  Rolling Credit issues… How to do it?

  Posted by Mark Weaver on June 1, 2005 at 5:29 am

  Okay,
  So I’ve been trying to get this to work all night and no luck. I’ve been
  reading the “Meyer” book and Adam Wilt’s website about creating rolling
  credits, but they both indicate that ~120 scanlines/second is the minimum
  value for vertical movement in text rolls. However, this is way to fast
  for credits. In fact, I can pop in movie DVDs and the credits don’t
  “appear” to move that fast. This is not to imply anything negative about
  the authors or web page host, but does anyone know how DVD movies have
  nice slow moving credits at the end?

  I’ve tried: 29.97, 59.94, 119.88, and 89.91(just for fun)… I would like
  the speed that I get from 29.97, but as both authors suggest, the text
  doesn’t look good at all.

  Thanks for any help/suggestions… Anything.. 🙂

  Mark

  Well, when film is brought on to DVD, the pull-up works magic. When you scan film it automatically happens that pixels never appear in the same place (thus the same scanline) for various reasons (grain, minor gate variations etc.) and motion looks clearer to the human eye even and especially if it’s slow. You can’t really re-create this effect with the clean anti-alising/ oversampling algorithms in a program, but might consider creating your credits at alrger size and then scale it down. This will in a way introduce some randomness when scaling down (one pixel may appear at one scanline but in the next frame another pixel is used by the interpolation routines). Laong those line all the “bad” tricks like adding noise or blur also work, but may not be what you want since obviously they degrade the image.

  when I do credits and sponsors for a show I work on. I’d put the entire list into Photoshop and then save it as a loooooooooong PSD 640×2250 then I just moved the layer up over the span of a few minutes. Then play around with the duration till I found a timing that suited my needs.

  There’s probably a better/easier way to do it.. but this is what works for me at the moment.

  Jeff,
  Do you see pulsating characters, flickering, or scanline resolution issues? I’ll have to try your idea, but I would have
  thought that a PSD layer of text would look the same as
  a text layer in AE… Guess thats my ignorance. 🙂

  Thanks for the idea.

  Mark
