squished or stretched image

  • Aspect ratio handling differs by player/device. Review the Format settings (including “Force 16:9” behavior) in Settings → Format.
  • If you’re using a VR player, confirm it isn’t applying extra stretching/cropping.
  • Bigscreen: it expects a 16:9 input. If needed, enable “Force 16:9 aspect ratio” in Settings → Format (and choose whether to crop or pad).

Weak depth or uncomfortable depth

  • Depth and comfort are primarily controlled by Temporal Offset and the stabilisation settings (labelled “Stabilization” in the app). See Settings → Algorithm.
  • Fractional temporal offsets (e.g. 1.25) can be more CPU intensive because they rely on interpolation; if you need real-time performance, prefer whole-frame offsets.

Performance & stutter

Recommended: see Performance primer for quick improvements and the main bottlenecks.

  • Start with Half formats (HSBS/HTB) for compatibility and performance, then move up to Full formats if your hardware can keep up. See Settings → Format.
  • Frame-rate interpolation (doubling output FPS) is resource intensive and may not be practical in real time at high resolutions. See Settings → Algorithm.
  • If you can’t hit real-time in Play/Stream, consider converting offline (Convert) for the best quality and smoothness. See Video File Conversion.
  • If you are using live capture/screen capture, reduce the capture frame rate and/or capture region to match your hardware. See Screen Capture.

Streaming first checks

Recommended: for the dedicated checklist (with protocol notes and client/player gotchas), see Streaming first checks.

  • Start with HTTP streaming for best compatibility. See Streaming.
  • Test the stream URL on the same PC first (for example using VLC), using the exact URL shown in Stream to 3D.
  • If it works locally but not on your device: check your network (same LAN/Wi‑Fi), VPN, and firewall rules.
  • RTSP requires a server (e.g. MediaMTX) running while you stream. See Streaming protocols overview.
  • Subtitles are only supported over HTTP streaming.
  • On the client player/device, select the correct 3D layout (SBS vs TB/OU; Half vs Full).

Error codes (LVE0xx)

If Stream to 3D shows an LVE code, look it up here:

Common examples:

  • LVE022 — install limit reached (up to 3 machines). Contact support for an install-count reset.
  • LVE023 — communication error. Check your internet connection/VPN/firewall and retry.

Before contacting support

To get the fastest resolution, include the standard diagnostics bundle:

  • Your store (Steam/Gumroad/Itch/etc), and your Stream to 3D version.
  • The exact error code/message (e.g. LVE023).
  • Logs and key screenshots. See Logs & Diagnostics.
