8GB of RAM is unusable for even basic 1080p video editing. I would think a Macbook air's use case included that, because there are a wide range of $700 Windows laptops that will provide the 16GB minus the extortionate markup.
A little while ago I asked on HN if an M1 with 8GB of ram is enough for major 4k editing in FCPX and multiple people chimed in to say they're using that exact setup and it's smooth as butter...
