I just rolled a page of text that was 17 “point” (lines} and it looked just as good as our Chyron or A-72 ever did on an NTSC monitor. I used the motion tab and also the Boris controls with the same results.
Edit a page of text into a sequence exactly 4 seconds long, set Y position key frames at 0 and 4 seconds. At key frame 1 set Y position to 0 and at key frame 2 set Y position to 480 (120×4=480).
