  Help!!! My comp has changed tempo – why?

  Posted by Fran Hartnett on March 7, 2007 at 9:07 pm

  Ok, deadline for project is getting way too close, and I open my AE comp,
  which contains audio layers linked to animations and the whole thing seems to be playing at half speed…

  This has never happened to me before, I guess it was a late night last night and I must have changed something somewhere without realising, as I have been working with the audio off.. I just noticed today when previewing with audio that the thing is running slow….

  I’m sure this is something simple, but please enlighten me!

  Thanks in advance, you brilliant people!

  Hi Dave…

  Ok, I tried letting the comp run a few passes, no difference. You see, the audio is not out sync with the visual – in fact, keyframes from the audio tracks are animating the visuals via expressions, so I know the audio is running in sync with the animation.
  The problem is – the whole lot is running slowly – a few wierd things:

  1. the comp settings say the fps is 25, but when the preview is running, the info box says running realtime ram preview, fps 15…. ?

  2. i timed the time it takes for the timeline to play 15 seconds, and it takes 25 seconds for 15 seconds timeline to pass… ??

  3. the audio is actually sloooowed down, but other than that it is playing fine, as i said, its perfectly in sync with the equally slowed down animation….

  something wierd, but i’m sure its something simple i just can’t see….

  Any ideas???

  Hi Dave…

  Still no joy… =(

  I’ve now tried playback at 25% screensize and 1/4 resolution… no difference.
  i really don’t think its the RAM.
  I’m running AE7pro on a 3GHz Dual-Core Pentium with 2Gb RAM…
  should be enough juice for what i’m doing
  with this animation anyway.. it’s not THAT heavy!

  I don’t know..

  Thanks for all your help anyway. Much appreciated.

  God, I really don’t want to build this up from scrach again… theres a good 20hrs work in it!

  Why are you concerned? When you render the file, it will use the correct framerate and timing, so effectively nothing will be screwed. Other than that I can’t think of much. There’s too many potential factors. You may have enabled a layer switch somewhere that you are not aware of or whatever, but like Dave said, you definitely did change something, if only unintentionally.
