    Export times

    Richard M Knight Adobe Community Professional & MVP

      Premiere CS5.5

      2.8 Gig i7

      24 Gb ram

      Windows 7 64

       

      I have just set up the following workflow and I am getting a final export/render speed of about 7 frames/sec is this about right?

       

      2hr 1080 25i timeline with two video tracks with colour correction

      Export via frame server, HQ

      HD to SD script using Avisynth

      convert to Mpeg 2 dvd using two pass 5Mb/sec average, best quality HC encoder.

       

      Total time for both passes is about 12hr.

          How are your export times when using MPEG2-DVD with similar settings instead of using Frameserver and Avisynth?

           

          What color correction was used? MBL or PR? What is your source codec? Length of the timeline? What video card and what disk setup?

            Time line 2 hours Sony EX 1080 25i

            Colour correction Premiere Three-way

            Video card Nvidia GTS 450 with cuda hack

            Black Magic EX sequence

            Source hdd, 2 caviare  black in raid 1- 4Tb

            destination hdd raid 1- 3Tb

            Time using Premiere dvd mpeg2 encoding only about 5 hrs.

              That makes a lot more sense and could possibly be improved upon further without BM. So the long encoding times can be attributed to Frameserver/Avisynth.

                One version of my video included a 4min section where one video stream had 3 soft edge linear wipes. That section rendered at 0.5 fps and the whole film took 17 hours to render. It is often said that you should have a cup of coffee while rendering, I could have gone on holiday!

                 

                While rendering the cpu meter shows 15% usage and the ram 45% are there any ways to use more of my computers power? Do AVIsynth and HC encoder make use of 64 bit computing and multi processors (like the i7)?
