Mask tracking not working

[BlueMushroom123]

I'm running the latest version of Adobe Premiere Pro and everything works great so far except for mask tracking. It simply doesn't work. I create a mask (currently doing this in Lumetri color) and hit "track mask forward". The tracking progress bar comes up and nothing happens. No progress shows up and eventually I just stop it. 

Any ideas as to how I might troubleshoot this?

 Thank you!

Found a solution,

I deleted all media cache files: Preferences < Media Cache < Remove Media Cache Files

Works perfectly for me now- hope this helps!

Its Feb 2025 here, and I'm running Premiere Pro 25.1.0 (Build 73) on an iMac 3.6 GHz, Radeon Pro 575X with 64 GB of DDR4 RAM and the Sonoma 14.6.1 macOS.

Just hit the mask tracking issue where I could successfully 'track backward' the mask, but once I tried 'tracking forward,' the progress bar would fill up about 90% and then stop permanently. It was frustrating because I tried all other attempts to troubleshoot. I even tried the "delete unused media cache files" suggested here, but it did not work.

I finally got it to work by selecting the second cache delete option (shown in this screenshot). I closed my project and then selected the "Delete all media cache files (requires restart)" option. Upon opening the problem project and initiating the mask tracking, I was able to successfully get it done.

Hope this helps someone else out.

I found out that turning off the visibility of every other track in the timeline was then what allowed me Pro to accomplish the tracking function as intended.

I usually duplicate and superimpose the clip.

Add a mask from opacity and the effect I want to use (lumetri)

try to nest to clip you want to track and then, aply the tracking on the nest clip, worked for me

Am sorry for the simplicity, but to me worked save, closed out and enter again.

I hope works for you!
