Editing video start/stop times in Rise360 not working with TED Talks and VIMEO

Hi, I was able to tweak an embed code to make it work for YouTube but not for a TED Talk and VIMEO video.

Trying to incorporate this video and cut it at 3:30 but nothing I've tried has worked. https://www.ted.com/talks/david_r_williams_how_racism_makes_us_sick

This is what I thought the code should be

<div style="max-width:854px"><div style="position:relative;height:0;padding-bottom:56.25%"><iframe src="https://embed.ted.com/talks/lang/en/david_r_williams_how_racism_makes_us_sick?start=0&end=210" width="854" height="480" style="position:absolute;left:0;top:0;width:100%;height:100%" frameborder="0" scrolling="no" allowfullscreen></iframe></div></div>

And this VIMEO.

I appreciate any help I can get!
