Embedding Video from VHX.tv

I’m trying to make this video responsive on our site, and tried your plugin, but can’t seem to make it work. Here’s the full embed code:

<iframe src=”https://embed.vhx.tv/packages/374?title=0 buy_btn=0″ width=”650″ height=”352″ frameborder=”0″ allowfullscreen=”allowfullscreen”></iframe>

Here’s what I tried to use based on “Responsive Video” settings instructions:

[video align="right" aspect_ratio="16:9" width="90" autoplay="0"]https://embed.vhx.tv/packages/374[/video]

Please advise.
Thanks! Chris
