Hey again all... noob here with another dumb question This is my first action camera so I'm playing with free video editors. Too cheap to buy one when I don't know what I'm doing yet. I think my little Dell laptop may not have enough GPU juice to properly run a 4K video. (By the way, I stuck a brand new Sandisk Ultra 128Gb C10 Micro XC card in the camera and it must have automatically formatted to exFAT. At least that's what Windows says it is. I left it alone. It's actually only 119Gb formatted) So I took a short 26 second video straight out of the box. I copied it onto my laptop and it looks like it was recorded in 4K 30fps. I'm still trying to get used to the cameras controls and settings. I opened the video with Windows Movie Maker and it won't even show up... it just plays but as a black screen. VLC Player won't even touch it. So I opened it in VSDC Free Video Editor and at least now I can see the video and hear the audio. Unfortunately it's super choppy and just chops along every 1 second until it's done. So I converted it to 1080p and it plays just fine. Does this sound like a lame GPU issue (and time to buy a better laptop), or is there something I'm missing? I can download any MP4 video off the interwebs and they'll play fine, but they're all 720 or 1080p. I suppose I can look around for a 4K video and download it to test my laptops capabilities. I might throw the video on my sons major gaming machine and see if it plays fine in 4K. I'd hate to record all my videos in 1080p if I have 4K available. Thanks EDIT: Thinking about it now, I don't have a way to watch a 4K video anyways. None of my TV's are 4K, and 90% of people can't watch 4K either... all I'm doing are regular boring videos for YouTube\Instagram so 1080p is fine. I'll live with it.
