Description
Product Overview
The Magewell USB Capture SDI 4K Plus is a one-channel 4K SDI capture device designed for broadcast, live production, streaming, recording, and professional video workflows. It accepts and loops through SD, HD, 3G, 2K, and 6G-SDI sources, with 6G-SDI supporting video up to 4096×2160 30fps 4:2:2 10-bit. Native 4K USB capture, high-frame-rate HD modes, analog audio connectivity, and hardware video processing provide flexible integration with production computers.
Native 4K30 SDI USB Capture
Capture video at resolutions up to 4096×2160 through the USB interface. Explicit 4K output modes include 4096×2160 and 3840×2160 at frame rates up to 30fps for professional recording, streaming, ingest, and production workflows.
6G-SDI Input and Loop-Through
Professional BNC connectivity supports SD, HD, 3G, and 6G-SDI standards with a dedicated loop-through output. Maximum 6G 4K input and loop-through is 4096×2160 30fps 4:2:2 10-bit.
1080p90 High-Frame-Rate Capture
For motion-intensive workflows, explicit output modes include 1920×1080 and 1280×720 at frame rates up to 90fps. Magewell also specifies overall capture capability up to 120fps depending on resolution and available USB bandwidth.
High-Bandwidth Hardware Video Processing
An approximately 640M-pixel-per-second processing pipeline handles cropping, up and down scaling, deinterlacing, aspect-ratio conversion, color-format conversion, frame-rate conversion, flipping, and mirroring in hardware.
Embedded and Analog Audio Support
SDI input supports up to eight channels of embedded audio. A 3.5 mm Line In provides analog audio input, while the Line Out connection can extract audio from the SDI source. USB capture supports up to two audio channels at 48 kHz.
Broad Software and OS Compatibility
Use the device with Windows, Linux, macOS, and Chrome OS. Magewell lists OBS Studio, Zoom Rooms, Microsoft Teams, VLC, XSplit, QuickTime Player, and other compatible capture and streaming applications.
