To start off you need to select the new still title from the top of adobe premeire this will create a still image which can be made into titles, sub-titles etc, where rolls and crawls are general used for credits.
once you have selected the default still title a dialogue box opens giving you a wide range of options for your text, heres a quick explanation of what all theese things are.
on the right hand side are all the diffrent font options for the titles, size of the font, shape of it, colours, shadows, the useual amount of things you would get within any text editor,
the key part of this box however is the centre screen, it is from here you can see where your title will be placed within the video and adjust it so that it appears where you want it to be placed, of course you can also adjust its posistion later but its common pratice to get the posistion right the first time.
this image shows the title box with the title displaying where it will be located within the video clip.
once you have finished editing the title you can simply close the box and and the title will appear within the video libary ready to be placed within the sequence
