3D Six-Pack's Easy Steps In Premiere

To create a new effect or modify a preset, do the steps below...
(1) Set the transition's progress over time, using the Progress controls. A typical linear transition is 100 to 0 at a layer's head, or 0 to 100 at the tall. To ease-In/out the transition select a handy preset in the Progress menu OR select Via Progress Slider and add the desired keyframes to Progress slider. To hold a transition, set two adjacent keyframes to equal value.
(2) Click Click here to load a preset... to visually choose from hundreds of pre-made transitions (plus saved favorites) in an animated Effects Browser window. Take a look below to see which presets are most appropriate for clip's HEAD, TAIL or for between 2 clips. Click Recent to quickly load a recently used preset. Click Menu to quickly load an effect via a pop-up menu. Or Open for standard Open dialog box.

Important: 3D Six-Pack 3 transitions are available in normal (outgoing clip gradually disappears, revealing the incoming clip) and reversed (incoming clip gradually appears, covering the outgoing clip) direction.
Both directions will look properly only when 3D Six-Pack is applied between two clips.
Use only normal transitions if 3D Six-Pack is applied onto the end of a single clip.
Use only reversed transitions if 3D Six-Pack is applied onto the beginning of a single clip.

3D Six-Pack Presets

In 3D Six-Pack for After Effects there are TWO ways to access presets -- Effects Browser presets, and Premiere Effect Presets.

 

Effects Browser presets

This is the most powerful and visual way to access presets and is where hundreds of transition presets are located. Click the Click here to load a preset... button at the top of 3D Six-Pack to open a large Effects Browser window to visually choose/compare pre-made effects. The Effects Browser is shown below. To explore presets, click a folder in the left pane, then click a thumbnail image to see animated preview. Double-click to apply. To save the selected preset in the Effects Browser click the Save button.

Presets for single-clip transitions:
3D Six-Pack 3 transitions are available in normal (outgoing clip gradually disappears, revealing the incoming clip) and reversed (incoming clip gradually appears, covering the outgoing clip) direction.
Both directions will look properly only when 3D Six-Pack is applied between two clips.
Use only normal transitions if 3D Six-Pack is applied onto the end of a single clip.
Use only reversed transitions if 3D Six-Pack is applied onto the beginning of a single clip.
Shadow/Glow presets are not suitable for use with titles.

Time-saving tips to load presets faster:
The Effects Browser is fast, but sometimes you may already know which preset you want to use, such as when you are applying the same preset repeatedly in a project. In that situation, selecting a preset by one of the following methods can be faster... To see recently chosen Effects Browser presets, click the Recent button. For a drop-down menu of Effects Browser presets, click the Menu button. To use a standard Open file dialog box, click the Open button.

 

Handy tips while working within the Effects Browser:
• To scroll through presets in a folder while keeping your eye on the top preview image for comparison, click a thumbnail in the right pane then use arrow keys.
• To increase/decrease the thumbnail image size, use the Size button at the bottom of the Effects Browser.
• To copy a favorite preset into the My Favorites folder located atop the left column of preset folders, Control-click any preset image and choose Copy to My Favorites. To copy the preset into a subfolder within that folder (such as if you want to organize presets per project or per client), Control-click the preset and choose Copy to My Favorites >> [new subfolder]. You can then name the subfolder as desired. After the subfolder is created, it will also appear in the Control-click menu.
• To rename a preset that is in the My Favorites folder, Control-click the preset there and choose Rename this preset. To remove a My Favorites preset, Control-click and choose Delete this preset.
• To hide any preset, Control-click the preset and choose Hide this preset. To show all hidden presets in a folder, Control-click any preset in that folder and choose Restore all hidden presets from this folder. To temporarily view the folder's hidden presets, which can be handy if you just want to momentarily browse them, choose Temporarily show hidden presets.

Premiere Effect Presets

If you prefer, you can save 3D Six-Pack presets as effect presets in the usual place within Premiere, by selecting 3D Six-Pack, then choosing Save Preset from the Effect Controls panel menu. The saved presets will apear in Premiere's Effects panel, Presets section.
