It was initially $2K USD round trip (MIA to MLE via DXB) for us both in economy and then the one way upgrade from Miami to Dubai was an additional $2.5k USD.
What were you looking to learn about the flight from a video? I do have a review on my site which goes into more detail of the food, etc. but it's a flight...there really isn't much going on. Happy to answer any questions you may have.
