This course introduces Adobe Premiere Pro CS6, using a project-based approach that introduces video editors to all the skills necessary to cut their own program. Using a short commercial project as an example, author Abba Shapiro walks viewers through a complete and logical workflow that begins with importing media, creating a basic rough edit, and then refining the cut with music and sound effects, transitions, visual effects, and titles. The course also includes troubleshooting advice, such as reconnecting offline media and using the History panel to undo multiple actions.
A lot of times when creating a program, you may be given graphics and animation. And for the most part, a graphic is just like any other clip unless it has transparency information, and the jargon you will hear is an Alpha Channel. An Alpha Channel is just another way of saying that part of the clip is invisible or transparent. Let's go ahead and we have two clips in our Project Pane. One is a still, and one is a movie. And I am going to go ahead and launch the still into our source monitor, and as you can see, there's black elements right here.
It looks like it's over black. But in reality this is over a transparent channel, and if I open this up in a program such as Photoshop, I would actually see this is clear and not black. Now, if you go to the flyer, to the dropdown menu, you see there is an option that says Alpha, and if I click that, you notice this all goes white. This is actually showing me what the cutout is. Anything that's white is what we're going to see, and anything that's black is going to be transparent. Let's see this in practice. I am going to go ahead and switch to Composite Mode, simply grab this and put this onto the second layer, onto the layer that's directly on top of this really cool Time_lapse footage.
And as you see, when I go ahead and hit Play, I have this great logo in the foreground, and I have my wonderful time-lapse in the background. So this is pretty cool, and this is a clip with an Alpha Channel. Now, only some types of still images can actually contain an Alpha Channel, and a TIFF or a PNG are those types of files. A regular JPEG, you would never see any transparency information. Let's go ahead and delete this and take a look at a moving graphic, or sometimes referred to as an animation with an Alpha Channel.
I am going to select the TIFF in my Timeline and Delete and scroll down, and here we have our kinetECO Alpha movie, and I'll double-click to load that in. And just like before, it looks like it's over black, but when I drag that and drop that onto my Timeline, I can go ahead and scrub through, and you see that it is actually transparent in the background. So as you can see, working with a still image or an animation with an Alpha Channel is just like working with any other type of clip in Adobe Premiere Pro.
The thing to remember is whether you create this animation or this still, or whether you have a graphic artist do it, is that when they save this file, they have to save it in a format that can hold an Alpha Channel, and they have to save it with the Alpha Channel, otherwise your background will be totally black.
