Matrox CompressHD Technical Specifications

MAX H.264 Encoding Acceleration
Resolutions Even frame sizes from 64 x 64 to 1920 x 1080
Bit rates 100 Kb/s to 50 Mb/s
Frame rates 15, 23.98, 24, 25, 29.97, 30, 50, 59.94, and 60 frames per second
Encoding profiles Baseline (CAVLC) and main (CABAC) profiles
Encoding controls
  • 2.0, 3.0, 3.1, 4.0, 4.1, and 4.2 level support
  • GOP structure
  • Constant bit rate (bit rate remains stable, quality varies depending on complexity of each frame)
  • Constant quality (each video frame is analyzed to deliver the targeted quality, bit rate varies while keeping the lowest possible bit rate)
  • Variable bit rate (squeezes out the highest possible quality at the average target bit rate )
  • Noise filtering (saves bits by reducing high frequencies in the video)
  • De-interlacing (ensures high-quality encodes of interlaced SD and 1080i source material)
  • Data rate slider (produces smoother or more abrupt transitions)
  • Sample rate monitoring (verifies compliance with targeted data rate)
  • Scene detection (provides multi-pass quality in a single pass with Apple Compressor)
Scaling
Dedicated hardware scaler Multi-tap 10-bit realtime processing
