VLog GLSL shader

[Aurora Films]

For those playing around with Vlog footage here is a shader to confer from Vlog Vgamut to ACES.

I have included a some options to either not to gamut conversion or to output Linear Rec709... just need to comment/uncomment the proper lines.

Using color science from Panasonic: https://pro-av.panasonic.net/en/cinema_camera_varicam_eva/support/pdf/VARICAM_V-Log_V-Gamut.pdf

Played around with some Panasonic GH5 footage from Neumann Films with good results

Have fun!

PS. Im sure SGO will include VLog conversions in the Unicolor in upcoming releases, so not recommended to use this in production.

Played around with this a little more. Some cleanup done.

Attached a new version of the previous one, another one  with straight Linear (no gamut conversion) and another outputting Rec709 Gamut.

Also attached a timeline with one of the ways I would use this. 

Hope you find this useful.

Did you really color grade that in 2 minutes? It looks neat!  Thanks a lot for sharing ?

[Aurora Films]

Thanks!

We'll.... maybe 3 min ?. Colorspace transformations and Film Lut get you a long way. The is just primary balance and some (Fixed Hues adjustments on the 2nd shot)

Hope all goes well at NAB
