Convert Rec709 to Slog2?

[pirandello]

Hi there,

Is there a way to convert a clip from Rec709 to sLog2? 

In DaVinci Resolve, I can add a Linear to sLog2 LUT, though it's not exactly a Rec709.
On top of that, how I would export such a clip? I'm thinking ProRes, but other than the typical sLog flat look, I don't think I can actually embed any particular type of information.

By the way, this task is not meant for me to gain any extra information in the clip, as I know I'm starting from a Rec709 clip, so I will only end up with whatever info comes from the source.

Any idea?
