Interesting.
Windows doesn’t have to rewrap as you just flip the Nanoflash file wrapper to MXF or MP4…and record it that way.
Does the footage play in QuickTime player?

I would personally recommend exporting master clips of your finished projects and editing those (it’s useful to have a high quality master clip anyway).
If you’re importing dozens of edit sequences into one project and amassing all that source material, etc…it could be a pain in the neck.
It would drive me nuts to try to create a demo reel that way…too much source media to load/keep track of…

If the “default” media player is QuickTime X, you may need to install QuickTime 7.x…

It sounds like you might want to update a plugin or 3rd party driver like CineForm, AJA, BlackMagic, etc… Do you use anything like that?

It isn’t “eye-gougingly bad” as far as I know…
P2 creates names that make no sense to humans…Adobe has no control over that. The file name you give it will be evident upon re-import into Adobe, but Panasonic’s format insists on inventing something else for the OS-level filename.
What is the audio master setup on the sequence? Is it stereo? You would want multichannel for an 8 channel output.
(edit) Actually, I checked the documentation as I’ve never tried to master back to P2 as multichannel. Premiere Pro supports exporting 4 channels out (what the camera supports) to P2 when mapped A1-left front, A2-right front, A3-left rear, A4-right rear in a 5.1 sequence.

Does it also lag if you add the Adobe 3 way color corrector?
Colorista uses OpenGL so it does get some GPU boost…but it’s different than CUDA accelerated effects…

If you already have a graphics card that Premiere Pro can use for CUDA, any version of Premiere Pro pre-CC won’t utilize a second graphics card.
The RED decoder (like all video decoders at this point) runs on the CPU. The RED decoder runs on one core for one stream of footage. Your other cores may be doing other stuff, but since the RED software decoder is single-threaded, thus the clock speed of the CPU is more important than the core count when it comes to playing back RED R3D footage.
A solid GPU certainly makes a big difference as there are lots of color space and interpolation and scaling operations that the GPU picks up under CUDA so the CPU can concentrate on the decoding process…but if you already have Adobe-compatible GPU cards, then it’s likely bottle necking at the CPU.

The Quadro vs GTX card question comes up quite often.
A 10 bit color pipeline is critical for monitoring sophisticated projects…but of course a 10 bit display is needed to realize that benefit.
One other difference is that Quadro cards are built by NVIDIA only. GTX cards are built under license by a variety of manufacturers, and there very well may be small differences in components from manufacturer to manufacturer…
There’s also the matter of heat and power consumption, and the arrival of the Kepler technology has increased the differences in this aspect…most people tend to look at display card specs from the standpoint of processing cores and VRAM…so the GTX670 vs the K5000 makes a close comparison. The K5000 has the same amount of RAM, and an equal number of cores, yet max power consumption for the K5000 card in the spec is 122 watts.
The spec for the GTX670 is 170 watts…about 40% more power…for 8 bit color vs 10.
Cooling also needs to be considered…GeForce cards create heat…the GTX670 specs to operate at temperatures in excess of 200F degrees.
For many, these compromises may seem minor compared to the difference in purchase price, but different factors carry different value for each customer. In environments where noise and temperature are important considerations in addition to visual quality and speed, this is not the slam-dunk decision that it is sometimes portrayed to be.
If I’m playing Halo and I need to tolerate some fan noise and an occasional alien shields texture redraw error for a frame…then it’s an easy decision.
…however, my clients aren’t nearly as flexible about their logo animating in their commercials.

There are “scratch” files determined by the project…video/previews, audio/previews…and then there are cache files…location determined in the application preferences.
In the case of MPEG with embedded audio, the audio is typically de-embedded and made into separate files that can be processed more quickly during editing and listened to during scrubbing the timeline, etc. Those audio files are uncompressed I believe and can get pretty beefy.
You may want to try going into your preferences>media and click on “clean” media cache database…this should basically release any unused media cache files and free up the drive space, but use a new project to do this as Premiere Pro will think all those files are still in use if you open the project that created them to access the preferences…
