Most Common Animation Mistake In After Effects and How To Fix It – Wobbly Keyframes

March 27, 2009

The “Wobbly Keyframe” problem has been plaguing After Effects animators everywhere. I made this short cast on how to get rid of the problem.
If your not sure what it looks like, check out this video.

Sick of my face? Want the three step program to obedient keyframing? Here ya go…

Step One: Select the offending Wobbly Keyframes.

Step Two: Right click and select “Keyframe Interpolation”

Step Three: Set Spacial Interpolation to “Linear”

Tutorial Focus:  ,

  • When I was just starting out this gave me the most headaches and I could never find anywhere that told me what the deal was. Great that you explained it for everyone.

    Also – another workaround would be to use hold keyframes.

  • I’ll be watching this later today, it’s going to come in handy

  • This issue is described in the tip at the bottom of the “Controlling change with interpolation” page of After Effects Help:

    There’s also a good pair of tutorials by Aharon Rabinowitz about this:

  • Sometimes I watch these beginner tutorials and I think to myself, whatever, I know this stuff. But there’s always some tiny morsel to learn in after effects.

    Case in point, I had no idea the motion path color corresponded to the layer color. lol

  • thanks nick, that is one of my biggest problems. you helped me a ton. nice “the more you know” reference to.

  • Thanks a lot fr this post nick!! i have this problem most of the time. Finally i know how to fix it. i have a question tho, do you know how to create “double vision” effect in after effects? you know to show those “drunk” feeling

  • Love your site Nick! keep it up.

    To get ride of this keyframing problem I always go to…AFX Preferences, General, click on “Default Spatial Interpolation to Linear”.

  • Great Tip Brook. Also, maybe someone can find Zee a link to a Double Vision Tutorial? Ill keep my eye out.

  • Thanks so much for this! An annoyance I didn’t even know could be fixed. Sorted.

  • Thanks so much for posting this Nick. This motion path wobble issue has been a source of frustration for many years.


  • veryyy grateful for sharing this awesome tip.
    may God bless you 😀

  • you could also select the keys and, with the arrow tool selected, hold down ctrl+alt (which changes the arrow to the “carrot” tool) then click in the composition window on one of the selected keys. different method, same result. 🙂

  • Wow, this has been a problem for me for a while. Thanks so much!

  • thank you sir! I never understood why it did i would get soo pisssed i am so glad i know ho wot handle that punk ass “wobbly keyframe” when he shows up again lol thanks again

  • thank you so much for this!!!

  • Aaaaah!! I can’t remember what I was doing.. I had something orienting along a path.. and the objects would rotate around uncontrollably.. I spent hours trying to get rid of the bezier handles with the pen tool..

    Thanks for that!!
    ‘ll check out those adobe links

  • Thanks mate, i totally forgot how to do this and it was annoying the hell out of me!!!

  • First of all, thank you for this useful tip.. And yeah, this was happening to me very often when I was a rookie.. Actually I have found the solution accidentally while I was clicking every right click menus.. Where were you man in 2002? 😉 I have spent lot’s of time to solve this… Anyway I saw this link in aetuts+ and liked your all tips.. They all work well, except tilda key.. Because we don’t have tilda key on our keyboards.. Do you know how to assign another button, for full screen issue? (Language is TR) Thanks again…

  • I had that once but I tried to fix it in graphs, and failed.

  • Gosh. THANK YOU SO MUCH! 😀

  • Thank you so much. Took me an hour to solve this shit, until I found your article <3

  • Hi! greets from Buenos Aires Argentina!
    Gosh, If only I knew this!!!

    well, next time Ill do better!!!
    thanks so much for your help, really I stated from zero this year in my last year of Graphic design school… and didnt know shit about after effects…you are my hero!


  • Hey!

    I was struggling with this problem for like an hour. Thanks a lot for saving my day!

  • Well this pretty much saved my life, thank you thank you.

  • Thank you so much for this solution, it was driving me nuts!

  • thanks heaps.. i used to do it with avid and all you got to do is select linear, thanks to you i can use ae now! cheers!!

  • thank you so much for this!

  • Very helpful thank you!
    Are there more tutorials on AE ?

  • this is the number one mistake to fix for adobe but they dont care. fuck auto brezier

  • I guess, i’m pretty new at this and i need more help… 🙁 I don’t know why, but this helps me only on the first stop… i want my object to stop 3 times, but this works only on the first time. I mark all the keyframes…. 🙁 what may be the problem?

  • I just wanna say: I love you man! 😉

  • Haha, to undo this problem i duplicate the frame, but now i discovered the solution! It’s way too better now, THANKSSSSS!

  • This really is a terrible part of After Effects. I know there’s a logical explanation for it, according to some, but really, this is just the worst. Who would want this to happen? Ever? Thanks for the post!

  • Man… I LOVE YOU!!! Thanks for explaining this WONDERFUL tip!

  • This has been driving me crazy for days! Thanks so much for info.

  • I came across this problem several times and tonight for the first time (after 6 years of using AE) i google the problem and i find the solution.
    Thank you Nick.

    PS Do you have anything i common with Russell Crowe lol. You look a lot like him.

  • HOLY CRAP, I actually know how to fix this now, thank you soooo much, i’ve being using AE for the last few years and this always happen and i have no idea why it did that, always ended up clearing the keyframes and doing it all over again – such a waste of time and was super annoying. Awesome sauce, can’t believe i didn’t find this video sooner! Thanks again.

  • Thanks for the video, I had run into the problem a few times and it’s nice to know what’s going on and how to fix it!

  • Thank you so much! You’re a life saver!

  • Awesome!, I had this problem a few times ago and you just solve my life 🙂 Thanks!

  • Thank You so much!

    I am still an After Effects novice and I made this very mistake. Your tutorial saved the day and was quick and to the point.

    Thanks again,

  • nice and ESSENTIAL tutorial for beginners

  • I luv you man!

  • Thanks so much for this. I always just went back in and edited the kinks manually and knew there HAD to be a better way and your video is the only place that talked about this!

  • Great tut man! And it´s still useful after all these years. Just one thing, what if I want to keep my spatial interpolation non-linear? Meaning I want to get rid of the woobly movement but I don´t want my layer movement to be a straight line.
    What I did (most of the times it works) was to convert the interpolation to linear, just like this tuts explains, but then make the position lines curvy again by hand (using the convert vertex tool).
    And by the way, this problem arises whether or not you have the “Default spatial interpolation to linear” option selected in preferences (if you tried to make a bezier interpolation).


  • THANK YOU SO MUCH FOR THIS!!! Same thing in CC (2014)!

  • Thank you, guys!

  • may every god bless you, thank you!

  • Need that on my first AE Project. Many Thanks from Austria.

  • Thank you, it was driving me crazy. I’ve been dealing with this behaviour for about a year, always deleted and keyframed again and again… Luckly I found this page/video. Thanks 🙂 6 years after your post lol.

  • You just saved me a lot of time and frustration. Thank you for putting this together!

  • This is great, but when I set Spacial Interpolation to “Linear” it straightens the path, and I want it to remain a curved path.

    Additionally, it’d be nice to find a way to delete keyframes from a path, in much the same way you’d delete a point with a “Delete Vertex Tool” pen, and still maintain the path shape.

  • I took out so many animations for not being able to solve this issue, this tip saved me

    You’re a trooper

  • Thank you so much!!!! I have been struggling with this problem for years!! I always had to make a null object to change the interpolation….
    Thank you!

  • I got it! Thanks for sharing!
