How to choose a DVI capture card

Users need to capture video from devices for multiple different reasons. The types of video are limitless. From security (e.g. CCTV, IP network) to medicine (e.g. ultrasound and X-Ray imagery), education, engineering, simulation and control rooms.

As long as a device has a DVI or VGA output port (or an output adapter to DVI or VGA), the output signal can be captured by a DVI or VGA capture card or video grabber. Once the signal, or stream, is captured you can save the data to a computer to archive it, print the captured images, stream the data to the Internet or upload it on an FTP server to make it accessible for remote users.

Many different types of capture cards and video grabbers exist. For the widest possible range of uses from a single device, Epiphan recommends selecting capture devices with DVI inputs that can accept DVI, HDMI and VGA signals.

DVI capture cards

DVI-based capture solutions are available in internal (PCIe) and external (USB 3.0, USB 2, Ethernet, or Thunderbolt) form factors. When determining which capture device to purchase, the first question to answer is whether or not you’ll want an internal or external device. From there, explore the versatility of the devices, capture quality, and capture speed (fps).

Internal DVI Capture Cards

Depending on your requirements the internal cards may suit your needs well. For instance, if you always use the same work-station and usually work in the same environment, Epiphan’s DVI2PCIe or DVI2PCIe Duo cards are a fantastic choice. With lossless capture at up to 80 fps, these capture cards are installed inside your Windows, Linux or Mac computer. You can immediately begin to capture dual-link DVI (single-lik for DVI2PCIe), VGA, BNC/component or unencrypted HDMI video signals. You can capture full HD at a capture rate of 60 frames per second for 1080p video. These cards are compatible with all popular OSes and fit into a x1, x4, x8 or x16 PCIe 1.x slot

External USB – Vido Grabber – High Resolution and Portability

Sometimes, portability is what you need. This may be due to size constraints of the capturing computer (i.e. a laptop can’t fit a PCIe capture care) or may be because multiple capture computers share a single capture device, or for other reasons. If you work with high precision video sources and need to get very high quality image capture from a portable device, look at the external video grabbers provided by Epiphan Systems. We have solutions that support resolutions up to 2048×2048 and frame rates up to 60 fps.

The most versatile and portable grabber for video capture is DVI2USB 3.0. DVI2USB 3.0 is used to capture video from VGA and single-link DVI and video with audio HDMI over USB 3.0. It is also backwards compatible with USB 2.

For dual-link DVI, DVI2USB Duo captures images and video with resolutions up to 2048×2048 (or 2560 x 1600, widescreen).

Both these video grabbers are compatible with Windows, Mac OS X and Linux.

External Ethernet – Video Grabber – High Resolution and Portability

If you need to stream the captured data directly via the Ethernet/IP network connection to a capture computer, consider choosing VGA2Ethernet. Unlike the USB connected frame grabbers, this device sends captured DVI/VGA data directly Ethernet port on the capture computer. VGA2Ethernet supports VGA, DVI and HDMI video sources and resolution of up to 1920×1200.
