RTH Button = Emergency Brake?

Good to know. How much real difference can our eyes perceive from 1080-2.7-4k if just shooting video for fun or to share with friends & family?
Thanks again.

Apparently, if the video is posted on YouTube, none at all!

I have some regular routes that I fly, and I can definitely tell the difference between the settings. Not in the live feed, of course, but in the resulting footage from the card.

The difference between 1080p and 2.7K is obvious. The difference between 2.7K and 4K is a bit more subtle.

At least, to my non-photographer eyes!
