I am using the credit roll which is the one where names fade in and out, not the one that just scrolls down, and it fades in and out much to fast for me. I would really like to slow the credits down a little bit. Is this possible?
There's a little "duration" data field in the upper middle area of the credit roll window. Type in a new value for about how long you think the credits should run, and this will slow them down to that speed.
Sadly, changing this value does not also extend the event on the timeline, so after you've changed the duration, you'll also have to drag out to event to match.
If you're already close to what you want, you can Ctrl-drag the end to lengthen or shorten it a bit and this will change both the length and the speed together, but you can only do this over a range of 0.25x to 4x. So you may want to use the "duration" method first to get into the ball park, then Ctrl-drag to fine tune it.
