    Help optimizing my PC for HD editing


      Recently, I upgraded the cameras & recording system in our city council chambers to HD.  My current PC was

      purchased to edit SD footage (480p), and it excelled at rendering the footage. This same PC struggles to handle HD footage.  Here's some info:


      Council recording system: Data Video HDR-50 (http://www.datavideo.us/products/players-recorders/hd-recorders-players/hdr-50-rackmounted -sd-hd-sdi-hard-drive-video-recorder.html), 1080i recording (don't remember the bitrate off the top of my head, but I think it's around 20)


      PC workstation:


      Manufacturer:        DELL INC.
      Product Make:        XPS 730X
      Windows 7 Professional Edition (64-bit) (Build 7600)
      Memory (RAM):        6135 MB (1066)
      CPU Info:            Intel(R) Core(TM) i7 CPU         940  @ 2.93GHz
      CPU Speed:           2936.6 MHz
      Sound Card:          Speakers (Creative SB X-Fi)
      Display Adapters:    ATI Radeon HD 4800 Series
      Hard Disks:          C:  558.8GB | D:  698.6GB
      Optical:  Blu-Ray burner


      Boot drive: 2 300GB Western Digital 10k in a Raid 0 Array

      Video storage: 750 GB HD storage


      Adobe Production Premium CS5
      C drive is the Raid 0 array: Contains OS & Apps (Premiere)
      D drive is video storage.  All projects & scratch disks are stored on the D drive.


      Our last meeting was 2 1/2 hours long (approx 129 GB), and after some simple editing (cuts & overlays, no color correction), it took approximately 15 hours to convert to 480p 4:3 format for TV (we are still running an SD TV server).  After that finishes, I export using the Vimeo HD setting for the web (H.264), and that took more than 25hrs.


      My questions are:

      1.  I know HD footage is much more hardware intensive than SD, but are my rendering times normal?

      2.  Are there any configurations I can change in Premiere to speed up the rendering time?

         (a) If not, what could be upgraded on this system to improve rendering times? SSD? (this PC is due to be replaced this July, and I'll then use this system as a secondary workstation)


      Thanks for any suggestions!
