  Exports Freeze/Jittery

  Posted by Tyler Leisher on July 24, 2008 at 3:27 am

  I recently shot a film in 1440×1080 24p, and it runs great when viewed on my computer but when I run it through after effects or premiere and export it as a .mov it is really jittery/jumpy or it just pauses on a frame, then a few seconds later instantly jumps to another frame and freezes on that.

  if I render it out as a .wmv or anything else it runs fine, it’s just .movs that I have problems with.

  I’ve tried multiple ways of rendering, but my most common one is rendering with photo jpeg (or h264) in best video quality, 1280×720, 24 frames per second and deinterlacing.

  Nothing seems to work.

  Also, whenever I import the clips it imports them at what looks like a 4:3 resolution, when the file says it is a 1440×1080 file. Any ideas why it is doing that?

  h.264 can get jerky. All the data is there, just quicktime player is really badly programmed. If you play it with Nero player, it will play fine.

  Or your file is so huge, it’s possible your hard drive can’t keep up with the data rate transfer.
  Only do this if you don’t need lossless or not need to re-import again to recompress.

  See what your hard drive can take and limit the codec to that speed.
  try jpegmotion 2000 and data rate restrict to kbits/sec:
  read the AE help and search box “interpret” for 4:3 and 16:9 workflow

  what i’m trying to say is that quicktimeplayer doesn’t play as smoothly as nero.
  export a h.264 from quicktime and try playing it back.

  Or……… Instead of a complicated answer that won’t get you anywhere…. Try this. Under the monitor window in AE is a set of small buttons. There is one button with a square and a double ended arrow over it which is called the “Pixel aspect ratio correction button”. Check this to correctly display 1.33, otherwise it just displays at 1:1 which gives the 4:3 screen.

  Cheers
