Hi @creedon! Sorry for bumping such an old thread; I'm looking to do the same as the others in here, but I'm going to try to buck the trend of this topic so far.
My site is [SITE URL REMOVED] and I've created two identical homepage header sections, except one has a landscape video (for desktop) and one has a portrait video (for mobile). Hopefully this is what you need to be able to help, or anyone else!
Will the code affect my ability to be able to change the videos themselves in the future?
Thanks for your time.
