    distorted movie file

    robirdman1 Community Member

      PP 5.0: I worked with an AVI file from the Nikon D300s camera. I had read the info on choosing the right parameters and have it as 1280x720.  It appears correct proportionally in the monitor windows.  When I go to export it, I choose Quicktime movie. There are a number of choices such as PAL DV Widescreen, NTSC DV, etc.  It seems not to matter what I choose, visually in the preview..  When viewed in Bridge or played they appear stretched vertically or compressed horizontally. With the NTSC it says that they are now 720x480. How do I get them to appear undistorted?

       

      Also, when I try to browse in Bridge in PP it doesn't come up.  Where is it supposed to be in the file directory to correctly appear?

          What is your intended delivery format.

           

          What is the PAR (Pixel Aspect Ratio) of your footage. 1280 x 720 is usually anamorphic, so will likely have a PAR = 1.3333. If the footage is not Square Pixels, then that could be part of the issue.

           

          With DV NTSC, one has a choice of 0.9, or 1.2 PAR's.

           

          Good luck,

            You have to tell your media player to play it that way.  Most times it doesn't happen automatically.

              Forget about the media player suggestion.

               

              Here is how I do it from any  HD source ( ie. from the edit sequence / timeline).

               

              In AME I immediately go to the output tab after selecting .wmv, QT, flv ..whatever...

               

              I choose a square pixel output. ( Very Important Step - do not choose a PAR apart from square!)

               

              I unlock the proportional setting for the pixel dimesion so that I can vary it...then  trial and error either, the Vertical or horizontal  (depending on the particular output requirement)  so as that I do not have any black bars  on  sides or top/bottoms showing in the "Output Tab"

               

              That exported  file will always play perfectly and correctly in any media player without compression or squeeze. 

               

              Only other step I use in this process  : - Data Rate. (to control file size for various reasons)   

               

              FWIW: I have presets for a variety of  these I regulalrly use ... but all are based on this process.

                1280x720 will always be square pixel never a par of 1.33.

                  Except it won't go onto a DVD, and probably won't be accepted for broadcast.  Square pixels are a valid option for web or computer playback (the preferred option even), but folks should know about the manual unsquishing for media that needs an NTSC or PAL defined ratio.

                    Make sure you update to 5.0.3.

                      Yes but the problem is... the OP is attempting to use a DV Codec (DV)  instead of  something that suits his 16:9 footage (timeline).  I do not believe he is particularly wanting it in a DV (SD) format.

                       

                      Jim : I also dont think the OP was talking about broadcast or DVD in this instance.

                        One could also set the crop proportions in the export settings to 16:9 if its for the web etc.

                        If its broadcast or dvd then export to mpeg2-dvd and not dv avi.

                          Oops - caught me. Should have been HDV Anamorphic 1440, which has a PAR - 1.333 (and not 1280. My bad).

                           

                          Thanks for that correction,

                            I want to put the videos on a DVD that can be played in common usages.  According to the file properties, it says PAR is 1.0.

                              I seem to be missing something.  I have a sequence in the timeline.  I choose FIle> Esport > media > Quicktime. There is an output tab to the right of source tab. I don't see anything about the PAR to choose.

                                Export directly to Encore for a DVD. (Dynamic Link.)
