* @brief SaveToVideo_C.c shows how to create a video from a vector of images.
* It relies on information provided in the Enumeration_C , Acquisition_C, and

*
* This example introduces the SpinVideo class, which is used to quickly and
* easily create various types of video files. It demonstrates the creation of
* four types: uncompressed, MJPG, H264 (AVI) and H264 (MP4).
