Thanks for the suggestions. I will run a test with the Reduce Interlace  Flicker and  with the 1 pixel Box Blur.

 

I did test runs yesterday in  rescaling the HD - SD in Premier Pro CS6 to compare and AE  had slightly better results with the clips.

You could also try Reduce Interlace Flicker with about a 0.4

Hello all,

 

I remember some discussions of adding a 2 pixel vertical blur to reduce aliasing in SD video. Any recommended choice of blurs? Fast blur, Gaussian any other favorite filters?

I am using AE to scale 1 minute PSA spots from HD (1920x1080i ProRes QT) to letter box  NTSC (720x 486 QT ProRes).

AE CS6 delivers good quality results. There is occasional NTSC aliasing along diagonal lines in the video.  It was suggested to try adding a slight blur to improve the end results.
