Hi All,

Received my Phantom 3 yesterday. Read through the instruction manual front to back, charged everything up and took it out for the first flight this morning. Much to my disappointment, I was noticing a fairly noticable jello effect on the video (yes I removed the gimbal brace...) I'm chatting with DJI technical support now and will let you all know how I fare. Is anyone else experiencing this issue? What do you all think? Gimbal issue? Prop balance issue? I'll work on uploading a longer clip later (that shows the effect MUCH more noticably) but for now here's a quick clip:     Also - seems as though I'm not the only one... ()

Make sure you take off the polystyrene block from behind the gimbal... Also remember to remove the plastic film on the front of the lens ;)

When you say that you removed the brace, do you mean the plastic piece? There is also another WHITE FOAM piece attached to the gimbal that needs to be removed.

*Raises eyebrow* That..may...do it...
In all my discussions with the techs and reading the boards, I was under impression it was a flat piece that sat between the shock dampener plate where the camera hangs from and the body of the aircraft. It may be that I looked right past the foam as it may have blended it. I'll take a look as soon as I get home... (darn work getting in the way of my fun!!! haha). Sploodge & vmp - thanks for the replies and assistance!

Interestingly in the few unboxing videos I've watched, none of them have removed this piece of foam from behind the camera/gimbal??  I don't remember even seeing it still attached??

It's difficult to miss it, there is a red sticker with "Remove before flight"

Turns out when it was packed originally, it looks like they tore that foam padding. I found part of it at the bottom of the box and there was a small non-visible piece that was still wedged in there that was causing the issue. NOWHERE in there was a red sticker that said "Remove before flight"

Once removed, the video was absolutely gorgeous!

Wow!  I had the exact same jello problem, and the foam padding was also the culprit.  In my case, the foam was intact and did not have any "Remove before flight" sticker.  Very easy to miss this when unpacking.

I have removed all the packaging (although the first flight did have the piece of foam still attached) but there is still a marked jello effect . The video also shows how jerky a basic pan is. Are there any specific settings for the camera to overcome this? Is there away to de-sensitise the sticks to get a slower response? (I have already lengthened the left stick (Yaw) to try to slow it down)

Does any body have a clue what is causing Jello effect in my video? Everything is removed, no Styrofoam pieces,  nothing all clear. When I played my video back on my PC "media player" the video was clear and awesome, BUT!!! there was jello effect. Could it be I am using MOV format and not MP4 ? Thank you for your knowledge.

has nothing to do with jello at all, its caused because of vibrations not a file format. Im sorry but i guess you saw something different or placebo effect. I used MP4 since i got it, it will change nothing

Turn more slowly. When you think it's going to take forever to turn, slow that down too!

I feel your pain. In 4K mode it seems very difficult to pan slowly enough - virtually anything seems too fast. I've been using three tricks:

(1) Screw the turns/pans - cut 'em out during the editing process! (Create a transition so you "flow" from one scene into the next.)
(2) Practice, practice, practice
(3) Instead of stopping and panning, try moving forward *very* slowly and turning *very* slowly at the same time. It may just be my opinion, but it certainly seems like the forward motion either detracts or subtracts from the "bumpy" feeling the pan produces.

aburkefl is right, slow it wayyyyy down. You'll be pleasantly surprised when you see the results of painfully slow turns. Also, the sticks have notches in them to help you visually check your speed. Test these out, turn by only going 1 notch left, then 2, then 3, and so on. When you watch the recorded video you'll be able to tell what worked best for you and what you like. The more you practice the more 2nd nature this will become and you'll hit those marks without much thought.

Shop diagnosed a faulty gimball, sent in today so will report back soon. If you power up without props, then gently touch the side of the gimball you can feel it vibrating, I think it's a gimball motor fault?

You're in the U.K. so your sun may not be as bright as others are used to. You *do* get *some* sunshine once in a while don't you? Just kidding!

One of the other posters in this thread is in the U.S. I don't know where he/she is physically located, but, if it's in an area where they can experience bright or very bright sunlight, all that light is often the culprit of the dreaded jello effect.

You can adjust your ISO only down to 100 - you cannot go any lower than that. On a really bright day (and even on not-so-bright days) ISO 100 is simply not nearly low enough - too much light gets to the camera sensor, trying to "blow out" the exposure. The auto camera system compensates for so much light by speeding up the shutter, i.e., trying to keep all that light down to a dull roar. Then your shutter speed suddenly becomes a big problem.

The shutter opens and closes so rapidly that it barely has enough time to capture the information it needs to capture, then it slams shut (figuratively speaking) and starts another sequence and you suddenly experience a "shifting" of the image because it can't quite "catch up." This "shifting" effect from frame to frame creates what everyone now identifies as "the jello effect." It looks like all your images (frames) are shimmering as if they were pictures painted on the flat surfaces of jello.

One other problem. You can pan (rotate on the camera/Phantom axis) faster than you can fly - in *any* direction. Now, with a very fast shutter speed, if you're panning, you'll create this horrible "choppy" effect. On the plus side, if you needed to capture a still from that piece of your video, a very fast shutter speed will stop the action. But, all other things being equal, you'll get this "...I think I'm going to throw up...." reaction from viewers (and you as well!) reaction to that fast panning motion.

Put some sunglasses on your camera (ND filters) and you'll regain better control over your choice of ISO, slow the shutter speed down and even the panning starts to get smoother.

The bad news in all this? Even with that, you can accomplish terrific improvement with the panning/turning by sloooooowing it down as much as you can stand it. Eventually, we've been promised a feature known as POI (Point of Interest). POI lets you "target" something and fly by/around it, keeping it constantly in the camera frame. With a decent amount of practice, you can learn to do fly-bys and circling objects with POI. From what I've seen, though, the POI can be very impressive!

Enjoy!

This is the key to the problem, the gimbal vibrating is what is causing jello, nothing else.

I know this suggestion was put up awhile ago, but.....Thank you thank you thank you thank you!!!  

I got my P3P this week, took a dozen videos that looked absolutely horrible with jello, bouncing and vibration.  I was about to return it to the store when I stumbled on this post.  Sure enough...little white foam piece right between the gimbal and the unit.  Removed it, now the videos look just as good as what I'm seeing online.

Thanks again!!!

I rec'd my P3S and there was no foam piece at all holding that gimbal .... only the clear hard plastic gimbal lock and sticky tape across the flat area. I have that slight jello effect in all my videos ...

I have done IMU and camera calibration ... done everything possible.

Here's a video as example from it ...

DJI said would send a shipping label . All I got was an address to mail it myself and pay shipping both ways . Was told there would be a 10- 15 day turnaround on fixing it .

You can expect "jello" effect after the first crash. The props need just one little nip, scratch or scuff... and thats all it takes. Replace the scratched props, then buy a cheap, second drone for FPV-style flying.  Newbies don't fully realize Phantoms are made for slow, professional photography. Don't confuse an expensive drone to a bag of DORITOS.
