Smoke Screen
For this lesson, it is e-learning. We are tasked to choose and complete one of the video tutorial at http://www.videocopilot.net/ and the tutorial I picked is the Smoke Screen tutorial (http://www.videocopilot.net/tutorial/smoke_screen/) .
Smoke element
Tex_21_grayscale
As we weren't give any source files, I googled the images online. The images that we will need for the video, will be the smoke element and the background image (tex_21_grayscale).
First, we import the smoke element image to the video then we add a new solid layer by clicking (Layer->New->Solid) and place it below the smoke element image. Then set the trackmat to "Luma Inverted Matte". To colorise the element, we use the adjustment layer (New->Adjustment Layer) and on the Adjustment Layer click on Effect->Color Correction->Colorama.
As the person in the video had mentioned, I agreed that Colorama effect gives us a lot of control over the output image. At the Input Phase we change the Get Phase Fro to Alpha and at the Output Cycle we change the Use Preset Palett to Ramp Grey and we changed the two color to blue, for the opacity we set it to the lowest. The smoke element will be changed to the above image.
Next, we will add random movement to the smoke element by clicking Effect->Distort->Turbulent Displace. This is added on to the Adjustment layer as well. We change the size to 10 and animate the Evolution by clicking on the the alt key+stopwatch. Type in time*100 at the Expression: Evolution. In this way, it will take the current time and multiple by 100 so when we are at one second we will have a degree of Evolution.
Now, we will create a new composition and put in the smoke element that we created. Then we create a new background (Layer->New->Solid) and put it below the smoke element. We add on rotation for the smoke element, again we alt key+stopwatch and key in value+time*5 at the Expression: Rotation. To make the smoke element 3D, we click on the 3D box to activate it.
Then we create a camera(Layer->New->Camera) and put it the texture image(tex_21_grayscale), also turn on the 3D for it and put it above solid background that we created previously.
We will now duplicate the smoke element and to rotate it, we can key in 'w' and rotate the z. Now, we will just duplicate more of the smoke element and scale, rotate according to form the cloud feel.
To colorise the texture image(tex_21_grayscale), we click on Effect->Channel->Invert and then add another Effect->Color Correction->Curves. At the curves, we change RGB, Red curve down and Blue curve up. Now on texture image will look like the image above.
Now, we going to animate the camera by adding the null object(Layer->New->Null object) and activate the 3D mode. We will parent the camera layer to the null object layer and change the value of the position of the null object and set the position keyframe.
Finally, I add on text to the video to end of this exercise. For this exercise, it requires quite a bit of time to do, even thou it seems to be a simple exercise but I spent around 3 hours to complete it. The main problem I faced while doing this exercise, is the adjustment of the smoke element, at first I found it hard to rotate it, then I watch the video again and I realised that I have to rotate the z-axis.
Overall, this exercise is quite interesting and I have learnt something new!
