    Why_Black space on both R/L side of screen

    nicki_ch

      Hi there,

       

      I was wondering why there is Black Space on both R/L side of screen when I rendering, even when I play the clip in any player such as Media Player Classic.

       

      The original settings of the sequence is:

       

      Sequence: 1440 x 1080 (1,3333)

      25,00 fps


      4800 Hz - Stereo

          That is because Adobe change the PAR.

          If you do not want the black bars you need to crop the top and bottom in the export settings.

            Hi Ann,

             

            Thank you for your prompt reply. I'm brand new to this software could you tell me what PAR stand for, there must be reason that PrPro cs5 automatically keep this black bar?.

             

            From where can I access Crop you mentioned?

             

            Just on the safe side, since I'm going to export them for making DVD in AE and Encore, so I'd like to know if it would cut off the image (in its original proportion) after corping it?

             

            Thanks

              PAR = pixel aspect ratio.   Adobe changed its 16:9 square pixel measurement from 1024 x 576 (in PAL terms)  to 1050 x 576.

               

              But it could also be that you are outputting your HD 1440 x 1080 (1.333) as an SD format such 16:9 (1.458).  Whether it is square pixel or anamorphic, it will

              give you the black tramlines you are experiencing.

               

              To crop (enlarge the clip), select the clip, go into effect control/motion and increase the scale to about 105%.

                There's information here about aspect ratios, including pixel aspect ratio.

                  Hi

                   

                  Just now, I got another problem, I found some "Vignette area Shaking" after using the setting like:

                   

                  Format:H. 264

                   

                  Tv Standard: PAL

                   

                  Field order: none (progressive)

                   

                  Is it because of software / plugins or my computer?

                   

                  But I never met this problem before when I set the Field Order with "Lower" (actully it is automatic, if I choose the preset as PAL Widescreen Hight Quality), but that is just for web uploading. Now I'm going to export it for DVD use, so Mpeg-2 DVD format perhaps is the best choice?

                   

                  I really don't know what for "Lower/Upper/none progressive"?

                   

                  What format should I choose to export for making DVD with AE and Encore?

                   

                  Thinks

                    Cropping in the export settings:

                     

                    For dvd it is best to choose upper as your source is upper.

                      Thanks Ann,

                       

                      This is quite helpful! but if I want to crop more like makig  "a LetterBox", part of the image will be cut off from top / bottom.

                       

                      I followed a tutorial of how to make "LetterBox" without croping image, a kind of film-like by using Motion/Scale, sequence settings like 4:3 standard, it works well in PrPro, but when it display in a player in full screen mode, there is huge black bar on the left and right hand.

                       

                      Could you tell me how to achieve that? I really want to try!

                       

                      Thanks again
