Join Maxim Jago for an in-depth discussion in this video Keyframing made simple, part of Learning Premiere Pro CS5.
Key framing is a core skill for working with effects and sound in any non-linear editing system. And it can seem a little bit overwhelming if you're not familiar with the idea. but it really can be very, very simple indeed. And I'm just going to show you a basic example of working with audio, and a simple example working with video. Once you get this one, you've got for every kind of keyframable effect that any engineer has ever made for software, so pretty useful skill to have. First of all, what have I got here? I've got some audio on the timeline, this is the music for the music video we're working on, and it's at full volume. Now this has come off a CD, which means that it's probobably being fully autenuated to maximize the signal to noise ratio from the CD medium. And what I want is I want the audio to fade up from silence nice and slowly at the beginning.
And to do that all I need to do is add some rubber banding, now on my audio one track here I can see that I've got the somebody loves you .MP3 file that's the original music. And on my keyframe menu I can see that I'm seeing volume and I'm see the level. I can also turn off and on a bypass for any audio effects I've put on here but level works fine for me. In fact I can achieve the same result as I'm going to achieve here by clicking on the keyframes button menu here and choosing, Just Show Me Clip Volume. That leaves me with a yellow line for rubber banding.
But it takes away the menu. It just gives me a slightly cleaner interface. I'll leave that as it was though. Now the adjustment I'm going to make is for the clip segment, not for the track. And you can make separate adjustments to the track. But of course, it won't move when you move the clip. So you need to think about doing that perhaps when you've got picture lock. All I need to do now is go to the pen tool and hold down the Ctrl key or the Cmd key on the Mac and click to Add Key Frame Marks. Now the moment these are just marks that are in time they haven't made any adjustments to my audio level.
If I click on the first one here I can drag this around, and adjust the volume. You can see, as I drag I'm getting a DV rating, I'm getting a position in time. Infact I want this right at the bottom left, I'm going to drag this down to the bottom left corner. Which means that at the very beginning of the clip, it's going to be in silence, and as time passes, we're going to come up to full volume. Now you'll notice that I added two key frames, and then moved them. And I find generally that if you add key frames in time first of all, and then make adjustments to them, it just, it's a little bit easier. Saves you having to adjust things back later on. If I for example drag across a little bit here and click on this flat line, I can adjust the overall level for the audio as well.
And this will adjust the level between keyframes. So if I add another keyframe, I'm holding down the Ctrl key or the Cmd key on a Mac. And now make an adjustment here. You can see I'm just making adjustments between the other keyframes in this track. The net result is I've now created a slow fade out from silence. Actually that really is very slow isn't it. And that is keyframing. What I've just shown you there is pretty much everything you need to know. I can drag these keyframe markers in time.
I can adjust the settings. Now, of course this works fine for audio where I've really just got one control in changing the level for that clip segment. What if I've got multiple controls. But if I move over a little bit here, I've got a clip, I'm going to go back to my Pointer tool to select it. And on this clip I've got the fast color corrector affect, so lets move my timeline over here. Let's say I want this shot to start off looking normal when the guy here is on the street. But as he reaches the greenery I want the whole thing to turn super green, because that's. Just my idea as a, an editor. So I've expanded the fast color corrector, and I'm going to mark a keyframe for the hue wheel here on not the turning which is kind of here when he arrives at the greenery.
And I'm just going to click to turn on these stop watches. And then I'm going to move along a little bit, and by now I want this to be fully green. Now because I've turned on keyframing for these settings, notice I haven't turned it on for other setting on this affect. Because I've turned this on, any changes I make will automatically add a keyframe. And you'll notice that these markers here are keyframe icons. If I now drag this control puck here, over the green, in my hue wheel. What we should see is, if I drag through the clip, now over time, the affect has changed.
This is sometimes called tweening because of in betweening. The system is interpolating the setting between one keyframe, I can go previous keyframe, the next keyframe here. It's been one keyframe setting where I got no color balance adjustment to the next keyframe where I have quite significant color balance adjustments. And notice across this is a realtime effect on my system so I can play. And now over time I don't have to worry about the details premier pro is going to interpret it and apply the effect. For me now you'll notice on the timeline I don't see the effects of this.
I do have a rubber band for my video I've just expanded my video one but right now if I zoom in a bit that is showing me opacity. If I expand my Key Framing menu, I'll see now I've got Fast Color Corrector available and I've got all of the different options available for that effect to rubberband. I have to say though that some effects, and I think this is a prime example. It's not super useful being able to access every single item on this menu. Because you're only ever going to be able to see and adjust one of them at a time with the rubber banding. That's it. That's all you need to know really to work with keyframing. The only other thing to tell you is you can of course turn off keyframing, and Premier Pro will say well, hold on a minute.
If you do that you're going to delete some existing keyframes. That's these items here. Do you want to continue? Yes why not. And those are now gone. You could always adjust settings without keyframing but this just gives you very powerful control over the results of your effects.
