    Walid' sketchbook|next step : walk cycle !

    Hi all !!! So I start an animation's sketchbook I'm really at the beginning of my learning, and I hope you will help me to improve. Instead of posting them in the sketchbook session, I prefer to post my exercises and assignments to have more critiques. Oh, and I'm a self-taught, I'm using the richard williams' book I'm also using tvpaint software to to my animations, but I'll maybe switch to the lightbox and pegbar to make my stuff ! And if you have any exercises, assignments, or advics, you're more than welcome So here are my first 2 exercises, I was focusing on timing and spacing, and I find there is a little issue with the ball, the movement looks a bit weird :

    The box holds the mass well. Nice job.

    I think the circle needs more tweens. It is pretty stroby.

    The ball when it's leaving the right side seems like it speeds up on it's first frame.

    I think the timing is off on the first one. That is a long way for the ball to fall in that amount of frames without tweens. I would say that is a great start and do a bunch more.

    This sketchbook will soon be a bitch to load, and that might screw up the timing in your gifs, but other than that, good animation studies! The box has a real feel of dimension in it.

    Keep studying from Williams! This part of CA really needs more threads like this.

    so a just something I thought to share is with the ball falling, you shouldn't forget that the ball is already moving before it enters the screen so there it moves a lot faster in the start and doesn't have a fade in like that.
    Nice job by the way.

    Bai Fan : thanks for your help !!

    BubbaGump : Thanks !

    icarus2912 : Yeah it looks weird I did that like the bal just falling without any forces on it ( i hope you understand , a kind of " free fall" " but in that case, the ball doesn't have to move forward, so eah, i sucked up at something, and did the same mistake for this one, I will fix it next time ! Anyway, thanks for your help !

    So here is my bouncing ball. it looks a bit better in timing and spacing, but it still sucks at something, it look like the ball stay much longer on the air each time, but whan i delet some frame, it fall too faster ! Hard to find the perfect timing and spacing !! I really need to update more often this sketchbook !

    hey walid; so this is where your hiding huh?
    good to see you about. and good start for animation.
    your making one very common mistake on your ball though;
    (thanks for the lines on the last one btw. as its impossible to watch this stuff frame by frame its a little hard to figure out the problem sometime.)
    you have to remember that a ball's forward motion is constant (or, slows down with a constant amount of friction)
    only the up/downward motion is speeds up and down kwadrantadly. (is that a word? change(velocity)V= (velocity)Vx9.8 I think..)

    ashess : Thanks for your help ! I just followed your advices, it's really better, maybe it needs a bit more tweens, but now the biggest mistakes are my arcs, the movement doesn't looks natural because of arcs, they looks crappy ! i'll take more time on them next time !

    I've watched a number of people learn the basics and it's always fun. Keep at it.

    ye my example isnt too clear on that part; but it's just a case of making the curve more parabolic; ie make the fall diff between the 1st 2 frames= 1 mm, make the diff between 2&3= 2 mm, the diff between 3&4= 6mm, the diff between 4&5= 42mm.
    this is not the right formula mathematically, but works in practice:
    (newspeed)=oldspeed+(oldspeed x oldspeed)

    That's pretty good. I like how the ball is streched, squished, and speeds up and slows down when it's supposed to. Much better than just a moving circle.

    You should try some more complicated stuff.

    Some nice stuff starting to happen here. These are the same exercises we started with on my course (I started a Digital Animation Degree before Christmas). We next moved onto making a cube person jump (looking at anticipation and overlap techniques).

    Remember to keep an eye on the volume of the ball in each frame. It may only fluctuate slightly between frames, but it makes a huge difference to believability.

    Only little things I notice that are off, but I won't preach - they are probably better than mine were! I'm more of a 3D animator, drawings frames on paper made me go insane. Though Flash is fine.

    Keep it up!

    P.s. - is this a personal thing or are you being taught it?

    Black Spot : Thanks man

    ashess : Wow, quite dificult to understand, but i'll try to think about it !

    oblivion_dragon : Thanks man ! I don't know if i really can do more difficult, i prefer doing this kind of stuff ( and i read the post of batcustard, with great advices, so i'll follow what he said ) !

    Royzy : Thanks man ! Yeah, the volume of the ball sucks, need to take more time, and to clean the lines ! Haha, i also wanna be a 3D animator, but i enjoy doing 2d animation ! For now i'm learning by myself, but i hope i'll enter at supinfocom next year, it's an animation school !

    Well, it's been a while that i didn't post here, i was really busy, so i might post a new animation today, or tomorow, anyway, i'm studying it again !

    this doesn't work for everyone: make noises with your mouth while you plan out the timing, I also like to move my hands around. Try to know what you are trying to make before you draw it. If it looks wonkey in your head it will probably look wierd on paper.

    Your timing is a little even, remember how much the ball is speeding up on its way back down too. You wont feel the impact unless its farther away the frame before it touches the ground. I usually give myself two frames to warp it into the squished ball.

    anyways, just vary your timing up a little more, and don't watch the study over and over too many times in a row. The ball will hypnotise you and start to look perfect.

    Thanks batcustard for your comment ! I tried to make noise but it didn't work for me

    well, i did a pendilum in perspective, i feel the weight but perspective sucks will give a new try at it tomorow

    I don't know for you guy, but the animation is runing really fastly, i export it in 12 fps though

    Try doubling your frames and putting it at 24fps instead of setting it to 12fps. This will also give you more options for timing later on. This will also stop files from going weird as a lot of movie players default whatever movie they have to 24fps. Typically it would turn a 12fps file into a 24 fps file with all the frames doubled but I guess it failed to do that this time?

    The only thing I see wrong with the perspective of your pendulum is that it's not swinging back enough. It looks like it's hitting a wall that it gets stuck on for a moment just past the middle mark. it needs to continue it's curve upwards. This means that the string/stick will actually appear to get shorter again as it moves past the middle mark (lowest point of the swing) away from us. Right now it's only a half swing.

    Your cushion as it reaches the high point before swinging away from us is nice though

    It looks like your really trying to think about the weight of the object and thats good. Pengilum swings in perspective are usually lose momentum in a spiral either starting at full swing in a circular motion or slowly making thier way through the degrees like like the second hand on a clock. "Up, down.. a little to the left. Up, down." anyways Try to do it without perspective first, the long way is always the short way in animation.


    If you have watched it five times, get back to work, or do something else for a little bit.

    most people only learn from second and third passes, the first one is just the archetecture.

    Hmmmm....I've got two words for you. Motion blur! Look up some techniques on how to do this in 2d. It will help you blend your frames, so they look more real and less strobe-like.

    Hi Walid,

    Hah, so much detail on just a swing. Gotta love it
    Someone mentioned the swing isn't complete. I think that's true: one more swing back and it's good. Also: the midpoint or center of the string shifts on the first and last frames. That's affecting the movement ofcourse. Keep going, man (y).

    Best wishes,
    Jan van der Zee

    hey buddy, i just joined this forum a week ago or so. i'm a pro 2d guy and i'm more than happy to help you out with your studies. Dick Williams book is a great place to start. i'll be looking at your stuff regularly and try to give input where i can. based on what i've seen you definitely MUST work at 24 fps. stick to shooting on 2s and 1s for now. i have 2 tutorials that i've written over at kirupa.com on the principles of animation, they may help you as well.

    hey Walid,

    Great stuff man! its fun to learn animation isnt it On the pendulum, I would ad more inbetweens on the end points.. so that it slows down at the end of each swing.

    Heres a fun exercise (at least I thought it was fun ): try animate straight falling balls made out of different materials: water / glass/ metal/ etc.

    I like your stretches and squashes for the bouncing ball.

    So when are we gonna see the "c" ans "s" curve tail?

    Keng : thanks for your help, yeah, next time i'll try to animate in 24 fps !

    rattus : Thanks mate !

    batcustard : Thanks for your good advices ! Yeah, i'm def back to animation, and will do my best to improve in this field, so yeah, will animate a lot and will follow your advices ! thanks

    someynguy : haha yeah, motion blur ! richard williams talked about it in the book, but didn't pay much attention, will read again this part thanks !

    jvdz : Thanks ! Yeah, for the pendulum, it's not that the swing is wrong, it's that i placed the horizon line too low on the animation ( i did a drawing to explain what i did ) but anyway, i learned from my mistake, so it's cool !

    DanielBodinof : Thanks mate ! yeah, animating in 24 fps looks good, the only thing is that i dunno how to double my frames in tvpaint animation when i set up a 24 fps animation, so i have to draw each frame twice, and it takes time ( for now it's only bouncing balls, etc, but in a few time it will be characters, and it will seriously piss me off to fraw each frame twice ) Anyway, You're always welcome in my sketchbook to give criics and to give me motivation !

    Cheeseitnow!!! : ooooh thanks man !

    sir Applejuicer : Haha, yeah, great fun to animate, i'm already excited to animate basic stuff, i'm looking forward to animate characters !! i'll try your exercises soon For now, i'm taking any exercises you would submit, i just wanna improve !


    HunterKiller_ : thanksss buddy !

    shamandalie : oooh girl, i'm glad you posted on this thread, i did a tail animation especially for you ( well, i'll do a new one for you soon, because this one sucks )

    Here is my stuff : the correction of the last animation, and the tail's animation ! i find there is no tweens :/ and the movment is wrong ! Anyway, Now that i have free time, i'll do an animation everyday
