Hi all,

I am rendering some HD video files.  Each are about 1 to 2 GB each.  Last night it took this computer almost 9 hours to render just one of these 2 GB files.  Is this normal or do I need to be on the fast track to a genius appointment?

 

regards,

Mike

I am experiencing the same difficulty but my video in also standard definition.  Estimated AVI conversion time is 6 hours for only half (15min) of video.  I suspect that final cut may be set to convert in background or something but I'm not sure.  Hope you find a solution to this problem.

You would be better off exporting a master file to QuickTime with Current Settings & Self Contained.

Then use Compressor to make the AVI files from that.

 

Compressor can be set up to use all the cores of your CPU:

    Thank you for your quick response & valuable recommendations.  Tried exporting to quicktime however & this too was showing at least 3 hours conversion time for 15min of video.  Then I would still have to take it to compressor to convert to AVI which may take another couple of hours.  What is strange is that this in on a new quad core macbook pro running FCP 7.  I previously worked on a dual core macbook pro 2.0Ghz which seems to handle this tasks much faster.

    You don't mention what format "some HD files" are being brought in as...

     

    If you are capturing HDV (for example) your output could be 5-7X that required if you were working with ProRes.

     

    Moral: If the work was faster on a 2.0GHz MacBook, you're on the lower fringe of the minimum processor requirements. Use the tools Apple provides (like ProRes) to maximumize your efficiency, but make a more powerful system a priority if you're going to be doing much of this kind of work.
