New pilot and flew my first flights out of eyesight. 1/2 mile then 1 mile. it was pretty awesome and in an urban area. I recorded video in the HD mode that is just below 4k and followed the recommended camera settings from Tom Tech guy. NSTC, etc. When I play back the video on my PC, just a blank screen. The first frame is fine before hitting play but when i play, nothing. White screen in VLC, crash PC in Windows 10 video player, nothing in Windows Movie Maker and nothing in Windows Media player. Is this because my graphics card cannot handle the resolution? settings are wrong? The video file sizes and what I would expect. Any ideas greatly appreciated. Yeah, I admit it was a bit of a pucker flight but super impressed with the response and reliability.
