Frequently Asked Questions

PCIe capture card lossless frame grabber with DVI/VGA+S-Video/ composite + audio inputs. DVI2PCIe can capture video from any single or dual-link DVI, unencrypted HDMI video, VGA, or BNC/ component video source at up to 85 FPS. Any resolution up to 2048×2048 (2560×1600 widescreen) is supported.

What PCI interface is needed for DVI2PCIe Pro?

The DVI2PCIe Pro is compatible with PCI Express (PCIe) 1.1 or higher interface.


How can I verify whether my system has PCIe?

Nearly every recently made PC or MAC since 2007 comes with PCI Express support. Please refer to your motherboard specifications to see if it has support for PCIe 1.1.

How many frames per second can DVI2PCIe Pro capture?

It depends on the resolution of your screen, the screen refresh rate, your operating system and the speed of the computer that is acquiring images. Please consult the Specifications for appropriate capture rates.


Does DVI2PCIe Pro reduce the resolution of the images it captures in order to transfer it over the PCIe bus?

No. DVI2PCIe Pro captures and transfers every pixel of the original DVI frame in RGB24 format. DVI2PCIe Pro may optionally perform on-the-fly color-space conversion before transferring the image over PCI Express. In this respect, DVI2PCIe Pro provides better quality than a DVI-to-video converter paired with a Composite or S-Video grabber.

Can DVI2PCIe work on Windows NT, Windows 3.x/95/98/SE/ME?

No. Unfortunately, some of those systems have very poor support or no support at all for PCI Express.

The video mode that I am using is not listed in the list of supported modes for DVI2PCIe Pro. Can DVI2PCIe Pro capture it?

Yes. You may add custom modes through the DVI2PCIe Pro software, available as a free download.

What Linux kernel does DVI2PCIe Pro support?

The Linux drivers are available. Please contact us ahead of purchase if you require a driver compiled for a specific kernel version or kernel setting.

Can DVI2PCIe Pro save captured signals as a movie?

Yes, the DVI2PCIe Pro application has the ability to save captured signals as an AVI file (Windows) or MOV(Mac).

Which codec works best with DVI2PCIe Pro?

The choice of codec and codec settings depend on the requirements for the quality of the AVI or MOV. You may need to try several codecs with different settings to see which codec best fits your task.

Images grabbed from some sources appear to be slightly shifted right or left. How this can be fixed?

DVI2PCIe Pro has an automatic algorithm that crops visible images from the DVI frame. The algorithm may make a mistake, however, and be off by a few pixels. Please refer to Configuring Image Adjustments in section 18 of the Frame Grabber User Guide.

Can I connect two or more DVI2PCIe Pro devices to one computer and capture signals simultaneously? What is the resulting rate of capture for each DVI2PCIe Pro?

Yes you can connect two or more DVI2PCIe Pro devices and capture multiple signals simultaneously. You will need to run the DVI2PCIe Pro application for each DVI2PCIe Pro device attached.

With what software can I interpret the digital signal generated by the DVI2PCIe Pro device?

The DVI2PCIe Pro frame grabber works by emulating a high resolution video camera for Windows. DVI2PCIe Pro is a DirectShow compatible device, which means that virtually any video capture software designed for Windows is compatible with DVI2PCIe Pro. For example, VirtualDUB can be used to record .avi files, Microsoft Media Encoder to record .wmv files, and RealProducer to record .rm files. DVI2PCIe Pro also supports QuickTime in Mac OS X and Video4Linux in Linux operating systems.

Does the frame compression on DVI2PCIe Pro hamper the quality of the output?

No. DVI2PCIe Pro devices do not use frame compression, resulting in a high quality of the output.

Is DVI2PCIe Pro software compatible with Mac OS X?

Yes. DVI2PCIe Pro is compatible with Mac OS X 10.4 and up. Drivers and software can be downloaded from DVI2PCIe Pro download page.

Can I capture HDMI with DVI2PCIe Pro?

Yes. You may capture the video only from an HDMI signal using DVI2PCIe Pro using a HDMI-DVI converter cable, included in the box. Note that DVI2PCIe Pro cannot capture a protected or encrypted HDMI signal.

Does DVI2PCIe Pro support other inputs such as BNC/component, DisplayPort and Thunderbolt?

Yes. DVI2PCIe Pro can capture unencrypted images and video from BNC/component, DisplayPort, Mini DisplayPort, and Thunderbolt outputs. In order to capture video from these formats, the appropriate converter cable needs to be purchased separately. Epiphan does not guarantee the result when using 3rd party cables.

What is the difference between DVI2PCIe and DVI2PCIe Pro?

DVI2PCIe Pro supports higher VGA and DVI resolutions, DVI-Dual Link, comes with 2nd SD Video port, and professional grade audio inputs.
