Refreshingly honest about the video quality you should expect in the main promo video. Typical problems like dynamic range, color profile, light bleed and tracking problems with the top of the head being cut off at one point. Pretty typical unless you spend more money on your drone or camera equipment. There are so many companies that fake the footage or pick much easier shooting locations.
- mrtksn 4y agoI was very surprised to hear the rotor buzz. Most drone promo videos pretend that when the motors spin, it makes moody beats sound.
- serf 4y agoI was too busy being deafened by Frank Sinatra a split second after the rotor noise played to even remember hearing the rotor noise; rather than faking the silence they just over-wrote my memory of it in the advertisement with shock-and-awe style Sinatra -- I guess that's okay.

- mrtksn 4y agoThey have plenty of videos, here is one without any music: https://www.youtube.com/watch?v=qpz8Q2spioo https://www.youtube.com/watch?v=qpz8Q2spioo I was positively surprised, despite the music. Some time ago I was very annoyed by all these "drone projects" on kickstarter or concept artist sites about drones following you all day as personal assistants, for example. IMHO, drone noise is just as limiting factor as the battery life and products should have it on their promotion materials, even if it is for a split second.
- andkenneth 4y agoAnd that's pretty much the idea - they expect you to put music over whatever you've captured anyway.
- shpx 4y agoBut while you're doing whatever it is that you're capturing, whether or not there is a loud humming noise the entire time can completely change the dynamic, especially if other people are around.
- sytelus 4y agoThere is probably a market for pocket drone that can carry iPhone and take selfie just like this.
- kelnos 4y agoI'd be pretty worried about an accident that damages my phone; I don't think I'd want something like that. But I wouldn't be surprised if some people do.
- the_arun 4y agoIsn't iPhone too heavy for drone to carry around photographing?
- ehnto 4y agoNot that I think it should be done, but since the drone is carrying the phone, you could have the phone save a GPS point of where you are standing, and then the phone guides the drone away from that point to photograph toward it. Depending on GPS accuracy in the phone it could work well. GPS waypoint missions are already well established in the drone world.
- walrus01 4y agoan actual FPV flight hobbyist 5" prop size class quadcopter (such as you might fly with goggles and a real remote control) can typically carry a gopro hero8/9/10 but a gopro is also a lot more compact, brick shaped, rugged, and has very extensively researched video stabilization systems in gopro's proprietary "hypersmooth" which writes the stabilized video into the HEVC file it records. putting something flat and large like an iphone on a 5" FPV quadcopter would be awkward and bad.
- thinkmassive 4y agoiPhone 12 mini weighs 135g, over half the 250g limit for mini-drones. It seems unfeasible for a pocket-size drone in the near future, unless the drone could pull power from the iPhone and not need its own battery. Mavic Mini has a payload capacity around 180g, but it also has a nice camera already.

- walrus01 4y agonot just wobbly but what small drone enthusiasts call "jello", significantly lower video quality than like a $399 dji mini 2 it is cheap and non gimbal stabilized, so can't expect much more
- marwis 4y agoAre there no better digital stabilization algorithms? This seems like it could be fixed in post processing on your phone/cloud.
- walrus01 4y agothere absolutely are, without a gimbal, by using a somewhat large sensor and movement/orientation/inertia sensor ICs to perform a software crop and stabilization as the video is recorded. such as the hypersmooth 2.0 or hypersmooth 3.0 on a gopro hero9 black/hero10 etc. but those are considerably more expensive cameras. search youtube for gopro hypersmooth 3.0 and you'll see some examples of the same gopro with and without hypersmooth turned on.
- WrtCdEvrydy 4y agoI've used Mercalli to fix this in post-processing but it's not a simple fix. This is caused by a non-global shutter so you have to spend a lot of processing power to fix it.
- saidinesh5 4y agoA recent, but really good, open source one is https://gyroflow.xyz/ https://gyroflow.xyz/ . There's also Reelsteady, Hyperflow etc..

- slg 4y agoThat is nice, but there is still intentionally misleading marketing fluff like this: >Each rechargeable battery allows you to capture content for 5-8 flights, depending on the flight mode(s) selected. Rechargeable batteries can be swapped for easy use... Why phrase it like that? That gives zero impression of what the actual battery life is because I have no idea what a "flight" means as a unit of measurement. Just tell us how much time it lasts.
- natural219 4y agoI don’t fault them for this specifically. IIRC the 30 minute airtime standard is some kind of FAA regulation; it’s not a differentiator one way or another between drone products.
- jhugo 4y agoThis drone will definitely get nowhere near 30 minutes.
- bushbaba 4y agoI have no idea on how many minutes it takes to get a photo. I personally like their metric choice.
- slg 4y agoI'm not sure that I follow what you are saying. Are you suggesting the expectation is that each flight yields one photo? It takes milliseconds not minutes to take a photo. I would expect this thing to be taking photos nearly continuously during flight which would make flight time the most informative metric.
- MegaButts 4y agoI don't think you're their target demographic.

- bozhark 4y agoThe image stabilization is garbage
- roughly 4y agoI think this is going to be one of those things where we learn that nobody actually cares about any of that outside these forums. MP3s were garbage, early camera phones were garbage, Snap picture quality generally is garbage, bluetooth headphones suck, all of these things were and are decried by the tech community, and it turns out that people just don't care, because even at garbage quality it's still cool to have a robot take your picture.
- bamboozled 4y agoHaving a robot taking your picture only sounds cool go hacker news people ?
- majormajor 4y agoEven without the robot angle "cool" aspect of a drone, it's a step along a progression that's shown clear demand: first selfies, then selfie sticks, then no-stick-needed non-selfie selfies.
- whatshisface 4y agoDrone photography predates selfie sticks.
- srcreigh 4y agoWhy isn't it trivial to cut out that noise? is it 4 motors? especially with data about current RPMs of the motors, with a FFT and some adjustments, it should be pretty trivial to deafen the sound. From my listening many motors are effectively pretty simple instruments with normal harmonics etc which are easy to model. I could be wrong though.
- meatmanek 4y agoThere's going to be a significant white noise component due to the turbulent airflow, which won't be as easy to cut out.
- samatman 4y agoThere's so much white noise outdoors that removing the dominant harmonics that make drones, well, drone,† would make a huge difference in the palatability of being around them. †The noise quadcopters make has nothing to do with why they're called drones, but is the perfect description nonetheless for the noise they emit
- williamtrask 4y agoIf they combined it with audio from the phone they would have a much better chance of isolating noise.
- sorry_outta_gas 4y agoIt also makes it seem more real and fun
- deleted 4y ago[deleted]
- ComradePhil 4y ago> video quality you should expect The video that they try to show as if out of the drone is heavily edited to make it look similar to the other camera that they have used. It is very likely that they used non-stock camera software in the drone to capture raw and post-process for this ad, which will most likely not be available to the public.
