The Opacity Trick

Next up, I want to show you what I call the opacity trick. Now, this is a very, very cool trick. Supposing for example, you were fullscreen. So I’ve now made myself fullscreen throughout the entire video. Okay, and supposing UK and you wanted your basic presentation to be like this, then supposing you came to a point where you actually wanted to reveal a bit of a mind map, say at this point here, okay? I mean, you would listen to what you’re saying. Secondly, in filmmaking, this is a local 30 degree. Okay, so it’s all about the 30 degree rule. Supposing I want to reveal whatever’s on this tank below at that point, okay. Well, there’s something called the capacity trick. So I kind of come into the little filmstrip. But this this also works inside Camtasia. And I’m going to add a video action here. And I’m going to tell it take the capacity of me down to zero at this point. So what’s going to happen is that at this point, I’m going to basically fail out of the way, and we’re going to reveal what’s behind. Yeah. And then a little bit further down the line. Let’s just say there. I want to come back to me. So I add another video action in. And I’m going to bring the Opacity up to 100%. Okay. And so what now happens, it will in federal arts, you play it, you watch this. For example, yeah, which is your close up, and which is your wide angle. Secondly, in filmmaking, this is a real cool 30 degree angle of separation. Okay, now, what this means is that if you cut, even if you have two different framings, if you cut from a wide shot to a close up, and it’s more or less the same angle, then it looks very uncomfortable for the person watching the cut. Because if you imagine it, so you see how that worked. And that’s a really useful way to work, okay? Because what it means is that you decide what your master track is, and then whatever your secondary track is your secondary visual track, you can basically effectively cut away to that Then cut back to your master track without doing any finicky editing, without having to do shot by shot editing without having to split stuff up without having to insert clips, none of that all you’re doing is literally vision mixing between one track and another. It’s a very, very elegant way to work. And the same thing, it would work exactly the same way if you were a different size on the screen, because what you’re doing is effective near capacity of that top master track. Okay? I’m just gonna take these two out. Excuse me. This just so they don’t confuse us. And I’m going to basically put myself down. I’m gonna change this back to what it would normally be, which is say down. In fact, 70% is what I decided I wanted to be down Bottom Right, yeah. Well, the same, the same principle can apply if you want to actually for example, make yourself full frame and then bring yourself back down. So in the same way you would add, you listen for the inwards so you’d be listening for where you actually want that effect to happen, right, and then you come back to the other the other place. So supposing I wanted to go full frame at that point, what I would do is, again, add a video actually and and then simply tell it with this video action, make me full size like that, just drag it up, okay? And then a little bit later on, I might say right now bring it back down another video action, and then drag it down to where it was, which is 70%. Okay. Can we get it by drinking? Yes, sorry. That’s why I wanted to go back. So what will now happen is if I just preview that is that what will now happen is that basically I hit this first action, I’m going to become full frame, and then I’ll go back down into the corner. So just have a quick look at this. So you’ve moved around the room a bit, and you’re now looking from a different angle on it right? And then you come back to the other the other place, but the human eye doesn’t go and kind of crash into something in crashes or something. So we try to keep a 30 degree angle of separation. What that means In practice, is that okay, so you see how that worked. And so basically that’s the way you can use video actions to, to change the way things appear. Now the two I suggest you focus on are the Rif, the resizing, okay, and the, and the Opacity trick, that will that will carry the bulk of the editing that you actually need to do visually providing you choose what is your master track and then your subsidiary tracks below it. Because you can always adjust the opacity of the master track or the framing of the master track to allow secondary elements to reveal themselves on the screen at your desire. However you wish.
