    How to match two different std res widescreen cameras

    jimcarls

      I've got existing wide-screen footage from two different mini-DV cameras that have different approaches to producing widescreen. One is a "true" wide-screen sensor while I believe the other simulates it, although the latter is a slightly better quality camera. When I imported a sample from the first, it created a wide-screen project, but when I imported the second, I get a wide-screen shot with black bars on all sides of the image. I seem to remember that when I edited footage from the same two cameras with Premier Elements 3, I did not have this problem. Oddly enough, if I display the properties of each clip, the resolutions on the two images are identical, altough the pixel aspect ratios are not (see image below). My question is: What is the most efficient way to get a decent matched between these two sources (they represent parallel tracks that will be crosscut). I can crop out the black area and zoom the second camera, but I suspect that I won't like the results when I export test footage. Any suggestions?  Thanks!

          You'll need to enlarge the fake widescreen about 30% to have it fill the screen.

           

          You can do this by changing Scale in the Motion properties. How you do this depends on which version of the program you're using.

           

          In version 11, this property is adjusted in Applied Effects.

            Although, if your fake widescreen seems compressed or squished, you should right-click on these clips on your timeline and change the pixel aspect ratio by selecting Interpret Footage.

              Would they appear squished immediately after capturing, or is there a

              possibility of this happening during export? That clip /does/ appear

              "normal" after capture except for the black frame around it, and the

              image within the "frame" seems proportional to the larger "image space"

              shown by the project. Do you think it's the pixel ratio that is causing

              this? I had a notion that it might be better to try to base the project

              on the smaller image and then interpret the larger wide-screen clips

              down to it — but I suppose the pixel counts of neither are large enough

              to avoid interpolation problems.

                If this was a "real" 16:9 video, I'd say it was the pixel aspect ratio.

                 

                But your post led me to believe that you were using video that was masked/letterboxed so that it would appear to 16:9.

                  video that was masked/letterboxed so that it would appear to 16:9.

                   

                  It wasn't done deliberately after the fact, but your assumption may

                  still be correct. I believe the other camera is a native standard ratio,

                  but has an option to record from just the portion of the sensor that

                  approximates wide-screen. During the capture sequence, Premiere Elements

                  showed an outline in standard proportions with the widescreen image with

                  the usual black bars at the top and bottom. I expected to see this on

                  the actual clip after capturing was complete, but was surprised to see

                  that the wide-screen image was "reduced" within a black frame instead.

                   

                  To complicate any understanding of what was happeing, when I captured

                  the videos (from both the first camera and the letterboxed one), PE

                  displayed a message saying that my camera settings did not match the

                  project settings, but I could not find any setting that could have been

                  changed and the help system was no help. What does that message really

                  mean? Both cameras were DV cameras, not HDV.
