    AME H.264 switches from mp42 to m4v codec at low resolution

      REQUIREMENT: The following format is required to render a 320x240 video to be compatible with a hardware device:

       

      General

      Format: MPEG-4

      Format profile: Base Media / Version 2

      Codec ID: mp42

       

      Video

      ID: 2

      Format: AVC

      Format/Info: Advanced Video Codec

      Format profile: Baseline@L1.3

       

      PROBLEM: Although AME H.264 uses the mp42 codec at higher resolutions, it switches to m4v when exporting 320x240 (as per MediaInfo). A series of encoding tests showed the following for the AME H.264 and MPEG4 export settings:

       

      H.264: m4v codec when exporting Baseline Profile 320x240

      H.264: mp42 codec when exporting Baseline Profile 480x360, 640x480, 1280x720

      MPEG4: mp42 codec when exporting Advanced Simple Profile 320x240

       

      QUESTION: Is there an AME setting that uses the mp42 codec to export a Baseline Profile 320x240 video?
