Tutorials. How to Capture High Quality Industrial Video
This article will explain how to capture high quality industrial video from VGA source using a DV2PCIe frame grabber. DVI2PCIe is an internal frame grabber - capture card installed in a PCIe slot of your workstation. This solution ranks among the professional video capture cards and is ideal for industrial video capture. The DVI2PCIe card can capture display and camera with video output such as : DVI, VGA, HDMI, RGB, Component, Display Port, Mini Display Port.
Capture Hardware Required
You will need the following hardware before you start:
A Capture Computer with a PCIe slot to host the DVI2PCIe card
In this example the Capture Computer will be a PC. Epiphan frame grabbers and associated drivers and software are also available for MAC and Linux. The PC is used to record video content, monitor and direct the recording process via the Epiphan Capture Tool interface. 3rd party tools can also be used to capture, record and stream video captured by DVI2PCIe.
A DVI2PCIe card is installed in one the PC’s PCIe slots. It captures VGA, DVI, HDMI video signal from an external source and transfers the images to the software applications via the PCIe bus.
DVI, HDMI, VGA Video Source
A video source that will be captured and recorded using DVI2PCIe and the capture tool.
DVI, VGA. HDMI, RGB Cables and Adapters
The DVI2PCIe card has a DVI input. This common DVI connector supports multiple video sources with the use of adapters and cables. The DVI2PCIe card ships with DVI, VGA to DVI and HDMI to DVI cables or adapters. In this example A VGA cable connects a VGA output to the DVI port of the DVI2PCIe card.
Once you have installed the DVI2PCIe card into an open slot of the Capture Computer, proceed with the following instructions
Step 1: Download DVI2PCIe application and drivers
Download DVI2PCIe application and drivers from the Epiphan Systems’ web site.
1. Browse to support page

11. Now you are ready to start the installation. Click “Next” and continue with the installation
Step 2: Connect and switch on hardware
Now you need to connect the PCIe frame grabber hardware to your video source.
1. Use the VGA to DVI cable to connect your VGA source to the DVI In port of the card. IF you want to capture DVI or HDMI or other video types, use the appropriate adapters or cables
2. Power up both the computer and the VGA source. Your PC detects the installed card.
3. If this is the first time install the Start the New Hardware Wizard may appear. The software is installed automatically.
4. You can change the video sources and/or cables to experiment capturing various display and camera sources
Step 3: Industrial Video Capture
The following steps will guide you through the process of configuring various recording options
1. Click on Start>All Programs>VGA2USB. The frame grabber software starts.
2. Select “Options” from the “Tools” menu in the VGA2USB application. Select the “Recording” tab.
3. Now specify that you are capturing video signal: set “Record as” to “Video” and click the “Select Codec…” button. For this example, Epiphan recommends using ffvfw MPEG-4 Codec for signal capture.
4. Now start video on your VGA video source that you want to capture. The Epiphan Capture Tool will automatically detect video settings and then display the captured image. The top of the window will identify the Frame Grabber card installed and various parameters of the video source being captured. (see below )
5. Click the “Record” button.
6. Select the location for the recorded video file on your PC and click “Save”. The VGA signal capture recording will not start unless you click “Save”.
7. To stop recording, click the “Record” button again.
