According to Nikon's website, it is limited to 3 minutes, and the PDF says that the 25:59 limit is recorded to separate files. As much as I want to be a Nikon fan again, this camera just isn't relevant for video next to competition from Samsung, Sony, Panasonic, and BlackMagic. I'm sure the photos from it are amazing, but 3 minutes of 8-bit 4K is not enough to be considered a serious video cam.
When I was in theater classes in school, our instructor had a rule: "When you walk in the door, you leave the outside world outside." It helped me learn how to focus on something, and tune out anything else that might be happening in my life. There are exceptions to this, however. Sometimes you need to let stuff in, even painful things. Do this if allowing those emotions to influence you will help the viewer to adopt the proper perspective for your art. Good actors do this well, and as filmmakers, we should learn to do the same thing.
I didn't see him draw this parallel, but I always thought green screens were brighter on camera because most cameras have twice as many green pixels as the other colors, and use the green channel for luminance. Another reason to use scopes (not eyeballs) when it come stop measuring luminance for a key.
When I use this technique, I try to make the cuts as smooth as possible by doing exactly what you said. Using an atmos track, or simply placing incredibly quick fades to even out some rough edges. That being said, it's really hard to do if the inflection in the voice of the subject doesn't lend itself to pauses. Sometimes it's hard to walk the line between bringing out the best of each subject, and manipulating the footage to make a better product.
As much as I'm a fan of making drone's accessible, this sales pitch is trying to make it seem like flying one can be idiot-proof. Drones operate in a three-dimensional space that is occupied by many other things. Sometimes flying isn't as simple as drawing a line and picking an altitude, and to think otherwise can lead to property damage or serious injury. As a drone operator, I'm all in favor of the tech getting better, but I also want everything flying to be operated manually, so that there is always a person who can be held responsible for anything that happens.
