    Clip goes black after 12 minutes

    JStylezzz

      Hi everyone,

       

      I've made a clip for my music podcast, and everything went fine until rendering.

      After approx. 12 minutes of rendering, the preview screen, that screen above the render que goes black, and after everything has rendered, the clip goes black after 12 minutes too.

      The total playing time of the clip is 46 minutes.

       

      I have adobe after effects CS6, I have installed the latest update, my OS is Windows 7 Ultimate x64,

      I tried it on 2 computers:

       

      • I run CS6 11.02 update
      • I did install an update, the 11.02 update
      • My OS is Windows 7 Ultimate x64, on both computers
      • I use only one picture, jpeg format, with 1 effect from Adobe after effects (the audio waveform or spectrum)
      • I'm getting no errors/warnings
      • The problem occured while rendering, the computer was not in use.
      • I never had this problem , but I only use this program for 2 days, and I never rendered until today
      • I'm running no other software
      • I have no third party effects/codecs
      • I have a intel i7 3770K, it has 8 cores, i have 16GB ram installed, and a sapphire VaporX video card, of 3GB.
      • On my other computer I have a AMD Phenom II X4 965 processor of 3.40 GHZ, 8GB Ram installed, and a AMD Radeon HD 6800 of 1 GB
      • I have no third party I/O hardware
      • I am not sure if I use OpenGL stuff, Can I turn it on somewhere?
      • The problem occurs during the RAM preview, normal preview, and during rendering, and also after rendering, when I watch the clip
      • I am not sure if I use Render Multiple Frames Simuktaneously multiprocessing..
      • 1) Import the picture and sound into a new project, add the audio waveform and change it to my needs, then add it to the render que, and render it.

      As I said, I use 2 computers, and on both computers the problem occured.

       

      Any help would be really appreciated, thanks in advance!

          If it occurs consistently at the same time on the same sources, the clips are damaged or you somehow hide/ turn them off from that point on which could be anything from a specific layer switch to some effect. Also using such long audio files could be problematic and the effect run out of memory. AE simply is not the right program for this kind of stuff. As a minor, split up your layer into multiple segments...

            Thanks for the advice, I will try the split up thing.

            You also said that this might not be the right program to do the things I want to, so I wanted to ask if you might know a program that has the ability of making that Audio Waveform / Audio Spectrum, which is made for long clips?

             

            Thanks

              Good question, but I suppose you could find all sorts of visualization plug-ins for Premiere Pro or other video editing tools. In the good old days there were also plug-iuns for audio players like Winamp that could dump the visualizers as video files. If you do a little research, I'm sure you can find enough resources.

                Man, do I feel stupid..

                I re-opened my project, and looked into Mylenium's advice about that I might set it to hide on a specific time, and yes, it's appearance time lasted to a little before 12 minutes.

                I will try to render now, and I guess it should work now.

                 

                Thanks everyone who thought for me!
