2017-04-02 07:36:41 -0600	commented answer	VideoWriter fps parameter @berak thanks for the reply. Is it possible to provide some clarifications on what is happening on the saved video when the parameter `fps` is different to the real fps? Is there an up-sampling or down-sampling procedure? In other words, how the saved frames are distributed? Thanks again.
2017-03-24 04:23:14 -0600	asked a question	VideoWriter fps parameter Through the `VideoWriter` the incoming webcam stream is stored in uncompressed form in a `.avi`. The opencv `VideoWriter` has an `fps` parameter that should be set in the initialization of the object so as to proceed with the video writing. However, the incoming stream may have an `fps` lower of higher to that defined in the parameter. Also the real fps of the incoming stream may be not constant. My question is how the data are stored into the uncompressed `.avi` in accordance to the real `fps`? Is there an up sampling or downsampling so as to meet the `VideoWriter` fps? I couldnt found a documentation for that explanations or other ones that I could not imagine right now. Thanks.
