What John says. Did you click the options button after selecting Quicktime Movie?

Did you install the proper R3D AMA plugin? It’s a separate install these days. Without it, you are just linking to the QT files, not the R3D’s.

Can you roll back to QT 7.7? Did you use the installer from https://www.avid.com/codec?

[Job Ter burg]

Seems to depend on configuration. Also: use new user settings. 5.5 and 6.0 are very different.

After installing, if you open QT Pro, and export a QT movie, you would find the Avid codecs between the other codecs.

My favorite test chart by the way:

Import this into your Avid without modifying levels (choose 709), and you will have a great test chart with legal and illegal levels. Nice one to carry through your workflow and see if you can preserve accurate levels throughout.

Ronn, yes, sorry about the sarcasm.

Your examples, however, do show a gamma shift.

Your DNxHD appears to have been exported with stretched levels, so it runs 0-255 (not broadcast legal). The H264 appears to be broadcast legal. Rescaling one of them (I corrected the DNxHD back to 16-235), and comparing two frames shows quite a different gamma, most notably in the details in the sky of the H264. (BTW, I’m using AMA to link to your files, and use Source Settings to compensate the DNxHD back to 16-235).

But even at desktop level, the very first frame of your spot demonstrates the issue. The symbol above the World Cup logo looks fine in DNxHD, but is only half visible in the H264 (where it blends to full white with the ‘hot’ sky).

The issues with QT and some codecs (ProRes, H264) have been popping up everywhere on forums like these over the past few years.

I haven’t managed to export to H264 without any gamma shifts, but there was much less of a shift when using the Main Concept H264 encoder that is featured in Squeeze.

IMO, the best way to export a file for broadcast, with correct levels, is to avoid QrapTime, and export as Op1A MXF (Export to a virtual XDCAM device).

Then you must be the only one in the world not suffering from issues with Apple’s H264 codec.

QT Pro and H264 will give you a very severe gamma shift.
