Avid DNxHD codec garbage

[Seth Larney]

Michael,

Just letting you know, 8-bit fixed the problem, my bad!

QT's are now exporting fine from Scratch, however I can't for the life of me get Media Composer to do a fast import with them. I've tried every import and transcode setting in 'Media Creation' with no joy.

Scratch seems to have the same QT export limitations as Redcine.

Any thoughts would be greatly appreciated!
Thanks,
S.

I guess the fix didn't make it to todays new Redcine release?... (still get garbage) . Just askin.....

Hey cws,

I think the fix is coming in the form of a new Avid codec download..
Cheers,

There is no re-encoding step if you encode to a QT wrapped DNxHD codec in the first place - that is why the codec exists. During import, it will unwrap the QT and move the essence over as MXF. No re-encoding. If you chose a different data rate or codec during import that the one in which was encoded, then like any system, there will be a decode and encode to that format.

On the topic of the garbage frames, we were able to identify and fix the codec on the PC to create proper images. It is getting wrapped up and a new installer will be available shortly on the Avid website. I will post a message when it does.

Hey Michael,

Do you have any insight on the 'fast import' issue with both Scratch and Redcine?

That's the last piece of the puzzle for us.. DNxHD quicktimes are kinda useless unless we can fast import them.

Cheers!

Is this true of DS 8.4 as well?

We are looking into the Fast Import issue... no news yet. And yes, same for DS about QT wrapped DNxHD.
