Have boys and gurls!!

WEll Im creating some tittles adn writing some text om my last project...
Im working with premiere pro 1.5...

im creating a rolling text...but Im having problems with the speed...dont know how to slow it down,,,its speeding upp all the time....some advices about that, i know that is has to do with the roll-optinons...

What I did so far its to change the speed on the timetable.....and it works ok,,,but then when the text is rolling down...its feels like the words are vibrating insome way,,,like makes difficult to read them dont know if Im clear...


Thanks for yr time!
Have a nice day!

I mean:

hey boys and gurls!!
