[Avid-L2] Avid DNx Uncompressed vs 1:1 10bit

 


In the just released MC 2018.9, there is a DNx Uncompressed 'CoDec.'  Anyone have insight on the difference between 1:1 10b (100% Uncompressed, 10-bit 4:2:2)?  is it only that the timeline goes up to 32-bit floating MXF (both YUV and RGB) from its native 16-bits?

The documentation simply states:

With the introduction of DNxUncompressed, it is now possible to import, render, transcode and mixdown at uncompressed quality. This allows you to generate media that preserves the full quality of the Timeline (currently the Timeline is 16 bits maximum). DNxUncompressed is available at any raster dimensions (HD, 2K, UHD etc.)


The new options are:

  • For YCbCr projects: DNxUncompressed YCbCr 4:2:2 32-bit float MXF

  • For RGB projects: DNxUncompressed RGB 32-bit float MXF

n At this time, DNxUncompressed is not available for export operations, including AAF (embedded), QuickTime (same as source, reference, custom), XDCAM Export, Send To Playback, or AMA File export.

For exporting a project at highest quality possible, we recommend using DPX at 16 bits.

n DNxUncompressed is not currently supported in an Interplay environment.
