Sony A7RII S-Log2 to AgX test footage.

Here's some test Sony S-Log2 / ITU709 footage, transformed to AgX and compared to sRGB LUT.

More about AgX:
AgX is a view transform that takes linear rec.709 footage (or stills) and forms a very pleasing looking image, by employing a couple of film-like traits, such as chromatic attenuation (a.k.a 'highlight desaturation') and special tonality, and dynamic range "compression" (incorrect term).
Made by no other than Troy Sobotka (same person who made Filmic Blender)

For AgX to work, you will need software compatible with OpenColorIO v2 (OCIO V2), I.e: Nuke, Blender, Olive, Houdini, Maya, etc. etc.

A good, baseline configuration to get you started:

Thank you Troy:

I'm really at awe. Of course with what you've captured, but also how AgX does its transform. It's brilliant!

It doesn't look like some attempt at making digital imagery look like film, instead I seriously can't tell that this *isn't* shot on film. Which I suppose goes to show how well the behaviour of film has been reproduced here. (Lack of film grain of course notwithstanding)

I'm glad you made a showcase for this! You're the only one I've found on YouTube showing how AgX treats photography, rather than some CG examples.

Hi, thanks to share your work on AgX.
What is the slog2 to sRGB LUT you are using? wouldn't be more interesting to compare AgX to some resolve CST with tone mapping and gamut compression? Or even to Sony LC709 LUT (at the end of the pipeline) which is made for post-production?

[pedrorrodriguez]

Loved your darktable tutorials, and this is also very interesting. Look forward to more videos on agx!

Great video! Do you know if AGX can be used in Resolve or if that’s coming in the future? I shoot 10bit V-Log on my Panasonic S5 and find it difficult to get natural looking colours out of it with film emulations, but this seems like a much better starting point for grading.

[kirillfeov]

That''s awesome! Could you tell more about the process of convertation? Is it the same as ACES?

[salarycat]

The footage looks awesome. Would love to know your process of converting f-log to agx.

The rgb looks better. What was the point here? You can get a smooth controls with davinci Wide Gamut or Aces. Also what is the AGX transfer function? Why would you compare a seemingly film look to srgb? Why not 1886?

Also upload in 4K, would be so beautiful.

So you figured out how to process 709 primaries with AgX!?

Are you shooting full frame now?
