I've had uploaded videos stay at 1080P for two to three days then show up as 4K. That's seems more of a thing of the past in my case, these days YT seems to get them up at their uploaded resolution pretty quick, 2~3 hrs in a 10min video in 4K/60FPS.I know...it's weird since I only video in 4k. Since YouTube did not render to 4k I checked my settings and they were 4k. For some reason it appears to have gone from 4k to 1080p , then back to 4k. Don't know how that's possible. No one else is involved. No editing program. Straight from the card. I have taken many videos before and since and they are all 4k. Anyone else have this happen??
Gremlins hard at work!
