If you can’t find the settings, then these settings will most likely work well for you. The key bit is the aspect ratio (that’s the ratio between width and height). Here we have 16:9, (1280:720), so you just need to make your photo or video that size and you’re good to go.
All that said, you can just upload a picture and it will do the magic for you, but you might lose the edges and that might be important.
Question: Image or video?
Well either work. It depends on how much you want to stand out, what you can do yourself, what time you have and so on, but I favour the video personally as it’s more eye catching and not yet overdone. This article though, is just about the image option
Question: How do I make an image background?
Quite simple really – you could do it in Powerpoint and make sure your slide is set up as “HD” (go to design tab, click on slide size), or use any imaging software you have, to create this space. You can add images that you have or can access from the internet (checking for copyright) and add your logo and away you go. (I’ve heard sites like canva are very good)
Question: How do I space out the image elements?
Usually you’ll be sitting in the middle, so make sure your background has important imagery and messaging to the sides (or to one side if you want to sit off centre), and think of splitting your screen in three. It doesn’t matter if you overlap your logo/message a bit as you’ll be moving around, especially if you place your logo at the top.
