Hi Mark,
Don't think you can do rolling subtitles, using the subtitle facility, but you can using the title room and applying the chosen position, motion etc to the title.

Choose T tab, pick a template, say business001, drag to title track, double click, choose motion tab (snowflake/star), apply begin and end effects, scroll left or whatever..

Use the other tabs for text formatting etc.

Thanks! I was hoping to stream about 10 lines of text across the screen over a couple mins. Does the title method you mentioned allow this, or is it animating a single line of text?

Don't know the limits of a single line of text (it's quite long tho') , trial and error maybe?

Or you could have 10 separate titles each with their own text following one after another adjusted to the main video as required?
