Re: [Avid-L2] Re: Epic 5K 4800x2700 5K Footage and Frame Flex for Transcode?

 

"You now created 4800x2700 MXF media. Using FrameFlex, you could theoretically use those extra pixels when blowing stuff up."

That's what I thought that setting would do but then how come when I take one of the resulting .mxf files into MediaInfo it lists the dimensions as 4096x2160?  I expected to see the dimensions mirror the actual source of 4800x2700.  So I don't really know if Avid is really creating DNxHRHQX media that is truly 4800x2700.

So now I have transcoded the same clip twice once a Project Raster Size and once at Source Dimension.  I added the column "Raster Dimension and that column shows the different settings.  Project Size yields 4096x2160 and Source Dimension yields 4800x2700.  But both clips look identical in an HD downconvert of display on a UHD HDMI fed monitor.  So clearly Avid changes some metadata but the image appears the same so what is this setting really accomplishing?
