How to set video in Template Cashemir

I’d like to set a video on top like at “home personal video” page but i can’t see any option to set or change.
In “Load templates” there is no option in “Section element templates”, only “Testimonial with photo” is available.
In slider i tried to insert an image in html code (above “We are cashemir”). In page view the image is already streched to fullscreen. How can I disable that manipulation?

Who can help?

Many thanks!

Your best of asking the author directly.

I’ve got a subscription of Envato Elements and need help to use what i bought. I dont think i have to tell the author i love his work every time if somethings goes wrong. Its very difficult to find help at envato!
