Still relevant because you can extract a frame from the video to create a still image. |

I did a flight today and tried both ways, for me it seems that two fingers are better when I want to turn very slowly, it feels to hold more precise movement and results in smoother video.
My drone has FPV (First Person View) mode, I tried it and the video is very shaky as gimbal is not stabilized in FPV but I can do some fun videos with angled paths :)
Following earlier suggestion I finally realized that gimbal stabilization is so good on the DJI Mini SE that I could take a longer exposure with the drone camera so I ordered an ND32 filter from Amazon to check it out. It won't give me very long shots but maybe some blur when flying fast. |

Given that the controllers often have switches and dials on the shoulder of the controller (and even sometimes buttons on the back), thumbs on sticks is most common so that the fingers can comfortably reach those other controls.

I use my thumbs and sometimes I switch to two fingers. But two fingers IMO are better for FPV drone controllers which are quite different and I'm beginning to study them. |

Thanks, Alessandro. I have also assumed that Tripod was just an old name for Cinematic, it is good to know that this petition might has worked and we could get slower speeds just by updating firmware/software, that will be great! :) I hope DJI does this.
PS I have just finished reading the link properly, I hope DJI does this soon and it is available for all drones.

Not that I'm aware of, at least not at this basic price point. There should be settings in the flight app that allow you to adjust the sensitivity of the sticks to slow down the reaction speeds and smooth out the motion, and if you have a 'cine mode' option then that should also be engaged as that'll have similar effect. Ultimately though, it'll be on you to learn to smoothen out your finger movements and make smaller adjustments. |
Thanks, I have Cinematic mode but it is linear. I guess nothing will replace a lot of practice :) |

The DJI app on your phone/tablet/controller (whichever you use) will display the number of satellites in the upper-right of your screen. I believe the app will warn you (can't remember specifically) if the satellite coverage isn't sufficient. |
That's when you are connected to the drone, UAV Forecast tells me that up to 3 days ahead so I can plan when to fly. |
Oh? Cool. I'm sure different parts of the world have different scenarios; where I fly I've not yet had an issue getting enough satellite coverage (knock on wood!). |

Thanks everyone. I did buy the drone for photography, 3D scanning and video but first I need to get confident with flying it :) I have two apps apart from DJI - UAV Forecast and WindCompass, both very useful for checking the wind and UAV also warns me if there aren't enough satellites. There is also an extremely useful Website for analyzing flights, I find it great for learning:
https://airdata.com/
For smooth video I bought Cinesticks:
https://eu.scottymakesstuff.com/collections/cinesticks/products/cinesticks-sc1-eu
I tried them inside the apartment and they seem to be good, I will try them tomorrow outside. I find rotation the most difficult to master without jerkiness.
There is a Swiss map that specifies "no go" areas for drones, what is difficult to find are the local restrictions. For the Chateau de Chillon the ban on drones was buried in their Website FAQ. It would be great if someone created a map that incorporates all up-to-date restrictions.
In Switzerland you do not need to register a drone that weighs less than 30kg (!) but you must have liability insurance for drones over 500g.
I am planning to get Mini 3 Pro once I am comfortable with using the drone. It has 3-directional obstacle sensing, 48 MP camera and 4K/ 60fps video plus a better controller. I will see what deals will be available on Cyber Monday :) |

That's what I wish more people realized :-) It's not *about* "flying a drone", it's about getting the camera to otherwise inaccessible positions and seeing things from a different-than-usual perspective. This is especially important for elder photographers whose mobility is getting progressively worse. Speaking for myself here, unfortunately :-( |

Key things before drone flying - check your country & local laws, as there could be many requirements around flying them legally (e.g. taking certifications, registering the drone and/or yourself as a pilot, etc), along with researching any temporary or permanent flight restrictions in the areas you're thinking of flying. DJI's apps do a reasonable job in checking some of those for you, but they're not something you should rely on to be legally correct. For example, the app shows that its OK to fly drones in the parts of NYC that aren't near airports but the local city laws now completely ban drone flights, so trusting the app to be right could get you in hot water there!
When actually flying, make sure you keep a safe distance away from people, private property, and any wildlife - that should be common sense tho! The line-of-sight rule varies from place to place as well, some require actual visual contact rather than just an uninterrupted sightline, but basically you need to be aware of the drone's surroundings in case something else is in that airspace (birds or planes in particular) or if you're getting close to trees or wires that aren't in the drone camera's field of view. A drone without any proximity sensors means you're much more likely to hit things unexpectedly if its beyond your actual visual range, so I'd recommend you fly at higher altitudes (up to around your local legal max) until you're familiar with the area, and holding back from flying that low over water until you're comfortable with the controls and how the drone acts at low level over land.
Oh, and on a creative note, its good to think of the drone as a flying camera rather than an aircraft! Use the manual exposure and shutter controls (if available) to get the shot you want as though its just a camera on a very-mobile tripod, and for video you'll want to consider the motion of the camera both as part of the drone's movements and for the gimbal too (e.g. panning the camera up while moving backwards, moving sideways with a little forwards to create an orbit, etc). Remember that it's not just about documenting the flight of the drone, its for getting interesting images or videos that you want people to engaged with, so try to avoid videos of just flying straight forwards and mix in panning shot and rotating movement, along with changes in altitude and gimbal angle for maximum effect.

Got my first drone (also a Mini) in January 2021, but upgraded to Mavic Air 2 after about a year. My main reason to upgrade:Â wind. Mini was constantly complaining that the wind was too strong, and it was demanding to take it down and back. Once I nearly lost it over a mountain gorge where the wind was suddenly too strong and I could not get i back until I brought it way down almost to the bottom and then took it back up along the side wall without a direct visual contact, that was nerve-wracking. Mavic Air is bigger and stronger and so far never had any of these issues. Plus the obstacle avoidance... priceless. Another time when I nearly lost my Mini (soon after I got it, and was still unwisely cavalier) is recorded in this video

I bought my first drone a few years ago when the Mavic 1 was out. Never had "big" accidents, never lost 1 (I've had 4 of them, all DJI drones). According to my experience rule #1 - no panic, never. If you lose connection - and I lose it a few times, I wait a little bit to have the signal back and if I don't, I know that the drone will start to go back home. When I have the connection back, I take control of the aircraft again and I know that in that area I can't go further or that I have to find a better spot to help the controller to have a better signal to send to the drone. It's very important to take off in a clean areas with a lot of space around you. If the aircraft needs to be back by itself, it has plenty of space to land. About the "line of sight" issue I totally agree with Robert - it's impossibile to see it all the time. My drone goes very far, but only when it's "safe" - no over people, no in narrow valleys where there's no signal and if it needs to come back it has way to find a clear area to move etc.
Since your drone has no anti collision systems you have to be super careful. Anyways, if you fly very close to the water surface it won't land by itself, but it won't avoid waves (which can be dangerous even with the ones with anti collision systems).
You have to learn what it's safe and what it's not, what it's easy and what it's not. You have to check if there are cables, branches and all that kind of stuff which can be difficult to see when flying. If you have doubts about a certain area, don't fly there or go there before and check before flying. |

The big advantage on the lake is that there is little chance that the water will suddenly turn into high waves! Still, I haven't yet worked out how to be sure not to be too close to the water to avoid my drone "deciding" to land! Even in fresh water it would not be a good idea. |
Your drone has no collision avoidance, so that IS an issue for you. Go up one level and they won't let you get closer than about 3 feet to the surface in normal mode unless you're landing, which means flying only in a downward direction. With my drone, if I am flying fast and angle toward the ground it swoops up and levels off at about 3 feet. I can override that in sports mode but it scares me witless :-) The Mavic 3 will fly over 45 mph in Sport Mode...
