    Help Improving CS4 Performance

    brettr2 Level 1

      I'm using Premiere CS4 on a Macbook with OS X 10.6.2.  I have a new project with one video track and one audio track.  The audio plays fine but the video doesn't.  It isn't anywhere near real-time and often only renders a frame every few seconds.  Exporting a six minute video/audio project can take 1.5+ hours.  I'm not sure if it is my project settings or my machine.  I'd like help trying to figure out where the bottle neck is. 


      Here are my Macbook specs:


      2.0 Ghz  Intel Core 2 Duo

      4GB RAM

      5400RPM HD w/ 5GB free space but can vary up to 10GB

      NVIDIA GeForce 9400M w/256MB RAM


      The particular project settings:


      Import from Canon 5D Mark II.  Source is 1920x1080 HD.

      Project sequence settings are:

        Editing Mode: HDV 1080p

        Timebase: 23.976 frames/second (I'd like a 24p film)

        Frame size: 1440x1080 vertical 16:9

        Pixel Aspect Ratio: HD Anamorphic 1080 (1.333)

        Fields: No Fields (Progressive Scan)

        Display Format: 24fps

        Preview File Format: I-Frame Only MPEG


      Export Settings:

        Format: QuickTime

        Preset: Custom

        Export Video/Audio

        720x576, 24 [fps], Lower, Quality 100

        48000 Hz, Stereo

        MPEG-4 Video

        Aspect: D1/DV PAL (1.0940)

        Codec Settings: 24 bit


      I'd like to use the finished product on DVD and Vimeo.  Please let me know if there is anything additional you might need to know.  Thanks.

          Only things that are wrong and cause this slomo behaviour, are the CPU, the disk and the source material. Those three factors combined cause this lousy performance. Several solutions: Use other source material that is easier to edit, like DV, or get a real workstation with several 7200 disks and at least an i7. Probably not what you wanted to hear, but your system is way underpowered.

            Thanks.  I had an idea it was probably more my system resources than anything.


            I'll be getting a Macbook Pro with these specs:


            2.54Ghz Intel Core 2 Duo

            8GB RAM

            Solid State drive

            NVIDIA GeForce 9400M graphics


            Depending what happens Wednesday with Apple's new product launch, those specs might be improved.  This question is more for someone that might already have a similar setup:  Should I see a great improvement with that kind of system?  How much affect does 4GB to 8GB RAM have?

              Realize that every notebook is a factor 8-10 times slower than an equally priced workstation. If you want to go slow, go this route. Apart from the cost, it still is an underpowered system.
