Straying off topic but sorry, but I would
really advise against that workflow.
Lightroom was never designed to process CinemaDNG sequences. The database engine hasn't been optimized for tens of thousands of frames in a
temporary transcoding pipeline. It assumes you're permanently importing photographs into the catalog (so all that waiting around is while it writes hundreds of megabytes of SQL and preview data to disk that you'll never need again), and while the developments in Lr are nondestructive, the exports aren't. The point of using raw footage is to retain it for as long into the pipeline as possible, so for example you can change the white balance long after you've started cutting the dailies.
After Effects includes
exactly the same Camera RAW engine as is used in Lr, but in AE it's been integrated specifically to support frame sequences. No temporary files are created, your developments for frame 1 are automatically applied to all the others, and it's
completely nondestructive. ACR supports user presets, lens corrections, etc. and the only things missing in the ACR window compared to the Lr UI are tools which would never be used on frame sequences (such as healing brushes).
Bouncing through a Quicktime DI is also a very bad idea, as the QT engine isn't optimized for 64-bit platforms (unlike Ae and ACR). The entire point behind the DirectLink pipeline between AE and Pr is to avoid
any need for intermediates.
The 'correct' workflow at the moment, from an Adobe point of view, is to import the DNG sequences directly into After Effects on a 16 or 32-bit comp, apply import corrections (lens adjustments, whibal and detail) in ACR then grade the footage on the timeline. If you want to cut in Premiere Pro, simply drop the AE comps into a Pr sequence. Everything remains 100% nondestructive and x64-compatible.
All this will be moot when the update to the CC video tools collection are rolled out to the public, as you'll then be able to load cDNG sequences into Premiere Pro and Speedgrade. They've been delayed while engineering perform some additional tests, but they're due shortly.

nice workflow
Lightroom
Quicktime Pro (if you know how to get it
)
After Effects
really simple and cool...
