Starstepping while Scaling Graphic
on Dec 21, 2006 at 6:50:03 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.
