[Avid-L2] Re: Does and Avid or any DPX sequence handle audio?

 

Not sure but they have time code so I thought I better ask.  So the question remains what type of audio delivery is expected with a .dpx file.  From what Rupert told me I really see no reason why the clipster used to make the IMF file couldn't just take a ProResHQ or even better an Avid DNxHRHQX .mov with 8 channels of audio.  Those are smaller and more manageable files.  Given the original source was Panny AVCAVC‑Intra4K 4:2:2 I see no reason to deliver a .dpx sequence other than people don't want to work in any other way than they have before.

In dealing with the QC house that can QC a proresHQ 4K file but refuses to load the Avid LE codecs so QT can play a DNxHRHQX file I am beyond frustrated.  I emailed them and told them I just did this on my earlier startup drive and it took 5 minutes to install the LE codecs. The QC monkey facility responded saying they do 50 hours of QC a week and don't have several hours to reconfigure a bay.  Did they even read what I emailed them?  How does 5 minutes to install a codec package turn into 2 plus hours of reconfiguration?  Oh well QC monkey see, QC monkey no do.  It's all a bunch of doo doo.

Oh wait I forgot my safe place, "Uh, hum,  Every Pixel Counts, Every Pixel Counts, Every Pixel Counts...."  Oh screw it this is just a bunch of crap for the sales department monkeys.

Umm, John... DPX are stills. How exactly would you add audio to a sequence of stills?

As I'm testing the dpx file export on Avid 8.5.2 I'm setting to RGB 10bit keep levels as legal.  Netflix want BT.709 files.  I also checked use selected tracks and I've selected Video and audio 8 channels.  The resulting file when I link ama to the dpx sequence is video only.  I tried a dpx export with only the audio channels selected but I get a prompt that the export format requires video on every frame or some such prompt.  So is dpx an audio less format?  I guess even though Avid has a check box for use marks and one for selected tracks it's probably referring to the video tracks.

What is the standard for including audio for a dpx sequence?
