1 hour 16 minutes to export an uncompressed 12 minute timeline

Mar 26, 2013 8:28 AM

Tags: #export #exporting #master #fast #uncompressed

From Final Cut, I could very quickly export a quicktime master file.  For a 10 minute timeline this would take 3-5 minutes.    

 

In PP6,  I am trying to export a uncompressed 'as is' master file and the estimated time is 1 Hour 16 minutes.  Any suggestions on the best export settings ?

 

I would like a highquality master for preview purposes on my TV.   File size is not a concern.

 

There has got to be a faster way.

    It may depend on both the number and complexity

    of the effects you have used in your timeline.

    For example, if every scene is treated with 'Magic Bullet Looks'

    and 'Warp Stabilizer', your export time will be greatly increased.

     

    Also, a bit of system / source media information might offer a clue.

    Don't use QuiRcktime as the codec. Use a different codec. QuiRcktime is 32 bit and using UT/Lagarith or similar you can remain in the 64 bit realm.

    If you want to stay with *.mov, then use the free download Avid dnXhd codec.

    I couldn't find a UT or Lagarith option in the Video Codec drop down.

    You have to download and install:

     

    Lagarith Lossless Video Codec

    Ut Video Codec Suite

    No mention for Mac.

    You hadn't mentioned you are running a mac.

    Avid DNxHD - (quicktime codec)

    http://avid.force.com/pkb/articles/en_US/download/en423319

     

    This is a good quality vs. file size cross-platform QT codec.

    Additionally, if my timeline effects such as Magic Bullet

    are already rendered, why would this slow-down the export ?

    In the export settings depicted in your original post (and #4),

    you do not have the 'Use Previews' box checked.

    Rendered timeline previews should be used for previewing only,

    and are completely ignored during export unless you check that box.

    When you export to your final resolution, all of the effects that you

    have applied to your timeline will be re-rendered.

    Not sure which codec setting to use for Avid ? see attached screen grab.

    The DNxHD setting you use depends on both

    your source material, and the intended delivery.

    Uncheck Maximum Render Quality, and make sure to match your sequence frame rate at 23.976, not 24.

    Thanke Joe.  I checked 'Use Previews'.

    I think you might have misunderstood my post.

    I did not recommend turning on 'Use Previews' for your final export.

    "Rendered timeline previews should be used for previewing only,"

    Please re-read post #12.

    "Max Render" affects the scaling quality, so if for instance the sequence is 1080 and so is the export format, then no scaling, so uncheck and save render time.

     

    You mentioned that file size is not an issue, but it should be. If playing from a laptop, the drive not be fast enough for smooth playback of an uncompressed file. An H.264 file should provide a good quality for what you are doing. Maybe choose an "Apple TV" preset or Vimeo or similar??

     

    Thanks

    (1)   Regardless of wether I check 'use previews' or not,  PP will render the timeline again. Regardless of wether the timeline is already rendered. Correct ?

    Not correct.

    If you check 'Use Previews', your export will 'Use Previews'.

    With this box checked, and if your timeline is preview rendered,

    the export will likely be faster, but will not be the best possible quality.

    (2)  By previewing, do you mean playback of your timeline ? 

    Yes.

    Well...even if the entire timeline has been rendered (green bar), it will still need to be "rendered" or transcoded again to the final export format of choice. The benefit of using rendered previews is that if any of the clips has render-intensive effects that took a long while to render, you will save that extra time. Using previews for final export is ok for making a "preview" to look at. When doing the final export for delivery, best to not use previews to avoid quality loss and recompression.

     

    Here's some info about render bars -

    http://blogs.adobe.com/premierepro/2011/02/red-yellow-and-green-render -bars.html

     

    Not a Mac user, but I think the way Final Cut worked was that pre-renders were in QuickTime, and if exporting to the same QT format, it did not re-render and simply repackaged the QT files together, so it was very quick (or so I read). With Adobe, even if exporting to the exact same format that the clips on timeline are, they will still be transcoded. My exports are nice and quick on Core i7 PC, even for H.264, but laptops (especially a few years old) will take a lot longer unfortunately.

     

    Nice thing with Adobe is that files do not need to be transcoded before you start editing, just edit native files, so maybe the time you save on the front end you make up later.

     

    Thanks

    That was the context of the initial response in post #12.

    Thanks for your extended clarification.

    I don't use MB color effects so can't compare there. From recent threads I saw, MB does take a while to render, so that will definitely increase export times beyond the norm. Also, source format and export format make a difference as well, so we're comparing apples and oranges unless everything is relatively matched up between us.

     

    My source files are usually 1080i HDV, and exporting to MPEG-2 DVD or H.264 for web. DVD is faster than realtime, and H.264 for web can also be, though Blu-ray may take a little longer than realtime. But never anything like you are seeing.Third-party effects are the wild card with rendering times.

    (For a private viewing in our studio)

    Check 'use previews' and un-check 'max render'.   H.264 with a avg data rate of 7 and max of 7. 

     

    (For final delivery to client)

    Un-check 'use previews' and check 'max render' as we often scale the film.

    This sounds like you have a good conceptual handle on the variables,

    and have a solid plan of attack in hand.

    Out of curiosity, how long does your PC take to export  a 10 minute timeline with heavy color grading on it ?   I'm referring to Magic Bullet.

    I can attest to Magic Bullet Looks being big render hog...

    that's why I mentioned it in post #1.

    Will unchecking max render quality reduce image quality ?

     

    With CUDA acceleration on, no.  All it does in increase the render time.
