This was asked in a previous thread on V17 that was locked, so here it will be it's own topic.
Has anyone tried DPX 10 bit in vegas, using a high bit project setting and been able to render 10 bit dpx without any level shifts?
As in do nothing to the video, and simply have the output be unity?
From roughly Vegas 13 forward, this has been an issue and am hoping with all of the changes done to V17 that this was also addressed.
@Greg-Kintz
Did you try setting your project to 32 Floating Point Video Levels and check the rendered DPX file within same Vegas project (and same project settings)?

Rendered to DPX
Hi Marco,
I have tried both modes. And if I'm following you correctly took a DPX sequencce, did nothing to it, rendered it out, and then put it back into the same project.
Here's a very short 10 bit DPX test pattern, with two different pattern types:

When I load this into Vegas (in this case 32bit floating point) the clip looks fine.
But If I render it out as DPX, this is the level shift I see when loaded back into the same project.
With your sample sequence my result is same as in my test before. There is no level shift (project properties set to Floating Point Video Levels).
Did you try disabling GPU accelaration?
I just disabled GPU acceleration, restarted and re-rendered with the same result. Good suggestion though.
The fact that you took this into Vegas 16 and was able to output 10 bit DPX from a 32 bit project as unity is VERY encouraging. I have two workstations with different versions of Vegas installed, and both seem to have this issue. I do have older versions of Vegas installed on both, to be able to retain the Dolby AC3 pro encoder. Could these older versions be causing a common glitch? I am try to find a commonality on why both workstations would behave this way.
Of interest and if it helps, while DPX has the level shift in 32 bit render outs, the Vegas intermediate (fo-prores) codec does not.
"The fact that you took this into Vegas 16 … "
I didn't. I use Vegas Pro 17 (see my screenshots above).
That is encouraging! And now for me is worth a trial install. Thank you for your help Marco!
Well.. after fighting with the documented Boris plugin bug, I was finally able to get the trial of Vegas 17 running.
Unfortunately the same problem persists for me with Vegas 17 as it was with previous versions. DPX in either 32 bit mode will not render out unity, but the Magix intermediate codecs don't have this issue. At this point I am stumped.
