Free 3D video conversion up to 4K

StereoLift is a cloud tool I built that converts regular 2D video into Full Side-by-Side stereoscopic 3D.

Since Bigscreen is one of the most relevant places to actually watch 3D Full SBS video in VR together, I wanted to share it here and ask for feedback from people who use Bigscreen regularly.

StereoLift currently offers limited free conversions for up to 10 minutes at 30 fps in <=4K. So you do not have to rely on a demo or marketing claim. You can upload your own 2D footage privately and see for yourself how the quality holds up in your headset and playback workflow.

The custom depth map based 3D conversion pipeline focuses on stable depth perception over time and controlled 3D view synthesis, so converted videos stay comfortable across motion, cuts, and longer clips. A broad range of different video formats and source codecs with high resolution spatial audio formats is supported. A recent addition is that now also variable frame rate video can be processed.

The output is a regular Full SBS video file, where the general policy is to maintain source quality and format as good as possible meaning HDR10 for HDR sources and preservation of original audio. Metadata for most easy playback and compatibility for YouTube 3D is added. However, this always depends on how well this metadata is processed by your playback device and maybe your player still requires specific selection of Full SBS for correct playback.

I also deliberately avoided a subscription model. I think per-video (per frame) pricing feels more honest to me: you see the price before checkout and pay only when you actually want a file converted and the file indeed converted successfully (you are only finally charged after automatic file verification). Larger conversion packages for heavier use are planned later, mainly to avoid repeated credit card fees leading to higher prices for short videos. But they are anyway free for up to 2 conversions per day and user...

StereoLift Demo Video

Hi everyone,

I recently came across this subreddit while reading about the new wave of consumer glasses-free 3D monitors. It immediately caught my attention because this kind of display is exactly where Full Side-by-Side video becomes useful again: the hardware is finally overcoming the need for 3D glasses, but there is just not enough native content to actually watch on it.

To solve that, I launched StereoLift, a web tool that converts standard 2D video into Full SBS stereoscopic 3D for glasses-free 3D monitors, 3D TVs, projectors, VR headsets, and platforms that support SBS playback.

The goal was to make high-quality 3D conversion practical without needing to set up a local GPU pipeline, install software, tune depth models, prepare playback metadata manually, or tie up your own GPU for high-resolution AI video processing. You upload a video, StereoLift processes it in the cloud, and you get a 3D-ready file back.

What you get back is not a gimmicky “depth filter.” I built StereoLift to close the gap between automated 2D-to-3D conversion and the stable, comfortable depth people expect from native 3D content.

What makes it different is how the conversion behaves in motion. StereoLift favors temporal stability over flashy frame-by-frame repair. Instead of relying on unstable hallucinated infill around every newly exposed edge, the pipeline focuses on steady video depth, scene-aware normalization, and controlled view synthesis. That helps reduce the glassy edge wobble and contour crawling that often make converted 3D hard to watch.

Difficult scenes can still show slight halos, and very thin details are limited by the effective resolution of the AI depth estimate. The difference is that StereoLift is designed to keep stretching and edge artifacts controlled and temporally stable instead of letting them flicker or crawl from frame to frame.

A few core features:

- Full SBS output, with a full-resolution left and right eye

- Up to 4K output

- HDR preservation for supported sources and output profiles

- Original audio preserved where compatible

- Support for common landscape, portrait, cinema, and social-video aspect ratios

- 3D playback metadata included for compatible players and platforms

- No subscription

- No account required

- Private uploads, encrypted in storage, with temporary download access

- Files are not used for training or sold

For a limited time, I’m also opening free promotional conversions for videos up to:

- 10 minutes at 30 fps

- 4K

If you have footage you would like to test on an Odyssey 3D or another SBS-capable display, I’d love for you to try it:

The demo video in 2D at the top can be watched here on YouTube in 3D: https://www.youtube.com/watch?v=fJxnmpRZis0

The video on YouTube is the direct output from StereoLift without any cutting and separate conversion of the shown scenes.

Disclosure: this is my product, and I’m not affiliated with Samsung. I’m sharing it here because people in this subreddit seem to care about exactly the kind of 3D playback quality StereoLift is built for. I’m also happy to hear honest, constructive feedback on what works, what breaks, and what would make the tool better for glasses-free 3D displays.

To be fair, it is not completely artifact-free: Difficult scenes can still show slight halos, and very thin details are limited by the effective resolution of the AI depth estimate. The difference is that StereoLift is designed to keep stretching and edge artifacts controlled and temporally stable instead of letting them flicker or crawl from frame to frame. Instead of letting errors flicker or crawl from frame to frame, the focus is on a stable, watchable 3D result that holds together across motion, cuts, high resolutions, and longer clips.

- Up to 4K output

- HDR preservation for supported sources and output profiles

- Original audio preserved where compatible, including surround formats where supported

- 3D playback metadata included for compatible players and platforms

- No subscription

If you have old footage, a short film, travel video, music video, product shot, or anything you’ve wanted to see in 3D, I’d love for you to try it:
