LightTwist lets you record & stream in a realistic virtual studio, even if your guests and co-hosts are remote. LightTwist is a virtual video studio that runs in Chrome, with a backend virtual production platform utilizing realtime computer vision for background removal and compositing, Unreal Engine 5 for rendering, and WebRTC for A/V streaming. It runs in realtime so you can live stream or record "live to tape", with a live preview so you see exactly what's getting streamed or recorded.
I started LightTwist in 2021 after seeing how Industrial Light and Magic built a huge 360 surround stage for the Mandalorian where they had a tracked camera and rendered the scene in realtime using Unreal Engine.
I’ve started a few computer vision companies (RedLaser, barcode scanning price comparison app - acquired by eBay, Twindo.com - FKA Occipital), so I thought there had to be a way to make virtual production much more accessible using computer vision and software engineering.
We’ve gone through several iterations, started as an iOS app for filmmakers, built a macOS app to be an awesome virtual camera for Zoom/etc, but have gotten a lot more traction once we positioned LightTwist as a virtual video studio and rebuilt it to run in the cloud.
We’ve signed an enterprise customer using LightTwist to power their video streaming platform (not yet announced!), and we’ve been iterating with other creators and studios including building a gameshow for Jimmy Fallon’s video production company.
We’re excited to be rolling this out publicly next week!
One thing I haven't seen asked yet: what happens if a remote guest's connection drops mid-broadcast, since the compositing is happening live over WebRTC? Does their feed freeze on the last frame, get swapped for a placeholder, or does the scene just drop them cleanly while the rest of the show keeps going? For an actual live show that failure mode matters more to me than lighting or CPU load.
How does the rendering hold up when you have like 4-5 remote guests all composited into the same virtual scene at once, any noticeable lag on the preview side?
Finally a chrome based virtual studio that doesn't feel like a gimmick. The Unreal rendered backgrounds look genuinely believable even with messy lighting from my home office.
how well does the background removal hold up with messy home lighting and no green screen, compared to something like OBS?
The browser-based setup is wild, no install needed and the Unreal-rendered backgrounds actually look believable on a webcam. Latency held up fine even with a remote co-host on my end.
How does the background removal hold up with messy home lighting or a busy bookshelf behind you, and is there a cap on how many remote guests you can bring in at once?
How does the background removal hold up with messy or low light webcams, and is there a cap on guest count before latency starts to bite?
The live preview that mirrors exactly what gets streamed is such a thoughtful touch, it takes the guesswork out of remote recordings and feels like something a real broadcast team would demand.
How does the browser-only setup actually handle realistic lighting on remote guests, or do they still need a green screen on their end?
The realtime Unreal Engine 5 rendering in Chrome is genuinely impressive - the fact that guests on slow connections still get composited cleanly without that awful smearing you usually see is a real feat of engineering.
How realistic does the virtual studio actually look on a typical webcam, and does the quality hold up if someone's lighting is bad or they're using a built-in laptop camera?
How does the background removal hold up with messy or uneven lighting in a home office setup? Curious if it needs a green screen or if regular webcam footage actually looks clean enough for a professional-looking stream.
The live-to-tape mode with a preview of exactly what's being composited is what sells this for me, not seeing the final key/comp until after the take is what makes green-screen streaming painful. Two day-one questions: since the UE5 rendering and compositing run on the backend and come back over WebRTC, is there noticeable lag between what I do on camera and the preview I'm reacting to? And when I record live to tape, do I get a full-quality composited file locally, or is export a separate re-render step?
How well does the realtime compositing hold up with more than four remote guests on screen at once? Curious if performance dips or if it scales cleanly with Unreal doing the heavy lifting in the browser.
how does the realtime compositing actually hold up when you have like 4-5 remote guests all talking at once, does it start to lag or fall apart?
Ran a quick test with a friend and the background replacement actually felt believable, not that flat cut-out look you usually get from browser tools. Nice that you can tweak the scene live while recording.
Congrats @vikasreddy for the launch, loved testing out the product!
Which creator segment is pulling hardest right now, streamers, podcasters, or course makers?
Very cool product! My one question is how demanding is it on CPU/GPU for the host? I think my laptop would be fine, but my PC is pretty dated so I'm curious.
