Hi onestop
There are 2 ways to display title cards...
Traditional Option (best for slow computers)
Looking at your image you are using videobox in 'Traditional' mode, where the tiltle card gets the writing from the filename of your track, you can space your filenames so artist & title appear on different lines like so:- "Madonna <---space---> Lucky Star.mp3".
We have a free tool to help you space all your track filenames quickly 'Filename Fixer'.
Modern Option (best for faster computers)
Assuming your tracks are 'tagged' properly, go into your Videobox 'engineer menu--> Title card options' and choose the 'Modern' title card option, this will display artist & title from the track's tags.
