Conclusion

The Epiphan DVI2PCIe card is not just a good image/video capture device but perhaps the best internal frame grabber for professional applications. It offers three important advantages compared to its competitors.

First of all, the DVI2PCIe card ensures immaculate image quality. Thanks to native support for digital interfaces and the lack of digital-to-analog conversions, the resulting image is identical to the original. And even if the DVI2PCIe works with an analog video source, the capture quality is very high. The card’s analog section doesn’t worsen the quality much, its ADC being among the best solutions of its kind.

Second, the card features impressively high performance. Thanks to the high-speed PCI Express x4 bus, it can capture video without any loss (i.e. at the typical refresh rate of a computer monitor) at resolutions up to 1600x900 pixels. And the image quality remains high even at higher resolutions. For example, the Epiphan DVI2PCIe can capture Full-HD video at 40 fps, which is a very good result. The frame rate can be even higher, if you don't mind compromising a little on quality.

And third, the Epiphan DVI2PCIe is flexible in terms of connectivity options. Although it only has one DVI connector, it supports various video sources via appropriate adapters: both digital (DVI, HDMI, DisplayPort) and analog (D-Sub, composite, component).

There is only one application where the Epiphan DVI2PCIe isn’t perfect. It’s when you use it for video editing. The fact is it cannot capture audio via HDMI or DisplayPort and doesn't have video outputs that would allow watching the resulting video on a dedicated monitor or TV-set. The card is not actually positioned for such applications, though.

The price of this device, which is about $1000, isn’t affordable but it is a strictly professional product with advanced capabilities. Considering the lack of any competitors with similar specs, the Epiphan DVI2PCIe doesn’t seem to be overpriced.
