No stupid questions.
Time, time, time--who's got time these days?
Well, if you watch television or movies for more than about 5 minutes,
you're going to see some kind of speed ramp, time remapping, time warping.
I want to show you how we can do that in Premiere Pro CS5.5.
It's really easy to do and really powerful.
Not only can we ramp from speed to speed,
but we can ramp the ramp itself.
I'll also how show you how time remapping is compatible
from Premiere Pro right into After Effects,
and then I want to tease you at the very end
with amazing warping of time inside After Effects.
I think it's the best way to do it. Let's go have a look.
I'm in Premier Pro, and I'll just hit play,
and you can see this is my buddy Dennis,
who you know from Adobe beginner classes on Adobe TV.
He let me shoot him walking down the street on his cell phone,
and he is being sped up and slowed down.
Normally, when you have a clip selected and you click on this little triangle,
you'll see things like motion and opacity.
Well, hidden down here is time remapping speed.
When you have that clip selected, up in the top in our effects controls,
you can see not only do we have motion and opacity,
but time remapping is always in this panel.
It's normally not key frame, and it's set to 100 percent,
but I'm actually key-framing this down inside here,
and if I want, I can pop this open and see things inside there.
I'm just going to close that up and just show it to you.
What I want to show you is that if I'm in the middle here,
notice how I've set this to 535 percent at the beginning.
He's 100 percent. At the end he's 100 percent.
Then in this middle section, he goes to 26 percent.
How do we do that?
Well, let's go back to the beginning, click on our key frame, and clear everything out.
It says "Action will delete key frames. Do you want to continue?"
Normally, you don't want to, but I want to show you how to create them,
so I will clear them out.
The first thing you'll notice is that my clip got bigger.
This is just something you're going to have to deal with.
When you're slowing down and speeding up a clip,
it's going to start to move unless it has a clip beside it.
If you're doing this kind of time remapping,
try to do it on a layer above your normal cut.
So if you've got your AB cuts on video layer one,
do the time remapping on layer two.
That will allow you to change the speed and change the length of the clip
without interfering with anything else.
I just really have one clip here, so it's not really a problem.
Buried down inside here is the speed setting for time remapping.
When I click on this I can turn on a key frame inside here,
and if I want to change the full clip, I can just drag this up or down.
When I'm going down to 39 percent, you can see what happens.
It shifted that clip all the way over there.
Now, if I want to add a key frame in here and change it to ramp from one speed to another,
I'm holding down the Ctrl key, or the Cmd key on the Mac.
You see it changes to a plus, and I click inside here.
Notice this very specific style of key frame.
It's actually got a split inside it.
So right now we're at a100 percent on both sides.
I'm going to go back over here where I want him to slow down
and also click and then back at 100 percent click again.
The first one is 100 percent. That one is set.
This one is going to be 536 percent, I think I said.
Notice that when I click and drag, without any keyboard shortcut--
no modifiers--I'm clicking and dragging, making the clip faster. It gets shorter.
That's just the law of physics folks.
So he's going from 100 percent to 532 percent to 25 percent.
If we look inside here--I'm just going to zoom in--
you see a quick change from fast to slow.
But if I click inside here and drag, then I'm now setting this as a ramp,
and if I want, I've got a little Bezier handle in here.
I can really smooth this out so it's going from 536 percent to 25 percent that quickly,
and I can do it to the other ones so it's--
let me just zoom in on that one again--
There we go, and it's going to go slow back to 100 percent. Now let's look at that.
When I hit play, it goes up to 500 percent, then really slow,
and then finally back to 100 percent on the end.
A couple of things that you can do on top of this--
if you hold down the Ctrl key, and we add a key frame and drag it--
whoops, I want to make sure that I'm clicking on the right thing--
you'll notice that it will put these little chevrons in there. That is backwards.
He's going forwards. He's going backwards. He's going all over the place.
If we take this down to 1 percent,
we will actually have him looking like he's on a freeze frame.
Although it's 1 percent, it's not really moving 1 percent.
It's moving very slow and giving you a still frame.
That's all speed ramping is inside here.
We call it time remapping inside Premiere Pro,
and we've actually made this compatible with After Effects.
If I take this clip with these settings
and choose "Copy," and we go over to After Effects,
where I have a comp waiting with the exact same settings,
and I paste, you'll notice there are my key frames right inside here.
It's the exact same setting. I'm just going to hit my zero key and preview this to RAM.
So we can send this back over the After Effects and tweak it inside here
or, if we wanted, to add some more effects on top of this.
There's our new composite with him going slow, super fast, and then very slow.
This is great, but if you're like me, this little stuttering of his arm
when you've got it really down here, 25 percent or less, doesn't look natural.
You want areally smooth interpolation or adding of key frames,
and there's only one way to do that and that's time warp.
Time warp is a specific feature of Adobe After Effects,
so you've got to do it in After Effects if you want this effect.
I'm just rendering this now.
Again you just see simple key frames down there where I'm choosing the different speeds.
It starts out at 100 percent, goes quite fast to quite slow,
and watch his arm right near the end.
This is where you'll see all the interpolation or adding of frames.
There he is as fast and then this is the payoff right there. Wow. That's beautiful.
Super fast and super slow.
When you're doing the fast motion
it doesn't really matter if you're doing this in After Effects or Premiere Pro.
The results are about the same. You can't really tell the frame blending at that point.
But the final result of this arm right here--I mean, look at that. That's incredible.
This is using time warp.
If I go over here to my effects and type in "time warp,"
you'll see it in here in my effects.
When we choose this and look at our effects controls,
we've got enormous control in here for that where you can adjust speed,
and we're using pixel motion.
That's what makes this look the best.
Frame mix and frame blending is what the time remapping has
both in After Effects and Premiere Pro,
but pixel motion is basically using vector information
and building new frames in between those two arms
so they don't just stutter from one to another.
It's building new frames inside,
and you get that gorgeous smooth action feeling inside there.
I guarantee you, there's a bunch of skateboarders out there that want
this super slow motion done and a bunch of music videos.
Whether you're using Premiere Pro time remapping or time warp inside After Effects,
Creative Suite CS5 Production Premium 5.5 is really your tool to save you a lot of time.
