Slow work of After Effect Tracking motion

Hi All,

I would like to check if this is happening to me only or this is the product work in general.

I have After Effect 15.1.1 version and PC Win 10 / 32Gb RAM/ Samsung 960 M.2 SSD / i7-7820X / GTX 1070 8Gb.

When I'm doing a tracking of a small area and tracking of a slow movement it takes more than a minute to move from frame to frame. I do not see any CPU usage or memory usage while tracking, looks like it does nothing all the time and only the last second create a point and move to another frame.

Maybe I have some misconfiguration, however, I did not found anything or any kind of settings related to a tracking mode specifically.

Note: I did try it on the 4k video, Full HD video and even on 720p video, the result is exactly the same. Each frame tracking done in between 60 to 80 seconds.

Do you have any suggestions about it?

Thanks

Hi. I have similar issue in cc2020, 17.0.5 build 16, but reducing the tracker search area only improve speed a little. I' ve tried to reset prefs but didn't help. I'm lost with this, because in an older machine with cc2018 tracking motion is really faster. Please a need some help. Could it be related to the graphics card drivers, or maybe to any plugin i have installed? My nvidia drivers are up to date, is there maybe any concrete version of the driver working better?

Im also having an extremely hard time here, I'm 2 hours 22minutes in on a 0:05:00 second clip where all I'm doing is tracking a face and I've currently only tracked 0:01:06 getting pretty annoyed

I'm so glad this has helped all of you, it took me several days and effort to find out this silly thing breaking my brains with AE.

Cheers!

I had a similar issue.

I was able to resolve this by choosing a much smaller area to track. I initially thought I'd chosen a pretty small area to track, but once I halved the size, everything processed way faster.

2 suggestions.

re-set preferences... On Mac hold down cmnd/option/shift while the app is opening orr on Windows hold down cintros/alt/shift while the app is opening.

Also try going to Edit/Preferences/ Media and Disk Cache (on Windows) or After Effects/Preferences/Media and Disk Cache (On Mac)

And use the options to clean the cache.

I hope that this helps.

Thanks for a fast reply, I have done all the steps you said and now it takes about 15-20 sec per frame. I believe this is the maximum I can get from this software.

The speed of the tracker depends entirely on how big the feature area and search area are. The codec of the original footage can also influence the time it takes to analyze a frame. MP4 compressed movies are interframe compressed so the CPU has to figure out where the pixels go in the in-between frames and create them before they can be tracked. Visually lossless formats don't have that issue. Every frame contains all the data in a frame, so every operation in AE that is looking at the pixels in the frame will be faster when you use formats that are not using GOP compression (Group of pictures). All MPEG compression uses some kind of GOP compression and it not very suitable for production.
