    PPro 1.5 media encoder cutting black off edge

    WillProd

      When trying to encode a short vid in PPro 1.5 using the Mpg2 encoder, a good portion of the right side of the video is cut off or clipped or covered over by black.  I don't understand why it is doing this.  When I just render a normal movie with the *.avi raw video there is not black cut off.  Any ideas?  Plus is there a very good article that will help me to understand the complexities of streaming video?

          My first guess on this one is operator error.  You did something wrong.

           

          Without more information, however, that can be only a guess.

            Welcome to the forum.

             

            Now, some questions:

             

            1.) What is your Project Preset?

             

            2.) What is your source footage (full details please)?

             

            3.) What are your full Export settings?

             

            It is most likely that something in those will give the clue as to what is going wrong.

             

            Good luck,

              here are my exact export settings... I've exported video using this settings before and got a video that was perfect.  But maybe i changed something and don't realize it.  i'm using raw footage i shot from an XL2, mostly.  My Project is 30drop frame, interlaced. 720x480 ntsc dv widescreen

                I don't see the Pixel Aspect Ratio listed in your settings.  Make sure that's at 1.0.

                  The pixels need to be square?

                    In this case, yes.

                      not true... i've encoded mpeg2 before.  I was creating demos for the web and my initial one work just fine... this second one isn't turning out and i don't know why.  I've used 16:9 pixel ratio before.

                        not true.

                         

                        True.  Trust me.  Make them square during output at the specified resolution.

                          I did, and what I got was a video very out of shape.  The square pixels made

                          the frame short and  wider... the frame and subjects in the frame looked as

                          if they'd been run over.

                            OK.

                             

                            List your exact media properties, sequence settings, and export settintgs.

                                29.97 fps and some are 23.976fps

                                most are 1.2pixel aspect a few are 0.9

                                 

                                Right away there's part of the problem.  Don't mix and match frame rates and screen sizes.

                                  Well Hot damn, I fixed it!  I initially rendered the sequence as a raw

                                  .avi.  Placed that .avi into a new sequence and then used adobe media

                                  encoder and it works perfectly.  I appreciate the help.  Had no idea mixing

                                  fps and pixel ratio would cause issues.
