    WORKING FOR HOURSSSS - black in comp area and no imported files visible - Please help


      Help please. At a stalemate with months of work.


      I am a creative cloud member.


      Im getting black screen identical to this guy - http://www.youtube.com/watch?v=KFTu3qUUl0w

                    - An odd mix of object's state of existence - the colors are registering, and the images even flash for a split second when i first drag them onto the composition,

      and then its gone. And then when i export the rendering, the reulting file flashes a series of images from in a split second, then black.  Further description below.



      This is first time using After effects since becomming a creative cloud memeber, but I'm pretty fluent with PS and Il, So I'm assuming (hoping) there aren't any "no-brainer" solutions. 



      I have not changed any of the preferences.



      I've looked all over forums which led me to do the following

                     - make sure video card is up to date

                     - uninstalled, reinstalled AE

                                    - version:



      is there a link to an older versions of after affects that i can download which are included in creative cloud memebership






      If you are getting error message(s), what is the full text of the error message(s)?

                - No Error Message

      What were you doing when the problem occurred?

                - Dragging PNGs, JPGs, etc (ALL) onto composition.  I have yet to find an asset that works.

      Has this ever worked before?

           - ?? I've never worked with After Effects before

      What other software are you running?

                - None

      Do you have any third-party effects or codecs installed?

      - K-Lite_Codec_Pack_940_Mega

      Tell us about your computer hardware. Include CPU type and number of processor cores, amount of RAM installed, GPU, number of disk drives, and how any external drives are connected.

                - When in the preferences window>memory and multiprocessing it says “installed CPUs (processor cores): 4”

      Do you have any third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU)?

                - no

      Are you using OpenGL features in After Effects?

                - ?no,

      Does the problem only happen with your final output, RAM preview, or both?

                - VERY STRANGE - I rendered a 30 second avi after importing only one (invisible) graphic.  The exported clip flashes all ten PNG files from which the single one came from.  They all flash up in less than half a second.  Then screen is black for the remaining time.


      Are you using Render Multiple Frames Simultaneously multiprocessing?

                - No


      What is the exact sequence of steps that you are taking?

                - Importing files, any, then dragging onto composition or timeline.  It’s not visible  on composition

          The flaw is here:



          K-Lite is known to cause all sorts of trouble. The bad news is that you will probably have to reinstall your operating system to get truly rid of it, but as a start, uninstall it and reinstall the Adobe apps again. The rest could simply be graphics card issues in combiantion with your not so sexy processor. Install a different version of the ATI driver (12.08, not anything newer) and verify you have all system drivers in your device manager.

            Most of these kinds of problems with both Mac and Windows machines can be traced to flakey 3rd party codec packs. I'd avoid them at all costs.

              What Rick and Mylenium say about K-Lite is true. It is poison to a computer.

                Is there anything written about that? Where?

                I never had issues that could be related to Klite here.

                Moreover, if After Effects properly supported system codecs it could import and export many more formats than it currently do.


                Also consider that the maintainer of K-lite is a developer who works on many high-quality free decoders, encoders and players projects.

                Not to mention that AE and Flash Pro are very known to crash and have graphics glitches on any kind of computer, i.e., Adobe fault.

                  K-Lite makes registry changes that make it take over various video operations. These changes can't be undone by uninstallng the codec pack; they require advanced editing of the registry. Until those changes made by K-Lite are undone, many video programs will not work correctly.


                  We see this problem a lot.


                  It's not just us. See the warning here:

                    Its uninstaller properly undoes all changes that the pack made. I have verified that recently with a Registry snapshot tool. So what you say is untrue. I also suspect your experiences are based on very old versions, or even just pure speculation. The pack and the included codecs have undergone a lot of changes in the past few years. It now uses stuff like LAV Filters, which is truely excellent.


                    In my experience the developers of K-Lite are very helpful and also very quick with fixing any problems that are reported to them. They even help when problems are unrelated to their codecs. I did a search on their forum and did not find any reports of problems related to Adobe products that were in any way caused by their codec pack. If anyone here has any problems that could possibly be related to the codec pack, they should visit their forum for help. If a problem is truely codec related, and not some kind of bug in AE, then they should be able to assist in finding the specific troublesome codec or setting.


                    I assume those Registry changes you are talking about are the ones that deal with preferred splitters. Well, those settings can easily be changed with the included tweaking tool. It is even possible to (temporarily) disable any of the included codecs with that tool.


                    But doesn't AE use its own codecs by default? If third party splitters cause problems, it means that it relies on the standard DirectShow graph builder, which would be a major fail on Adobe's part. Most advanced players use their own custom graph builder, so they can override the codec merits. I would expect no less from a professional product.
