Question

Face Tracking extremely slow?

Hello experts..

                       Can someone please guide me about why the face tracking with detailed features is extremely slow (about 4-5 seconds per frame), and what particular hardware is responsible for this job? because I don't see any CPU usage more than 15% neither GPU usage. RAM is also fine. and i have M.2 nvme SSD.

so i can't see any reason why it should be slow.

The clip is 1080p only 30 seconds even i have tried with other formats and low resolutions also but i see the reason is within after effects not with the video clip.

I don't understand if this is only with my system or everyone has this slowness issue?

After all what specific hardware is needed to speed up this process?

My hardware is:

Asus X99 gaming board

Intel i7 6800K CPU

Nvidia GTX 1050TI GPU

Samsung 500GB M2 nvme SSD

Ballastix 32GB RAM

Adobe AE CC 2017

Win 7 64bit

Thanks.

    No wonder. Ae uses only 2 - 4 CPU threads at once. That explains the 8% usage on a 24 thread processor. I guess we're runnig ancient software here.
    Adobe pls fix.

    Same problem here 2022, AMD Ryzen 9 3900X, RTX 3080
    1h of analysing 2 tracking points for 1 minute footage (Position & Rotation)
    23 GB of RAM used, 8% CPU usage, 0% of GPU usage

    Hi Kevin,

    This is also an issue for me. It's terribly slow.

    My question is; why does the After Effects Detailed Face Tracker process so utterly slowly when Character Animator can do this with many more tracking points in real time?

    It would be very advantageous to have an option in After Effects for the same real time tracking capability that Character Animator has, along with the additional tracking points.

    Currently I can't even use the Detailed Face Tracker in After Effects it's that slow.

    Thanks,

    Rowan

      Facetracking doesn't depend on any specific hardware safe the fastest processor you can find. There is nothing wrong. The process as such is simply slow due to the complex analyses.

      It uses only one CPU core  at 100% out of 12 cores, what causes it to not use all cpu cores, may be its with this version of AE cc 2017, I read somewhere that the option was available in earlier versions of AE that could force to use all cores simultaneously.

      15 seconds is an eternity for most visual effects shots. AE is slowing down and running out of resources because the shot is so long. Trim it to just the frames you are going  to use or break it up into 5 second sections and then assemble the data later.

      Most of the people that I know that use AE professionally only work on the frames that are going to be used in the final movie. Most folks just starting out and most amateurs, which is the majority of AE users, spend a huge amount of time working on frames that will never be in the final edit.

      BTW, snap chat is not doing the same kind of processing at all. It's just finding a simple t shape and looking at a couple of areas of contrast. Basically similar results but an entirely different process that is looking at a lot more data. Could AE be more efficient, sure, but you are comparing apples and oranges. the only similarity is that they are both round.


      i am able to trim the clip in 5 seconds and do tracking on individual clips but even than it also require to delete cache and memory after every clip tracking to ease it otherwise system get slower. but i can't figure out how to assemble those individual clips into a single slip with all the tracking data attached.
