  Export interlaced footage

  Posted by Marc Thomas on April 22, 2011 at 11:32 pm

  Hi, I’m working on CS3 and CS4 (CS4 is on a friend’s stronger computer for rendering my project).

  I have NTSC footage (lower field, AVI), that I applied Red Giant “Frames” to, to de-interlace, which produced adequate results… but I wanted to make an interlaced version of my movie as well.

  I can’t seem to export my project without getting the “combing” effect.

  Can anyone explain to me, or point me in the right direction for instructions on proper settings to export interlaced footage with the best results?

  Thanks!

  Marc

  Thanks for the response Dave.

  I plan to export as Quicktime Animation to re-import into Premiere Pro to then re-export as mpeg2 for DVD.

  I initially deinterlaced because I was under the impression (which I only recently discovered to be false) that AE deinterlaced by default.

  So I figured I’d go with it, and use “Frames” on my short film to make the deinterlace look better and in the end I’d have something that looked less like video.

  So, now I’d like to export a version that is interlaced like the original footage, which brings me back to my original problem, which is that when I export as interlaced… it looks bad.

  To be clear: if I import my AVI, do absolutely nothing to it, and export as AVI (interlaced, lower field), I get “combing” which wasn’t there in the original video file (which is interlaced, lower field).

  There has to be something I’m missing, as it seems that I should logically be able to export something that at least looks similar to what I’ve imported?

  Thanks,

  Marc

  Thanks again Dave,

  When I said “export”, I meant “render” with Render Queue (sorry for the misunderstanding).

  After many tests… I realized that interpreting the footage as “lower” and then rendering as “field render: lower” Quicktime Animation gave me jagged combing effects , as opposed to interpreting as “lower” and rendering as field render: “off” (which looked amazing and smooth when viewed in Quicktime), which I find confusing.

  Rendering both options (“lower” and “off”) as AVI look almost identical in windows media player. And exporting both options as mpeg2 from Premiere Pro look about the same as well (viewed through WinDVD). Which leaves me still unsure of which to choose?

  Thanks for your help,

  Marc

  Tell me about it!

  It was shot as interlaced.
