  Starstepping while Scaling Graphic

  Posted by Dave Martin on December 21, 2006 at 6:50 pm

  Hi Guys

  I have a graphic with alpha channel that I’m scaling from 20 to 60 percent over 3 seconds. The position is also changing slightly (using even numbers). The stairstepping I’m getting is awful. I’ve tried all the deinterlace/flicker filters as well as gaussian blur/broadcast safe etc filters. I’ve tried this in FCP as well as Motion.

  I’m fairly new to FCP but I’m a long time After Effects/Avid/DPS user…Can anyone tell me what I’ve missed?

  I will cross post…Thanks so much!

  Heya,

  Did you try setting the anti-aliasing mode to ‘Best’? You can find it in the second tab of the Project Properties window (Cmd+J).

  Hi Special

  Definitely have that set…thanks for the reply…

  BTW-we have a spirited discussion over on the FCP forum entitled “Re: Stairstepping on Scaled Graphics (Both FCP and Motion)” if you’re interested….

  Thanks for the reply

  Have you tried changing the image size to a smaller one (if you’re only going to 60%)?

  Small-to-large percentages will alias worse than large-to-larger percentages.
