    Same As Source Export Slow

    I have the latest version of avid on an iMac pro. The project I am working on was created about two weeks ago. All of the footage has been transcoded. To make a Vimeo for client review, I usually do an export same as source and then bring it into media encoder. Export QuickTime same as source has always been very fast for me, but now it’s crawling and I have a lot of pressure to get something to the client. Please offer suggestions.  Something is wrong.  Thanks!

    Re: Same As Source Export Slow

    MacOS Mojave

    Version 10.14.2

     

    I am trying some things now.  I really need to fix this.  I didn't want to update to AVid 2018.12.2 for this project, but I did because I was crashing on exiting avid.  I was hoping this version would solve it.  It didn't.  I spent a lot of time working with AJA (I think my io4k is the problem).  They couldn't fix it.

    1.  Reindexing media drive (promise pegasus)

     

    Anything else to try?

    By the way, I did fully mixdown the audio and video before i tried to export same as source quicktime, thinking that had to fix things.  It didn't.

    Re: Same As Source Export Slow

    It seems to be working better after reindexing the media drive.  An unmixed down timeline that is 31 minutes long took 15 minutes to export (quicktime, same as source).  Does that sound reasonable? 

     

    By the way, on a previous try when I mixed down the audio, that took longer than mixing down the video.  That seems odd to me.

    That sounds quite slow to me. Although it also depends on the codec you are using, as a higher data rate will need longer copy times.

    Re: Same As Source Export Slow

    Some thoughts.

    First for a SAS export, the AJA IO plays no part.

    Second the times noted above seem about right to me (maybe a bit slow) if you are going from a sequence with mixed down Video and Audio (let's say ProRes HQ) and everything is occuring on the same drive.  By that I mean all your sources are on drive X and you are writing to drive X.  And that assumes modern high speed drives connected to the iMac with at least USB3.

    But I would NOT be doing a SAS from a sequence that was not mixed down unless I was 200% sure that everything in that sequence was the same codec I was needing for export.  Not doing that can cause issues down the line.

    Third, I agree mixing down audio is generally fast.  But I don't mix in Avid so I can not really say what a heavy, effects laden mix might do.
