Re: [Avid-L2] Re: Sony F3 s-log lut

I can concur with Chris' point.

I off-lined a national spot involving a great looking early morning cattle drive with cowboys and the rising dawn sun. As such, it was very contrasty and lots of it was fairly dark, (at least in the one-light telecine that I received, back in the early-1990s). I cut the spot together and was pretty proud of it. Then I went to the color correction session (back when agencies still paid for editor's and DP's to provide input).

The D.P. was furious at me because I'd left out some BEAUTIFUL shots. Now obviously editing isn't all about just putting in the best shots, but I had been going from a pretty crappy one-light and when I finally saw a REAL grade of the shots, I had neglected some truly spectacular footage because it just looked unusably dark to me. They were able to push enough light through the negative in the real color correction to bring out some great looking shots, but the one-light just looked SO dark. The range of light levels in the course of the shoot was huge and they basically corrected the one-light for the middle of the hour-long shoot, making early morning stuff fairly dark and later morning stuff look a little blown-out. Almost everything that I used in the spot was from the middle of the shoot.

Some of that was my inexperience cutting from one-lights (plus no NLE CC tools, back then). Some of it was from a cheap one-light. And some of it was from the DP getting her ass bailed out by a great final color correction. In her defense they were trying to really run and gun a lot of footage during a single "golden hour" shoot, so exposures were probably set every few minutes even though the conditions were changing much faster than that.

Processing all corrections in at least 16 bit 4:4:4 no matter the colorspace of the source clip should be considered. This should not be a special mode or timeline setting. Even though it should just work this way all the time, a project setting would be ok.

I work on it for a while, then decide to look for an alternate take on a shot, and I open it in the source monitor, and that alt take will look boring and flat. That simply influences the perception of that take (in a negative way), and that's a pretty bad situation in offline.
