Most AI video tools ask you to give up control. You type a prompt, you cross your fingers, and the model decides what your shot looks like. Beeble’s SwitchX 2.0 flips that deal. It takes footage you already shot, keeps the actor and the performance untouched, and rebuilds everything else — the light, the background, the props, the costume — in native 4K. Change what you want, keep what matters.
The Story
Beeble is not a hype shop. It is a five-person research studio out of South Korea, founded in 2022. The team built its own light stage — a physical rig that captures how light wraps a real face — and used it to train their models. Their relighting research was published at CVPR 2024, one of the top computer-vision conferences. That is the pedigree behind the tool.
Their first hit was SwitchLight: point it at any clip and it relights the actor to match a new HDRI, the same way you would light a scene in Blender or Unreal. SwitchX is the next step. Instead of only fixing the light, it transforms the whole video. You can swap the set behind your actor, change the time of day, restyle a jacket, or drop the same take into a different world — and the person on screen still looks and moves like themselves.
Version 2.0, out this month, is the biggest jump yet. Beeble calls it their largest upgrade to the video-to-video model. The headline numbers:
- Native 4K output, up from 1080p.
- Clips up to 20 seconds at 24fps — long enough for a real shot, not just a test.
- 10-bit color, so the footage survives a proper grade.
- Better camera tracking that stays glued to your source movement.
- Improved lip sync and fast-motion handling.
- A smart up-res workflow: iterate cheap at 720p, then commit to a final 4K render.
It all runs inside Canvas, Beeble’s node-based compositing environment. If you think in nodes — and if you use ComfyUI or Nuke, you do — this feels like home. There is even a 3D Scene Generator in the ecosystem powered by World Labs, so you can build a place and then shoot your actor into it.
Why You Should Care
This is the AI video problem everyone in VFX keeps circling: how do you get generative power without losing the shot you fought to capture? A director does not want a “similar” actor. A client does not want the logo redrawn. SwitchX 2.0 is a bet that the winning tools are the ones that preserve identity and performance and only touch what you point at.
For a small studio the math is brutal in your favor. A background you could never afford to build, a location you could never travel to, a costume change that would cost a reshoot — all become a node in a graph. And because the model was trained on light-stage data, the relighting sits on the face correctly instead of looking pasted on. That physical grounding is the difference between a gimmick and a shot you can put in a real edit.
Try It / Follow Them
SwitchX 2.0 is live now on the Beeble platform, cloud-based and browser-first. To mark the launch, generations run at 50% off through September 23, 2026 — a cheap window to actually stress-test it on your own footage.

IK3D Lab Take
We keep saying it: the AI tools that stick are the ones that hand you a dial, not a slot machine. SwitchX 2.0 is a clean example. It does not try to dream up your movie. It takes the frames you own and lets you re-light, re-set, and re-dress them while your actor stays your actor. That is control-first AI, and it is exactly the workflow a maker can build on. The light-stage training is the quiet flex here — it is why the result reads as a shot instead of a filter. Grab the 50% window and throw your ugliest handheld clip at it. That is the real test.
