Adjustment layer in premiere blend mode issues

I applied an ellipse mask to an adjustment layer, altering its color temperature. The adjustment layer was set to the overlay blend mode and positioned above a video clip in the timeline to achieve a specific effect. However, instead of only overlaying the masked color temperature, the adjustment layer is causing a tonal shift across the entire clip. Despite applying a mask solely for color temperature adjustment, the entire clip is affected. Does this make sense? Any advice on resolving this issue?

Hey Neil,

Thanks for the response. I understand (for the most part) that video editing is notably more labor-intensive in non-linear editing systems due to the fact that a single second of video consists of 24-60 frames. What had previously eluded me, and which you've kindly clarified, is the process of achieving a similar effect in PS using adjustment layers and the brush tool but in Premiere Pro.

If I understand correctly, an adjustment layer in PR applies all its effects to the track below, unlike in PS. I can employ Lumetri to mask in the effect, but can I also adjust the blend mode to overlay using Lumetri? As far as I'm aware, blend modes are only accessible in the drop-down menu for the opacity effect.

There are other means of getting places. The Track matte effect for instance. Alt-drag a clip up twice so the same clip is on 3 tracks. On top use a mask or Lumetri HSL key to select an area or hue.

On middle clip apply track matte, setting to take input from V3 by luminance. Now any changes applied in an effect on V2 is applied limited to the selection on V3 to the clip on V1.

Did you make the mask from Lumetri?

Certainly, regardless of the color settings, when I apply the blank adjustment layer above the clip using the overlay blend mode, it automatically impacts the clip below, even without any adjustments made to the layer itself. Are adjustment layers in Premiere distinct from those in Photoshop in terms of functionality?

The Lumetri effect and mask weren't applied to this layer. The main issue was the adjustment layer affecting the video clip below when set to the overlay blend mode.

Interestingly, in Photoshop, if I set an adjustment layer above my photo layer and set the blend mode to overlay, it won't affect the tone of the image, unless perhaps I apply a brush stroke to that adjustment layer. But only that brush stroke would be overlaid onto the photo layer below.

So I guess my follow-up question would be: How do I apply a similar effect using an adjustment layer set to blend mode like in Photoshop?

I've attached another screenshot of a Photoshop file as an example of the effect I'm trying to achieve in Premiere.

Having come into video post from a then-30 year career in pro stills, our first use of Photoshop was CS 4.5. We were early adopters of digital imaging in pro stills, and first used Lightroom in public beta 0.8.

Video is not stills!

That is a first thing you have to learn, like I did. Stills is designed around manipulation of one or maybe a batch of up to 20 images, right? Video ... is at least 24 images per second ... grabbed from who knows how many different clips on disc, with effects applied on the fly. The processing load is enormous and so the tools are very, very different because they have to be.

There isn't any "brush" typ effect in Premiere. Anything in an AL is applied to the tracks below the AL unless of course there is a mask on the effect in the AL. So you would probably need to use the mask in the Lumetri effect on that AL to mask where it affects the image.

Either that, or use the HSL Secondary tab of Lumetri to make a qualified key based on some combination of hue, saturation, and luminance, then use the controls in that HSL tab to change the image parts selected.

Everyone's mileage always varies ...
