Hi guys, 

I'm having an issue with the latest version of Premiere Pro.

When I apply one of my LUT's, the playback get's a lot lagged. I used the export LUT plugin for Lightroom to create my LUT and it always worked fine until now. Any ideas on what it could be?

 

Downgrading again to the previous version.

 

Thanks in advance!

What's your hardware? The newest version does push gear harder.

Hi there Neil,

I have the latest MBPro, I9 8 Core, 16GB DDR4

AMD Radeon Pro 5500M 8GB.

 

The factory LUTs that premiere provides are ok, but when I put my LUT it got latency...

Where are you parking that LUT/s on disc? I hope in the following locations ...

 

And if you could upload one I'd be happy to test on my system.

Previously I've always used the 'Browse' method on the creative Lumetri tab, but I already tried also in that exact location.

You can find in here one of the examples.

Thank you Neil!

I setup both the Technical and Creative folders for those locations, and have an icon on the desktop for rapidly accessing those folders to add or subtract LUTs.

 

I also rename all LUTs I use ... a prefix, so that they are

 

1) ahead of all the included ones as I can only recall using an included LUT once;

2) organized by how I will use it.

 

For example ...

 

01 A Low-sat neut

01 B norm-sat neut

03 C BRAW medium contrast high sat falloff

 

Like this. In alphanumeric computerese, these will be the first things seen in the list. And will be organized within the browse proces as I wist them to be.

 

Now ... I downloaded and tried that LUT on several clips on my 6 core i7-6800K 3.2Ghz rig, 32GB of RAM, GTX1060, with both BRAW and high-data rate mov files. No slowups at all.

 

Wonder what the issue is on your machine? That's ... odd.

Hi there Neil, 

Upgraded yesterday for the last version of premiere pro and it still isn't smooth 🤷‍:male_sign:

Can you send one of your installed LUT's for me to test? I think it can be the LUT file with some issue with teh last version of premiere 🤷‍:male_sign:

 

Thank you!

Which version of Premiere were you running when you tried the OP's LUT? I'm experiencing the exact same issue described in this thread - I've even tested on two different workstations and the problem arises on both machines in Premiere versions after 14.3.1, including the recent 14.5 update. It doesn't matter where the LUTs are located nor what type of codec it's being applied to (in my testing, at least).

Well this is puzzling. I can't replicate on either my laptop or my desktop, both run slick & normal with various LUTs applied.

 

Win10 both ...

Thanks for confirming that Neil. Hmm... this is odd.

 

Can you share which Nvidia driver your currently running? Also, I've linked to a LUT below - can you try that one? I know it's a heavier LUT, but it plays back fine for me on 14.3.1 (and previous). Oh and please test using the Creative tab in Lumetri, not the input area in the Basic tab.
