• On‑board rotary switch to assign card number (16 positions, 0 to F)
• Device tree shows “01: Pro Capture AIO” when selector is set to 1, and so on
• Video and audio device names include the assigned card number

Multiple Capture Streams

• Unlimited capture streams per input channel
• Independent settings for cropping, aspect ratio, color format, resolution, frame rate, deinterlacing, and color correction for each stream

Ultra‑Low Latency

• Latency of only 64 video lines
• Partial notification mode in the SDK

Synchronization & Timestamps

• High‑resolution hardware clock (100 ns)
• Timestamps on each audio frame (192 samples) and video frame, based on the hardware clock
• Clock synchronization between cards via SDK

SG‑DMA Video Output

• Automatic detection of tiled surfaces on Intel GPUs
• DirectGMA support for AMD chipsets
• GPUDirect support for NVIDIA chipsets
• DMA bandwidth of 400 MB/s per channel on PCIe 2.0 and 200 MB/s on PCIe 1.0

SDK

• Pro Capture SDK for DirectShow (Windows) – easy integration
• Pro Capture SDK for DirectKS (Windows) – maximum flexibility and performance

Windows Driver Settings

• All options controllable via registry keys at global, product, or device level
• Ability to customize video, audio, and crossbar filter names via registry

Firmware Update

• Multiple cards can be updated simultaneously
• “Hot” update without shutting down the system if the card is not in use
• If an update is interrupted by power or system failure, the card automatically recovers the initial version (available from firmware 1.21)
