Join Luisa Winters for an in-depth discussion in this video Adding keyframes, part of Premiere Pro Guru: Mixing Audio Clips and Tracks.
- Changing the levels of our audio whether at the clip or the track level is really important. But so far, we have changed the level of the whole clip or the whole track, and sometimes we need for those levels to go up or down gradually. So when we need for our levels to be louder in some parts than in others, we need to use key frames. Let's go ahead and open sequence 2.3 from the project panel. Go in to sequence, chapter 2, and double click 2.3.
I'm going to go ahead and maximize this panel and expand the tracts. We can see the volume line here on the tracts, and obviously, like we saw before, we can lower it or raise it, and that does the entire clip. If, however, we want to do the clip in increments, in other words, louder in some parts and quieter in others, we add key frames. For that, if you're using the selection tool, press and hold the command or the control key. When you hover on top of the line, your mouse cursor is going to have a little plus sign to the bottom right-hand side of it.
Click on the line at the point in time where you would like to add the key frame, and now you can either change the level of the key frame itself or the line in between the key frames. For example, this one here is going to dip down, remain at a lower level, and then go back up, and that is because I have four key frames. I can do the key framing either here in the timeline or in the effect controls panel.
If I go to the effect controls panel, and I select the clip. I will see right here in the level the key frames that I have added, and I can manipulate them here. I can delete them, add them, change their values all in the effects controls panel. These key frames here correspond directly to these key frames here in the timeline. However, as we saw before, the clip level is not the only level that we have present in here. We also have tract levels.
To see the tract levels click on this key frame icon and then choose tract key frame volume. This is going to now show you the line that represents the volume of the whole tract and not just the clip. We can move it up and down to change the tract level, or we can create key frames. To create the key frames, we do it exactly the same way as we did it before. We can click on the line while pressing and holding the command or control key, and now we can either change the level of the key frame or of the line in between the key frames.
The thing with the tract key frames is this. If I want to delete these key frames, I can do so in the effect controls panel, obviously with a clip selected. And I can choose the individual key frames that I want to delete or modify simply by clicking on it and then pressing the delete key. I will undo that. Or I can click on the name of the property that contains the key frames, in this case the word level, and that selects all of them.
I can then just press the delete key and all of the key frames get deleted. I can also tell the effects control panel that I don't want for changes in time to be possible for the level property. So I can click on this stop watch icon. Premiere is going to give me a warning, and when I click ok, all of the key frames get deleted because changes in time are now not possible. If I want to reset the value, I just click on this icon for resetting.
I will undo a couple of times. If I want to delete the key frames in the timeline, I can do so simply by clicking on it and pressing delete, but if I want to select many more, I can press and hold the shift key as I select and then press the delete key. If I use the pen tool, it's shortcut is the letter P, P for pen. I can add key frames to this line without having to hold the control or command key. I don't need a modifying key to do that.
I can simply just click and drag the key frame up or down. However, if I click on the line to drag it up or down, because it is the pen tool, I'm not really dragging the line up and down. What I am doing is creating a new key frame and then dragging it up and down. With the pen tool, if I want to select all of these key frames, all I have to do is click and drag. All of the selected key frames, like in the previous cases, will turn blue, and then all I have to do is delete.
I will undo that again. If I use the selection tool and I hover on top of an existing key frame, you will see that now the mouse cursor is showing us the diamond-shaped icon on the bottom right-hand side of it. If I press and hold the control or command key, I will get the convert vertex tool, very familiar to those of us who use Illustrator in design or photoshop. And now, I can click and drag on the key frame, and I get handles so that the change in value between the two key frames is no longer linear but Bezier instead.
If I use the audio clip mixer in any of the clips, I can actually use the shortcuts which are the brackets, the square brackets, to bring the levels up and down. Notice that it's doing the levels of the entire clip. If I want for these changes to be more dramatic, in other words, every time I press the square bracket to have more of an impact in the volume, I can always press and hold the shift key as I use that shortcut, and now they go a lot further in their change.
If I apply key frames to a stereo tract, and let's go ahead and do that with the bottom audio, right here, audio 3. I can change the channel volume individually. All I have to do is go to the effect controls panel, and in here, you will see a channel volume property for the left and for the right. So key framing these will be identical to key framing the actual volume. If you want to show it in the audio clip mixer instead, you can always right click and choose show channel volume, and now you can adjust each channel separately from the other in a visual way.
Let's go ahead and delete all of these key frames. For that, I will choose the clip and tell Premiere that changes in time are no longer possible. And I'm going to key frame these levels so they are a little bit more proper. For that, I'm going to do it in a visual way first. I will delete the cross dissolves, and now I will add a key frame at the beginning and a key frame right before the voice starts.
If I lower the volume line, what I get is a diagonal line that goes from the beginning to where the voice starts, which is about this point in time. And what I want to do really is to remain up in level till almost I need to go down, and then lower the volume line. So putting a key frame closer together to the other one will make the interpolation from loud to soft happen quicker.
So for this, we need to listen to the audio obviously, so let's go ahead and play from the beginning. (guitar music) - Seward is a beautiful Alaska coastal - And I can here that the voice could be a little bit louder so I'm going to make it so. - for many cruise ships every year. It offers visitors an up close and personal Alaska adventure - I will lower the music even a little bit more. - Coming to Seward is a visit to Exit Glacier a part of Kenai Fjords National Park.
The Glacier is the only section of the park accessible - And I think I'm pretty happy with that volume so all I need to do is go all the way to the end and add three more key frames. I'll zoom in. And I'm sure that I am in a place where I can see the wave forms, and now I'll add three key frames, two closer and one at the end. I will now increase the volume to about yay. That's zero dB. And now, I want for the volume at the end to just fade out.
So let me just add one more, lower it. And I want for the interpolation to take a little bit longer so I'll do that. So I'll just move it to the left. And let's just listen to that last couple of seconds of the video. - Numerous and diverse come visit Seward and live an Alaska experience. (guitar music) - And I think they interpolation between soft and loud was a little too quick.
So all I have to do is move this particular key frame to the right, and now I'll listen to it again. - live an Alaska experience. (guitar music)
