NVIDIA Video Effects

AI background removal and blur, relighting, webcam denoise, upscaling, enhance and frame generation on NVIDIA RTX graphics.

NVIDIA Video Effects bring AI effects to your cameras and screen captures, running on the Tensor Cores of your NVIDIA RTX graphics card. They're free, built into DualStream, and every effect is off until you turn it on.

What You Need

  • An NVIDIA RTX graphics card (RTX 20, 30, 40 or 50 series), and it must be the card DualStream renders on.
  • NVIDIA driver 570.65 or newer. If your driver is older, DualStream tells you which version to install.
  • A one-time download. The first time you open the effects, DualStream offers the download and shows its size. It pauses while you're live or offline and picks up where it left off.

On other graphics cards the NVIDIA sections don't appear.

Where to Find Them

Select a layer, then open the Inspector Panel → Effects tab. Each NVIDIA effect has its own section with an on/off switch.

Every Canvas, Its Own Look

Each effect is set per canvas. Your Desktop canvas can blur your background while Mobile removes it completely, or light you differently on each. When both canvases ask for the same work, DualStream does it once and shares it.

Your NVIDIA effects save with your scenes, scene packs and recipes.

Background Removal

Removes the room behind you without a green screen.

  • Background: Remove clears it, Blur keeps it softly out of focus.
  • Blur Strength: how soft the blurred background looks.
  • Detection Model: Quality or Performance, each also offered with your chair counted as background.

Webcam Denoise

Cleans up grain from a camera in low light. Choose Light or Strong.

Lighting

Relights you as if you were somewhere else.

  • Preset: Studio, Warm Studio, Loft, Sunset, Neon or Daylight.
  • Rotation: turns the lighting around you, from -180 to 180 degrees.
  • Intensity: how strongly the new lighting shows.
  • Behind You: Your Background keeps your room, The Lighting's Room shows the place the lighting comes from.

Upscaling

Upscales a source to the size your canvas shows it at, so a smaller camera or window stays sharp when you make it big.

  • Method: AI Super Resolution or Fast.
  • Quality (AI Super Resolution): Performance or Best quality.
  • Sharpness (Fast): how much sharpening the upscale adds.

Upscaling runs only when the canvas draws a source larger than its own size.

Enhance

Cleans up a source at its own size, before any upscaling.

  • Type: Sharpen, Denoise or Detail.
  • Strength: Low, Medium, High or Ultra.

Frame Generation

Makes a new frame between each two a source sends, so a 30 fps camera or game capture moves smoothly on a 60 fps canvas.

  • Quality: Low, Medium or High.

Frame Generation adds one canvas frame of delay. It steps in when a source runs well under your canvas frame rate, like a 30 fps camera on a 60 fps canvas.

Control Them From Anywhere

Stream Deck effect keys and AI assistants connected to DualStream can switch NVIDIA effects on and off by name: Background Removal, Webcam Denoise, Lighting, Upscaling, Enhance and Frame Generation. An effect shows up in the Stream Deck list once you've turned it on in DualStream at least once. See Stream Deck.

FAQ

Do NVIDIA Video Effects cost extra?

No. They're included for everyone with a supported NVIDIA RTX graphics card.

Can I use them with a green screen or chroma key?

Yes, but you rarely need to. Background Removal works without a green screen.

Does upscaling affect what Relay sends?

Upscaling changes how a source looks inside your canvas. Relay still sends your canvas as it is, at the largest size each platform accepts.
