Activity Forums Adobe After Effects another pulldown question

  • another pulldown question

    Posted by Tyler Paul on June 2, 2007 at 12:29 pm

    I learned a lot with that last framerate post at the most opportune time. Got a question though.

    A friend shot in 24p and converted it to 30i on capture. He edited. Then he gave the film to me for the special effects and color correction and over all mastering.

    Is it possible to correctly uninterlace the footage after it’s been edited with the pulldown? I understand it isn’t.

    Second question. When I exported as a 30i DV I swear I saw some bad jitters. Were this jitters in my head or was that from AE reinterlacing already interlaced frames? Should I export as 30p DV to preserve the pulldowned frames?

    your fisrt 24p project sounds a lot like my first 24p project… the photographer suggested 24p, and the producer and editor said, oooh! 24p and handed my their spot for ssome keying and effects… by the end i was, uuugh! 24p.

    you can deinterlace the footage, but you will need to split the footage up at the edits into the original shots to be able to do so. you can then reassemble the footage in a 23.976… just re-edit the whole thing… no big deal (sarcasm here)

    but unless this is a very simple editting job or a very special project, i think i would leave it, you just won’t be able to scale or reposition the footage at all, and some effect that envolve other movement may not look quite right and keying will be dificult, but i think it will be passible.

    and you are correct, you will render as progressive… this is becaase you can’t de-interlace the footage, so if you try to interlace the interlaced footage, you’ll get bad results. so you’ll have some oddities as you render effect that will be rendered progressively on footage that is interlaced.
