SDI2USB 3.0 is compatible with both USB 2.0 and USB 3.0 (SuperSpeed) USB interfaces.

USB 3.0, also known as SuperSpeed, is standard on all computers manufactured after 2011. Please check with your computer or motherboard manufacturer to verify that USB 3.0 is present on your system.

When connected to USB 3.0, SDI2USB 3.0 captures video with resolutions up to 1080p at 60 fps in YUV 4:2:0 color space. Consult the technical specifications for more information about capture rates.

No. SDI2USB 3.0 captures and transfers every pixel as RGB 24-bit. SDI2USB 3.0 performs chroma sub-sampling to a YUV format if selected by the user.

No. Unfortunately, some of those systems have very poor support or no support at all for USB 3.0.

Yes. The SDI2USB 3.0 software has the ability to save captured signals as AVI.

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

Yes. You can connect two or more SDI2USB 3.0 devices and capture multiple signals simultaneously. You will need to run an SDI2USB 3.0 application for each SDI2USB 3.0 device attached. Each SDI2USB 3.0 provides a full frame rate at 60 fps when USB 3.0 controllers support the transmission rate.

The SDI2USB 3.0 frame grabber works by emulating a high resolution video camera for Windows. SDI2USB 3.0 is compatible with DirectShow and virtually any video capture software designed for Windows. For example, VirtualDUB can record .avi files, Microsoft Media Encoder to record .wmv files, and RealProducer to record .rm files. SDI2USB 3.0 also supports Video4Linux in Linux operating systems.

The SDI2USB 3.0 does not use frame compression when connected to a USB 3.0 port and as a result the output is high quality. Compression is used for USB 2.0 connections.
