  • when AE finishes rendering, video turns black

    Posted by Jakob Schlötter on December 28, 2010 at 6:46 pm

    Hello,

    I have a weird problem with rendering.

    – firstly i rendered the video in h.264.
    – the preview in after effects looked perfectly
    – i stopped rendering, and watched the rendered file in quicktime. looked perfect.
    – i continued rendering until after effects finished rendering.
    – i opened the file with vlc & quicktime. it was completely black, audio worked normaly.
    – here are my settings:

    – then i tried the same with quicktime/jpeg-format, with the equal outcomst:

    here the properties of my used footage (it’s shot with a D90 and directly from camera):

    I reviewed my render-history and i saw that the files were only viewable, when i aborted rendering!!!
    weird!
    I could abort shortly before the movie finishes, but that’s a really stupid solution.

    what is happening here?
    when i searched the forum, i didn’t find a proper solution.

    any ideas?

    greetings,
    jakob

    ps: sorry for the german images, but i think translating is not necessary

    Did you try updating your quicktime version and maybe a nice restart?

    well, i have the newest quicktime version installed (7.6.4) and i restarted several times.

    now i try to render the movie piece for piece uncompressed, and it seems working.
    though it’s not really a nice solution, because i’m running slowly out of discspace 😉

    I read your stock answer already.
    i hoped that i can avoid this.
    also it’s weird, because if i avoid rendering, the file is okay.
    Also, the problem only occurs when i render a composition containing other compositions (I found that out just right now).

    I will try converting the footage, though it doesn’t really make sense to me.
    If it works, I will be confused but happy anyway. Yes, okay, i will try it. Allright.

    Try rendering to qt jpeg or simply to mpeg-2 (which newer versions of Adobe really like, FCP, less so)
