  render to mpeg-1 fast then slow then almost stopped

  Posted by Mark Palmos on September 19, 2007 at 2:31 pm

  Very wierd this.
  My project is PAL DV, quite a few motion and titlemotion effects, but then again, I had the same behaviour on a previous project earlier today.

  Renders seem to go along just fine, then slow down, and now im looking at frame 5578 (compressor gives NO indication of how many frames there are in total, or what % is done) and the frames are clicking by at about 26seconds per frame! So I may have to Force Quit Compressor and FCP since last time this happened they would not just cancel the operation.

  Earlier when i had this problem, after Force Quitting FCP and Compressor, I rendered the whole mpeg again really fast, with no changes at all to any of my settings…

  I have been using firefox to browse the cow while rendering, and Entourage to field emails from my client…

  Any suggestions most welcome

  one more thing
  I have just force quit, and FCP shows in red saying “not responding” but Compressor is not in red, and after I killed FCP, I could quit compressor normally.

  any clues?

  Mark,

  One thing was not clear from your posts, are you exporting from your FCP timeline using Compressor or encoding from a separate file via Compressor simultaneously while FCP happens to be open???

  Export Using Compressor will re-render everything according to the render settings in your sequence (high-precision YUV or whatever). This can take some major time when it hits text effects, motion blurs, glows and the like. I’m not sure how to explain the faster render on second attempt. That suggests FCP has cached the render and re-used it on the second attempt. You should get faster results by exporting a QT movie with current settings and then bringing that into Compressor.

  Hey David, and thanks Tom,
  yep, exporting to Compressor from FCP.
  Going fast it renders several frames per second, going slowly, about 26 secs per frame…

  I did try export a MOV file first, and that also seemed like it was taking ages, so thats when I tried mpeg.

  tomorrow i will be doing some more renders, so will check out for any patterns.
