    kind of artifacts/trails rendering on one PC not the other

    Herwig_L

      Hi!

       

      We have to PCs with After Effects CS5 (different Serial #s) running. One the one there are almost always some problems with a kind of artifacts. The whole project is a mix of In-front-of-the-Camera-Videos of a person and screencasts. In the screencasts there are often trails of the moving mouse. It's not in the footage and when I open the project on the other PC we don't have this problem.

       

      This is the "problem PC":

      Intel Xeon X5550

      24 GB RAM

      Windows 7 64bit Sp1

      NVIDIA Quadro FX 1800

      Quicktime 7.7.2

       

      The working one is:

      Intel Core i7 860

      8 GB RAM

      Windows 7 64bit Sp1

      ATI Radeon HD 4550

      Quicktime 7.7.2

       

      I put a sample of the video here, where you can see what I am trying to explain:

       

      https://dl.dropbox.com/u/78392956/ab_040400_C4.mp4 (rendered on the working PC)

      https://dl.dropbox.com/u/78392956/ab_040400_CK.mp4 (rendered on the problematic PC)

       

      I tried turning on and off OpenGL, multiproceccos and so on and have the latest drivers for the NVIDIA.

       

      Anyone any ideas what's happening? Any help appreciated!

       

      Thanks,

      Herwig

          One is probably set to use OpenGL when rendering. If that's not it, then the color settings don't match on both machines. I'd copy the preferences file from the machine that is working and use that file to replace the preferences file on the one that is.

           

          There's a button on the General Preferences page at the bottom of the panel that will direct you to the file.

           

          Edit: Just read Mylenium's post and he also has a good point. Different versions of a codec can produced wildly different renders in ANY program. Avid, After Effects, Premiere Pro, Vegas.... even Movie Maker or iMovie.

            Actually it probably is. You are very likely having different versions of the relevant Techsmith CoDecs on the systems (if that's what you're using). make sure to install the same versions of Camtasia or whatever on both systems.

              Thanks Mylenium and Rick!

               

              It was the different Camtasia version! I was close to formatting the disc and reinstalling everything... (That would have helped, too, since I would have installed the latest Camtasia then :-)

               

              Thanks a million again!
