    Video jerks

    Video Junky

      I have just upgraded to CS5 and 64bit Win7.  32MB RAM with 12 cores

      The video footage I have is from a Sony Z1U camera.


      The video bar in the timeline is yellow

      When i play back the footage in the timeline, the video continues to jerk every 10-15 seconds.  I am just wondering what could be causing this?  Surely Premiere is not taxing this system?

          I don't really think you should use 32MB RAM, use at least 2GB RAM.

            It depends on your setup. If you take a look at the results page of the PPBM5 Benchmark you will notice that unbalanced systems perform badly, even with many cores.

              I'm going to guess that "32MB" is a typo. I think my phone has more than that.

                well, now that was silly.  Yes I meant to say 32GB but in reality I have 24GB instead.  It is an I7

                  Hey, don't feel badly, as when I saw the title of the post, I thought that you were talking about my acting debut...


                  Good luck,

                    Yours is the first i7 I have heard of that contains duodeca cores. Maybe Intel would be surprised as well. Even the future releases after Q4 2011 do not go further than deca or octo cores.


                    Jerking is often caused by unbalanced systems, but unless we know the specifics of your system, it is only guessing.

                      My guess it's an i7 with 6 cores with hyperthreading engaged. What might be helpful is how your hard drives are set up.

                        4x 1.5GB SATA 3Gbps NCQ 32MB 7200 3TB Raid-10

                        Matrox MX02-MAX

                        Adobe CS5

                        Timeline is 32 minutes

                        No crazy effects, just straight up disolves

                          Thanks for the details.


                          Is this a Matrox Project?


                          Have you updated CS5?


                          Do you have the latest Matrox drivers?


                          Good luck,

                            Two possible suspects:


                            1. Matrox


                            2. Raid10 on the mobo.


                            Effectively you have two disks, C and the raid10 and the last one is not as fast as a two disk raid0. Two disks is the minimum requirement, so adding one would not be unwise.

                              Are you telling me that a Raid-10 is less performant that a Raid-0?  I thought a Raid-10 was a Raid 1 & 0.  I have 4 drives total.  2 for the Raid-0 and then 2 for the mirrors giving me a total of 3GB with a 3GB mirror.  I thought that was the best you could do.



                              While I have Matrox, this particular project is not using it so no, it is not a Matrox project, however, yes the drivers are up to date.


                              This is a turnkey system I bought so everything came pre-configured.  There are times with it just hums and then there are times when just switching the export options takes up to 1 minute just to bring the dialog up.  It is very frustrating since I paid oodle gobs of money for this thing.



                              I did the benchmark test and submitted my results.  I am not sure what will come of that.

                              My numbers were

                              "523","17","73","94" - Software

                              "523","17","73","10" - Hardware


                              Thank you both for responding.

                              My system has done an awful lot of crashing as well and I am not quite sure what to make of that but I have been working with Adobe on some of it.  I did manage to find a bug   I smile, because I found one, but at the same time I cry :'( because I found a bug and wanted to use the clock transition.  They have not yet given me a date as to when it will be fixed.
