Activity Forums Adobe Premiere Pro Zoom interlaced footage

  • Zoom interlaced footage

    Posted by Marc Nibor on January 2, 2014 at 6:07 pm

    I got some 1080i footage and need to do a slow zoom-in on a few shots (I’m doing the zoom with motion>scale)
    But when rendering I get these ugly scanline artefacts – even if always deinterlace is turned on.

    Now I was thinking to turn on deinterlace on the source clip without making any other changes > export it > and continue working with the new rendered files.
    Since this seems to be quite a bad hack I was wondering if there is a better/more elegant solution?

    Are you judging the render on your comp. screen in Pr?
    This is not accurate.
    Can/are you viewing on external video monitor?

    If the sequence/video you’re editing in is interlaced, I would NOT de-interlace these clips.

    Hi Chris, thanks for you answer
    I watched the rendered result.

    I actually seem to have found a solution that is supposed to work very well. Instead of the built in Adobe deinterlace – Boris BCC Deinterlace should do the trick.

    If your footage is interlaced leave it interlaced.
    What you are seeing is just a preview.
    You can change the playback to suite your needs.
    Zooming in on footage is usually not a good idea. Don’t go beyond 110-115%.
    However you can drop your footage in a sequence with a smaller resolution (1280×720), this will let you zoom it a bit more.
