    Exporting DNxHD 60fps quicktimes

    Hi,

     

    I'm trying to export a quicktime (.mov) of DNxHD 60fps 1080p and am having trouble with the codec settings.

     

    If I export as a quicktime, under resolutions I only get up to 1080i/59.94 220 10-bit. I can set the frame rate to 60 fps but the compressor resolutions don't change. I'm unable to choose the proper data rate.

     

    If I choose DNxHD MXF OP1a format, I see the proper data rate that I'm looking for (1080p/60 DNxHD 290 8-bit). Of course this outputs an MXF file which isn't what I need.


    Thanks in advance for any help.

    What version of MC are you using?

    You might have to take your timeline and drop it into a 1080p/60 project to export what you want.  Not sure what (if any) kind of artificating you might experience when doing so.

    Re: Exporting DNxHD 60fps quicktimes

    I'm using MC 8.4.0

     

    I am currently trying to export from my 1080p/60 project. I've also tried exporting with the DNxHD codec in Adobe Media Encoder as well with the same results.

    If you do a mixdown to ProRes and export as Avid "Same as Source", what happens?

    Re: Exporting DNxHD 60fps quicktimes

    Same thing happens with prores export, but it seems we figured it out.

     

    Under the compressor settings we used 1080p/24 DNxHD 115. Keep the Motion Frame Rate set to current or 60fps and that works on delivering the 290 data rate.

    Thanks for your help!

    Re: Exporting DNxHD 60fps quicktimes

    Did you ever try the "Same as Source" settings?  That should do exactly what you need, and much faster than doing a custom QuickTime Export.  The moment you select "Custom," it invokes the 32-bit QuickTime process.  Same-as-Source bypasses that - and you should get a file that matches your project settings.

    Re: Exporting DNxHD 60fps quicktimes

    I did try "Same as Source". The settings are correct for the most part, but the data rate is less than we we're looking for (290).

     

    We were also looking for a means to convert outside of avid, so the solution we came up with works there too.


    Thanks

    Re: Exporting DNxHD 60fps quicktimes

    Interesting - when you say the data rate is reduced, what do you mean, and where are you checking that?

    Just to fully confirm - you're in a 1080p60 project, you have set your render/mixdown codec to DNxHD 290 in your Media Creation settings, you've selected a Same-as-Source export, making sure that "Custom" is not selected, and then when you open up the resulting file in QuickTime, it's incorrect?  Just want to make sure of the workflow and result - because if that's what's happening, that would seem like a bug.

    Re: Exporting DNxHD 60fps quicktimes

    I see.

     

    In Media Creation I had to press the "apply to all" button under Video Resolution.

     

    It's now exporting with the proper settings. Thanks for your help!

    Nice!  Glad it worked out.  Media Creation settings definitely influence exports.  Get those set properly, and you could save yourself lots of time on export.  I generally avoid "Custom" export at all costs - haven't used anything but Same-as-Source, and QuickTime References, for at least a few years now.
