RE: [Avid-L2] A little OT, Media Encoder cross-patching surround tracks.

 

Greg –

 

In my work with EditShare, we have been getting a lot of interest in our new QC software, called QScan - https://qscan.editshare.com/.

 

You might give it a try as you get more and more stringent tech specs.

Great info.  So my DNxIO will provide that functionality.  I suppose I could play it in the Black Magic utility which will show up on it's audio meters too.  Not sure if Black Magic Express supports that codec but It's worth a shot.  I would think the black magic express player software would mimic the audio seen by ama linking to the file.  At least that has always been my experience.

 

Running it through QT player would show how the channels get matrixed in it's software.  I wonder if VLC etc... also plays out through the DNxIO.  I haven't tried that.  My overall concern would be if there are certain apps or workflows that would not get things in the correct channel/order.  I guess as always it's good to test a workflow first to make sure all the components will play nicely.

If you have an output device (like a Blackmagic Decklink or some other that can output up to 8 channels of audio), you first go to Audio MIDI Setup and set your audio output device to that I/O, and set it up for 5.1 monitoring (you can test this there as well). Then simply open the file in QuickTime Player and it should play out the channels correctly.

What would be the proper software to check if the file plays the audio out of the correct channels?  For example if I ama link to the file in Avid I assume I would see the tracks in the order Greg mentioned.  What software would this file be likely to be played with that would interpret them correctly and send the tracks to the right speaker?

I've never monitored 5.1 off a computer so I have no experience on that end.

I believe that might be the natural order of surround audio inside an H.264 - I seem to recall that Compressor would make them that way as well. As long as the correct channel audio plays out the correct track, you should be OK. Unless you have some surround H.264 delivery spec I don't know about…

I'm attempting to use AME (adobe media encoder) to transcode ProRes Surround files to H264 surround files. The audio comes out C L R LS RS LFE instead of what AME CLAIMS that it's doing - the more standard L R C LFE LS RS.

Anyone else seen this? I don't see any place I can adjust the patching of tracks yet AME is doing just that.

Several word-smithed googles did not bring any results on this topic.
