Blackmagic Shuttle DNxHD issue

[Jay Bloomfield]

I doubt that this will help with those issues, but the most recent version of the codec is 2.3.7:

Thanks. I’ll give it a try.

I’m running MC6.01 with the latest DNxHD codecs on a PC. Importing DNxHD files recorded on a Hyperdeck Shuttle 2 are shifting the gammas incorrectly. This happens whether you use the DNxHD direct or QT wrapped DNxHD recording method.

Bringing in the QT wrapped DNxHD by linking via AMA does not help. And the ability to change the range within Media Composer is greyed out for Quicktime DNxHD linkage.

BMD has yet to respond to this problem. They seem to be ignoring it.

[James Hughes]

So it sounds like BM have not implemented the codec properly into the Shuttle.
Surprise, Surprise, that’s very unlike Blackmagic to bring something to market too early…… NOT….

Most of the BM gear I have is OK but there’s always something that’s not quite right.
I guess you get what you pay for.

Come on BM… Sort this out please!

Have you tried updating to Adobe Premiere Pro 5.5.2?

adobe premiere? no!
I’m importing files into Avid media Composer 6.01 or Davinci Resolve. They both show the same gamma shift.

Kristian…
FWIW, there is quite a detailed explanation of how the DNxHD codecs work in the following user guide from Calibrated{Q}….
