===== Create a glow effect in ASS subs =====

Add this line to prefix of every subtitles{\fade(200,200)\blur5}

<code>
{\fade(200,200)\blur5}
</code>

----

<code>
{\blur5\3c&HFFC000}
</code>

This way you do not have to change the Style.

----

And via this way you can also let the Outline color transform from one to another:

<code>
{\blur5\3c&HFFC000&\t(\3c&HFF00C5&)}
</code>
