    50i footage best workflow for progressive output (web/youtube) / deinterlace

    valentindascalita Community Member

      Hello

       

      The reason I have to work with interlaced footage is that the clips are edited for a TV show as well.

      I (usualy) get 1080i @ 50fps clips with fast-paced movement of camera & inside the shot (subject) - car racing.

      Editing in Adobe Premiere Pro 5.5

       

      I am struggling with some stutter & sharpness loss & thin interlaced lines (even after exporting as progressive).

       

      The current workflow is:

                - importing inside an AVCHD - 1920x1080 @ 50i sequence

                - edit

                - export as h264 - 1920x1080 @ 25P /Constrant Bit Rate @ 10MB

      Results not that great : while the smoothness of motion is preserved there is a visible drop in details quality and still visible thin horizontal lines from the interlaced footage.

       

      Also tried:

                - importing inside an AVCHD - 1920x1080 @ 25P sequence

                - edit

                - select 'Always deinterlace' option inside Field Options box (takes extra some time because i have to do this for each individual clip)

                - export as h264 - 1920x1080 @ 25P /Constrant Bit Rate @ 10MB

      Results not that great : stutter motion, more visible drop in details quality and no horizontal lines visible.

       

      My questions are:

           1)What is the best sequence settings for editing 50i settings and exporting for WEB/progressive?

           2)What is the best deinterlace option? ('interpret footage>no field' does not help)

           3)What is the best output/export settings?

       

      Thank you!
