Change the case of text
You can enter or format text as uppercase characters, either all caps or small caps. When you format text as small caps, After Effects uses the small caps designed as part of the font, if they are available. If the font does not include small caps, After Effects generates faux small caps.
Note: Small Caps formatting
will not change characters that were originally typed in uppercase.
