Hi Christopher
One idea, using the hyperlink property on your Thing Template. As this can be used with the HTML5Video widget, as this property can be bound to the VideoLocation property:
https://marketplace.thingworx.com/tools/html5-video
This requires using an HTTP link, here is an example:
http://clips.vorwaerts-gmbh.de/VfE_html5.mp4
This is an example of storing it in Thing and using it for a Mashup.
