Opening Text Mask
I achieve the text outline effect via text masking. For each phrase, as the gold text fades out, a text mask fades in and reveals part of the book’s first page. To set up this effect, I:
- Finalized the font setting and screen positions for all four phrases.
- Copied and pasted them, creating a duplicate set of layers.
- Moved the duplicate set into a Pre-Composition (“Init Txt PreC”), and moved this new layer directly under the four “main” text layers. (Note: A “Pre-Composition” acts much the same as a Symbol in Edge Animate or a Group in Photoshop. I think Adobe should decide on one name for this concept and proliferate it across all products!)
- Created a layer for the page image (“1 Nephi 1 TMat”), moved this layer directly under the text Pre-Comp, and assigned its TrkMat to the Alpha Matte for the text Pre-Comp. This automatically turned off the visibility of the text Pre-Comp and turned it into a mask (actually, a collection of four text masks): The page image could now peek through the grouped text elements.
However, just because the Pre-Comp was now being used only as a mask and was no longer “visible,” this did not mean it was dead. Although that layer only showed the page image as seen through its text masks, I could still change how much of that page image showed through by controlling each text mask’s Opacity and effects. Specifically, for each of the four text masks:
- Mask Opacity eases in from 0% to 100% over 1s, starting immediately after its gold “main” counterpart begins to fade away.
- A strong Mask Outer Glow (Spread 5.0%, Size: 120.0) allows the page image surrounding the text mask to show through. I start this glow at 10% Opacity and ease it very slowly to 50% over 5s.
The overall effect is that each gold “main” text element snaps (or fades) in; as it fades out, it subtly trades places with its mask counterpart, which slowly “grows stronger” and reveals more of the page.
By the time all four text masks are up, about half of the page is visible through them. I then fade out the entire masked page image over 2s while a non-mask copy takes its place...
