[Avid-L2] Re: DNxHR and HD

 

So I did some test as knowledge on DNxHR seems rare these days.

If I switch my project to UHD, I can indeed export "Same As Source" in DNxHR - great.

BUT... my sequence is now exported as UHD - i.e. 3840x2160 - where most of my material is HD, and my delivery is HD too.

I tried to make a Custom Size project and make it 1920x1080 but the Avid spotted me trying to trick it and gave me only DNxHD resolutions as a reprisal action...

Back in my HD project, I was able to Ama Link my 4x3 footage (1920x1434) and shift up or down to reframe it within my 16:9 window.

So now I'm back to decision mode and I'm thinking about rendering the archive footage in ProRes HQ (bit overkill, I know) and Transcoding the existing original material from DNxHR to ProRes HQ. That way I'll be able to export ProRes material for the colorist.

Seems a bit complicated, but so far it's the only way I can see.

Happy to hear your experience with DNxHR if you have any!

P.S.:  I am very interested in all your DNxHR questions as I'm about to do the big 4K bend over on a project and am also researching the most efficient workflows to use.  The only thing consistent these days is change in formats and workflows.  Sometimes it's all just to much to swallow.   ;-)

Now the questions are: 

- How do I get the project to a DNxHR environment? Do I have to switch to a UHD project even though I'm delivering HD size, or can I just create a custom size project and make it 1920x1080? Or should I just keep my HD project and transcode the original footage to DNxHD?

- The original footage has a Color Effect added by MediaComposer (based on the camera LUT) but the archive footage is just regular video with no LUT. When I export the film for the colour grader, do I remove the Color Effect to go back to the washed out non-LUT footage? Or should I export two QuickTime files, one for the original material and one for the archive material?

- And most important: what is the air-speed velocity of an unladen swallow? ;-)

Thanks for reading!
