For those looking for a more customized solution, you can upload your own self-hosted videos using the nifty Video Post Format right from within your dashboard. Each video will be fully responsive and look great on any device!
Simply create a post like you always would, select Video in the format box, then enter the destination of your video file (MP4, M4V, OGV) right below the main content area. In addition you can select the desired aspect ratio for optimum viewing.
Like above, you can optionally set a featured image that will show before the video is played.
