This.StartPosition = FormStartPosition.Manual This.FormBorderStyle = FormBorderStyle.None This is basically the final piece in the puzzle, from the solution to a similar issue posted here: Draw semi transparent overlay image all over the windows form having some controls using System I created a Form that sits on top of the form playing the video, and set it's color transparency key to white, and set the window background to white.Īfter doing that, you can overlay things like picture boxes that have a Png with a partly transparent background and it will render as expected. For anyone else looking to do this, here is the solution.
