Hey Guys,

I edited my first cinematic mavic mini footage today. I decided to upload to Youtube in 4k. There seems to be a difference in quality between 2.7k and 4k when uploaded. Did DJI give us a drone that is capable of 4k without actually telling us? anyway, let me know what you guys think!

The way I understand it, Youtube allows ~10Mbps for 4K using their VP9 compression codec whereas they limit 1080p to ~2Mbps.

So yes, we're upscaling our footage by 48% to get from 2.7K to 4K, but then there's less compression on the youtube end so it's less blocky during fast motion and retains better colours.

Youtube processes video above a certain resolution in a 'better' way.
1080p videos will often seem a touch blocky in dark areas after uploading.
If you can do it with your software, try a render setting at 1440p with highish bitrate and upload that, this seems a particularly sweet spot for viewing at their 1080p and you can upscale or downscale to that [1440] size with little difference in the results.
The great majority of YT views are at 1080p even on screens and connections which can go higher.

Nice, smooth video - esp. like the close flying around the trees.

Why is the video blurry around the edge? I tried every resolution (including the highest HD resolution) but they are all blurry around the edges. Is this an artifact from the upscaling? Which aircraft is this?
