Yes and No. Videos cannot be added to an image field, and there is no video field type available for SmartCapture or SmartInspect.
However, the URL field can be used to link to any external resource. A video clip, uploaded to a video hosting site such as YouTube or Vimeo, could be linked within a URL field. This would allow a SmartView user to navigate from the plan to the linked video and view the content.
To have a URL field added to your form, you can submit a request through the APX Help Center.
