  Interlacing on Photoshop graphics

  Posted by Steve Morris on November 16, 2006 at 12:25 am

  I have a slide show which I created in After Effects, and then finished in PP 1.5. Everything looks good with the exception of the Photoshop graphics I added in PP. It is obvious that it is an interlacing problem since the edges appear to be brushed by a comb. The graphics move across the screen in less than 1 second. The “combed” edges do not show when viewed in PP, but appear in the QuickTime file rendered from PP and appear even worse when converted to NTSC DVD and viewed on a TV.

  I have searched the Cow for interlacing and de-interlacing and found a lot, but could not find what I needed.

  Do I de-interlace just the Photoshop object, or the entire 30 min slide show?

  I did a quick test of a short clip of the slide show. De-interlacing in PP improved it alot. I typically do not De-interlace. Is there a downside to doing it?

  Rule of thumb:
  You keep interlace when the display device is interlaced. (TV/video).
  For display on progressive devices (computer, film), one creates without interlace, typically adding motion blur to compensate for fast motion.
