Gaussian blur - auto tracking extremely slow

Question

Hello everyone

I'm using PP 24.1.0.85. The program runs smootly editing 4K footage but when I add Gaussian Blur and click on "track" it takes about 2 secs to track 1 video second. I'm tracking 1 face and it pretty small compared to the video itself.

My main editing station is a i9-13900k, 64 GB ram, rtx 4090, while my notebook is a Lenovo Yoga Pro i9-13905H, 64 GB ram and rtx 4070 Mobile. I'm mentioning both configurations because there's literally no differences in tracking between the two machine. Monitoring via hwinfo and task manager, my GPU sits at at about 10% while the CPU is at 20% (top load) and the temperature are around 60° on my laptop and even lower on my pc.

Am I missing something obvious here?

Thanks!

Thank you very much for your reply. I will try with the next clip. Unfortunately it looks like there's a bug in the s23 which prevent the frame rate to be consistent. Otherwise that would be the best option I guess.

Once again thanks!

Most phones record video as VFR, not just yours. iPhones do it also, as to many GoPro and drone rigs. All of it really should be converted to CFR for use in editing.

And your S23 isn't showing a bug, it's by design. My S22 Ultra of course does exactly the same thing.

So ... use Handbrake or ShutterEncoder, two free utity apps, to do the conversion to CFR as listed above. Then import the resultant clips into Premiere.

What format/codec are you working with? That's another issue that is part of this.
