[Avid-L2] QT Ref from Avid into Adobe Media Encoder stalls on render start?

 

I've been taking Avid exported QT Ref files into Adobe Media Encoder for years now.  Some of the more complex shows take a bit of time to load in but have worked.  I have primarily been using DNX 175X renders in Avid.  I've also used ProResHQ in my 4K projects.

Today I'm on an HD project using all ProResHQ.  I do my usual upper track safe color and Render everything to ProResHQ.  I was previously rendering upper tracks to ProRes 422 because I was told that was the delivery spec.  Today they said no we need to do XDCam50 with 16 tracks of audio.

I've been doing that type of XDCam 50 422 export on previous series using CC 2014 without issue using QT Ref exports from Avid as the source.  Now I'm on CC 2015 and I've been successfully making H_264 files from QT Ref out of Avid but now today after rerendering to ProResHQ and trying to QT Ref into AME to make an XDCam50 422 AME imports the QT Ref and I can scroll through it when I tape the compression setting and open the settings window.  So AME recognizes the file but when I say encode it just sits there with no sign of life other than the preview window shows the preview screen.  I let it sit for about 15 to 20 minutes but no progress is seen in the preview screen other than the initial appearance of the black window.

If I make shorter QT ref files out of avid like the first minute or so that works and if I take the problematic QT ref and save a self contained version with QT Pro 7 that too works in AME.  I just don't understand why all of a sudden AME is balking or taking a super long time to start encoding.  Very weird behavior.

Anybody else seeing this kind of quirk with AME and QT Ref files.  I had occasions before where it might take 4 to 5 minutes to start encoding after pressing the button but now it just seems to sit there. 

This problem is compounded by the system I'm on is taking for every to boot up after typing in the user password.  I start the computer and get to the log in screen okay but then after entering the password it takes 10 minutes or more to get to the desktop.  This too is new behavior so I'm trying not to restart the computer until I get the current project out tomorrow.  I don't know whether I'm herding cats or dancing on razor blades but I've had better days.

Any suggestions welcome, especially if they involve opening a Bait and Tackle shop and getting out of post.  ;-)
