Review: DJI Phantom 2 Vision, a high-end iPhone-compatible flying camera drone - Page 2

post #41 of 55

DJI is very slick with marketing.  There should be some fine print saying that results may vary depending on equipment used and skill.  While I know the Niagara Fall shots were with a Phantom, much of that footage was shot with their much more expensive high-end copters with professional video crews.

You could compensate by adding a gimbal -- but that would increase weight, battery and cost.

You can mitigate the problem by post processing the video.

Here's a short comparison showing a quick and dirty image stabilization with Final Cut Pro X. The areas under the bridge and the arch shows the difference best:



You can do a lot finer stabilization by spending a little time with the various settings.

FCPX can compensate for low light and punch up the video too!,


Edit: Oops, Sorry -- I originally posted this to YT as private ... OK, now!

Just wanted to say that I find this post here at AI rather ironic, that I just got finished watching on my sub channel on YT a different guy giving tips with the DJI 2 and GP Hero 3.

Note: really cool guy called Mic Bergsma who I've followed for some time now. He's a professional wake boarder, film auteur and GoPro specialist... all while being deaf! Inspiring to say the least... Oh yeah... and a Mac/FCPX user too... 1smoking.gif

Tha was one hell of a FCPX project you did there! Props to you!

The folks saying the video is jerky ... That's the rookie pilot. 1biggrin.gif

I live near a lake with hundreds of large gators, I'd love to video there.

I am sooooo looking forward to your video! Videos!

Yeah, that's quite a video! All I saw was some FCP7 editing to manually transform [enlarge] and crop the video to get rid of the propellers, etc. IDK if he did any stabilization.

When you do stabilization, it automatically transforms and crops, as needed, to minimize shake.

Sounds quite noisy. Why isn't this mentioned?
Also, can the green and red lights be turned off? (Think: stealth operation).
It would be nice for a drone to use sonar techniques. Then it could also fly itself without bumping into anything.

As it turns out, it is not possible to use the GoPro's WiFi preview at all because it interferes with the controls for the aircraft. To see what the camera is seeing the way one can with the Vision requires additional equipment and a dedicated video monitor.

That's true. However as with anything pixel-based, it's always better to try and get the absolute best quality out of your equipment first... then tweak to your heart's content later with software.

I was only pointing that he's an FCP and Mac user in general. He has some interesting ideas, tips and solutions to getting the most out of a GoPro.

Not like I have to tell you that. Just letting you know what I know, and others mit consider before going the "post production" route to clean up what could have been done easier with a little more knowledge of the equipment at "take" time... 1smile.gif

Exactly!  Something about a "making a silk purse ..."

I misspoke ... FCPX doesn't automatically transform and crop -- I did that manually by scaling the video 143.1% to insure that the edges stayed within the frame.

Here's the clip without any scaling -- it really shows how stabilization compensated for the jerky camera movement:

Woah! Not bad! In a pinch a good way to save a "shake-n-bake" session.

SOT:

Not really related to the DJI, but this shows a OIS video chip that is rumored to be in the next iPhone:

Late last week, shares of InvenSense rose on rumors that the company had won a contract to supply sensors for Apple's upcoming iPhone 6. InvenSense supplies sensors such as accelerometers and gyroscopes to major phone manufacturers, but the company has yet to publicly land a deal with Apple. The validity of the rumor seems up for debate, however, as a Needham & Company analyst soon released a note saying that he "did not get the impression" from InvenSense's CEO and CFO that such an agreement was in place. Of course, that information would be under a strict non-disclosure agreement with Apple, severely limiting what InvenSense executives could tell the analyst.

Regardless, The Motley Fool speculates on what InvenSense could bring to Apple. While InvenSense could offer drop-in replacements for the current gyroscope and accelerometer sensors in the iPhone, the company also provides Optical Image Stabilization (OIS) technology for mobile phones:

There's one additional socket that InvenSense could win on the iPhone -- an OIS gyroscope. The burgeoning technology is used to improve smartphone camera's by stabilizing the image using a gyroscope. Samsung neglected to use the technology in the Galaxy S5, but Apple may decide to integrate it into the iPhone 6. If it does, InvenSense is a clear choice.




Optical Image Stabilization remains relatively new in the smartphone market, and uses a motion-tracking system to compensate for device shakiness, allowing for sharper photos and video. This video demonstrates the product:

Looks like a fun 'toy' with clear but limited useful application for the average user. This drone thing will be the next GoPro craze. At least until reports of injuries such as children's fingers being cut off by the fierce and seemingly un-protected propellers.

Deviating even further off topic, who wrote the piece you quoted? It's full of grammar and language errors.

 

The democratization of publishing offered by the web has a downside: the absence of a skilled person to vet and edit copy before it goes to "print."

According to the websit, it was written by Arnold Kim -- the head honcho at MR.

I doubt that the "average user" has much use for this - it's just a very expensive RC helicopter unless you need its capabilities. But as a relatively long-range, long-linger, and autonomous (if necessary) aerial video, photography or surveillance platform, if that is what you need, it is quite powerful. It does have optional propeller guards.
