Re: [Avid-L2] Is Avid RGB export of DNX-175X media really RGB in video essence level?

 

I'm primarily running 6.5.4.7 so the terminology is still 601/709 and RGB.  With the latest versions "Scale to Legal" would be the same as checking RGB as it is taking Full Swing 0-255 to Studio Swing 13-235.  I'm not in front of a V8 right now to confirm the actual terms but that all sounds correct.  Now on the export side does it say Expand to Graphics level or some such thing because while the traditional nomenclature of RGB makes sense to me in both import side, where I'm telling Avid what the file is, and export, where I'm telling Avid what to export to, now the new terminology is less symmetrical and perhaps a bit more confusing for my old farty brain.

I agree with you as export as same as source but I can't use that in this case because we work with DNX-175X media and I really wouldn't want to downgrade the Alexa footage to DNX-145 for color correction etc... just to accommodate the deficiencies of some truck playback system.  This leaves me with only the custom export to make a DNX-145 export.  Now if I did a same as source export can I still check RGB on the export page.  I'm thinking that stuff is all greyed out when exporting same as source but I'm not in front of my Avid right now.  In that case the levels would be 601/709 because that's what I've been working in in Avid, right?

To repeat part of the question I already asked.  How does one work in an RGB project, which I assume would involve RGB content, and monitor on a scope and see something that looks like a legal level?  With my traditional 601/709 setup with a Tek wfm 7020 and program monitor fed HDSDI the levels are all well below 0mV and up to around 750mV.  I don't recall seeing an RGB mode on the Tek scopes, have I missed that option all these years?  Or do you just set some cursors and pretend like these are the new 0 and 700mV?

AFAIK, if you do Same As Source exports (all other QT custom exports I feel one should always avoid), ticking the "RGB" button (now labeled "scale to legal") is enough. Altough some players may not read and apply the flag this adds to the file.
