    ripples while panning

    wb7whi

      I am using windows 7 and premiere 7 with a JVC camera.

      Because of the random green pixilation issue with .mod files I first convert to .avi. The avi files look fine in windows media player before importing the files in premiere.

      At some point the quality of the media changes in the editor. As long as the camera is stable the quality is fine but when the camera pans or follows a subject the quality is rippled? Not quite delaminated.

       

      I am using what ever setting premiere defaults to.

          Welcome to the forum.

           

          Unfortunately, "AVI" is but a "wrapper," and almost anything can be inside that wrapper. This ARTICLE will give you more background. What are the specs. of your AVI files? If you have converted to DV-AVI Type II files, you should have an easily editable file. If you have converted to some other form of AVI, then it will depend.

           

          Good luck,

            I dug a bit deeper and came up with the following information

             

            I am using prism video file converter plus

            For the .mod conversion I select output format of .avi

            Below are the options I have for .avi

             

            mpeg4 (native)

            HUFFYUV(NATIVE)

            DV ENCORDER PAL (DIRECT SHOW)

            DV ENCORDER NTSC (DIRECT SHOW)

            MJPEG COMPRESSOR

            CINEPAK CODEC BY RADIUS

            INTEL IYUV CODEC

            MICROSOFT VIDEO 1

             

            I did not change anything initally so the mpeg4 native was selected by default. Wondering if maybe I should select dv encorder ntsc next time?

            Thanks for the help and what is this about a book I have been hearing about? Is it yours?

              I have not used Prism, so I am only guessing a bit here.

               

              The two that I would explore would be:

               

              DV Encoder NTSC

              Microsoft Video 1

               

              I am used to slightly different conversion options, but different programs call the same format/CODEC by different names.

               

              With MPEG material (think that the MOD files are MPEG?), if you use MP4, you will be re-Transcoding to H.264, so will get another compression step.

               

              Good luck,

                The FAQs to the right of this forum list the specs to use to convert various files.
