Expected behavior with Premiere's new Wide Gamut color setup?

I am excited to make use of Premiere's new Wide Gamut color setup but trying to integrate my older colour workflow has me confused.

My sequence is set to Wide Gamut (Tone Mapping) and I am using Panasonic v-log footage.

Selecting Panasonic v-log/v-gamut colourspace in the source clip results in an expected behavior- the footage looks the same as if Panasonic's official log-to-rec709 LUT is applied, but when corrections are made in Lumetri, it retains the benefits of the wide gamut- better highlight recovery etc. Perfect.

However, overriding a source clip to rec709 and adding a log-to-rec709 LUT seems to remove its Wide Gamut benefits (highlights respond like the sequence is rec709). Ok fair enough- so the most logical move would be to disable input color management and then apply the LUT...

But disabling input colour management (and no LUT) on the source clip immediately makes it look like it once again has that Panasonic v-log/v-gamut colourspace turned on (though the curves are slightly different). Is this expected behavior?

With no input colour management and no LUT, I would expect the footage to look exactly like its RGB information (ie what it looks like in VLC player) ... so what is happening that I don't understand?

To anybody else who comes across this- I discovered that in order to get Wide Gamut responsiveness on LUTS you can use the 'Creative' LUT option field and select ACEScct as the Color Space.

Source clip and Sequence can remain as rec709 but you *must* enable 'Colour space aware effects' in the *sequence* settings for this to work.

You cannot use the Basic Correction option field or the newer Lumetri Colour settings field to achieve this.

For many people, following Neil's suggestions about how to setup colour management, with auto-detect log, is the better option- but if you have LUTs you want to get a wider responsiveness out of, this is the only way I've found that currently works.

There's a whole series of options ... such as whether you have auto detect log on, auto tonemapping, and even whether you have tonemapping before the sequence CM or for the sequence.

So what are the settings in use for auto detect log, auto tonemapping, and whether or not you have input tonemapping on for the sequence? Do you have the Wide Gamut Tonemapped, Limited tonemapping, or no tonemapping?

To get 'full' log look, use the diasble CM option up top. Or you can have Premiere auto-detect log and apply an algorithmic tonemapping, either to the clip itself with sequence Input Tonemapping on, or to the clip as part of the sequence CM, where it's after any color corrections in Lumetri without the sequence input tonemapping.

The options are almost bewildering ... and I could go deeper into this rabbit hole so easily ... lol.

Everyone's mileage always varies ...

Hi,

Since you have disabled the input color management, Panasonic/V-Log gets to ACEScct timeline unconverted. But there still an output color management that still converts from ACEScct (wide gamut ) to Rec 709 (output color space).

If you want to use LUT for the workflow, you can disable color management at the sequence level. However, if there still an output color management that still converts from ACEScct (wide gamut ) to Rec 709 (output color space)

I hope the response helps guide you. Let us know if you have further questions.

Thanks,
Kevin

Thanks Kevin,

Disabling color management at the sequence level and applying a LUT seems to remove the benefits I was getting with Wide Gamut (Tone Mapping), the highlights respond differently for example.

Is this because LUTs designed for rec709 are clipping information that would otherwise be usable in ACEScct?
