    Video's Position Changes after Render

    Level 1
      Product: Premiere Pro CS4
      OS: Vista Ultimate sp1
      RAM: 6 gb installed, but only ~4 gb utilized due to Vista 32-bit restriction

      I took some video footage of a Pendulum concert and now I am trying to edit the clips. They are in .avi format, 1280x720, 29.97 fps, 1.0 pixels. I made a new Premiere Pro CS4 project with the same settings so I could edit the files easily. Everything was going according to plan...

      But after I rendered what I had done so far, I was shocked to see the video smashed up against the bottom and over to the left.

      Why does this happen?

          Best guess is a settings/codec issue.

          First I'd ask if you even got the information right, because it looks like the raw footage is 4:3, where as 1280 x 720 is a 16:9 format. So something here doesn't jive.

          Then I'd ask what camera took the clips? Premiere has a tendency to work best with standard video camera formats, and I'm not aware of any video camera that takes the kind of footage you say you're using.

            For simplicity's sake, I left that info out. But here goes:

            I have a jailbroken iPhone and I used the app "3G iPhone Video Recorder" to get all of the footage. The original encoding was 384x288, 10 fps, 1.0 pixels, .mov file format.

            I tried importing the .mov files into Premiere but they did not render well at all. It was playing at a lot less than 10 fps... More like 2. So I used Canopus Edius 5 to re-encode all of the files to 1280x720 (16:9), 29.97 fps .avi files. I opened the newly created .avi files in Windows Media Player and they did run a lot more smoothly.

            But when I tried importing these files into Premiere and then rendering, I experienced the problem that I explained in my original post.

            So I think we can assume that the original .mov files are the cause of the problem. Maybe they are corrupted, because there is some frame skip. Ah, frustrations.

            Thanks for the help btw.

              Well, that's kind of a given using a cell phone to shoot video.

              What codec was used to create the files out of Edius? (Also, why not just use Edius for the whole task?)

                I hate Edius. I just used it to re-encode the .mov files because they weren't working with Premiere.

                Edius export settings:

                  Eesh. No wonder.

                  For that cell phone original footage, try exporting out of Edius as DV instead.

                    I tried exporting from Edius as DV and I was still running into the same problem while trying to render the video in Premiere.

                    However I tried making a new sequence in Premiere with the preset DV - NTSC 48kHz Standard... And then it worked!

                    Before I had been using this custom preset:

                    General
                    Editing mode: Desktop
                    Timebase: 29.97fps

                    Video Settings
                    Frame size: 1280h 720v (1.0000)
                    Frame rate: 29.97 frames/second
                    Pixel Aspect Ratio: Square Pixels (1.0)
                    Fields: Lower Field First

                    Audio Settings
                    Sample rate: 48000 samples/second

                      ...And I nearly forgot my manners.

                      Thank you very much for the help =D
