Very clever - you got skills son!! Gif animation or a series of stills (as of August 2017) are the best way to show your process on Steemit without using an outside video host. Another way to do it is to make a video upload to your own youtube channel and embed your youtube video here. That seems to work well if you don't mind a connection linking to your youtube channel. Anyone that clicks on the youtube logo in your video will be taken to your youtube channel. Look forward to seeing more from you!
