    Just a minute,


        You say you filmed in XDCAM EX and then edit in an XDCAM HD timeline. Why aren't you using am XDCAM EX timeline? I shoot EX and use an EX timeline, no rendering required because it matches. I just dropped an EX clip into a XDCAM HD timeline and got the red render bar. Is this what you are doing?

    Pretty sure that when you export, the entire timeline has to "render" cause of the mpeg2 long gop structure.

    Well, let's take it easy on the "you"...I'm working with what they've set up at, uh, this major midwest media conglomerate which sometimes used to use the appellation "World's Greatest Newspaper"...


    We shoot in EX as our photogs use Sony EX3s, which only shoot EX; but edit in HD because (A) that's what they use over at the "mothership", where all our systems and tech support/management live; and (B) when feeding the show (playing out from a remote FCP station downstairs into some sort of Kona card and then over a video line to the mothership's facility), the Kona card in question couldn't work with an EX timeline.


    As our local tech here said, "I didn't invent this system, I just work around it."  So rather than expand this discussion to include an entire system-wide analysis, I'm focusing on my machine...specifically, why, within the parameters I'm given and have to use, the machine is getting slower.

    And when I drop EX footage into my HD timeline, I get a green bar...I'm using "safe" RT and dynamic playback settings...don't have to render unless I add an effect.

    I have had the red bar appear across the entire timeline when I have done exports from XDCam/Ex material. I always assumed it was because of the long gop structure, it had to generate the gop cadence fresh from the start to end of the timeline for purposes of a creating the export. The red bar did/does not consistently appear, to the best of my memory.




    1) Your exporting taking twice the real time duration of the timeline does not feel very far off to me, though it has been a while since I did a project that was 100% XDCam. I would start looking at your drive/storage configuration, capacity and how you are connected to the drives and see if you can get some improvement.


    2) Having a green bar on the timeline does not mean "no rendering required to export" it means "no rendering required to display the video pretty close to real time in FCP". If you want the first option, the timeline needs to have the dark blue bar.


    Can you click on a source clip in your browser and type command + 9 to get the clips item properties, and take a screen shot of the properties of the clip and post that here, or report them?

    Then click anywhere on your timeline, and type command + 0 {zero} to see your sequence settings and take a screen shot and post that here, or report the sequence settings here?

    Just an echo: check your sequence settings are identical to the format of the clips you use. If not then a lot of time is wasted converting the final output.

  • Mike Janowski Level 2 Level 2 (285 points)

    ...and another echo:


    "We shoot in XDCAM EX, edit on an XDCAM HD timeline, and export a final QT movie as our deliverable."


    Twas ever thus, twill ever be.  For the explanation why, read up.

    standard clip settings...except for the occasional png or jpg, this is what we use...

    and here's the sequence settings.


    I'm calling this (the time it takes to export a show) a "problem" because it seems much slower than it used to be.  Maybe I'm deluding myself.  And looking at the drive/storage combo is great advice, Meg.  I've told the powers that be from day one that mixing system and media drives is a no-no.  But if someone here could say why this is, in concrete terms, that would give me (a poor day-rate freelancer in a big media conglomeragte world) some ammo to back up that point.  Until then, all I can tell 'em is that this config can cause "anomalies"...of which, I believe, this is one.

  • Mike Janowski Level 2 Level 2 (285 points)

    And an off-topic rant - why can't I give more than one "this helped me" sticker?

  • Michael Grenadier Level 7 Level 7 (20,340 points)

    cause I'm the only one that really deserves it?


    Did you get a chance to check the speed of the raid?  And is there any antivirus software installed?  That can cause all sorts of problems.

  • Meg The Dog Level 6 Level 6 (10,720 points)

    Well, as I kinda thought - you are shooting EX at 1920 x 1080 and editing into a 1440 x 1080 timeline - hence every frame of your timeline will need to be rendered (reconstructed, converted, rebuilt, resized. . . you get the idea) when you export - so your export is really the equivalent of tasking the machine to a show length conversion, in addition to whatever other heavy lifting the computer has to do rendering effects, color corrections, titles and transitions. As I said, given the task at hand, I don't find a 2:1 output time ratio all that surprising.



  • Mike Janowski Level 2 Level 2 (285 points)

    OK, I accept that.  Certainly. 


    Just wish I'd timed the output of show, say, 35, compared with more recent output impression is that it's getting slower...guess it's just a mystery of life (and I hear the conspiracy theorist in my head saying "They build 'em that way...)


    Thanks for your help, all.

  • hyphen Level 6 Level 6 (15,475 points)

    Deleted... Meg covered it! Sorry

  • Mike Janowski Level 2 Level 2 (285 points)

    Thanks...I'll check it out.

    Here's why I don't use a 1920x1080 square pixel sequence:


    1920x1080 SQpix seq.png

    Note the red line.  No matter what the RT setting, I simply would not be able to see any video without rendering.  Now...

    1440x1080 HDpix seq.png the 1440x1080 sequence, I get the green "Preview" line.  Better.  At least I can watch my edits! 

  you might guess, I DO notice an increase in "picture quality" in the properly sized sequence...when viewing the Canvas at 100%, and on the external monitor, the 1920 sequence has a noticeably sharper image.


    And, as you might also have guessed...

    1920x1080 SQpixEX seq.png

    when creating and editing in a 1920x1080 XDCAM EX sequence, I retain the sharpness...AND NO rendering is necessary. 


    just to recap, the reason "the mothership" decided to set things up this  was was because our cameras ONLY shoot EX, but the feed process (we're in a remote location) would ONLY handle an HD master. 


    Thank you all for helping me sort though this.  This calls for a pow-wow with the staff honchos.  When I can demonstrate an improvement in quality AND an improvement in efficiency, I think it's time they informed the mothership that we need to change some things.
