    Encoding speed limit in Adobe Media Encoder?

    GFoto

      Dear All,

       

      I experienced a strange (for me) behaviour of AME. I made an encoding test with different coding profiles used the same 1GB big MOV file (from 5D Mark II) on two PC-s, and got a very similar results regarding encoding duration. This is impossible. The difference was only 4-6 secs, see below:

       

      PC-1:

      -          CPU Q9550 (Quad Core 2.8Ghz),

      -          6GB /1333 RAM,

      -          Vista 64Bit,

      -          GT9600TOP,

      -          latest update of Media Encoder.

      -          Encoding Time: 16:40

       

      PC-2:

      -          CPU I7 - 920,

      -          6GB /1600C8 RAM,

      -          Vista 64Bit,

      -          GT9600TOP,

      -          latest update of Media Encoder.

            -          Encoding Time: 16:40

       

       

      The source file was opened directly from AME. Both of them used only 25-35% of CPU. I enclosed two screenshots about it. Any idea? I repeated these tests with DVD and Windows Media 9 profiles, and got similar results.

       

      ps. I have read problems regarding Canon 5DMII videos with PR4. I did not experience any problems expect the preview speed. With I7, it is almost acceptable, but non of slower (tested Q9550, E6400) CPUs gave acceptable playing quality.
