I would like to convert a videofile to a lower quality format. Would VideoWriter() work? Would I use VideoReader() first to point to the correct file, then use VideoReader() to write it in a different quality?

You use VideoWriter to write out to an output video, like in this example:
VideoWriter accepts parameters to change the output file type and other qualify parameters.

See attached demo where I change the pixel resolution of the displayed video and save it as a new, lower resolution video.
