Warp stabilizer doesn't work (really slow) if applied after Lumetri Color Correction

[Alberto Bedin]

When we apply Warp Stabilizer on a clip where there is a Lumetri Color effect it takes forever to analyze the clip.

Step to replicate: 

- Import a h265 10 bit 420 3840x2160 clip into premiere.

- Put the clip on a 4k timeline and apply the lumetri effect with a LUT. You can also right click on the source footage, go to modify -> color -> override media color space -> select a LUT such as Panasonic vlog.

- Now apply the Warp Stabilizer. It takes hours to complete on a 5 seconds clip.

If you apply Warp Stabilizer without the color correction it is really fast. It takes 10-15 seconds on a 5 seconds clip. 

Now this is another really HUGE PROBLEM: if you apply Warp stabilizer and then Lumetri color, it's fast. But if you save the project, close Premiere and reopen it, the playback of the stabilized clip is REALLY SLOW.

Render and replace the original clip is impossible (we have hundreds of clips). On previous versions of Premiere it was working.

Specs:

Premiere Pro 24.6.3 (same problem on 25.0)

Intel Core i9 13900K

nVidia RTX 4080 Ti founder edition

64 GB of DDR5 Ram

Windows 11 up-to-date

Video drivers up-to-date

Hi, @Alberto Bedin,

Thanks for the bug report. I'm not a developer, but while we wait for them to respond, see these articles by a plugin developer, Neat Video. They concern effects' order in the stack in the Effect Controls panel and also in the conceptual render order pipeline. You can get varying results by changing the order. This is true in other NLEs, too. At least FCP used to be that way too.

Is the Warp Stabilizer in the default setting, or have you set it to "Synthesize Edges" or something similar? As I understand it, that can also affect quality and processing speed.

I hope this information provides some perspective. I believe the product team is aware of these issues. Sorry for the hassle.

Thanks,
Kevin

Hello Kevin, 

thanks for the reply. Yes, I'm aware of the importance of the correct order of the effects applied. But please note these important aspects:

1.  On log footage we need to apply a LUT on the footage (even just a REC 709) as the first step just to see it in a normal way. Think about the modify -> color -> override media color space -> select a LUT workflow. It has the same bug.
   
   
2.  Warp stabilizer works better on high-contrast clips because it can find tracking point more easily. Please also note that AE says that "Warp stabilizer is applied ignoring the order of the effects applied". Maybe it is the same for Premiere. As a prove of this on my original bug report I said that if you save and close PR, than you start it again, the playback is choppy even if Lumetri Color is applied AFTER the Warp Stabilizer.
   
   
3.  "Is the Warp Stabilizer in the default setting, or have you set it to "Synthesize Edges" or something similar?"
   Default settings, just put in on the clip.

I have a brand new maxed out M2 Ultra Mac Studio with 192GB of ram and warp stabilizer is running painfulyl slow. I never remeber it running this slow, maybe it's a bug with the new Premiere Pro 2025 update.

I'm trying to stabilize some 30-45 second drone shots that were shot in 59.94fps and it's taking 25-35 minutes+ to do every single one, if it doesn't crash all together. I just can't seem to understand how something as simple and trivial as warp stabilizer can be this unoptimized.

I put the same clips into Davinici resolve and they take the normal 2-3 minutes at most. All these "small" issues with the way Premiere runs and opperates contiually pushes me away from using. How can I possibly not use warp stabilize on some drone shots without having issues? It's almost laughably bad.

Hi @chase_7612 ,

Welcome to the Premiere Pro forums! We are glad to see you here. We need a few more details to try to help with the issue. Please see, How do I write a bug report?

Thanks for submitting your bug report. I hope we can help you soon. Sorry for the frustration! 

Thanks,
Rach

Not sure what more information you really need here. Warp stabilizer is runnning incredibly slow. Slower than I have ever experience before, especially on the new 2025 update. I'm happy to try to provide you more information if you feel like it's necessaey but I don't. It should not take 30 minutes to analyze a 30 second clip on a M2 ultra Mac Studio with 192 GB of ram.

same here. Also using Mac M1. After the update it's super slow! The Footage is RED RAW. 

[Alton232810867xy3]

I'm having the same problem. '21 Macbook Pro M1.

What used to take 5-10 seconds to stabilize is now taking a few minutes.

[Alton232810867xy3]

Update to my comment. It seems to be working a lot better now. Not sure why.

Has this issue ever been resolved for any of you? It's so painful how bad this software performs...

HI Alberto,

I might be old and resolve issue - and I hope so. But I'm writting the solution here for everyone to see: premiere and its warp stabilizer works really bad when lumetri color manage your log footage. It's a 100% premiere pro issue, and not you doing the wrong thing. 

If you use warp your footage in "preserve RGB" it's as fast as it gets. I hope this is going to be fixed. (Mac M1 ultra 64gb).

[Alberto Bedin]

Hello Adrien,

thanks, yes I can definetively confirm that using warp in "preserve RGB" works fast. The problem is that everyone would like to use it even with the new color management color-mapping. I hope they fix this too! (Windows 11 64 bit)
