    Converting PAL to NTSC


      I'm currently working in Belgium, and they have a project they want to sell in United States, but first, we have ton convert every video from PAL to NTSC.
      Now i have a problem with an after effect project. In the project, i have a video (.AVI or .mov), and i can't explain why, when i convert the composition to NTSC format, the video starts shivering, on a vertical way.
      The thing is, i didn't even convert the 24ips to 30ips yet... It's just cause i changed the format, from DV-PAL widescreen, to DV-NTSC widescreen.

      Does anyone have an idea on how i could solve this problem?

      Thanks in advance

          Is the source footage "clean" in terms of being consistently interlaced with the right field dominance? It would only get the shivers/ jaggies if footage interpretation is incorrect or in the source clip upper and lower field sections have been intercut incorrectly.

            Standards conversion isn't as simple as dropping one format into another.

            There's a section in After Effects LiveDocs that explains how to use pulldown to create a clean PAL - NTSC transfer:

              There is one other way - it all depends on what you want to do. Andrew
              Kramer on Creative Cow made a tutorial on how to convert between video
              formats in After Effects. It also included how to make an Animation Preset
              to automate the whole thing:


              Because it converts frame rates it doesn't change timings so the audio is
