  FCP Crash on H.264 Export

  Posted by Scott Devlin on July 21, 2009 at 2:52 pm

  I am having an issue with FCP crashing in the middle of an H.264 export. For the record, I have recently updated to the new Quicktime and latest FCP. The timeline consists of several clips at 1280X720, 23.98 Square Pixel. There is also a line of audio, and a lower third with an Alpha Channel at the above specs. I am trying to render out a high-res H.264 file, but most of the time FCP completely shuts down part way through the render. Sometimes it renders, but it is jumpy where the alpha channel is used. Can you guys send me in the right direction? Thanks!

  You could have a bad render or media file. First, trash prefs and repair permissions. If that doesn’t help, use the Render Manager to remove the current renders from your project and then re-render. If that doesn’t work, to find bad media, you want to narrow down where the bad media is in the program. First, export the first half of the program to h.264. If that doesn’t work, break that portion in half and export. If it works, the probem’s in the other half. You keep narrowing down until you find the bad media. This is a pain, so hopefully, one of the earlier methods fixes the problem.

  Export your sequence as a Self-contained movie with an uncompress codec (or Prores), then transcode it to H264 with Compressor, QT or MPGStreamclip.
  With H264 it happens the same than with MPEG-2. Everything is rendered again even if the sequence have been fully rendered. Rendering all those effects and compressing t a GOP based format on the fly can be very stressing for FC.
  You also will save time. Multi-pass in H264 means at least three passes.
