Not able to apply a LUT to the clip

So I'm trying to apply a LUT to clips on my timeline but the only LUTs I can apply are the ones that come with Premiere. If I apply any external LUTs they don't affect the video in any way. It says that it has the LUT chosen and applied but it does nothing on the video. If I change the LUT to one of the pre-loaded ones, then it works fine.

The LUTs I'm trying to use work fine on DaVinci and FCP.

Am I missing something?

The 'barbie' didn't do anything in Resolve or Premiere. The other didn't do anything in Pr but did in Resolve, so I exported that from Resolve ... and it worked fine in both the Basic and Creative tab LUT slots of Premiere.

Rec709 Fujifilm 3513DI D65.cube is in the wrong format to work with PPro. For whatever reason, Blackmagic decided to use an almost identical LUT format to Adobe with one tiny difference that makes them incompatible with us. Luckily LUT files are quite easy to edit with any plain text editor like BBEdit, and the syntax fix is trivial in this case.

Open up the LUT in a plain text editor and find the line that specifies the input range. LUT_3D_INPUT_RANGE 0.0 1.0
If it specifies 0.0 to 1.0, Delete the whole line. This is the default range for LUTs and is not needed.
If it specifies something other than 0.0 to 1.0, copy those numbers using the following format, making sure to copy the numbers 3 times. The first number is the MIN and the second number is the MAX
- DOMAIN_MIN 0.0 0.0 0.0
- DOMAIN_MAX 1.0 1.0 1.0
After you make these changes, simply save the file and they will work with Adobe.

----- Blackmagic LUT format example
LUT_3D_SIZE 33 LUT_3D_INPUT_RANGE 0.0 1.0
---- Adobe LUT format example

LUT_3D_SIZE 33

DOMAIN_MIN 0.0 0.0 0.0

DOMAIN_MAX 1.0 1.0 1.0

Barbi_look.cube file seems like to be a bit messed up too. In this case the entries do not have the same number of decimal places. It shouldn't matter, but after I cleaned this up in Excel and saved it as a space-delimted file it appears to work. The adjustment is odd, though - the very brightest parts of the image go pure red. I'm not sure if this is the intended look, but at least it's is doing something now.

lehestro,

Where did that LUT come from?

This used to work for me, but no longer seems to for some reason. I wonder what I'm doing wrong. My LUT begins like this:

LUT_3D_SIZE 33

0.0000000000 0.0000000000 0.0000000000

dkelso12,

Not all LUTs are usable in Premiere. You say this is a BlackMagic LUT, which one? And could you upload it so I could test it?

As to LUT placement ... do not ever put LUTs in the Premiere program folders. Period. Use the following chart, and Premiere/AfterEffects/MediaEncoder will all automatically 'see' the LUTs and apply them by the LUTs name. Note: you do need to add the Technical and Creative folders to the following locations, then park your LUTs there. Technical will be seen in the Basic tab's dropdown, Creative in the Creative tab's dropdown.

I add a prefix of a number and letter to my LUTs, so they show up organized and ... first, ahead of the built-in LUTs which I think I've only used like twice. So my LUTs are 'named':

01 A Low-Sat Mask

01 A Shadows Mask

01 A Highlights Mask

02 A Johnson ....xxxx

02 B B17 xxxxxxxxx

etc.

ive created lut folders and used these luts many times. now all of a suddent premiere says it cannot load the file. so there is nothing wrong with the luts, since they have been used successfully many times.

You also gave where to save the luts, but those folders dont exist. you go to users/user name/ then there is no library folder. ive tried this on both my macbook and imac.

That's Adobe's chart. I'm a PC user, so I can't say much about internal Mac issues.

Although those folder trees for Mac have been used by many for several years now. Strange your Macs don't have a Library folder.

Hey, I am also having this problem with Premiere, when I got to add any LUTs in the aren't premiere's own I get this error message 'a low level exception occurred in lumetri color aevideofilter 14' and it renders lumetri color completley unusable. I had a look inside the .cube LUTS I want to use and none have an Input Range Line, they all begin with LUT_3D_SIZE 33 and that's it. No idea how to make them work...

I'm having the same issue. I'm trying to move a Blackmagic LUT over to Premiere. When I click "browse" to import the LUT I get an "Invaild file: Unable to load selected file" message. But when I move the LUT into the LUT folder for Premiere it just turns my footage into a red and white checkerbox. I've tried adding and deleting the suggested lines. But does not seem to work. Any suggestions?

Tried on a handful of projects and it doesn't work in any of them...

I've tried using the LUT on the Creative slot as none of the non preloaded LUTs show up on the Input LUT menu.

The LUTs are on the Library>Application Support>Adobe>Common>LUTs>Creative

I can choose them at the Creative tab on the Lumetri Color window, but it has no effect on the clip.

Where is the LUT stored on your computer, and how are you accessing it?

I also tried copying them into every LUT folder available (inside the Application folder, in the user Library or in the overall Library) with no success.

They show up on the Creative tab, I can choose them, but it doesn't change anything on the clip. If I change to one of the preloaded LUTs then it works fine.

The LUTs I'm trying to use are .CUBE

Hmm.... That's weird. I haven't had issues with .cube LUTs before... Maybe test it on a completely different clip with a new instance of Lumetri (and maybe a new project) to see if it's an issue with that clip/sequence/project. Also, make sure you don't have the Disable All Effects button enabled. Sometimes that's hidden from the Program window so I don't notice and then I'm pulling my hair out trying to figure out why effects aren't working.

Are you using .cube or what format? If it doesn't work on the input LUT slot, you can always try the Creative LUT slot in Lumetri.
