    DV Encoding Distorts Circle

    Petrula Community Member

      Premiere Pro CC2014 (v8.1)

      Adobe Media Encoder (AME) CC2014

      Windows 7 Pro 64-bit SP1

       

      Problem: DV 720x480 (0.9091 4:3) jpg distorted when encoded to 640x480 (square).

       

      In Photoshop CC2014, I create a

      720x480 (0.9091 4:3) jpg with a circle.

       

      In Premiere CC2014 using "NewSequence From Clip", I create a sequence from a

      DV 720x480 (0.9091 4:3) avi.

      I then add the 720x480 (0.9091) jpg with a circle into the sequence.

       

      With Adobe Media Encoder (AME) CC2014, I create a

      MP4 using 640x480 (square)

      Windows Explorer properties says that the MP4 is 640x480.

       

      In VLC and Windows Media Player (WMP), I play the MP4 on a LED 1920x1080 monitor.

      The circle is a ellipse along the horizontal axis instead of a circle.

       

      I thought AME would scale so the original 720x480 (0.9091 4:3) jpg with a circle would become a 640x480 (square) which would display as a circle.

       

      Why is MP4 elliptical instead of a circle?

       

      My ultimate goal is to display the MP4 on YouTube.

       

      Thanks in advance.
