Many thanks to betty for the heads up and to @rylandjones for the tweet!
Ryland Jones is based in Los Angeles and works as a cinematographer, colorist and he also does VFX/Motion graphics. He tweeted about 2 hr ago that Keanu Reeves was talking to him on set today about the LUTs they were going to put on the footage.
A quick google search reveals that LUT stands for Lookup Table and their use appears to be involved in color grading on film. You can read more about LUTs here.
It is not clear what footage they were talking about.
Update: He is definitely back in LA. Someone tweeted seeing him this morning on the freeway. It made her day. Thanks @Steph_2718!
