John –

 

In addition to being a very cool QC product, QScan also has some functionality to look at IMF packages and make sure they are correct.  Let me know if you want a demo.

I've been testing making an IMF using the Netflix preset in Resolve 15.  It seems to work but I'm curious about audio tracks being discrete or interleaved if that is the proper term in this context.

 

In my test I took the DPX exported Rec 709 out of Avid and in Resolve told the clip attributes it was video not auto or full so the video levels are fine.  Then I had two multichannel wave files for 5.1 and 2.0.  I think the proper term would poly wav files.  I brought those into Resolve and cut them into the timeline with 5.1 as first track and 2.0 as track two.  The resulting IMF shows 8 channels in the proper order according to the Resolve audio meters.  My question is if the IMF format is like QT .mov files with audio tracks being discrete, individual mono tracks, or interleaved, multichannel tracks?  Does this create problems down the line for servers, encoders, playout devices..  In Avid land with .movs I defaulted to mono tracks for .movs as that worked best for the delivery pipeline.

 

I'm novice in Resolve world so I don't know if Resolve has a function to split poly wavs into discrete tracks like Avid does with converting a stereo audio clip into dual mono.

 

Anybody playing around with IMFs?  I use the term play loosely here.  I just keep telling myself this is just fun fun fun!!!
