  after effects dealing with quicktime animation or PNG……error!

  Posted by Kazumi Hatori on September 23, 2010 at 9:12 am

  I’m dealing with a project, and trying to precomp few layers(8) and render it first so as to make it works easily and faster.

  So what I did is render those precomp to Quicktime PNG, that I can have alpha channel.
  Oh it works, oops, for a while(that’s why I’m confused),
  works for those rendered files for sometimes and I got a reading frame error from after effects.

  After search the error code database, the error refers to
  “The source clip may be damaged and thus not all frames contained in it may be accessible. If it is a compressed format, not all parts of a given frame may be possible to reconstruct from the compressed info.”

  As I read the stock answer all the time, I am confused why using Quicktime PNG would give me that error.
  I transcoded all the precomps to Quicktime ANIMATION, immediately.

  And it happened again.

  I’m working with a 3K x 1K comp, with 8-10 layers of those precomps.
  Got CS5, with 6GB ram and turned off multi-processing and silly OPENGL.

  I’m still trying to transcode them to still sequences to see what would happen…
  But I think it kills me if I need to render every precomps to still sequences afterward.
  Any idea??

  The error message seems to allude that the clip itself is damaged. Transcoding won’t solve the issue. You’ll want to render a new file.

  Hopefully it isn’t a harddisk issue.

  The clip itself? but it seems no problem when i open it in quicktime and i can use it for quite a while before error comes.

  Now I rendered those quicktime animation to tiff sequences,
  and it works very fine.
  I don’t think the clip is damaged,
  so I am thinking if it is the hardware problem?

  The harddisc not fast enough? to play several 3k quicktime with alpha?
  or not enough ram??

  I got a 7200 system drive and rendered footage at a 5600 footage drive,
  6gb ram.

  I agree with Roland. I was just having the same issue you were just having. Tried all the other mentioned methods I found and noticed that it kept erroring out at the same frame number. So I rendered out that frame new and all is working again.
