Which LUTs did I use in an old project?Posted by André Mascarenhas on February 1, 2024 at 9:25 am
A client asked for a revision in a 2018 project. I opened it, all going well, until I realize that the adjustment layers I used for color grading were empty with no luts (either technical or creative). The image definitely looks straight out of camera.
Is there a way to see in the some record inside the project which lut(s) I used for that project so I can match the original look?

Can you remember whether you used system LUTs, or third party?
There may be a chance that Adobe when they allowed you to apply LUTs direct on to source footage, might have thought that this the future of the workflow – and once again not make it backwards compatible.
Although that does not quite sense with your description of the problem – but then Adobe works in mysterious ways.
The footage that you are applying the grade to, is that camera footage or something else?
Can you identify the camera used?
If so, is there a base LUT that you can apply to that, and see if that fixes the problem?
Alternatively, maybe ask Adobe for a 2018 version of Premiere Pro and open the project there.
There are smarter people around here, who might have a better answer – do watch out for them 😀

Thanks for getting back to me.
Indeed this might be the case with applying a base LUT directly to the source footage. I was shooting with a good old Gh5 back in the day and when checking the original footage, it definitely is v-log, but in my project it does have the rec709 look embedded, even though the lut is not listed under technical LUTs.
Fortunately, I figured out a workaround – one that is a bit sloppy but will work out for this client, who is not picky. I placed the final exported file on top of my edit, and I’m doing some croppings in the parts of the image where I need to place new graphic elements – mostly lower thirds. I’m doing some basic matching of looks – it’s barely noticeable 🙂
Probably downloading Pr2018 could be a solution too! Will keep this in mind for future projects.
Thanks for your help anyway!

Good to hear that you are sorted.
At least GH5 is a common format camera. And, you should hopefully be able to find a matching Panasonic LUT, or someone who has created one that you can download for free.
On complex projects that might come back to haunt you, for anyone else out there also following this thread, it is always good to have a ProRes or similar Master File format with a clean version (NO GRAPHICS), and ISO audio for each track(s) containing V.O., I/V, Nat, SFX and Music.
Good Luck with the project.

Yes, the problem is that I’m still not sure what creative lut I put on top of the rec709 lut… Anyway, I got it sorted for this one.
Indeed the workflow you suggested should be essential common practice – will make sure to do it for my recent and future projects. Thanks again!
