VFX workflow from CS5 Premiere

I would like to export clips from my Premiere CS5 timeline for VFX work. The reasons for the export is to only send the frames needing modification and to reduce the size for sending files across the internet. I am using Windows 7 64 bit and would like to keep the highest quality. The method I am currently using is: File > Export > Media. Choose Format: CineForm AVI File, RGB 4:4:4, Film Scan 2, I-Frames Only. Size info is 2048x1152, square pixels, 23.976 fps, Progressive.

These settings create an AVI file as expected, but the associated LUT is no longer there. The color changes seemed to be baked in. I can add additional color correcting to the new AVI, but I can't put it back to the default RAW settings.

My questions are: What is the highest quality way to export a video file from a Premiere timeline that started out as a RAW 2k file from a Silicon Imaging SI-2K camera? Is there a better way to grab a sub-section of a clip so that you can keep the associated LUT?

Thanks

Hi Bergen,

I was doing something similar a few days ago. In my case I was changing from CameraRAW to FS2 to try and achieve faster playback, not preserve file quality. I noticed that the color and LUT information that I had applied to the RAW was baked into the new FS2 files. My solution to this was to undo all the color and LUT info before exporting the FS2 files. A simple way to do this is create a vanilla database, that has no color information associated with your clips, activate that DB, and then export.

Create another database for your FS2 files and redo your color correction.

You will end up with 3 databases, one for RAW, one for Export (virgin) and one for FS2 files. I am still experimenting with this method...
