    Encoding Speed with Media Encoder Issue?

    zorrocbr Community Member

      I have a 5 hour and 36 minute timeline in Premiere Pro CS5 which is composed of mixed assets- some at 29.97, some at 30 FPS, etc.  The timeline is exported to Media Encoder and set for Match Source Attributes Highest Quality  (Quality 5.0, VBR 2 pass, min 3.00, target 6.00, Max 7.00 MBPS).  NTSC 720 X 480 (0.9091), 29.97 FPS, PCM 48hz, 16 BIT stereo.  Format is MPEG2 DVD.

       

      Estimated file size is 18138 MB.  The file takes approximately 36 hours to encode.  Is this normal?

          Probably yes. Aside from the normal conversion with 2 pass VBR, which even under ideal conditions could require up to 3 times the duration of the footage (in your case this makes about 15 hours), you are causing additional operations to conform the frame rates on the Premiere level of things. Also, since this is handled as a Dynamic Link process, you may be a bit short on RAM, which may slow down things further. And then of course the usual with disk speed and file I/O etc.. So it more or less sounds normal, but you should not let the initial rough guesstimates discourage you. Many times these values will get much lower after a while of transcoding when the encoder has a much clearer picture and statistical data about how long it actualyl takes to encode so and so many frames...
