    I want to learn how I can mask video to any shape I desire, how do I mask video and have the video have an alpha channel for when I export?

    To mask an object in a video clip you have to use the bezier tool. You will then need to track the object so the mask will stay over the object. You may also need to adjust the mask over time to keep the object hidden. Once you are satisfied with the mask, you would export the sequence as an Animation. The settings in the animation export will allow the alpha channel to be maintained.
