Using Hardware Scaling and Cropping Features
Configure hardware-based video scaling, cropping, and aspect ratio conversion for optimal capture quality.
The Solution
Magewell's FPGA handles scaling and cropping in hardware, reducing CPU load. Configure via USB Capture Utility for resolution conversion without quality loss.
Step-by-Step Instructions
Open USB Capture Utility > Video Settings
Enable Hardware Scaling to convert source resolution to desired output
Set output resolution: Common options include 1920x1080, 1280x720, 3840x2160
Configure Cropping: Remove unwanted borders or letterboxing
Aspect Ratio Conversion: 4:3 to 16:9 with letterboxing or stretching
Set Deinterlacing mode for interlaced sources (Bob, Weave, or Blend)
Apply changes and verify output in capture software
Hardware processing uses zero CPU - all handled by onboard FPGA
Pro Tips
- Hardware scaling is lossless and uses zero CPU
- Crop black bars from letterboxed sources for clean output
- Downscale 4K to 1080p in hardware for CPU-efficient streaming
- Deinterlacing in hardware produces better results than software
