Beeble SwitchX: Video-to-Video Generative Compositing Explained (2026)
Last updated August 7, 2026
Beeble SwitchX (Feb 2026) is a video-to-video generative compositing model from Seoul-based Beeble AI: it changes lighting, backgrounds, props, or wardrobe while keeping the subject pixel-grounded to source footage. Four mask modes (Auto, Select, Fill, Upload for external mattes) need no green screen; unmasked pixels are relit and harmonized. Output is 720p/1080p, and it runs inside the invideo agent.
Updated August 2026
What separates Beeble SwitchX from generic video restyling is where the pixels come from: it changes lighting, backgrounds, props, or wardrobe while keeping your subject pixel-grounded to the original plate — Beeble describes generation guided "directly by your source footage at the pixel level." The video-to-video generative compositing model, released February 6, 2026 under the tagline "switch anything, keep what matters," takes source footage, a reference image, and a prompt. No green screen is required, external mattes plug straight in, and it runs among the video tools in the invideo agent.
Who is Beeble AI?
Beeble is a Seoul-based startup founded in 2022 by ex-Krafton researchers, led by CEO Hoon Kim, with a $4.75M seed round in July 2024 per press reports. Its research lineage is relighting: SwitchLight was published at CVPR 2024 (arXiv 2402.18848), pairing a physics-driven Cook-Torrance architecture with self-supervised pre-training; SwitchLight 3.0 (November 2025) turns any footage into PBR render passes. The company won a Webby Award for AI & Machine Learning in April 2026. SwitchX is its first fully generative model — where SwitchLight estimates lighting passes for downstream compositing, SwitchX does the compositing itself, end to end.
How does SwitchX work?
Three inputs drive every generation: the source video, a reference image acting as the style, lighting, and mood blueprint (it can be AI-generated in-app and needn't match the plate), and a text prompt, with an Autopilot prompt-assist available. Masked regions are fully re-generated to match the reference and prompt; unmasked pixels are kept from the source — and, crucially, relit and harmonized so the untouched subject sits believably in the new lighting rather than looking pasted in.
The four mask modes
| Mode | What it does | Typical job |
|---|---|---|
| Auto | Detects and tracks the subject automatically | Background swap or relight around an actor |
| Select | Manual element selection | Wardrobe changes, prop switches, targeted inpainting |
| Fill | Whole-frame restyle that preserves scene geometry | Full-look changes, day-for-night style shifts |
| Upload | External alpha mattes from Nuke, After Effects, etc. | Pixel-perfect control inside an existing comp pipeline |
Upload mode is the professional tell: SwitchX accepts the mattes a VFX pipeline already produces rather than replacing the pipeline.
SwitchX specs
| Spec | Detail (as of August 2026) |
|---|---|
| Released | February 6, 2026 |
| Type | Video-to-video generative compositing |
| Inputs | Source video + reference image + text prompt |
| Output resolution | 720p or 1080p (cloud) |
| Frame rate / aspect | Source fps and aspect ratio always preserved |
| Mask modes | Auto, Select, Fill, Upload |
| Green screen | Not required |
| Availability | Cloud-only feature |
The defining row is frame rate and aspect: always preserved. SwitchX behaves like a compositor working on your plate, not a generator replacing it.
Why VFX pipelines take SwitchX seriously
Most AI video tools speak consumer formats; Beeble's stack speaks post-production. Its Nuke, Blender, and Unreal integrations predate SwitchX, Foundry co-published a Nuke tutorial for it in May 2026, and the companion model SwitchHDR (July 2026) reconstructs 16-bit scene radiance from 8-bit SDR footage and exports EXR sequences in ACES2065-1 — color-pipeline literacy still rare among generative tools. Adoption has spread beyond Beeble's own apps, too: in June 2026 a third-party creative platform shipped a VFX feature built on SwitchX.
Strengths and known limits
Strengths. Pixel-level grounding to source footage is the differentiator — identity and performance survive the switch, where prompt-only restyling drifts. The mask workflow scales from one-click Auto to externally-authored mattes, and the relight-and-harmonize pass solves the classic composite problem of subjects that don't match their new environment.
Limits. Cloud output tops out at 1080p as of August 2026 (Beeble's desktop Studio line supports 4K for other tools, but SwitchX is cloud-only). A documented quirk: the model only "sees" unmasked regions, so tracking markers inside a mask are lost, which can degrade motion inference even on simple linear camera moves. And per-generation credit costs aren't published, so cost-per-shot takes testing.
What should you use SwitchX for?
- Background replacement without keying — a heavier-duty cousin of the video background remover workflow, moving an actor into a new environment with relighting included.
- Actor and subject relighting — matching a subject to a new plate's lighting, the core AI VFX use case SwitchX inherited from its SwitchLight lineage.
- Wardrobe, prop, and scene switching — Select-mask changes to costumes or set dressing, or Fill-mode restyles, in a background change pass that would otherwise mean a reshoot.
Getting good results
Choose the reference image carefully — it, not the prompt, sets the lighting and mood, so pick one whose light direction roughly suits your subject. Use the narrowest mask mode that does the job: Auto for subjects, Select for elements, Fill only for full restyles. Keep tracking markers outside masked regions. And favor plates with clean subject separation; SwitchX needs no green screen, but it can't recover what the footage never captured.
SwitchX questions
What is Beeble SwitchX used for?
Generative compositing: changing backgrounds, lighting, props, or wardrobe in existing footage while keeping the subject locked to the source pixels — VFX-style shot surgery without keying or 3D.
How much does Beeble SwitchX cost?
Beeble's plans are Creator at $16/month, Professional at $60/month, and Team at $84 per seat/month (annual pricing, per the official site, August 2026), all credit-based. Per-generation credit costs for SwitchX aren't published.
Does SwitchX need a green screen?
No. Auto mode tracks the subject from ordinary footage, and Upload mode accepts external mattes if you want frame-accurate control.
What resolution does SwitchX output?
720p or 1080p on Beeble Cloud, with the source clip's frame rate and aspect ratio preserved. There's no 4K SwitchX output as of August 2026.
How is SwitchX different from SwitchLight?
SwitchLight (CVPR 2024) estimates lighting and PBR passes for you to composite manually; SwitchX generates the finished composite itself.
Where can you run Beeble SwitchX?
Beeble SwitchX sits in the video tools of the invideo agent — describe the switch you want ("same take, golden-hour rooftop instead of the office"), attach your footage, and the agent returns the composited shot into your project. You'll find it on invideo's AI models index; on the AI video platform that gives serious creatives every major model in one place, the reference image, the switch, and the final edit can all happen in one thread.
