hi, I've been recording in 4k...but is it worth it? I don't even have a way of viewing 4k, my laptop is quite good, but is 1080p, tv too! and, Most probably most other people don't have 4k pc's or tv's...so should I stick to good old 1080p? If so, what is the recommended frame rate? 120fps seems excessive as I'm not really needing slowmo at the moment... thanks guys!
