In the video today, we're gonna learn about all the different ways that you can change
the speed of your clips in Premiere Pro.
How to speed up
Slow Down
maybe even freeze the video,
or if you wanted to, you could reverse all of that
I'm going to show you how to do all of these techniques.
Make them look even smoother with a little thing.
I like to call
Speed Ramping
While I don't have time to showcase to you all the intricacies of how to shoot slowmo
footage properly. I can give you two major rules of thumb to follow that will make it
look better in post. Number one.
Film at a high frame rate or high FPS.
Let's take one second for example, a common frame rate here would be 24 frames per
second. Most camera these days can do 60 frames or 120 frames per second.
So if you were to slow that down by 20 or 40 percent, that means you would get out of
that one second, 2.5 or 5 seconds even.
To put this into practice, let's say my face is the like button and here's you smashing
it. At 120 frames per second, 60 frames per
second.
And 24 frames per second.
The second rule of thumb is to always set your shutter speed to two times the amount of
your frame rate.
So when you're filming at normal speed of 24 frames per second.
The closest that you can get in most cameras in the U.S., at least, is one over 50.
If you were to go above that to say when over 200, then it will look really jittery.
And if you go below one over 50, then it will get a whole bunch of motion blur
and look dreamy almost.
These same things apply to if you don't set the correct shutter speed to
slow motion. So for a frame rate of something like 120 frames per second, the closest
shutter that you can get in most cameras, at least in the U.S., is 1/250.
If you go below that, you're going to get too much motion blur when you slow the footage
down, as you can see right here with the ball on the left as compared to the ball on the
right. That was filmed at the proper shutter speed, double the amount of your shutter to
frame rate. Now that we've covered the basics of wanting to film at a higher frame rate
and the proper shutter speed to match that frame rate.
Let's go ahead and hop into premiere pro.
The easiest way to manipulate the speed of a clip is to highlight it and hit command
R on Mac or Control R on Windows.
Alternatively, you could right click and go to speed duration to also bring up that same
window. But I'm a big fan of using hotkeys to make everything faster, so I'm going to
stick with command R. You can change the clip duration by percentage.
If you want to get faster, you go above on hundred percent.
If you wanna get slower, you can go below one hundred percent.
If you ever want to figure out what the slowest percentage is that you can slow down a
clip too. All you have to do is remember this formula.
Take the frame rate of what your sequence is at and divide that by whatever the clip
frame rate is. And that will give you the percentage or in other words, the frame rate
that you want divided by the frame rate that you have will equal the percentage.
For example, my sequence is at 24 frames per second or 23.976
For those of you really keeping track.
Divide that by my clip's frame rate, which is one hundred and twenty frames per second,
and that will equal a percentage of twenty percent, effectively making twenty
percent the slowest. I can make the clip without any skipped frames or any duplicated
frames. For example, if I changes to 10 percent, you can tell that with my 120
frames per second clip as I stepped through the footage, it duplicates every other
frame. Here are some of the most common slowmo percentages that you'll see.
And if you want to take the time to do the formula yourself, I actually made a slowmo
percentage cheat sheet available for PDF download for free in the description
below. There's also a completely different method to convert your footage to slow motion
called interpreting footage, and I'll cover that later on.
But let's continue looking at the speed and duration window.
If manipulating a clip by percentage isn't your cup of tea.
You could do it by a specific duration.
This stands for hours, minutes, seconds and frames.
This is great for speeding up really long time lapses to a specific duration.
So let's say I wanted to post this time lapse of me setting up for this video shoot on
Instagram, and I wanted it to be exactly a minute long.
So I'm gonna hit zero on my hours, turn my minutes into one seconds
and frames zero. I'm going to hit.
Okay. And it turns my two hour long video clip into a minute long time lapse.
Underneath duration is the checkbox to reverse your clip if you want to.
You can maintain the audio pitch, which I find.
Premiere Pro does a pretty good job within reason.
If you're close enough to the original speed, one quick tip to add onto this
idea of audio pitch. Instead of just thinking about switching the duration or speed of
your visual clips about your sound effects as well. For example, I use this on rushes and
impacts all the time. Here's one drop a comment below
for that example. Every single time a word hit the screen, I use the same exact sound
effect. But what I like to do is actually vary the duration of each time a word
hits the screen. So it sounds a little something like this.
Drop a comment below.
Now, every single time the word hit, I change the speed of the sound effect.
Which one do you think sounds a little bit better?
In my opinion. It's the second one. But could you drop me a comment below.
On which one you thought was better? Ripple edit trailing Clips just means that whatever
you do to the clip that you're working on, if you were to make it longer or shorter, all
of the clips behind it will then move along with that expansion or contraction.
Now if you don't select this and you make the clip longer, all it will do is just make it
long up until the next clip in the edit.
Next in time interpolation, you have the options of frame sampling, frame blending,
and optical flow. Time interpolation is the way that Premiere is going to interpret
the footage. If you were to stretch something out beyond the frames that you have
available, for example, if you wanted to slow something down that was shot at 24 frames
per second. But you wanted to play it back at 50 percent.
What is Premiere Pro going to do with those extra frames in between?
Well, it's either going to use frame sampling, which is just duplicating frames
in between the frames that it does have available with frame blending.
Just imagine Premiere Pro adding Crossfades in between each frame to fill those gaps
and then with optical flow. Premiere Pro is going to artificially create new frames where
they're needed. And it's going to make its best guesses as to what those frames would
look like. Judging by the neighboring frames that it does have available to it, in some
cases, optical flow does an amazing job.
And in other cases, optical flow will look like a computer glitch.
And I should point out that if you plan on using optical flow or frame blending, you're
going to need to render out those clips on the timeline before you see the actual effects
taking place. If you don't do that, it's just gonna look like normal frame sampling
slowmo until you actually export your project.
If you want to do a freeze-frame.
Highlight the clip that you want to work on. Move the play head to wherever you want the
freeze-Frame to start. Right. Click and go to insert frame holds segment.
This will add a freeze frame in between your clip.
The easiest way to make this longer or shorter is to take your cursor and move over to
the side and hold command on Mac or control on Windows to bring up your modified cursor,
which is the ripple edit tool click and drag and this will ripple shift all of the clips
after it forwards or backwards, depending on how you move the cursor.
Now, let's get into finessing a kind of edit like this with speed ramping.
If you wanted to speed ramp something like this shot and premier pro, there's a couple of
ways of doing it. Let's say I wanted to start out at the normal speed.
And right here I could just create a cut, which is add edit in premiere pro bring
up my klip speed duration and maybe I'll go to 20 percent and
then it will abruptly cut from 100 percent, a slow mo 20 percent.
So [SFX] is kind of cool regardless.
And let's say I wanted to go back to one hundred percent yay [SFX]
another the way that you can speed up or slow down.
The clip is the right stretch tool which is found on your toolbar by clicking
and holding where the ripple edit tool is right here and going to the right stretch tool.
This literally just stretches the clip too, however you move it on the timeline.
So right here it's made at 51 percent.
So now this clip is being played back at 51 percent.
If I wanted to go slower, I could stretch it even more.
Twenty nine percent. I find this tool really nice.
If you are trying to hit a specific music edit in between two beats and you just stretch
the clip to wherever you need it to hit. If you have the frames available to you, then
obviously there is the concept of speed ramping,
which is the gradual shift in speed from maybe you 100 percent to
20 percent slowmo or vice versa.
In order to do this in Premiere Pro, you go to the little effects box right here, right.
Click time remapping speed.
And let's say I wanted to slow down right here.
I hold command on Mac or control on Windows.
That creates a little bracket right here.
And I extend those brackets on this side of the bracket.
I'm going to go down to 20 percent for that slowmo.
And now in this in-between spot, it's going to gradually slow down to
20 percent. [SFX] if you want to make it a nonlinear change and make it logarithmic
so it goes like a curve.
You just take those handles and move them like such.
So [SFX] on the back end, I can hit command
again or control on Windows, create another bracketed spot and now
raise it back up to 100 percent.
Use those brackets and adjust a little bit.
So now it looks like this [SFX] speed backup.
And if you remember back earlier in the video, I said I was going to talk about
interpreting footage, which is another way to modify your clips
to automatically convert them to slowmo, which is kind of different than the whole
percentage thing that I was showing you.
So let me showcase that to you right now.
The sequence that I'm working with is 23.976 Per second.
And all of the footage that I want to put into this sequence to convert to slowmo isn't
twenty three point nine seven six. It's at a higher frame rate.
We have 30 frames per second, 60 frames per second, and 120 frames per second.
I mean, give or take some decimal points, but I hope you get the point[SFX].
So in order to interpret this footage to slow motion at 23.976
Frames per second, all we have to do is highlight the clips that we want to convert.
Right. Click, go to modify, interpret footage under interpret footage.
We're going to want to click, assume this frame rate and type in the frame rate
of your sequence. So if you're editing your sequence at 30 frames per second.
Put 30 frames per second here. But I'm editing my sequence at twenty three point nine
seven six. So I'll put in 23.976
For my frame rate hit. OK.
After you've done that, if you notice in the frame rate right here, it's changed it to
23.976. And now all of your clips are seen as slow motion automatically on the timeline.
The only catch here with interpreted footage is that you don't want to go to speed in
duration and then try and slow it down more to like 20 percent.
Like I was doing earlier in the video, because it's going to look like this.
It'll look like super, super slow motion. You're trying to slow down slow motion.
So keep in mind that with interpreted footage, everything's already in slow motion, which
may have you asking the question if you wanted to do something like speed ramping or
maybe play a part of the clip back at normal motion.
What percentage would you need to go back to in order to have it be normal motion?
Well, if you remember that slowmo percentage cheat sheet that I talked about, I actually
cover all of those percentages. So if you wanted to play back something that was at 120
frames per second at normal speed, but it was interpreted, you would have to go up to
five hundred percent.
But again, I cover all of the information in the PDF.
Now that you know to do all those awesome speed ramping techniques inside premiere pro,
you can do something like this.
While I have you here. Did you know that I had my own smooth object animation preset
pack? In fact, I used a lot of those presets in the video that you're watching right now.
If you're interested, it's in the description below.
And if not, hey, I hope you learned something in this video and if you did well.
Share it out with somebody else until next time.
I hope you're out there living a life of abundance.
Bye.
