Thanks for the crosslink chmee.
To confirm - in the forthcoming builds of Premiere Pro CC / Media Encoder CC / Speedgrade CC the Mercury Playback Engine will support some (but not all) flavors of CinemaDNG footage created by ML tools, such as chmee's. ML cDNG import is a side effect of support for other cameras and Adobe aren't making a headline of it for obvious reasons, but it'll eliminate the need to bounce through AE or use the GingerHDR plugins. Instead of importing through Camera Raw, you will get a Lumetri quick-adjust dialog similar to the one for ArriRAW. Playback will be fully accelerated, I can scrub through 1080p footage on my relatively feeble laptop and play back in real time with a bunch of grades and effects slapped on. Disk read speed will be your only practical limit to playback smoothness.
Yes it'd be nice to import RAW or MLV files natively, but we have to be realistic - Adobe has close ties to the major camera manufacturers, and can't be seen to be actively targeting a 'hacked' format however good it is.
