This means that the codecs recognized by Windows are recognized by NI Vision products as well. Through AVI2, on Windows any codec that is compatible with Microsoft's Video Compression Manager is available to the user. Built-In Codecs and Codec Support Through Microsoft's Video Compression Manager This section describes new features available through AVI2, including broadened codec availability, expanded Windows 64-bit compatibility, and Real-Time (RT) target support. An overview of Vision Development Module is available at the following link: Products and Services: NI Vision Development Module. The guaranteed presence of these codecs allows for portability of AVI files built from AVI2 functions.ĪVI2 is installed starting with Vision Development Module 2012 SP1 and Vision Acquisition Software February 2013. Finally, on both Windows machines and compatible Real-Time (RT) targets, NI provides the following four codecs: FF Video Codec 1, Motion JPEG, Y800 Uncompressed, and YUV 4:2:0 Planar.

Because the AVI2 implementation uses Microsoft's Video Compression Manager, many of these codecs are now accessible on Windows 64-bit machines. In addition, previously many codecs could not be used on Windows 64-bit machines. On Windows the user now has access to any codec on the system that is compatible with Microsoft's Video Compression Manager. NI's AVI2 implementation recognizes codecs instead of filters. They are now labeled 'AVI2' to distinguish from older AVI functions and VIs. As a result of this new implementation, the functions and VIs for AVI have been renamed. Through NI Vision products, a user is able to create and read AVI files, and that functionality has been expanded to support more codecs and more devices. The user who builds the AVI file can choose which codec to apply depending on what the intended use of the video is.

These codecs translate the video data to compress it and optimize it for certain uses. With AVI, video data can be encoded or decoded with any number of codecs. AVI (Audio Video Interleave) is a widely-used multimedia container format commonly used to package videos.
