  • hi I'm Ben Marriott I make weekly motion design and animation tutorials and this

  • week I'm starting a new series where I'm going to break down every single

  • transition in that animation this week the first transition

  • all right this project is available for download down in the description for you

  • to dissect further I made this project after going on a plug-in diet where I

  • stopped using plugins that helped with easing so I could focus on really

  • getting comfortable in the graph editor and that was probably the time where I

  • felt my animation skills improved the most so I built this animation a lot

  • around sort of really snapping eases and sort of smooth transitions just to

  • really try to push myself to my to my limits at the time

  • I summed up by making all the illustrated elements in Illustrator which is really only the mug

  • and the jug the mug I'll duplicate and the coffee bean as well for reference the

  • circles and those elements were easy enough to make in After Effects just using the ellipse tool

  • for part one of this project breakdown we really are only

  • gonna focus on this first transition here so we're going to break down this 1

  • second of animation in excruciating detail now let's dive into our black cup

  • pre comp and the first thing you'll notice when we get in here is that it's

  • all in grayscale it's in black and white that's because they're doing all of the

  • color correcting and adjustments when the adjustment layer at the top of this

  • comp called color the 3 effects I have on this adjustment layer are CC toner which

  • creates a kind of a gradient map that allows you to map selected gray values

  • to specific color values and because this is straight up brown across the

  • whole thing I could have achieved a similar look by using the tint effect or

  • tritone I like to use CC toner because it gives you a little more variety to

  • the shades save you on this really light brown area to be a little more saturated

  • you could do that if you wanted or desaturate it it's very easy to adjust

  • and it gives you a lot more control and the hue in the saturation I just sort of

  • amping up the contrast and the saturation and in this first section

  • both of these coffee cups have pretty much the same animation with these

  • there's one on the right the lighter one just having some extra sort of milk and

  • the jug added to it so I decided first to animate the cup on the left and then

  • duplicate that and add the extra stuff to the one on the right after I was

  • finished with it so let's dive into that first cup so here's what we've got

  • inside that cup pre comp we start off with our static mug the coffee being

  • splashed in the coffee cup rotating so we get a sort of top-down

  • view and then transforming into this sort of circling dot which would be

  • one half of the Ying Yang symbol that it forms I'm gonna get into

  • detail on the splash animation in a later video because that is part of the

  • last transition of this loop so let's start the work area just after that

  • splash settles and let's shy this layer so they don't clutter our timeline

  • the main layers we got here is this coffee which is the liquid from a side

  • view matte for that liquid cup lines which is the outline of the cup and handle

  • this yin-yang background which is the circular form from the top view the

  • coffee top which is the top surface of our coffee and the top of the cup here

  • which scales down from being aligned to the full circle I started by animating

  • with the cup top because it is the simplest single element that once it was

  • animated to my satisfaction it would give me some of the most information

  • about the animation that I could use to help me sort of make and inform

  • decisions and have a speed and parts of other shapes of the animation let's all

  • of this so we can just concentrate on this element I also started in Reverse

  • so I have this circle drawn here and its size is 400 by 400 pixels and then I

  • keyframed it with one axis of the sides moving down to zero now I didn't use a

  • scale property to do this and I'll show you why if we bring up a scale property

  • keyframe it unlink it and if I drag down one axis of the scale it is the same

  • sort of action of making it thinner but the stroke width would also gets scaled as well

  • and you get stuck for this sort of hideously looking a variation between

  • the line width which I almost always hate and what the time you get to zero

  • it's not even visible anymore so that would defeat the purpose of what

  • we're going for so let's undo those in the size property does the same things

  • the scale would do but it keeps the stroke width the same without having to

  • use any fancy expressions now if we're going to the graph headed up by

  • selecting these keyframes clicking here let's make some more room for this

  • you could see we've got a fairly strong ease out and a much snappier ease in and although I

  • animated this layer first to set the speed for the rest of this section I'm

  • still going back and fiddling with easing now and then once more elements

  • were animated simply try out some different speed options the next thing I

  • animate was the cup lines layer again here you'll see that it has two paths we

  • have one which is the handle of the cup which makes up a main body of

  • the cup and I also have in pink here a mask and that's just a mask

  • subtracting out this top line here because we're making that with an

  • ellipse tool that we've already animated now the outside path of the cup which is

  • the bottom one here is animated with only two keyframes so I keyframed its

  • first position which is a side of the cup and then in

  • about ten frames when our ellipsis is a full circle I have adjusted these sort

  • of anchor points to match that circular shape that's all the animation I needed

  • to do for that path I also use it a plugin called ease copy which is

  • completely free and one I covered in my top free plugins videos so I can simply

  • select the keyframes from that cup top ellipse layer and select copy from these

  • copy overhere and click paste these which copy the ease exactly from those

  • from the size property to this latest path property this cap handles a few

  • more keyframes because it has more curves and when you keyframe between two

  • paths positions each of these individual anchor points here or moving the

  • straightest path between the two keyframes and that can cause the Bezier

  • handles at each point to go a little strange and unpredictably in that

  • movement so I've just added some extra keyframes along the way to keep them on

  • the right path until the end of this transition I was kind of drawing them

  • frame by frame which is sometimes just the quickest way then we have our coffee

  • layer down here which is a black rectangle using this above layer as an

  • alpha matte this liquid matte layer is essentially a copy of our cup lines

  • layer just scale down a little bit and giving it a fill as well so it'll matte

  • out just this internal section which means that coffee liquid layer will stay

  • confined to this pink area of the cup then we have our coffee top layer which

  • is essentially a duplicate of our cup top layer which is an ellipse scaling up

  • with a size property and have its position just moving slightly upwards as

  • well so it ends up in the very center of that circle and that just gives a little

  • bit of extra parallax during these two frames while it's in transition

  • I'm also animating the scale property of the shape as well so when it gets to

  • this top-down view it's going to continue scaling up very gradually to

  • fill up this entire shape and then quickly scale down and reveal this yin

  • yang background that we've got now if we look at this scale property in the graph

  • editor you see it's scale starts at 100 and then creeps up very slightly until

  • it reaches its peak here and then just quickly sort of accelerates and scales

  • down really fast and during that scale down is where we have this cup handle

  • disappear as well you can see I've got a couple of key

  • frames with its path just sort of shrinking into the mass of the cup if

  • you need to get rid of any elements in a transition you're doing it's great to do

  • it during the fastest movement where your eyes being directed towards another area

  • there's a go frame-by-frame you can see how this path sliding in very

  • slightly towards the cup but because this movement is so fast and dramatic I

  • think we could even get away with just cutting away from that handle

  • and not having it transitioning inwards at all so there we have one cup rotating in

  • faux 3d space now let's go into the composition for the other cup which has

  • all the milk and the color changes inside this composition was an exact

  • duplicate so it has the exact same animation with some additional elements

  • added this milk jug here is just that pass that we've imported it from

  • Illustrator and the only animation we've got on that is its position values and

  • its rotation that way we've got it sort of swinging from the right pulling up at

  • the same time it's rotation is sort of making this top line sit absolutely

  • vertical as it exits out the screen and then we've got our milk pour main layer

  • here which is parented to that jug now this one in particular can be done a

  • variety of ways in After Effects and because this project is two years old

  • I'm not exactly sure that this is really the best way to do this but I have this

  • anchor point attached at the very top here it scales all the way up to 200% as

  • it gets longer so I'm increasing that scale to make it pour down into the cup

  • and then when the jug releases it I have its position sort of moving downwards to

  • fall into the cup and then I have this mask here making it disappear as it

  • enters with a nice rounded edge and I've got these two layers on top and this

  • first one is a circle with a mask to create this sort of rounded edge as the

  • milk pours and the second one is a small circle for a rounded cap to this sort of

  • milk pour which sort of follows the downwards into the coffee now this

  • section in particular looking back could have been done a lot more effectively

  • with maybe just a single shape layer and animating the path every few frames

  • I think striving for efficiency is great I'm certainly much more of a stickler

  • for that now than when I animated this but the result is really what counts in

  • the end sometimes you've got a hack a few shape layers together for a few

  • frames just to make it work and I think that's completely fine if you do that

  • and then I've got a duplicate of that layer called a milk pour in coffee which

  • is exactly the same but for when it appears inside the coffee which is just

  • as the darker fill on it and I've got a lighter coffee in coffee layer down here

  • which is sort of the milk as it appears inside the coffee and sort of has this

  • gradient as it pushes upwards now this took me a few times to get right

  • originally I had the gradient coming outwards from the top of the pour here

  • which seemed intuitive at the time but it just really didn't look right so

  • after watching some reference and kind of thinking about what was wrong with it

  • I discovered that you know the coffee is gonna get lighter from the bottom up as

  • the milk sort of settles at the bottom and then dilutes upwards so to animate

  • the milk rising I think I have this mask let's change

  • the color to something pink so you can really see it and that sort of Rises

  • from the bottom and I just have two keyframes on that Matt's path and it

  • goes from the bottom here right to the top and also animated the feather on

  • that mask as well so it's a lot more feathered as it starts diluting and less

  • feathered when it's just first poured into the coffee here I've also added

  • some keyframes to the fill effect here so it starts off being pure white and

  • then as it gets more diluted it becomes gray until the whole thing is this gray

  • color here also apply to fill effect to our coffee top layer here so that fades from

  • black to white as well now those little elements like the changing of the the

  • fill and the gradient and where they are the coffee rises up from those aren't

  • all essential elements but I really think that they add a lot to the

  • animation they were by far my favorite things to animate and when looking back

  • on it now those are the little touches that I like the most and I think they

  • really help sell the overall animation and here's what both cups look like an

  • action I've also keyframe the position of both

  • of these comps here so the white comp moves down and the black column moves up

  • so they end up diagonally sort of opposite facing each other and here's

  • what they look like in context of the whole animation

  • and that was a long time for me to explain one-and-a-half seconds of

  • animation now you can see why I'm breaking this up in two parts now next

  • time it may not be next week I'm probably gonna do a few more tutorials

  • in the meantime before we get back to this project the next time we do I'm

  • gonna cover this yin yang transition that we've got going on here but if you

  • can't wait until then this project file is available for download down in the

  • description now if you use any techniques of processors from this video

  • please tag me on instagram at ben_marriott_ because

  • I'd love to see what you make please let me know down in the comments if you'd

  • like more of this series where we go in-depth into a very specific very

  • detailed minut the minutiae of an animation I'd love to know you think

  • please don't forget to subscribe hit the bell icon share and like as well thank

  • you I'll see you next week
