Sorry, our API documentation doesn’t make it clear that video returns base64 encoding, so the easy way to test this is to use the video tag in your html and set the src to base64. Of course, you will need to add the base64 header “data:video/mp4;base64”, as in the following example

<video controls type="video/webm"
src="data:video/mp4;base64,AAAAIGZ0eXBpc29tAAACAGlzb21pc28yYXZjMW1wNDEAAAAIZnJlZQAQM4VtZGF0AAACsQYF//…“ />
