That means how many frames should be one second of animation later on. Right now it's set to 24. Make sure to change this according to what you want to have. In most cases the standard FPS is 25 frames per second which I would recommend. But if you have a video with 60 FPS, certainly you can also change this accordingly. Then in order to animate something, we need the timeline down here, which is like the basic editor for animation. If I click on this button to change the editor type, you can see under animation, we also have a bunch of other editors. Doing this chapter, we will take a look at the timeline, the graph editor and the dope sheet editor because these are the ones you will use the most. So now let's animate the transformation of the cube. Our pointer is at frame one. You can left click and hold and move it around to change the frame, basically the point in time. Let's move it over here. Now let's grab the cube here by selecting this, press G, move it to the side. And now we basically save this position in time by right clicking and then click on insert keyframe or simply press I, which I do from now on, simply press I. And now we can define what we want to save at this point in time. For example, the location, rotation, the scaling or combinations like location and rotation, location, rotation and scale, location, scale and rotation and scale. But for this example, let's use all three of them, location, rotation and scale. So I click on that. And now you can see down here, these yellow dots were added. If I press Alt A to deselect them, they are white. So these are the keyframes. And if you're now wondering why we have so many of them, if I open this up, they are even more. But what this all means, we will learn in the timeline video where we also take a closer look on how to edit keyframes. But in a nutshell, you can see we have single keyframes for XYZ location, XYZ rotation and the same for scaling. And then we can basically edit each individual keyframe for each axis. But yeah, more about this later. Now in order to create an actual movement here, let's go further in time, maybe to frame 50, which would be two seconds with 25 frames per second. And now let's press G, move it to the other side. And since we also animated the rotation and scale, let's change the rotation by pressing double R and with S the scaling. And now let's press I again and then click on log road scale again to add another keyframe for location rotation and the scaling. And now comes the magic because Blender automatically interpolates these two keyframes. So we have a fluent animation if I play back the animation between these two keyframes. Let's set the end frame here to 60. And if I now play back the animation with this button here or by hitting space you can see it's now starting over and over again. So and certainly we cannot only add two keyframes we can add as many as we like maybe here in between. Let's add another one by changing the values press I, Lockword Scale and now this is also included in the animation. So and certainly you cannot only animate one object, you can animate as much objects as you like. For example, let's animate the rotation of this spot lamp, press R, Z for the Z-axis, move this over here. My pointer is at frame one, press I, and then I wanna animate the rotation. Let's go over to frame 50, press R for rotation, lock this along the z-axis, move this over here, press I rotation. And now I have animated two objects. So, and we cannot only animate objects in 3D space, we can also animate properties like for example the color of the cube or the strings of the spot lamp here, but how this works we will learn in the next video.",
