Now up into this point we've been making constant speed changes. That is something's 200% faster or 50% slower, but there are times where you may want to vary the speed slowing it down speeding it up over time. You see this a lot in sporting events, you may see it in a romantic movie just as the couple is about to kiss. In my case I'm going to use it with the art of making pizza. Now, to get your head wrapped around it, we're going to look in a couple of locations within our interface. I'm going to load the pizza assembly clip back into our source monitor, and switch to the Effects Control tab, and I want a lot more space on the right side.
So I'm going to go ahead and click on this vertical line between my list of my effects and the actual timeline here, and just slide it over to the left. This gives me a lot more real estate to work with. I'm also going to open up the disclosure triangle for Time Remapping, and then under there is a disclosure time for Velocity. Once I have this done I'm going to go back to my timeline and do a couple of things. Now, you don't have to do this, but I want you to get a good sense of what is happening when I make changes in either the Effects Control panel, or in my actual timeline.
Now, to simplify things, I'm going to delete the audio. When you do any kind of a constant speed change, audio does slow down and speed up, and you can even in the speed and dialogue box check, change the pitch so people's voices more closely resemble what they really should sound like. But when you're slowing down and speeding things up, you really don't want the audio to do that. So Premiere Pro ignores the audio completely when you do any kind of variable speed change, and if I left the audio here it would be fine, it would play back but I would get little warning boxes to say my audio is out of synch. So I'm going to deselect both the video and audio, hold down the Option key, select just the audio, and delete it.
Now we can focus specifically on our pizza assembly. I'm going to have to reload that back into our timeline, just because it's a slightly different clip, and now I want to reveal more detail in this line. I'm going to use the scroll on my mouse to make the clip taller so I can see more detail. And what it's going to do is reveal the opportunity to get some key frames and we've seen this before. Make sure you have the clip selected. Now, I want to work specifically with speed.
So, I want to right click on the FX button, jump down to time remapping, and choose my one option which is speed, and now when I keyframe something down here, it should reflect in my effects control, and vice versa. So how would I do this? Well, I'm going along, I'm watching this at normal speed, and I say oh yeah It'd be really nice as I'm pouring the sauce to get a little more detail there, so I want to slow it down. So I need to place a key frame right here where the playhead is part.
I'm going to simply press the Cmd key or the Ctrl key on Windows and click right on the timeline, and you'll notice that in my timeline, I now have this little yellow icon and I have a similar icon up here in my Effects control panel. They're directly related to each other. It's just two ways of looking at the same clip. If I stay in the Effects control panel, and go a little bit later to when I'm done spreading all the sauce, I could create another keyframe by pressing the diamond, and you see I now have that key frame in my timeline.
So right now, there's no change, and I'm getting ready to do that. At the very beginning, if I play it back, up until that keyframe, it's going to play at normal speed. So I'm talking, and I'm talking, and I think instead of slowing it down, I want to jump ahead to where I'm going to put the toppings on. So I can grab this line right here and just pull it up, and you'll notice what's happening is, the keyframe that follows it, I'm seeing a little square that's going to snap to that, and from point 2 to point 3 it's going to play back at over 200%.
Let me let go of my mouse. There, it snaps into position. What we did in the Effect Control tab is reflected in the sequence, and I can hit play, and watch what happens when we get to that keyframe. It really picks up speed, and we can get through that, and I could go dramatic here. I could simply grab it and bring it way up, there',s they'd be making 500% and that way the viewer won't have to watch all of that sauce pouring.
Now as soon as it slows down, boom. It's dramatic. Well, I want to be a little more creative and that's where Premier really excels. I'm going to zoom in to this area in the timeline. You'll notice that the key frames here actually have a split in the middle, and if I grab it in the middle, I can move the key frame, but if I grab it on just one side and drag, what you'll see is a slanted line, because now instead of it jumping from really fast to really slow it's going to ramp down.
So it's not as abrupt, and I can control this. If I Right Click on this you'll notice I now get a little blue handle, and this allows them to create a curve, or a Bezier curve, as some people would know this, where I have a more gradual transition from one speed to the next. If I zoomed in over here you would see the same effect. I'm just pressing the Plus key, and that's our Bezier, and if I extended it there, we're good to go. Once again the Plus key to zoom in, and I can go ahead and modify this as necessary. I'm going to go ahead, hit the backslash key through a couple more keyframes on the sequence in my timeline and just show you how easy it is to ramp up and ramp down the speed of a clip.
This is now going faster, this is going slower. We have created a nice gradual flow from slower to faster and again, I can get that Bezier. So let's take a quick look at what happens. Very quick with the chicken, and we need to slow down to show them the onions are going on, and parsley is very important, and cheese is very important, and we're good to go. So the best want to get your head wrapped around variable speed change is to play with it.
It's to get a feel of what you want and to move your key frames as well as your transitions and your timing. And don't worry that you're going to mess things up because you can always reset all those keyframes or actually delete them by clicking on the little stopwatch next to the speed control in the Effects control panel.
