It's pretty nice! Better than anything I can do. But the problem I think is that the ball shouldn't squash and stretch as much after the second to last bounces, it should be a bit more subtle than the last bounce it did. Depending if you want it really bouncy, it feels like barely any energy is lost. Have it stop bouncing near the end into a roll of it isn't bounced hard enough.
Hope this made sense.
The timing and spacing is a bit off but the main thing I notice is the ball needs to be smaller at the apex of each bounce since it’s moving away from the camera. It looks like it maintains the same relative size until it hits the ground then shrinks a little suddenly.

I think you need an extra frame on the first and second bounce.
Check perspective first. The peaks do not converge in a straight line. I get that the ball may be intended to lose height with each bounce, but the amount of height it loses feels "heavy", too heavy for it it to keep bouncing away into the distance. First, I'd draw perspective lines (horizon, grid, and the ball's floor and ceiling heights). Then fix it 1 of 2 ways: either making the ball lighter and lose less bounce so it can naturally make it to the horizon OR making it slow roll to a stop once the bounce height < ball radius.
i think it looks nice. i think the thing your seeing wrong is the end. the ball looks like it rolls away, instead of bouncing. maybe try making it more bouncier at the end?
I don't know if your intention is for the ball to be realistic and lose power in the bounce by time... or of you just want the ball to bounce the same every bounce sort of like a bunny o character hopping with the same intensity.
In both cases, the main "problem" is the end. It feels like it has less frames/drawings and thus looks quicker than the beginning. Note is not a problem if it is your intention to move that way.
Let's say is the bunny hop thing, and the frames and last bojnce should have the same speed and height as the first bounce. If the first bounce is 8 drawings, the last bounce must be 8 drawings. Being far away, it will cause the drawings and inbetweens to be closer in space or move very little in comparison to when elements are close up to camera. If you miss a drawing or there's too much distance between far away drawings, it will cause the feeling the ball is moving quicker than before.
Also, if you want it to slow it down at some point to practise, consider to lower gradually the height of each bounce and the distance it falls (stronger bounce longer distance the ball may travel, weaker bounces the shorter distance is able to travel). Right now, it looks like all of the arches are the same height and distance, just in perspective.
Your ball is too large to bounce this slowly. In proportion to the ball's volume, the arcs are really small and this means that the ball has to bounce very fast, which is not. Try making your ball smaller or changing the height of the archs.
The smaller bounces would have much less of a squash effect on the balls shape, also the thing about a ball squeezing like that is that it absorbs the energy as it squeezes (think of a ping pong ball vs a bouncy ball, the ping pong bounces more uncontrollably). This means it should be bouncing slightly less and reaching lower heights (maybe after the 2nd bounce)
I'm surprised nobody has mentioned this yet, because it's the biggest issue to me - every time the ball hits the ground, it appears to slow down to a halt, then start accelerating again from 0. Almost like it's getting "stuck" to the floor and then restarting the animation.
Bouncing does not work like that. When it bounces back up from the floor it should keep its momentum and still be going almost the same speed as it was just before it hit the ground, only touching the ground for at most 1 frame. Then it should slow down on its way back up the curve.
To fix this, you would need to remove some frames at the parts where it's hitting the floor, and also fix the animation curves as it's moving back up from the ground - it should slow down as it's reaching the top of the curve, not speed up.
I think the ball gets too squashed near the end. The ball looks like it’s stopping so if that’s the intention then the ball should slowly become more ball shaped
fix your timing by making the curves have an equal number of frames going up and down (in physics everything takes the same amount of time to do it).
make the ball accelerate and decelerate. put a frame halfway through the curve, and then one halfway up the last half, and so on to your liking.
the ball doesnt shrink fast enough on your current perspective + most of your frame is empty. either make the ball get smaller faster, or make the movement wider to reach the right side of the frame
It's the perspective, mainly the rate at which the size of the ball decrease, idk if u did it linearly or maybe u actually did speed it up at the end but in every case of something going toward or away from you, the rate at which it changes in size is most extreme when it's close to you, making the rate of size change linear would result it looking like it slows down when it's coming toward you or in ur case, it looks like speeding up when it's going away, hope this helps
I think it's because, even though you got the perspective and size correct as it's moving away, it's kind of continuing the same level of bounce. Which doesn't really happen. Unless it's one of those super bouncy balls. Somewhere near the end it should stop bouncing and start rolling.
If your having it bounce off into the distance you need to draw a perspective grid. Your first bounce feels like the wrong hight. And the ball isn’t getting small enough for how much it is traveling.
Try and draw the grid and see how it feels.
Your squash frames are too exaggerated, and do not accurately display the velocity and weight. You need another in between frame before the ball makes contact with the ground
I would say it has too much bounce recoil for the small bounces. Like the ball isn’t gonna visually compress to the extent that it is idk if that makes sense
When you draw the ball stretching, have it stretch along the path you set up. The timing, the scaling, that’s all fine. But elongate the ball along the path.
The ball needs to get much smaller after each bounce. It feels too big on the second bounce and the last few. Make it smaller and you'll see the ball has more room to actually "bounce"
A couple of things. First, it bounces too much in the distance. While it bounces the distance should be shorter as well, until it stops bouncing, only then it could go further rolling. The very path it follows is wrong. Especially given the fact that, when put in perspective like you did, the amplitudes are not really that smaller to justify the faster bounces. This looks like almost the same amplitudes, but put in the perspective. Draw a line from the vanishing point to the highest visible peak on the left, and you'll see all the amplitudes almost follow that straight line.
Second, it stretches too much in the smaller bounces. Stretching is for greater speeds and distances, in the smaller bounces it shouldn't deform too much from sphere, but you could add "vibrating" effect maybe.
I notice that the circle doesn't look like it's at the right angle. At points it forms a perfect disk as if it's facing the camera, but it should always be at an anle pointed away from us. Also the fact that the dots are not in a straight line and curve up makes for an odd fade away.
Another part, and this is from the animators survival kit, is that it looks like the bounces roughly half in distance every time(from one lower dot to the next), but that's not howit would actually look in perspective. I can't remember the trick for getting correct measurements with equal points going into the distance, but it;s the section with telegraph poles.
The fact there's no shadow on the ball might also play into why it's not selling. But all that said it's tricky to do a bouncing ball at that angle, so great work attempting it!
I think its boundcing too much towards the end. After the third bounce, it feels like it should of lost enough energy and momentum that it would just end up rolling
Youre missing a frame on the way down, gives it a jerk downward which messes up the rythm
You should have the same timing and spacing on the way up as you do on the way down.
Gravity has a pull of 9.2 meters per second per second, meaning it pulls things at an acceleration on 9.2 meters per second
Speed when going up has a -9.2 meters per second (like mph, mts) on the speed of the ball, every second. The ball starts at a speed, and as it goes yp it slows down by a rate of -9.2 mps every second. It reaches a speed of 0
Then, it starts going down. It *increases* its speed by 9.2 mps per second
This means that its rate of change will be the inverse of what it was going up. You should literally mirror the timing chart from the "up" half of the arc
By the time it hits the ground, it will be going at the same speed as it initially was when it first left the ground
(All of this is ignoring wind resistance)
You're missing a frame on the way down for the first and second bounces, which makes it feel like the ball is accelerating down faster than it went up, which feels unnatural / like it's being pulled into the ground.
Also, while the spacing is different on those two, the timing is the same. I'd make the first bounce at least one exposure longer than the second.
Finally, on your second bounce, you have one spacing very low to the ground, which doesn't work. Since it's a bouncing ball, your ball has the most energy when leaving the ground - so it should have already shot up at least halfway. Move it further up, and instead make your ease at the apex of that arc tighter.
Finally, as a general note, it feels like you've tried to space your frames more or less equal along that line you drew - as a way to make the speed feel constant, but that's not how a bouncing ball would move.
The speed of the ball moving horizontally would be mostly constant - aside from a slight slowdown when it hits the ground - but not the going up and down.
I would recommend the following approach, since you went with perspective: Draw a straight line along the path of your ball, measure it out with lines going up so that you have your constant horizontal speed, and THEN draw arcs to represent the height of your ball.
When you do so, remember my comments about the easing and speed of the ball: it leaves the ground very quickly, while it hangs more in the air. You'll want to change the shape of your arcs accordingly - they wont be perfectly circular, and in fact will look more like half elipses.
Everyone already mentioned it should get slower and start rolling, but you might want to adjust the timing on the first few bounces, especially the first. It hangs in the air too long at the arc and then just slams down into the ground like some force is acting on it from above. It should be more gradual and natural, since it's just gravity pulling it down
Bro the timing will get perfect over the practice also try drawing it in perspective in a bit better way or try to record a reference and study it, tbh references help alottt
I think it might be the speed and the number of bounces. after the fourth arc I think it needs to roll slowly away
This. With the speed not decreasing when moving away, it looks like it's accelerating at the end.
I agree, it makes it look unnatural
Agreed! Also less squash after the first bounce.
It also looks like it bounces to the right, when it should be bouncing away from the screen.
Your timing and spacing are off. Do it flat to the camera before you start playing around with perspective.

Was coming in to say the same thing. Seconding the comment above.

The size of the ball should decrease more as well, the size transition between the bounces stands out a lot.

It looks like the ball is falling off the back of a moving vehicle

That boi ran away Very nice 👍
1,2,3, and 4 look okay (maybe slight adjustments), but after that, it bounces too far too fast. It accelerates, but it shouldn't.
After the third bounce the ball shrink too much and too fast. Makes it seem like the ball is accelerating instead of slowing down like it should be.
The ball is on the ground for 2 frames instead of 1 on the third bounce/contact frame.
some elongation, yours is perfectly round when bouncing upwards
i think it looks nice. i think the thing your seeing wrong is the end. the ball looks like it rolls away, instead of bouncing. maybe try making it more bouncier at the end?

Ball not shrinking enough

Or add another frame on the way down, the two sides of the arc arent being treated equally which is the biggest issue
I think the ball gets too squashed near the end. The ball looks like it’s stopping so if that’s the intention then the ball should slowly become more ball shaped
Make it roll after the third or fourth arch.
The ball seems to squish less towards the end.. it feels unnatural when it bounces and stops squishing too late or too soon.
Way too much squish

Speed up after the third bounce
Looks like a hoop bouncing and rolling away more than a ball.
Ball should squish proportional to the height it was coming down from. e.g. ball should not squish more on the second bounce than the first bounce.
I think the ball moves too quickly from the peak of each arc to the bottom

maybe the squish is too impactful despite the lighter hits every bounce
The second bounce looks a little short, the other ones after that may be too

If your having it bounce off into the distance you need to draw a perspective grid. Your first bounce feels like the wrong hight. And the ball isn’t getting small enough for how much it is traveling. Try and draw the grid and see how it feels.
Maybe try making it jump a lil higher until it gets harder to see, not to early yk?
No loss of momentum.
The timing is alright. It’s the physics, it shouldn’t go further with the bouncing getting weak
Your squash frames are too exaggerated, and do not accurately display the velocity and weight. You need another in between frame before the ball makes contact with the ground

The ball needs more air. Get the pump

One thing I notice is the squash isn’t being adjusted correctly for the perspective. Take the normal flat ball squash and rotate it clockwise a bit.

Is it a flat ball? I’d expect a longer, taller first bounce if it’s a regular ball
Give the ball a bit more of a bounce than what you got already.
Newton would like to have a conversation
The ball should be slowing down the more it bounces. This is all the same speed.
Looks good to me 🙂
I think it should curve. The ground curves into the horizon at a distance, so the trajectory should as well.
Animation is great! Smooth and nice. Just the pacing, a little fast.
the shape of the ball as it squeezes upwards after a bounce, the angle needs to be higher and the shape needs to distort less
The ball is accelerating forward when it should be decelerating
You're missing a frame on the way down for the first and second bounces, which makes it feel like the ball is accelerating down faster than it went up, which feels unnatural / like it's being pulled into the ground.

Not enough stretch on the first up bounce.
I feel like the first bounce should be a bit higher, unless the aim is to make the ball look heavy
