Genki ShadowCast 3: Turn Your Mirrorless Camera Into a Pro Webcam

Summary:

• Capture card that turns any HDMI camera into a webcam — no manufacturer software required
• 4K at 60fps capture, near-zero latency HDMI passthrough
• Works with DSLRs, mirrorless cameras, camcorders, and action cameras
• iPad becomes a portable monitor via Genki Studio or Camo Studio apps (both free)
• $89.99 — CovertDock 3 companion accessory adds 65W charging and 4K120 HDR for $69.99
• Some cameras need an HDMI mini/micro adapter for compatibility

Purpose

The ShadowCast 3 solves a persistent frustration for photographers who also create video content: camera manufacturers ship unreliable, inconsistent webcam software. The ShadowCast 3 bypasses all of it. It captures HDMI output directly — what the camera sends to an external monitor — and routes it to your computer or iPad as a clean video source at full camera quality.

The secondary use case is equally practical: paired with an iPad running the Genki Studio app, the tablet becomes a portable external monitor — no dedicated hardware monitor required for video creators on the go.

Prerequisites

• A camera with HDMI output (mini or micro HDMI adapters required for cameras without full-size HDMI)
• A USB-C port on your Mac, PC, or iPad
• iPad Pro, iPad Air, or any iPad with USB-C (for the monitor use case)
• Genki Studio or Camo Studio app installed (both free)

Setup Steps

1. Connect the ShadowCast 3 to your camera’s HDMI port using the appropriate cable. If your camera uses micro or mini HDMI, you’ll need an adapter — the device itself uses full HDMI in.

2. Plug the USB-C end into your computer or iPad. The device is bus-powered — no separate power source needed.

3. On a computer, open OBS, Zoom, Teams, or any app that accepts a camera input. The ShadowCast 3 appears as a standard capture device. Select it and your camera feed appears at up to 4K60.

4. On an iPad, download the Genki Studio app (free, App Store). Launch it, select the ShadowCast as input, and your iPad screen becomes a full-resolution live view of your camera — useful as an external monitor during shoots.

5. Adjust your camera settings for clean HDMI output. Most mirrorless cameras need to have their display overlays (menus, focus peaking) disabled for a clean signal. Consult your camera manual for “clean HDMI output” settings.

6. (Optional) Add the CovertDock 3 — Genki’s companion dock adds 4K120 HDR with variable refresh rate, 65W charging, and hub functionality. It’s 1/14 the size of a standard dock and costs $69.99.

The Trap

Manufacturer HDMI quirks. Some cameras lock clean HDMI output behind specific settings, or disable it entirely during charging. A few older cameras cap HDMI output resolution lower than the sensor’s native capture. The ShadowCast 3 faithfully captures whatever signal the camera sends — it can’t override hardware limits. Verify your camera supports clean external HDMI output before purchasing, or check the community compatibility lists at Photo Video Lounge for your specific body.
