The initial description was my intended use for this project. However, the color information just wasn't there in Grindhouse to do a quick and dirty color correction. It would have required far, far more time that I sadly don't have.

Instead, I settled for using Grindhouse to adjust the colors of Despecialized. While the specific color information I needed wasn't in Grindhouse, it provided an excellent source for the theatrical contrast and saturation settings, which brought out some of the depth and detail.

Essentially, as far as I understand, the RE:Match filter applies the LUT concept on a deeper level. You provide a source for the filter to use as a reference. The analysis is then applied to the video you are color correcting.

Since Despecialized is already GOUT synched, I used the script from the Gout SYNC thread to match up the two video files. I then set the RE:Match filter to Match Every Frame mode. That way, every frame that corresponds between the two different versions are matched for a very direct frame by frame correction.

Since Grindhouse has multiple spots with excessive red fade, I did have to drop the amount the correction was blended a bit, and you will find, specifically in the Dagobah scenes, that some of it is still is there.

Either way, I feel that it represents a near best of both worlds :)
