Note This VI is not supported on NI CVS-1450 Series devices (NI 1454, NI 1455, NI 1456) or NI 17xx Smart Cameras (NI 1722, NI 1742, NI 1744, NI 1762, NI 1764). |

AVI Path is the complete pathname, including drive, directory, and filename, for the AVI file. This path can be supplied by either the user or the File Dialog VI from LabVIEW.

Frames Per Second is the number of frames per second at which to play the AVI.

Codec is the name of the codec used to write the frames to the AVI file. Call the IMAQ AVI2 Get Codec Names VI to enumerate the list of codes that are compatible with the images you want to save in the AVI. |

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

Quality is the relative quality, from 0 to 1000, to use with the codec. Not all codecs support using different qualities. This parameter is only available for native Windows codes and not for codecs labelled (NI Vision). |

AVI Refnum is a reference to the AVI file created. |

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
