Fun With Precomping in After Effects

April 6, 2010

In this short tutorial, I show you how to make a complex animation with only a few keyframes with the power of PRECOMPING!!! I do this all the time in projects, and it creates some really fun animation.

    My fav part was “Bloop, Bloop, Bloop BLOOP!” :)

    Thanks Nick!

    Nick,
    So glad you posted this! I am in the middle of a project and importing illustrator files (clicked the rasterize button). Then I have animated them, PRECOMPED them, and once in the final scene (w/camera) I’m getting pixelated. This is probably SO rudimentary to all the AE Gurus out there.
    What’s the trick? What am I doing wrong?

    Share the love.
    Thanks much Nick!

    Hey Joshua,

    Make sure the illustrator layer and the precomp it’s in are both rasterized.

    Also, is the illustrator file an .eps or an .ai? I rememeber having some problems with pixelization with .eps files and I just saved it as an .ai file.

    Joshua

    Chris,
    Thanks! When I put the AI file as rasterized (before the pre-comp) everything is fine. Once I rasterize the precomp (the final scene w/camera) it becomes invisible. (You still see that there is SOMEthing there but the actual shape is invisible.

    ??

    Hm, just tried to recreate your problem but everything seems fine to me.

    Here’s what I did:

    1) Imported .ai file
    2) Dragged .ai file to ‘Create a new Composition’ button
    3) Ticked rasterize and 3D buttons on the .ai layer
    4) Precomp’d the .ai layer – chose ‘Move all attribute into the new composition’
    5) Ticked rasterize and 3D buttons on the new precomp’d layer
    6) Created a camera and moved around
    7) Went back here and typed this…

    Hope that helps!

    Joshua

    3D!
    thats its! SO SIMPLE! i breezed over the 3D buttons in first layer (before precomping) so that when I was 3D for the final, it couldn’t find 3D attributes.

    damn! Chris. thanks! really appreciate it.
    thanks again.
    It helps a lot!

    Again you pull me from work to watch your tuts Nick!

    It would’ve looked cool with some d shadow like you said. All one would have to do is put it on the original circle and BAM! – all 30 kajillion of those circles get the drop shadow.

    Oh and being a big keyboard shortcut guy, Command+Y (New solid) and Command+Shift+Y (Solid Settings) has collectively saved me hours.

    Anyways, I have an odd craving for some fruit loops right now…

  8. Christopher S. Knell on April 6, 2010 said...

    Good stuff! Looks like fun.
    Hey Nick,
    Will you be at NAB next week? Working any particular Booth?

    The Gorilla

    Yep, Ill be at the Maxon Booth. See you there?

    Christopher S. Knell

    Sure ’nuff.
    Me and my boys are shooting booth interviews for “Studio Daily” all week and I’ll be cutting them for immediate posting to the website.
    Staying across the street for easy access to the ‘edit suite’.
    See you there!

  9. Daniele Pauletto on April 6, 2010 said...

    Very cool Nick, thanks!
    And happy bday!
    ciao!

  10. DaniSang on April 6, 2010 said...

    Happy Birthday m8 – and this was a nice tutorial to refresh my mind.

  11. Sergei Tatarinov on April 6, 2010 said...

    hey Gorilla, thanks a lot for this cool sh!t

    i always need somethings like this to push my thinking and to come up with some simple but cool stuff on my own, thanks again

  12. Sergei Tatarinov on April 6, 2010 said...

    and happy birthday if it wasnt a joke :D
    at first i thought it was.. but then.. spending time on making tut for a loyal chaps is exactly Gorilla’s style, much appreciated style of course. So thanks again for sharing and all the best and just all the awesomeness in the world for you, happy birthday Nick ;)

  13. Paul Agostinelli on April 6, 2010 said...

    Great reminder of how fun and simple after effects can be, its faster than sketching!

  14. Sergei Tatarinov on April 6, 2010 said...

    damn, i’m stuck :) my memory’s telling me you’ve had your birthday not so long ago..

    The Gorilla

    Your right, actually. I recorded this tut on my birthday a while ago and forget to put it out. I found it today and put it online.

    Sergei Tatarinov

    I see, thanks. And.. hmm.. is there something more that you have, being covered with dust? I am eager to see more, cuz your stuff is always hit the top of all charts :)

    Sergei Tatarinov

    your stuff always hits* sry, am sleepy :)

  15. Juan on April 6, 2010 said...

    Dude! Great as usual!! Thanks for everything Nick! An out to date cheer for your birthday, hope you had a great day =) Take Care!

  16. Kurtis Thomas on April 6, 2010 said...

    Thanks Nick!! It’s awesome to see how such a simple beginning can create a deep and awesome animation. I tend to overthink things a lot in AE and this has helped to remember that sometimes simple is better!

  17. Alex Sparks on April 6, 2010 said...

    You should make the next 5 Second Project based on this technique.

  18. Noel on April 6, 2010 said...

    Excellent. You the man.

  19. Roald André Pedersen on April 6, 2010 said...

    I just love theese “KISS” (keep it simple, stupid :P ) tutorials! I personaly learn lots more from these than those super advanced tuts (thou a good mixture of both is superb), cause it just gives you so much room to play around with! Thansk for yet another awsome tutorial…

    And ohh yes, happy birthday you big hairy gorilla! :D

  20. sjoerd wijn on April 7, 2010 said...

    hee nick,
    nice one, looks really cool. gave me the little big planet feeling.
    thnx

  21. Brandon on April 7, 2010 said...

    Do you have to ‘continuously rasterize’ when you do this, since its vector based? Or do you not have to do that for masks?

  22. Vladimir on April 7, 2010 said...

    Similar design http://play.ukr.net/videos/show/key/9bdaddc97c4be6a6a472fcaf6eff16e2/ …Was it made similar like tut?

  23. Mark Shingleton on April 7, 2010 said...

    That’s really nice stuff Nick. I knew about precomping but never thought to try multiple levels of it. D’oh.

    Here’s my spin on it.

  24. Toby on April 7, 2010 said...

    You can do this kind of thing pretty well in Particular by using the circle animation as the partical. Cuts out all the copying and rotate/move stuff too.

    Plus the shading option gives you the shadows for all the circles, which looks pretty nice! :)

    Cheers Nick!

    Ajandi Endre

    Hi

    Particular limits your layer to 100×100 pixels. So if you want to pan through it or a flyby you will have jagged circles. Also, precomping gives you total control over the elements positioning which is more fun and looks better in the end

    Toby

    Hey Ajandi,

    Particular will only give you a warning about that if you use something gigantic.

    It’s quite possible to go over 100×100 pixels if you want, and your computer can take it.

    I was just playing with one using a comp size 300×300 pixels. Worked fine. :)

    Chrongram

    Nice,that’s new to me. I learn something new everyday! Thanx! :)

  25. Maciej on April 7, 2010 said...

    Hey Nick ! Great tutorial as always..

    Quick question : How do you make some changes in just one of the precompositions without changing all of them ?

    Let’s say I duplicate the first precomp to have one version who will be quick and a second one who will be slow.. (“Original Circle1″ and “Original Circle2″) How do ou do that ? When I change one it automatically changes the other one as well.. I tried to change the names of the precomps but it doesn’t seem to work..

    Davy Menge

    That’s not possible without another version of the original, with different keyframes. At least that’s the easiest way.

    Nick’s precomps all use the same comp as a reference so you can’t make one slower than the other.

  26. cristian on April 7, 2010 said...

    great tutorial…i wanted to learn how to do this for a while..congratulations..

  27. Bruno on April 7, 2010 said...

    Nice man! Make more After tutorials!

  28. Peedy on April 7, 2010 said...
  29. Christina on April 7, 2010 said...

    Quick question Nick, any way to click-drag-duplicate in AE? I often try the Photoshop trick of option drag but that just gives the wireframe in AE. I think you did it once or twice in the tutorial (the option click) and wanted to ask. Thanks for all the great knowledge!

  30. Jeff Mackey on April 7, 2010 said...

    Have you considered using screen capture software that shows the keys that you are hitting when you’re recording your videos? It would be nice to be able to see the shortcuts that you’re using. Sometimes it’s the little things that make everything a lot easier and faster.

    Paul Agostinelli

    The software is screenflow, it is capable of clicks and keypresses, many of his other tutorials use them actually.

    Jeff

    Cool. Thanks. Nick does a great job on this website.

  31. Matt Duplessie on April 8, 2010 said...

    Hey thanks for the great inspiration Nick!
    Looking forward to hearing you speak at SCAD’s Comotion event.

    Take a look at what I came up with using this technique here:

  32. Abel on April 9, 2010 said...

    woow, cool, maybe a good idea for a five-second project: use only two keyframes, and no expressions.

  33. Karri on April 9, 2010 said...

    Hey,

    I made this when I started to poke around in AE – http://vimeo.com/6488109

    It’s very basic, but nevertheless, tell me what you think!

  34. MarcyVF on April 10, 2010 said...

    Good to see some crisp Ae tuts again :) Been a long time.

    Where did your white bright layout go??

    Thanks!

    The Gorilla

    I had the bright layout when my screen was my only light for my screencasts. Now that I have some other lighting, I made it dark again.

  35. Tommy Vad Flaaten on April 10, 2010 said...

    Sweet! It’s cool how easy it can be to make something look professional and very awesome. This made me want to create more slick, original, simple effects! Great tips, great result and great motivator! Thank you!

    The Gorilla

    Glad you liked it. Thanks for watching, Tommy!

  36. marsio on April 14, 2010 said...

    anyone has ideas or link to nice animations with dots?

  37. Nicholas Patten on May 22, 2010 said...

    Hey Nick,
    Great tutorial. Here is what I ended up coming up with.
