NI 5431 Composite Video Generator
HL Calculate and Save Video Data
This high-level VI calculates all the video lines corresponding to a specified video format in block mode and saves the composite video data in a binary file (I16) defined by the file path control. The example Basic Create Video File from BMP Image and Save shows how to correctly use this VI.

Digital sync enables the insertion of the four synchronization bits in the four lsbs of the I16 binary data file of the composite signal. | ||||||||||||||

Output binary video file path is the file path for the output binary video data file to be saved. | ||||||||||||||

error in is a cluster that describes the error status before this VI executes. If error in indicates that an error occurred before this VI was called, this VI may choose not to execute its function, but just pass the error through to its error out cluster. If no error has occurred, then this VI executes normally and sets its own corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next. | ||||||||||||||

Video type selects the video format to be used. Use the up and down arrows to select video format. The formats are listed below:

error out is a cluster that describes the error status after this VI executes. If an error occurred before this VI was called, error out is the same as error in. Otherwise, error out shows the error, if any, that occurred in this VI. Use the error handler VIs to look up the error code and to display the corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next. |
