accelerate stabilizing 4k-footage in Premiere Pro (or AE)?

Hi,

I recently filmed with my smartphone some B-roll footage of a friends wedding, nothing too fancy but still needed because the photographer missed this stuff.

Luckily I filmed this in 4k60 (3840 × 2160) and despite my thoughts the resolution gives us atleast the possibility to pan around in the frame.

My prob: using the warp-stabilizer even the analyzing takes hours for a 3000 frames clip, what makes me wonder most: it seems to only use 1 of 4 CPU-cores and is not using the GPU at all, despite that it is one of the GPU-accelerated effects. I know, a i5 2500k@4.2GHz, 16GB RAM and a GTX970-G1 is crap today but seeing the GPU is not used at all and the CPU only using 1 core.... Premiere Pro CC should do better in 2019.

Aside from the technical question: can I use a scaled down version of the video to analyze the motion and apply the ststabilizing to the highres-footage somehow like it could be done in AE? Speaking of, I tried to import the video in AE but everytime I end up with a 10second part of the clip and I can't see what I do wrong there.... uhm.... Help?

try proxies:

Warp Stabilizer uses the original clip and not the proxy to stabilize in the timeline.

WS is cpu intensive and also your machine is somewhat underpowered for 2019.

Honestly... this does not respond to my questions, though? Why is WS listed in the GPU-accelerated list if it is not using the GPU at all?

And there is no faster solution to track / unshake camera-shake?

The hardware-requirements are funny because Adobe does not explain why you would especially need a 6th or 7th gen Intel-CPU. Aside from my 2nd-gen i5 2500k every other recommended specifications is met. And aside from 4k-footage I never witnessed any bad lag so far. And as a company like Adobe, they should optimize the software to run on a reasonable number of different hardware-configurations.... especially since they target also the home- or pro-sumer with their "rent-a-Photoshop" program.

Premiere Pro is not targeted for the "home" crowd. That's what Elements is for.

And they are working on gaining stability by designing for a narrower range of gear, and working better and more stable on that selection.

It is very CPU-centric, it's the heart of the processing chain. Everything else on the computer is used to feed the CPU within their design, including the GPU. So for GPU-accelerated effects like color or WS, the CPU uses the GPU for what the GPU is used for, and as the CPU is ready or that data.

A low power CPU takes a long time just to get bits of work out for the GPU to do.

Sometime in the recent updates I swear Warp Stabilization got a fair bit slower.  That said I have an 8-core (16 thread) Ryzen 7 cpu and it is currently using all 16 threads to analyze a 40 second 4k clip for me.  It is actually analyzing as I type this.  My GPU is at 1% utlization.  I think the GPU is used for Rendering out during Export, not during analysis.  But I'm just guessing off anecdotal evidence.

Analyzing is done on the cpu, stabilizing on the gpu.

A 3000 frame stabilization is not an easy task, even for today's most beefiest machines, especially in 4K 60fps.

Do you intend to use the clip in its entirety? If possible, cut away to other camera angles, so you can break up the required source clip, preferably covering up the parts where the movement is biggest in the clip. After cutting up the clip, stabilize the resulting cuts.

Instead of relying on Warp Stabilizer in PPro, you may also consider trying this in After Effects.

Trial & error, see what works, but don't simply blame PPro for failure of proper hardware or asking it to perform a 3000-frame miracle for you.

Jumping back on this. I have a threadripper 3970X 32 core cpu and two 1080ti's until nvidia releases its 30 series. 

Currently takes 10 minutes to analyze 25 seconds of footage. THREE percent cpu usage from after effects. There is no reason they couldn't properly split the workload tracking multiple markers on each frame across multiple cores. People saying your cpu is underpowered, try using proxies, and warp stabilizer is cpu intensive do not understand the problem. The problem is Adobe leaving themselves in their own dust as they steam ahead without giving proper thought to updating their old tools.
