    After Effects: Taking 9 hours to render and finalize a 4 minute song with audio spectrum?


      Hello, I am using Adobe After Effects to create some Youtube videos for my music. I have a 4 minute song I've created, and have added 6 layers of audio spectrum, as well as glows, and a few other minor effects. I'm newer to the program, but I still do not understand how the estimated time to render 6,125 frames is 9 HOURS?


      My computer: Dell Optiplex 760

      Intel(R) Core 2 Duo CPU - E7200 @ 2.53GHz

      Ram: 8 GB

      System: 64-bit

      Hard Drive: 250GB


      The Rendering process is set on multi-process rendering. It is using 71% of 8GB ram constantly.

      I am rendering my 4 minute song, along with the 6 layers of audio spectrum, glows, and other effects, along with 2 small text layers.

      This is going into MPEG4 format, with "Best Settings".

      I have tried .FLV, .MPEG4, .H261, and .MOV and they all have the same estimated time for 6,125 frames.


      Could anyone provide me any advice? I need to render and finalize this composition, then upload it to youtube. So it would be great to have decent quality, as well as GOOD sound quality.


      Thank you!

          Don't use compressed audio -- change ac3's, aac's or mp3's to wav or aiff.

          Turn off the multiprocessing--it probably isn't helping one bit, and you may have it set up wrong, too.

          Render to a quicktime movie in Animation, Photo JPEG  or PNG codecs.  Compress later

          Just before bedtime, hit the Render button, have a nice night's sleep, and see how things are doing in the morning.

          Compress to mp4 using Adobe Media Encoder.


          And FYI:  things that you call "minor effects" may in reality be quite processor-intensive, meaning AE has to work harder, meaning it'll take a good deal of rendering time.


          AE isn't a video editor.  It's an effects, motion graphics  and compositing application.  It doesn't work like a video editor.  You can't expect it to react or perform like a video editor.
