We asked to explain how to change speeds We asked to explain how to change speeds of orbitals. Um, so for simple orbitals, of orbitals. Um, so for simple orbitals, of orbitals. Um, so for simple orbitals, it's actually quite simple. You just add it's actually quite simple. You just add it's actually quite simple. You just add some additional key frames. I'll show some additional key frames. I'll show some additional key frames. I'll show you what I mean. I'm just going to pan you what I mean. I'm just going to pan you what I mean. I'm just going to pan around around around this box corner. So, I'm looking at this corner So, I'm looking at this corner there. Adjust my focus. Out of cartisian control to rapidly Out of cartisian control to rapidly adjust my focus back. So, I'm just looking at that point. So, I'm just looking at that point. Zoom a bit. go. I hope you can see that more clearly go. I hope you can see that more clearly now. Okay. now. Okay. now. Okay. And And And my minimum focus. Okay. Don't need to be my minimum focus. Okay. Don't need to be my minimum focus. Okay. Don't need to be it then. Just move back a bit. just just focus focus focus just on that corner. There we go. Okay. just on that corner. There we go. Okay. just on that corner. There we go. Okay. So now I'm going to store this as my So now I'm going to store this as my So now I'm going to store this as my first key frame first key frame first key frame and then orbit it around it. Say this is my next key frame. Say this is my next key frame. Okay. Uh now it's doing a straight line Okay. Uh now it's doing a straight line Okay. Uh now it's doing a straight line between the two because it's not in between the two because it's not in between the two because it's not in orbital. So I'm going to change this to orbital. So I'm going to change this to orbital. So I'm going to change this to be orbital. So, we'll do a nice curve be orbital. So, we'll do a nice curve be orbital. So, we'll do a nice curve around there. Now, it's not happy. Let's around there. Now, it's not happy. Let's around there. Now, it's not happy. Let's just see why. Probably it's going too just see why. Probably it's going too just see why. Probably it's going too close body the rig. the rig. Why is it not happy? Let's just have a Why is it not happy? Let's just have a Why is it not happy? Let's just have a look. Oh, it's complaining about a look. Oh, it's complaining about a look. Oh, it's complaining about a gripper, which I don't have connected at gripper, which I don't have connected at gripper, which I don't have connected at the moment. So, I'm just going to go the moment. So, I'm just going to go the moment. So, I'm just going to go down here, down here, down here, open this up, and disable my gripper. We go. And it's now quite happy it's We go. And it's now quite happy it's ignoring it. So this is my move. Okay. And it's nice, but I want to slow Okay. And it's nice, but I want to slow it down the middle. So the easiest way it down the middle. So the easiest way it down the middle. So the easiest way to do that is to just insert a couple of to do that is to just insert a couple of to do that is to just insert a couple of key frames close to the middle. So one key frames close to the middle. So one key frames close to the middle. So one there, let's say, and one there. there, let's say, and one there. there, let's say, and one there. Now I've selected filter key frames. So Now I've selected filter key frames. So Now I've selected filter key frames. So it's basically there along the path. it's basically there along the path. it's basically there along the path. It's created some key frames go along It's created some key frames go along It's created some key frames go along the path. You can see them. And to slow the path. You can see them. And to slow the path. You can see them. And to slow it down, all I do is I either type in a it down, all I do is I either type in a it down, all I do is I either type in a number here or just slide this along. number here or just slide this along. number here or just slide this along. So, I'm just going to slide this a So, I'm just going to slide this a So, I'm just going to slide this a little bit further out. And what's that little bit further out. And what's that little bit further out. And what's that do? What that is doing is you'll see do? What that is doing is you'll see do? What that is doing is you'll see these points haven't moved. They're these points haven't moved. They're these points haven't moved. They're still in exactly the same position still in exactly the same position still in exactly the same position because these are the position. I because these are the position. I because these are the position. I haven't changed positions. So, they're haven't changed positions. So, they're haven't changed positions. So, they're exactly the same position on the path, exactly the same position on the path, exactly the same position on the path, but I've increased the time between but I've increased the time between but I've increased the time between them. So, I've kind of stretched how them. So, I've kind of stretched how them. So, I've kind of stretched how long it spends doing that little long it spends doing that little long it spends doing that little section. Okay. So, I'm going to just section. Okay. So, I'm going to just section. Okay. So, I'm going to just move them out a little bit more, move them out a little bit more, move them out a little bit more, get a bit more obvious. If I now run get a bit more obvious. If I now run get a bit more obvious. If I now run this, you see it kind of slows down, this, you see it kind of slows down, this, you see it kind of slows down, then speeds up again. I run it then speeds up again. I run it then speeds up again. I run it backwards, goes along, slows down, then backwards, goes along, slows down, then backwards, goes along, slows down, then speeds up again, follows the curve speeds up again, follows the curve speeds up again, follows the curve exactly, but all it does is change the exactly, but all it does is change the exactly, but all it does is change the speed. Now, that is one way of doing it. speed. Now, that is one way of doing it. speed. Now, that is one way of doing it. There is a slightly more advanced way of There is a slightly more advanced way of There is a slightly more advanced way of doing it uh that can be used for any doing it uh that can be used for any doing it uh that can be used for any type of motion that will change the type of motion that will change the type of motion that will change the speed along the path without affecting speed along the path without affecting speed along the path without affecting the path itself. But it is slightly more the path itself. But it is slightly more the path itself. But it is slightly more advanced. Let me show you what I mean. advanced. Let me show you what I mean. advanced. Let me show you what I mean. So let's delete these points. So let's delete these points. So let's delete these points. I'm going to delete Y and delete. Okay, good. So I'm back to Y and delete. Okay, good. So I'm back to my original move. same speed. Okay. And what I'm now going same speed. Okay. And what I'm now going to do is I'm going to go to view graphs. to do is I'm going to go to view graphs. to do is I'm going to go to view graphs. Okay. Now, this is a a grass view and Okay. Now, this is a a grass view and Okay. Now, this is a a grass view and you can look at different things like you can look at different things like you can look at different things like what each axis is doing, what the what each axis is doing, what the what each axis is doing, what the cartisian axes are doing. Okay. And in cartisian axes are doing. Okay. And in cartisian axes are doing. Okay. And in this particular case, I'm going to look this particular case, I'm going to look this particular case, I'm going to look at the speed profile. Now a speed at the speed profile. Now a speed at the speed profile. Now a speed profile graph is basically a graph that profile graph is basically a graph that profile graph is basically a graph that shows or doesn't show any speed. It shows or doesn't show any speed. It shows or doesn't show any speed. It allows you to adjust the the speed or allows you to adjust the the speed or allows you to adjust the the speed or the position along the path. So this is the position along the path. So this is the position along the path. So this is going from zero to 100 frames because my going from zero to 100 frames because my going from zero to 100 frames because my move is 100 frames long. move is 100 frames long. move is 100 frames long. And this is the current time and this is And this is the current time and this is And this is the current time and this is the kind of virtual time along here. And the kind of virtual time along here. And the kind of virtual time along here. And what happens is if I adjust this point what happens is if I adjust this point what happens is if I adjust this point and click on this to allow me to adjust and click on this to allow me to adjust and click on this to allow me to adjust this point. So let's say I pull that this point. So let's say I pull that this point. So let's say I pull that down. Okay, this means that it'll start down. Okay, this means that it'll start down. Okay, this means that it'll start off much slower. So if I look at these off much slower. So if I look at these off much slower. So if I look at these numbers along here, at frame 11, numbers along here, at frame 11, numbers along here, at frame 11, it'll only be at the real frame five. it'll only be at the real frame five. it'll only be at the real frame five. And at frame And at frame And at frame 28, it'll only be at frame 18. 28, it'll only be at frame 18. 28, it'll only be at frame 18. So allows me to adjust. Now, the reason So allows me to adjust. Now, the reason So allows me to adjust. Now, the reason there's a red graph and a blue graph is there's a red graph and a blue graph is there's a red graph and a blue graph is because one is the camera and one is the because one is the camera and one is the because one is the camera and one is the target. You can actually adjust the target. You can actually adjust the target. You can actually adjust the speed of the camera path and the target speed of the camera path and the target speed of the camera path and the target path. But just to keep it really simple, path. But just to keep it really simple, path. But just to keep it really simple, what I'm going to do is I'm going to what I'm going to do is I'm going to what I'm going to do is I'm going to press this button here, which locks the press this button here, which locks the press this button here, which locks the two. So if I adjust one, it'll adjust two. So if I adjust one, it'll adjust two. So if I adjust one, it'll adjust both. And I'm going to reset it so it both. And I'm going to reset it so it both. And I'm going to reset it so it goes back to a straight line. goes back to a straight line. goes back to a straight line. So reset this point. Okay. And now what So reset this point. Okay. And now what So reset this point. Okay. And now what I'm going to do is I'm going to insert a I'm going to do is I'm going to insert a I'm going to do is I'm going to insert a point. I can either type in where I want point. I can either type in where I want point. I can either type in where I want it or I'm going to just insert a point it or I'm going to just insert a point it or I'm going to just insert a point here in the middle. Okay. And then I'm here in the middle. Okay. And then I'm here in the middle. Okay. And then I'm going to adjust my control points like going to adjust my control points like going to adjust my control points like this. Now what this does is it basically this. Now what this does is it basically this. Now what this does is it basically adjusts the speed along the path. So adjusts the speed along the path. So adjusts the speed along the path. So here it'll actually go quite fast. Okay. here it'll actually go quite fast. Okay. here it'll actually go quite fast. Okay. And then it will slow down, slow down, And then it will slow down, slow down, And then it will slow down, slow down, slow down, and then start speeding up slow down, and then start speeding up slow down, and then start speeding up again. Okay. And in fact, you can again. Okay. And in fact, you can again. Okay. And in fact, you can actually make it quite wild. You can actually make it quite wild. You can actually make it quite wild. You can actually make it go like this, which actually make it go like this, which actually make it go like this, which would mean it would actually get up to would mean it would actually get up to would mean it would actually get up to speed, come to a stationary point here, speed, come to a stationary point here, speed, come to a stationary point here, go backwards along the path, come to a go backwards along the path, come to a go backwards along the path, come to a stationary point again, and then speed stationary point again, and then speed stationary point again, and then speed up again to the end of the path. But I up again to the end of the path. But I up again to the end of the path. But I don't want it to be quite so abrupt. So don't want it to be quite so abrupt. So don't want it to be quite so abrupt. So I'm going to just do it like this. So I'm going to just do it like this. So I'm going to just do it like this. So it's going to come almost to a pause in it's going to come almost to a pause in it's going to come almost to a pause in the middle. Okay. And the middle. Okay. And the middle. Okay. And this is my speed profile. Now it it's this is my speed profile. Now it it's this is my speed profile. Now it it's not going to use this unless I change in not going to use this unless I change in not going to use this unless I change in the job configuration the job configuration the job configuration my speed profile from off. And this my speed profile from off. And this my speed profile from off. And this selects what I want to speed profile. So selects what I want to speed profile. So selects what I want to speed profile. So I can I I can tell it to adjust just the I can I I can tell it to adjust just the I can I I can tell it to adjust just the speed profiling axes or the target speed profiling axes or the target speed profiling axes or the target tracking and what we refer to as master tracking and what we refer to as master tracking and what we refer to as master axes or all axes which let's say you axes or all axes which let's say you axes or all axes which let's say you have a turntable uh moving or um some have a turntable uh moving or um some have a turntable uh moving or um some other axis moving. It'll speed profile other axis moving. It'll speed profile other axis moving. It'll speed profile everything together. For simplicity sake everything together. For simplicity sake everything together. For simplicity sake I'm just going to say all. Okay. Apply. I'm just going to say all. Okay. Apply. I'm just going to say all. Okay. Apply. And now if I run this move, And now if I run this move, And now if I run this move, see it comes to a slow and then speeds see it comes to a slow and then speeds see it comes to a slow and then speeds up again. I'll run that backwards, up again. I'll run that backwards, up again. I'll run that backwards, speeds up, slows down speeds up, slows down speeds up, slows down and then speeds up again. And just to and then speeds up again. And just to and then speeds up again. And just to prove the point, I'm going to go to my prove the point, I'm going to go to my prove the point, I'm going to go to my graph view again graph view again graph view again and speed profile. and speed profile. and speed profile. Okay. And then I'm going to adjust this Okay. And then I'm going to adjust this Okay. And then I'm going to adjust this to be slightly more extreme. to be slightly more extreme. to be slightly more extreme. Let's say there. Okay. By the way, if I Let's say there. Okay. By the way, if I Let's say there. Okay. By the way, if I want to have this permanently on on the want to have this permanently on on the want to have this permanently on on the screen, um, what I can do is I can screen, um, what I can do is I can screen, um, what I can do is I can actually just insert it. Let's say I actually just insert it. Let's say I actually just insert it. Let's say I want to insert it there. You'll see want to insert it there. You'll see want to insert it there. You'll see there's a blue line that highlights there's a blue line that highlights there's a blue line that highlights between my top two views. You see that? between my top two views. You see that? between my top two views. You see that? So, that's where it'll insert it. If I So, that's where it'll insert it. If I So, that's where it'll insert it. If I do that, there you go. It's inserted it. do that, there you go. It's inserted it. do that, there you go. It's inserted it. Uh, I'm going to adjust these though Uh, I'm going to adjust these though Uh, I'm going to adjust these though because because because I want my camera view to be bigger. I want my camera view to be bigger. I want my camera view to be bigger. Okay. Okay. Okay. All right. So, this will actually get up All right. So, this will actually get up All right. So, this will actually get up to speed, slow down, stop, go backwards, to speed, slow down, stop, go backwards, to speed, slow down, stop, go backwards, then get up to speed again, slow, stop, then get up to speed again, slow, stop, then get up to speed again, slow, stop, and then proceed on to the end. So, and then proceed on to the end. So, and then proceed on to the end. So, let's run this and we'll see that very quickly. I'll slow it down a bit so very quickly. I'll slow it down a bit so it becomes a bit more obvious. 12 frames it becomes a bit more obvious. 12 frames it becomes a bit more obvious. 12 frames per second. per second. per second. There we go. So, speeds up, slows down There we go. So, speeds up, slows down There we go. So, speeds up, slows down to a stop, goes the other way, and then to a stop, goes the other way, and then to a stop, goes the other way, and then goes back along.
