Jerky Animations on iOS 4.1

Since updating my iphone 4 to ios4.1, the animations are extremely jerky, especially when opening an app. There is a noticeable stutter before the app opens - it does not pop up smooth. Apps also seem to crash more often. Anyone else noticing this?

It's funny, I just updated my old iPhone 3G to 4.1 and from being super sluggish since 4.0 it's now very fast and everything is very smooth.. Yesterday I recieved my iPhone 4 and I updated directly to 4.1 and even though the phone is super fast I see this stutter that you're talking about - it's quite annoying! Also when you search in google, it sometimes hangs - it's doing the search like 10 times fast and then gives me the result. Some strange bug.

Export AE Animation into iOS

I'm working with an illustrator to take After Effects animations and put them into iOS code (SpriteKit specifically).
We would like an automated system that takes a complicated After Effects animation (like the one below) and turns it into something iOS/Objective-C/SpriteKit can understand. Or, if this is not the correct process, how do others usually create AE animations in iOS?
Here are a list of resources that I've explored, but none of them actually solve my problem:
Work with Adobe after effects. Possible or impossible? - Cocos2D Forum
CreativeCOW
After effects for game development? | BP | I make video games and fun software by fractional distillation.
Thanks in advance!

As for AE, I haven't found anything additional to the links you have provided in your initial post. By the way, have you tried the GibsonXML + Shade Dogs scripts approach from bp.io? Is it worth using and adapting to SpriteKit?
Here's some kind of a summary of the options that use Flash or other design environments:
Flash > Flump (open-source) > Starling (cross-platform) or Sparrow (open-source Objective-C 2D game engine)
Flash > Flump (open-source) > Build a custom SpriteKit runtime for Flump's JSON output
Flash > DragonBones plugin (open-source) > zrong/dragonbones-for-cocos2d-x · GitHub for cocos2d-x
Flash > DragonBones plugin (open-source) > Build a custom SpriteKit runtime for DragonBones JSON format
Flash > open-source converters/players such as musictheory/SwiffCore · GitHub (looks like a plain Flash player on iOS) or gree/lwf · GitHub (includes UIKit runtime); they do not support SpriteKit out of the box.
Spine (license required) > one of the official runtimes for cocos2d-iphone/cocos2d-x/Unity/libGDX/Starling/etc. There are also two unofficial runtimes for SpriteKit, see this tutorial: http://www.raywenderlich.com/59535/integrating-spine-spritekit-tutorial
Level Helper 2 (free trial) supports SpriteKit
SpriteBuilder (a.k.a CocosBuilder) > cocos2d; they've also had SpriteKit support but abandoned it. See apportable/SpriteBuilder-SK · GitHub
Flash > GAFMedia extension (license required) > cocos2d-iphone/cocos2d-x/Starling/etc.; no SpriteKit support
It would be great to use SpriteKit but it looks like it is required to build your own custom runtime first to support animations produced in Flash or AE.
Have you considered exporting AE projects into Flash?

Choppy/Jerky animations iPhone 5c 16GB iOS 8

After updating my iPhone 5c to iOS 8/8.1 it's really choppy. Choppy animations/scrolling in the Notification Center. Choppy animation when pinching in/out of cities in Weather. Is there someone who has got any similar problems with the iPhone 5c? Is it normal because it has the old A6 Chip or is it because of iOS 8?

I Have the same problem on both my iPad Air and iPhone 6.
For me, the only way to fix this is to turn off automatic updates.
Does someone knows how to fix this with automatic updates on ?
thanks

Slightly Jerky Animation

I have noticed some of the animation in the following flash
piece is a little jerky, and I wanted to see if anyone had any
ideas on how to make it a bit smoother. I know I can increase the
frame rate (currently at 20, thinking about going to 24), but it
may not make too much of a difference. Any ideas?
Start at
http://www.ascenths.com/collections/
but that intro piece isn't what I am worried about. Click to
launch and flip through the content of the big piece. I am mostly
noticing the alpha fades and the masking effects on the very large
photos.
Also, can anyone tell me exactly what "compress movie" does?
Will I get an improvement if unchecked? Is it worth it?
All input would be appreciated!
Thanks!

I think there are performance issues (bugs?) with iOS 4. I've posted about jerkiness myself, as have many others. Just search for "jerky" and you'll see them all. Also, look at all the posts regarding battery usage when nothing is running.
If I saw this behavior on any other computer system, I'd say there were processes running that are gobbling up CPU time, memory, and in the case of the phone, battery.
In my case, I think there are runaway mail processes. The performance of my phone improves drastically when I inactivate my mail account.
Other people may have other runaway processes.

Jerky Animation (Video Link) - WHY?

I have a simple animation with two keyframes moving horizontally. However, the movement staggers or 'chugs' across the screen.
Look: http://img21.imageshack.us/i/staggeredvideo.mp4/
That's not the actual ad, but the same mishap occurs.
Set up
AECS3, 30fps (same result at 29.97fps)
Several layers attached to a null object
The null has two keyframes (regular *diamond* kfs - same result with varied easing kf types)
The null moves the objects in time across the screen from point A to point B
Result - Jerky movement
Question: Why?Is there a way to resolve this?
I asked the awesome folks on Creative Cow, but thought I'd seek assistance here as well. Thanks in advance!

I don't see any staggering - and that on a machine that is currently rendering a 3D animation in the background and has a processor usage of 90%. So in all fairness, what you see are most likely issues with your local computer configuration/ hardware performance.

Jerky animation opening emails

I've got my 3GS set up to access my gmail via IMAP and my Hotmail accs.
More often than not, when opening emails, the animation of opening and displaying each email is somewhat jerky.
Anyone else having this problem?
Simon.

My email does the same thing. The phone froze 4 days after getting it. When I go to open an email it jerks for just a bit and then opens. I've tried resetting it. I'm wondering if I should restore the whole phone?

Adobe Edge generated animations won't play on Android Devices (PDF Stack animation only iOS)

Hi,
I'm was using Adobe Edge 1.0.1.204.X (Windows 7 64bit) to generate a simple animation in order to export it as OML and place it in Adobe Indesign CS6 (Windows 7 64bit).
The animation is as follows:
Backgroundpicture (1024x768) fades in
Three textboxes fade in one-after-one
Then I exported the Edge-Project as .OML and placed (CTRL-D) it on my Indesign Folio. When I try to test the Folio locally on my Windows machine it throws the following error: PDF-Stack only supported by iOS Devices. Then I tried it on my Android Phone and it threw the same error. Does Adobe plan to integrate the PDF-Stacks into Windows and/or Android Viewer?
Best
Marcel

PDF format is not supported on Android, save your folio as jpg or png.
By the way everything you describe can be easily done in DPS, andy reason to be doing it in Edge Animate? just curious :-)
Cheers

Keynote animation for ios

Does anyone know of anyway to include a keynote animation in an iPad app.? The plan is to design a keynote animation and pass it over to our iOS iPad developers to include within the App build. Not sure if Keynote is the right way to go though. Anyone with ideas welcome.

I would check with the [iPad Keynote forum|http://discussions.apple.com/forum.jspa?forumID=1369], they may be able to help you better as we don't all have an iPad in this forum.
Here is the link to [provide feedback on Keynote|http://www.apple.com/feedback/keynote.html] if you want Apple to include this feature.

Need help with jerky animation in Flash CC

Hello,
I'm creating an animation of a planet orbiting the sun and it is stuttering a little bit no matter what I try. I'm working in Flash CC, the animation is done with a custom ease and only 2 keyframes (one at the slowest point and one at the fastest). The end result has to be .mp4 so I am exporting as video. But even the swf is a little jerky. My frame rate is 29.97. The animation path is oval in shape (using an oval guide path which the planet follows), the planet is small, maybe 6 mm across, and the planet's speed varies as it orbits the sun (thus the custom ease). The number of frames in the animation is 202, that's how long it takes for the planet to complete one rotation. That anim is then looped in the movie as a graphic.
thanks in advance for any help you can give.

Here would be a similar example, linear versus an ease tossed in. I made an oval similar to yours (633px by 446px) and just used it as a guide:
Here's some videos showing the movement I get per frame. You can even see Flash Pro (CS6 in this case) exporting some odd frame choices. For example right before the 5 second mark the circle jumps 2 movements and stays in place for an extra frame (easy to see stepping through it using arrows and Quicktime player). It does this consistently even when using "None" for Quicktime compression, or using a codec.
Here's some video examples (30FPS over 202 frames, 6.7 seconds):
Linear Movement
-60 to 60 ease at the opposite side
(Source MOV (Animation codec @ 85 quality) to verify MP4 is the same)
I imagine your results are the same. It's just too much movement for to little time to really get it to play back smooth. Double the time and you'll cut that in half and I think you'll be happier. Increasing FPS beyond 30 might not be a good idea as playback will start to become machine dependant at that resolution and it could bog even worse.

Choppy/Jerky Animations on Verizon iPhone

*I'm having an issue with my new Verizon iPhone, at random times for example when closing an app or scrolling through settings the animations and scrolling become very choppy and unsmooth. I was wondering if this is a normal thing or something I should be worried about.*

I am experiencing the same issue. It usually happens when I open or close an app. I have read that it could be iOS 4.2 related but not sure. My buddies iPhone 4 with the 4.1 software never has choppy animations.

How can I re-enable the nice navigation animations in ios 7.0.3?

The questions says it all:
The fade in/out is annoying. How can i disable that and have the animations back?
Thanks!

If you enjoy the animations but find the parallax effect a nuisance, you should send Apple feedback to have toggles for both. I've already done it!

Jerky Animation

I play Fish World in Facebook, & sometimes the 'fish" swim across the screen in a "jerky" movement....How do I correct this?

I run it in chrome on the iPad and it is running smoothly.

IPhone 4 get stucked in animations in iOS 7.0.3

Hi everyone,
Since updating to iOS 7.0.3 my iPhone 4 get stucked in the transitions when:
- From lock screen, use de camera. The lock screen moves up a bit and then get stucked at some point
- In desktop, when using control center, it get stucked at some point when is moving up, it doesn't fully spread all the way
- Sometimes, when navigating between desktops, it get stucked in the middle of them.
I have made restoration and load my iPhone copy, everything is still the same?
Any other person with this issue?
Regards

Hi, Escarcha.
Thank you for visiting Apple Support Communities.
I would close all applications in multitasking and power cycling the device. Once this is done test the results.
iOS: Force an app to close
http://support.apple.com/kb/ht5137
If you are still having trouble with the text appearing as you type after following those steps, you may want to try turning off Documents & Data under your iCloud settings. On your iOS device’s Home screen, go to Settings > iCloud, then tap to turn off Documents and Data.

Is there any way to turn off the "zooming" animation In IOS 7?

The continual zooming / animation that occurs every time I move in and out of an app, is incredibly tiresome after a while - especially when using multiple apps for business. Is there anyway to turn this off?

No there is now way to turn off the screen animations, with the exception of the paralax effect (The moving background) which is what the Reduce Motion option is for.
If you really hate the effects, you need to submit your feedback via Apple's feedback page, http://www.apple.com/feedback
They don't really monitor these forums for this type of feedback. There are a lot of threads that address this problem and some people have even reported becoming motion sick because of the zooming in and out effects.
