Seems like a standard file
naming convention of the camera recording the video.
Etsy was originally for people who made stuff and to enable them to sell it. It's apparently been inundated with Chinese shite, likely drowning out the original target sellers. There were also reports of Etsy hanging on to sellers funds for 45 days I think it was, putting sellers livliehoods at risk by not letting them have the funds in a timely fashion (and no doubt earning interest for Etsy).
