Yes, I tried that first, but it didn't work for me. The mask stayed relative to the layer it was applied on.

If you look down the comments thread Robert, you'll see a couple of other workarounds I came up with that might help. The comment starts with the text "WORKAROUND TIPS!"

Adobe reps might barely ever participate on uservoice and for the most part simply ignore our requests, but that doesn't stop us users from helping each other with our workarounds in the comments section! ;)

Oh, didn't see that. But yeah it's far from a great solution. However, I simply first make sure everything is in their correct place and only then I nest it. It saves time for now.

I pointed out that work around in my original post Robert, but it's a horrible option since any Motion adjustments made to the nested clip are made out of context of all other visual elements in the main timeline. The bottom line is that Adobe should make their software FUNCTIONAL. The fact masking works properly in AE but still to this day never worked properly in Pr is clear evidence that the Pr team is composed of individuals who know don't understand the basics of video editing and/or they simply don't care about us users.

My best solution, nest the layer(s) you want the track matte to work on. (right mouse click, Nest)
A nested layer is of course back in the center again and therefor aligns with your mask layer.

For goodness sake, please.

Yeah, this needs to be fixed and ASAP. I can move the matte anywhere over the footage like a James Bond intro but moving the clip underneath moves everything. Completely mental.

This needs to happen! The order of operations are inverted to every other app.

Please fix this...

@Leonardo, I ask myself the same question sometimes. I do know of at least 1 real editor that beta tests Pr... myself. ;) But I'm just 1 person, just like every other person who voted here. That's why it's so important to collectively participate with our comments and votes in an effort to be heard.

I created a Facebook group to help us get heard: https://www.facebook.com/groups/premiereprofeaturerequests.

There are workarounds as I posted in my previous comment, but ideally this issue should be fixed once and for all.

Are real editors or designers beta-testing Adobe products?
I doing think so, otherwise this issue shouldn't have happened.
This is so basic!

PLEASE. This infuriates me so much.

WORKAROUND TIPS!

Until Adobe fixes this, there are a couple of easy workarounds:

1. Add the Transform and Crop effects to your clip (in that order, otherwise it won't work). Crop your clip to the dimensions of the PIP/window you want. Now adjust your clip's Scale, Position and Rotation using the Transform effect. Bingo, it works! You can now change the motion properties of your clip without changing the size/position/rotation of the 'window' itself! To apply both effects at the same time in the future, select them both in the ECP with your preferred settings (or before changing any settings at all), right click on the name of one of them and select 'Save Preset...' (see illustration).

2. Even easier, just add the Transform effect to your clip. Now mask your clip using the Opacity effect's masking tools in the ECP. You can create a rectangle, circle or any other shape you want. Now change the motion properties of your clip using the Transform effect. It works as well!

Hope this info helps!

This. Absolutely. I'm astounded at how many essential requests users make that Adobe just ignores. Obviously this would preclude some of us having to pay for After Effects, this is probably why they won't fix it.

However, Adobe...anyone doing work intensive enough to need AE will purchase it, the others will simply find workarounds. I have the full CC suite so I can use AE but c'mon, seriously, I'm sick of throwing my footage back and forth.

Does anyone know of a third-party plugin that provides proper track matting in Premiere Pro (i.e. the way AE does it, without resorting to AE or nesting)? Years later, Adobe still doesn't seem to care about fixing essential things like this that would make a world of difference to editors. :(

I spent hours nesting clips because of this

Here's an illustration to bring more attention to this issue:

It's a real shame this hasn't been fixed yet! Keep voting and commenting to get Adobe's attention on this matter!

well - I had no fun at all learning about this 'anomaly' - I'm doing the work around as you suggested Pierre, but it's not ideal and I'm certain that Adobe are about to fix this... since it's been two years since your post!

This issue was posted two years ago and still no fix. It is an incredibly aggrivating problem that should be easy to fix. This is terrible. I thought the subscription licensing was supposed to allow Adobe to fix issues like this on a regular basis, guess not.
