This whiteboard animation is a great example of how a video can use simple imagery and and carefully crafted voiceover to target their audience. This company links individuals who need a medical opinion with Doctors who have the expertise to help without getting bogged down by paperwork.
What is most effective about this explainer video in particular is how it uses clear visuals to support a well-crafted message. This allows viewers to focus on the company's service, rather than distracting them from it with too many complex images. That ensures people will be asking about how they can join the service rather than why there was a cartoon cat doing a brain scan. The script also expertly anticipates the concerns of their audience and addresses them organically while still leaving them wanting to know more by the video's end.
