XDCAM export - takes too long?

Hi all.  MacPro 5,1 dual 2.66 6-core, 16 gig RAM, OS 10.6.8.

 

Working doing a weekly half-hour show for a major Chicago media heavyweight.  We shoot in XDCAM EX, edit on an XDCAM HD timeline, and export a final QT movie as our deliverable.  Final finished "master" is 22:10:00...and characteristically this takes around 45 minutes to output, after rendering and mixdown.

 

Is this considered normal?  Acceptable?  I've been doing this for a couple of years now, and it seems to be taking longer and longer...I don't recall our 25th show taking this long to export, but our 75th...sheesh, this is painful.

 

Anyone got any tips on how to speed things up?  And as a corollary question, why when I "Export" do all my previously rendered segments turn red again?

    try changing your render settings to prores in sequence settings:  render control.

     

    And as per your other question, don't have a clue, but somethings wrong.

    try it.  see what happens.  It definitely speeds things up while your working.  Not sure if it makes a difference on export.

    xdcam ex is a long gop format.  All you've got to do is look at it funny and you've got to conform it.  Yeah it looks great and you can work with it in the timeline, but renders always take forever. You could just plain ingest it as prorez and be done with it.  Bigger file sizes though.

    Hi Mike,

                Are you exporting Quick time movie , not quicktime conversion? If you're getting a red render line when you export it sounds like you have a mismatch somewhere and that could be the reason the export is taking so long. Also, do you have plenty of space on your drives?

    Here are a bunch of troubleshooting tips

    Try them all.  In particular, I'd try disconnecting from the network (both airport and ethernet) and creating a new user for the workstation.

     

    Also, have you tried running a speed test on your scratch disk?  Could be a problem there.

    You didn't mention what codec you are exporting as your final product. QT covers a lot of ground.

     

    Your show is re-rendering (the return of the red lines) because your final output is not the same as your timeline.

    If I'm reading it correctly, the OP says the material is rendered before export and then goes unrendered after export.  This is not normal fcp behavior.

    I wouldn't worry about the red lines while you're exporting.  Probably just a function of the xdcam workflow.  If you want, I'll run a test here with some xdcam footage and see if I see the same behavior. 

     

    I suggested in your other thread that you do a diskspeed test on the raid.  If things are getting worse, that's the likeliest culprit.  Also, since you're working in a corporate environment with IT controlling many factors, I'd try disconnecting from the network and creating a new user to see if either impacts this problem.   Is there any antivirus software installed on the system.  That can also cause serious problems.

    did a quick test and don't see the red line appear in the timeline while exporting, but I have a memory of seeing this just can't remember the circumstances.  anyone?
