Lightning Fast H.264 Encoding Card for Professionals
<b>Matrox Compress HD ACADEMIC</b>
Matrox CompressHD implements Matrox MAX technology in an amazingly affordable H.264 accelerator card. It works in systems with or without a video I/O device and extends the life of your current system investment, giving you the power you need to deliver today's premium H.264 formats up to 5 times faster than software alone. This low profile, half-length PCIe x1 card fits into Intel-based Mac Pros and PC workstations and desktop systems. Get yourself a Matrox CompressHD card and deliver your projects in a fraction of the time!
<b>Encoding controls</b>
- 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)
<b>Dedicated hardware scaler</b>
Multi-tap 10-bit realtime processing
