Ah, Gotcha! Were you using auto on levels or curves? Or both? I understand putting many frames into one big image, but would that be equivalent to finding the average of 10 when 3 are more like "X", 2 are closer to "Y" and the last 5 closer to "J"? I'm sure you considered this already, so what was the conclusion you came to? Related is, how was the previous (DVDv3) methods used (in comparison to this new method), which incidentally is clearly nowhere as good as this new method..

I'm not criticising the new approach, just trying to understand the rationale behind the methods used.

I used auto on curves, with zero on clipping of course. Of course it wouldn't be equivalent of the perfect average, but on the other hand, it will almost always find the most obvious tint and fix it.

As for DVD V3 I don't know since I wasn't involved back then.

And your idea with Lightroom is a very good one, but we won't go for such an advanced approach. We'll keep our color settings as they are and work from there. Feel free to start your own project! :)
