Design help CMS

I am trying to create a video CMS with Webflow that will allow me to create a MRSS feed of all the videos in my collection. I only need to parse the elements described in this spec. Based on the MRSS 1.5. specifications, I can use this feed to manage content on OTT devices. Here is link to the MRSS specs.
