The higher the resolution, the harder the editing is... editing 4K on a machine not specifically built to handle that will make someone never want to edit again.
Amen, I don't care how much of a smokin' computer you think you have. 2.7K and 4K video will bring it to it's knees!! Same goes on YouTube video. I have just shifted to uploading 1080p to YouTube and they are some big files. I have a 50Mb Internet pipe coming into my home, but that doesn't mean I can upload at that rate. Dump a 5Gb video up to YouTube and you will be pouring a cocktail. Upload time and processing time is healthy. And if you are lucky, the music police won't reject it due to copyright music usage! That's frustrating to have to start all over.
I have gotten enough hits on my videos now that YouTube is constantly offering to monetize my videos. They are also allowing more and more copyright music if you agree to ads. So I always play the game of using popular music in lieu of ads. Sorry, I digress. It's a pet peeve of mine.
I knew my latest video may get some hits nationally, so I shot it at a higher resolution and uploaded at a higher resolution, and used popular music to help captivate more viewers. But it took 3 edits and 3 uploads before I got one to go through. It was worth it, though.
I think you will find, when your videos get views on YouTube more than the 40-50 friends and family it will become addicting. You want to do the little things that will make more people want to share it. Better shots, better edits, less personalization, cooler music, better locations or topics etc.
Pop this one up to 1080p and full screen. Runners in the Fargo Marathon starting tagging family and friends when they could start seeing faces.
(note when the video is slowed down to 50% speed, the quality remains since it was shot at 60fps)
