    Black and slow preview on Composition

    HOKORITA

      Hi all, i've an issue on After Effects CC 2017.

      After i close the project for the first time and open it again when i start the preview i see all my composition black, and the rendering previews doesn't work properly anymore.

      Is not a large project, i used 4-5 videos and i used only "timewarp" effect.

      I can't resolve this problem, i need to work with after effects, i can't do it with black preview always...

      i can't see ANYTHING except BLACK, and this happen only when i re-open the project.

       

      This problem was the same on CC 2015

       

      I tried:

      -Disable all effects on videos

      -Magnification zoom fit 100%

      -Change preview quality

      -Update GPU drivers

       

       

      System info:

       

      - Windows 10

      - AMD FX-8350 @ 4.0GHz

      - Sapphire Radeon R9 285 Dual X

      - RAM 8GB x 2 @ 1866MHz

       

      Pls help me, i don't know what to do...

          let's try to isolate this problem. if you open a fresh project with a new composition and create some layers like solid, text and shapes - does it appear black too? how about importing a video file other than the ones you have in this project which .Avi which is an unpopular video that is usually related to a exporting mistake and seem suspiciously related to your problem - where are those files from? give us more information and we might be able to help you. this may be a codec problem.

            When i create new solid layer when i press "ok" my GPU crashes with After effects...

            Never happened!

             

            I tried to reinstall my GPU drivers but same problem, crash when i create solid layer.

             

            No, it works fine.

            I tried to import an mp4 file, i put it on the composition, but when i try to preview won't work and is blocked, but if i drag the time indicator i can see something on preview, only if i drag obviously... if i stop drag it stop.

             

             

             

            where are those files from? give us more information and we might be able to help you. this may be a codec problem.

            The videos come from a game that called AVA (Alliance of valiant arms) and i can record inside the game, when i stop he generate an AVI file that i'm using in my project.

              sounds like a codec problem. I am guessings videos play fine in VLC player... Make sure you have quicktime installed (just the essential components) and try a different video file. Download a youtube video using a free online youtube downloader like keepvid or something. Record you screen using other export settings. You can also convert your videos using VLC player. If you have a codec pack installed then try to remove it.
