One word or letter transforms into another by changing shape, font or weight in place rather than swapping.

This is for a motion graphics video. In [scene], turn one word or letter into another with a "Text Morph" (also called text morphing, fluid typography or liquid morphing text): the letterforms reshape in place until they have become the new ones.
Carry every stroke continuously from its old shape to its new one — nothing fades out, cuts or swaps, so the viewer watches one form become the other. Morph letter to letter, shift the weight or font of the same word, or let the shapes melt together and set again like liquid.
Fit the change into [duration], and hold each word long enough to read before and after the morph.

Text sits on a curved path and travels along it, entering, swirling and leaving while following the curve.

This is for a motion graphics video. In [scene], animate a line of "Text on Path" (also called text path animation or text along path): the text sits on a curved path and travels along it, entering, swirling through the bends and leaving.
Keep every letter standing on the curve and turning with it as it goes, so the line of text bends like a ribbon instead of sliding across as a rigid block.
Run the pass over [duration] at an even flow, and keep the path one smooth, sweeping curve so the letters stay readable through the bends.

Paragraphs of text scroll up and tilt back in perspective, shrinking toward a vanishing point; distinct from Credit Roll, which stays flat.

This is for a motion graphics video. Open [scene] with a "Title Crawl" (also called an opening crawl, roll-up or scrolling typography): paragraphs of text scroll up while tilted back in perspective, shrinking toward a vanishing point.
Lay the text on a plane that leans away from the viewer, so lines enter large at the bottom and fade out small in the distance — unlike a credit roll, which stays flat and the same size all the way up.
Run it over [duration] at a steady pace, slow enough that each line can be read before it recedes.
