Convert 2D Video to 3D Video

StereoLift accepts most common video upload formats, including MP4, MOV, MKV, WebM, AVI, MPEG, TS, OGG, FLV, and 3GP. We check the real video stream after upload, not just the file extension, so support also depends on the underlying codec and metadata. Your final 3D file is delivered as Full SBS, usually in MP4 for broad playback compatibility, or in MKV when that better preserves the source audio and packaging. Our goal is to keep the result as close to the source as practical, including resolution, frame rate, audio, and color behavior where the supported pipeline and playback format allow it.

Most jobs are typically faster than real time for videos up to 30 fps. Higher resolutions, higher frame rates such as 60 fps or 90 fps, and current compute availability can increase processing time. The calculator gives the best estimate for your specific video before checkout.

StereoLift is designed for convincing, comfortable 3D with depth that stays stable from frame to frame, while still keeping conversion fast and affordable. The goal is to preserve the original video cleanly instead of forcing an exaggerated effect. As with any 2D-to-3D conversion, difficult scenes can still produce occasional artifacts, especially around fine edges, fast motion, reflections, or partially hidden objects. In those cases you may notice things like edge artifacts or double outlines. The sample previews on our site show the kind of 3D presentation we aim for, but final results will still depend on the source footage.

Usually yes, especially in dedicated 3D-capable software players and VR headset apps that support side-by-side stereoscopic playback. Compatibility is strongest on Meta Quest, Pico, Apple Vision Pro third-party media players, desktop software players on Windows, macOS, and Linux, and mobile apps with dedicated 3D modes such as nPlayer on iPhone, iPad, and Android. On 3D TVs and projectors, results can vary because many older HDMI-based displays expect standard HDMI 3D modes rather than full-width side-by-side input. If automatic detection does not work, selecting Side-by-Side or Full SBS manually in the player or display is often enough.

StereoLift writes stereoscopic metadata for the delivered file, including container-level 3D flags and frame-level signaling. YouTube supports left-right side-by-side 3D uploads when an MP4 contains the metadata it expects, and supported YouTube VR and 3D playback paths can recognize the upload as stereoscopic after processing. Recognition and playback still depend on the platform, app, and device. If a player ignores the signal, the delivered file remains standard Full SBS and can be opened manually in a compatible 3D player. If you need a different behavior later, the free metadata tools can add or remove 3D recognition and display-shape metadata locally on your device without uploading the video again.

Full Side-by-Side places a full-resolution left-eye and right-eye view next to each other in one wide frame. For a 1080p source, that means a 3840×1080 3D output where each eye keeps its full original resolution. Unlike Half SBS, it does not cut each eye's width in half. It is also different from older Blu-ray 3D frame-packing formats, which were tied more closely to legacy disc standards and frame-rate limits. Full SBS is a practical modern format for high-clarity 3D playback at the full resolution and frame rate of the source.

The best playback method depends on your device. On Meta Quest and Pico, popular choices include SKYBOX, Pigasus, 4XVR, and Bigscreen. On Apple Vision Pro, use third-party apps such as SKYBOX, Moon Player, or Reality Player. For PSVR2, Rad TV supports stereoscopic side-by-side video. On Android-based TV devices such as Fire TV and NVIDIA Shield, Kodi is the strongest choice because it includes explicit stereoscopic 3D controls. On iOS and Android, nPlayer supports Full SBS via Settings → Video → Post Processing → 3D Mode. On Windows, PotPlayer has a built-in 3D mode reachable from the right-click menu; Bino is a free open-source alternative. On macOS, mpv is the most reliable option (mpv --vf=setsar=1:1 for cross-eye viewing, or --vf="stereo3d=sbsl:arcd,setsar=1:1" for anaglyph). On Linux, Bino is available via Flathub, and mpv supports the same flags. Without special software, StereoLift also offers a separate anaglyph conversion that plays in any regular video player with red-cyan glasses.

This is normal and your video is not broken. The file contains two full-resolution eye views placed side by side in one wide frame, with display-shape metadata, often called SAR or aspect-ratio signaling, that tells 3D-aware players how to display each eye at its correct shape. A regular 2D player follows this signaling and compresses the wide frame into the original aspect ratio, which makes both views appear horizontally squeezed. In some players, the embedded 3D signaling may cause the player to show only one eye as a regular 2D image instead. In both cases, all of the original image data is preserved. Any 3D-capable player or app will split the frame and display each eye at full resolution with correct proportions. If you want a plain wide SBS copy for a specific platform, the free metadata tools can remove that signaling fully on-device.

Usually, yes. StereoLift passes compatible source audio through without re-encoding, so the original audio quality is preserved. If the source contains an unsupported audio track that cannot be packaged safely, checkout warns you before you continue.

No. Privacy is part of the product design. StereoLift works without a traditional account and keeps data use focused on what is necessary to convert, deliver, and restore your order. Your browser keeps secure access details for your order locally, so returning to the same browser usually takes you straight back to your video. If you switch devices or clear browser data, you can restore access by email with a one-time magic link. Completed videos are generally available for 7 days from the time they become available.

Yes. Your files are encrypted during transfer and encrypted at rest while stored. We keep them private and use temporary download links instead of public file links. Source files are kept only to complete verification and conversion, and finished 3D videos are generally available for 7 days.

For paid orders, your payment method may be authorized at checkout first. The final charge is captured only after successful processing and final output checks. If the order cannot be completed, an uncaptured authorization is released instead of becoming a final charge.

When the free tier is enabled, eligible short standard conversions can be started without payment. Eligibility is verified on the server after upload and is limited to standard 8-bit Full SBS output, 720p-class output, and the current duration and frame budget. Preserve-10-bit, anaglyph, higher-resolution outputs, and longer or over-budget files remain paid. Usage limits may apply by user, network, and video.

Most standard videos work, but some files may still be rejected if their metadata cannot be read reliably or if they use format settings that are not currently suitable for stable 3D conversion. In many cases, re-exporting the video to a standard format such as MP4 is enough to fix the issue.

Every finished video goes through automatic checks before delivery, but no automated pipeline can guarantee that every difficult scene will be perfect. If you believe there is a technical issue with your result, contact support at support@stereolift.com with your order reference, a short description of the problem, and ideally screenshots or a short clip with timestamps from the affected scene. We can then review the case and, where appropriate, follow up with re-processing or another corrective step.

Pricing is per video and calculated from verified duration, frame count, resolution, and selected output profile. There are no subscriptions or monthly fees. Eligible short 720p-class standard conversions may be free when the free tier is available; all other conversions show the exact paid price before checkout.

StereoLift is priced to stay accessible because the service is highly optimized for efficient 3D conversion from start to finish. That keeps processing costs lower and lets us pass that efficiency on in the final price, while still focusing on clean results, reliable delivery, and a straightforward user experience.
