3DGS/4DGS UE5 Plugin

3D & 4D Gaussian splatting, native in Unreal Engine 5

Our UE5 plugin imports .ply and .splat captures from Luma AI, Postshot and Polycam, renders millions of splats with LOD, and plays 4D dynamic sequences at runtime. Free with watermark — separate from API credits.

The API

Every API your media pipeline needs

Ten specialized models, one consistent API: object-storage in, object-storage out, async jobs, webhooks and Postman collections for every endpoint.

SDR2HDR API

Convert SDR video to HDR with restored brightness, gamut and detail.

Subtitle Eraser API

Remove hardcoded subtitles cleanly for localization and short-drama export.

Subtitle Extractor API

Extract on-screen text and spoken dialogue with frame-accurate timestamps.

Vocal Separator API

Isolate vocals or instrumentals from speech and music mixes.

H.264 Encoding API

Perceptual, cost-efficient encoding tuned for real viewing quality.

H.265/HEVC Encoding API

Next-gen efficiency with the same neural perceptual engine.

Super Resolution API

AI upscaling that recovers real detail, not just sharpening.

Frame Interpolation API

Smooth motion with AI frame generation — 24 to 60 fps.

Source Separation API

Separate any mix into clean stems — including environmental sound.

AI Mixing API

Auto-mix stems to surround and object-based immersive audio.

Try it in Postman first

Every API ships with a Postman collection — sample requests prefilled, environment setup in one click, no code required.

Use cases

Where teams use mlslabs

Short-drama & streaming export

Extract, translate, erase, remaster and encode — one pipeline that turns a raw episode into market-ready masters in every region.

Video

Music production

Stems from any song, clean vocal tracks, auto-balanced mixes, and spatial masters — the whole production chain as APIs.

Audio

Immersive audio

Stereo in, object-based immersive out: separate the sources, mix them into space, deliver 5.1, 7.1.2 or Atmos-ready masters.
