    My pc is constantly reading the disk


      This may be beyond the scope of this forum, but has been building up over time and now it is to the point where I can't do anything.  As Soon as I launch AE my pc starts reading the disk and my progress is slowed to a crawl.

      I am trying to run "Ram Preview".  In the past I had no problem with this, but now my pc is struggling.

      I have a long piece of film strip but I have set in and out point, could the long film strip be contributing to the problem?


      I allotted about 1.5 gig of memory for other apps and I have 4.5 gig for after Effects

      .  Initially I had "Enable Disk Cache" checked but out of frustration I unchecked it to see what it did for performance. Things did not get any better.


      I frequently purge memory and cache and I choose to "Clean Database Cache" frequently.  Does not seem to improve anything.

      Now I am going to try

      1) "Uncheck"  "Render Multiple frames simultaneously"

      2) "Enable Disk Cache" again

      Please let me know if you see anything I have done that may be contributing to this problem

          First thing you should do is turn off MP rendering. RAM allocation should be in multiples of 2  so your 1.5 is not good.  MP rendering is buggy and completely ineffective with many video formats and plug-ins.


          You should read up on optimizing performance by simply typing "optimize performance" in the search help field at the top right corner of AE and read up.

            MP rendering with just 6 GB of RAM? Makes no sense. and the answer to your disk activity is your system's temp folder filling up.

              Mylenium  Rick Gerard I pretty much allowed Adobe to pic the temp folder. I thought the folder would auto expand as needed.  I never knew of a folder having a limited file size.  Let me read up on this.


              I know my  pc is at end of life, but I was waiting for it to get to  the end of its string before making a new purchase.

              Worth noting is, I usually buy my new pc from Best Buy.  I need to see and feel before making a purchase.  But I am thinking I may have to buy my next one that will need to meet Adobe specifications from the Dealer/ manufacturer. Any suggestions??

                A choice of new machine depends not only on AE work, but also the OTHER applications you use currently or will use in the future.  Please fill us in.

                  My primary work is with Photoshop, Premier Pro, After Effects, Audition and Chief Architect.   I have moved my training to After Effects  and Premier Pro because I have found more evidence of financial opportunities in Video and moving making.  My next computer will have to accommodate these applications.  Right now I have a pc with Windows 7 professional on it.  I am guessing my next  purchase will have the latest version of Windows what ever on it..  Let me know if you  need additional information

                    Windows 7 is still acceptable. Perhaps when Windows 10 comes out, I'll consider upgrading.

                    That being said, this page should give some ideas of what to get: FAQ: What computer and components should I buy ?

                    And, yes, the ideal solution would be to purchase a workstation instead of a normal desktop. They don't tend to sell those at Best Buy (nothing against them - I actually like Best Buy - but they probably don't have what you need).

                      Guys I just wanted to get back to you on my original questions about the pc is constantly reading the disk drive.


                      I made a couple of changes,


                      • I went back to Premier Pro and Isolated the pieces of video I wanted to work with in After Effects and cut them into short clips no more than 25 seconds long.  This way After Effects is not rendering a portion of a long clip
                      • Then I made the changes you guys suggested see the screen capture below.  I hope I got this right.  Bottom line is:  everything seems  to be working just fine.  AE still loses it way sometimes and I have to shut it down a restart and it is back to normal.
                      • I also noticed that purging the "Memory and Disk Cache" seems to free up needed resources for AE to use helps a lot.

                      My process for editing is like this

                      • I make a simple edit
                        I create a RAM  preview to decide if I like my edit
                      • I make a new edit
                      • Purge the "Memory and Disk Cache"
                      • May a new RAM preview
                      • Repeat

                      This is a time consuming process, but it the best process I have right now.  Let me know what you think

                        The initial advice still applies: get more RAM.  Ain't no way around that one.

                          Sounds to me like you have a pc problem, not AE problem. Try running Ccleaner (Free version does just fine) to clean up your system cache and registry.

                            Guys I am still considering buying a new computer.  Funds are limited so I need to set priorities.  You guys say I need a work station rather than a lap top which I can not get at Best Buy.  So I probably prefer HP products, I've had great luck with them over the years.  So where do I call to order this work station?
