Årets første oppgave går ut på at vi skal lage en tutorial som har med post-production å gjøre. Jeg syns effekter og etterarbeid av film etc. er stilig som bare det, så denne oppgaven passet veldig bra for min del.
Jeg valgte å lage en tutorial som bare omhandlet Adobe After Effects, og ikke 3ds max. Den går ut på hvordan man lager en slags tåke-effekt. Den kan f.eks brukes som en intro til en film, der logoen eller teksten til filmen kommer fram fra tåka, for så å forsvinne igjen etter en stund. Tutorialen er på engelsk for å treffe et litt større publikum.

Hvis du vil følge denne, så trenger du Adobe After Effects, helst CS4, men er fullt mulig å få til med andre versjoner også.

La oss begynne:
(PS. You can click on the images to make them bigger)
Step 1
In the project area of AE, right click and create a new composition.
Step 2
You can rename your composition to whatever you like, but use something that’s easy to work with. I renamed mine to “Fog_step_01” and changed the resolution to 1920 by 1080 (Full HD).
Change the frame rate to 25 frames per second.
Also, change the duration to 5 seconds. (You can make it longer if you want to, but you have to change everything else accordingly as we go along).
Step 3
Right click in the timeline-area and create a new Black Solid-layer with the following settings.
Step 4
Now it’s time to animate! At frame 0, click on the stopwatch symbol right next to Offset Turbulence in the fractal noise panel. Now drag the slider in the timeline all the way to the right, to 5 seconds. With the selection tool selected (Shortcut “V”) drag the Offset Turbulence-mark (in the middle of your picture) to where it’s shown below.
If you play back your animation you should see the sky moving from left to right.

Step 5
Go to frame 0 and click the stopwatch next to Evolution. Drag the slider to the last frame and change the degrees from 0 to 270.
Step 6
Under the Sub Settings change the Sub Rotation from 0 to 220.
Step 7
Now close up the Fractal Noise tab and add a CC Vector Blur to the Black Solid-layer. Use the settings as shown below.
Step 8
After we added the Blur you should see some black edges around our animation. To solve this we can just scale up the image a little bit. To do this select the Black Solid-layer, press “S” and the Scale option should pop up. Scale it up to about 105% and the black edges should disappear. After this press the little box-like-button to make it a 3D-layer.
Step 9
Create a camera (the same way you created the Black Solid) and make it 28mm, then press “OK”.
After this, rename the Black Solid to Fog_layer_01 so it’s easier to keep track of.

Step 10
Duplicate the newly renamed layer by selecting it and pressing ctrl+c and ctrl+v. Now you should have a new layer called “Fog_layer_02” with its own Fractal Noise and CC Vector Blur. Under the Fractal Noise-tab change the Rotation to -65 and the Scale to 400.
Change the mode of the two fog-layers from Normal to Screen.
Step 11
Select Fog_layer_02 and press “P”, which brings up the Position parameters.
Adjust the Z-axis (as shown above) so that the image looks something like this:
Scale the layer (as done in step 8) so that It matches the size of Fog_layer_01.

Step 12
Duplicate Fog_layer_02 and use the settings below on Fog_layer_03s Fractal Noise:
Step 13
Now we are going to repeat what we did in step 11, but with Fog_layer_03 selected instead.
The Z-axis above may change from person to person depending on if you followed this tutorials composition settings or if you used your own. As long as you match the picture below it doesn’t matter what your Z-axis-settings are.
Scale up the layer so it matches the two other ones.

Step 14
Repeat steps 12 and 13 with these settings:
Step 15
Go to the project tab and select the Fog_step_01 Composition. Drag it down to the “Create a new Composition”-button, release, and there should now be a new Composition called “Fog_step_02”.
Step 16
With the new composition selected, choose the Rectangle Tool (Shortcut “Q”) and mask out the bottom half of your image.
Step 17
Under the new Mask settings you will find a sub-setting called Mask Feather. Turn off the Constrain Proportions and change the value to the right from 0 to 800.
Step 18
Turn Fog_step_01 into a 3D-layer and scale it up a bit (to about 108%) so you get rid of the black edges around the image.

Now duplicate the layer.

Step 19
Select the new layer and adjust the Z-axis position like shown below:

After this you should have something that looks like this:
Step 20
Create an Adjustment layer and add a Tint-effect to it. This is to change the color of the Fog, so it gets a more vibrant color instead of just black and gray.
I have chosen a red color, but you can choose whatever color you like.

Step 21
Go back to the Project tab and drag “Fog_step_02”-composition down to the “Create a new Composition”-button (like we did in step 15). Now you should have three different compositions like shown below:
Step 22
Double-click on the new composition and duplicate the “Fog_step_02”-layer. Change the mode of the new layer from Normal to Screen.
Here’s an image to give you an idea if you’ve done everything right so far:
Step 23
Double-click on the “Fog_step_01”-composition, and then copy “Fog_layer_01” over to the “Fog_step_03”-composition. The layer should now be called “Black Solid 1”. While selected, press “T” and lower the opacity to 50%.
Go to the layers Fractal Noise-effect and change the values so they match the ones below:
Step 24
Make the Black Solid-layer solo and use the Rectangle Tool to mask the bottom half, like we did in step 16.
Step 25
Change the Mask Feather value like we did in step 17, only now you want to keep the Constrain Proportions ON and change it from 0 to 320.
Just uncheck the solo-button and you’re finished! If you play back your animation you should have a pretty nice fog effect to use in future projects etc.
Here’s how mine turned out:
You can also add some text or maybe a logo to make it a little bit more interesting. After you have added something you can animate the Linear Wipe and Gradient Wipe effects to make it look like the text/ logo comes out from behind the clouds.
Here’s my final result:

Var lett å følge denne tutorialen :)
Good work:)
