Repeating “Out of memory” + 3D Camera Tracker errors on two different workstations (AE 2025, Win 11

Explorer ,
Oct 10, 2025 Oct 10, 2025

Hi all,

I’m getting repeatable memory errors in After Effects on two different PCs with the same project (a light 1080p comp). It happens during RAM preview and when running the 3D Camera Tracker.

Error dialogs (screenshots attached):

  • “After Effects: 21,820 MB / 132,563 MB of memory could not be allocated … (12803 / Unidentified caller)”

  • “After Effects: Out of memory (23::40)

  • “Not enough memory for 3D Camera Tracker at frame 0 (25::16)”

  • On one machine we also saw: HuionTabletCore.exe – 0xc0000142 (tablet not connected; driver removed)

  • Once Windows even refused to open taskmgr.exe: “Not enough system resources to complete the requested service.”

Project context

  • 1080p, standard effects, not GPU-heavy.

  • Errors feel random: sometimes at preview start, sometimes during camera-track analysis.

What I’ve tried

  • Purged All Memory & Disk Cache; Disk Cache on local NVMe (hundreds of GB free).

  • Increased Windows pagefile size (also tried “system managed”) → no change.

  • Latest NVIDIA Game Ready driver tested on the RTX 3090.

  • Huion tablet driver fully uninstalled; VC++ 2015–2022 runtimes present.


System A (the intern’s box)

  • CPU: AMD Ryzen Threadripper 3960X

  • RAM: 128 GB DDR4

  • GPU: NVIDIA RTX 3090 (24 GB)

  • Drives: 2× NVMe Seagate FireCuda 520 (500 GB)

  • OS: Windows 11 Pro x64 Build 26100.2605 (24H2)

  • AE: Creative Cloud, current (Oct 2025)

System B (second workstation where the same project fails)

  • CPU: AMD Ryzen Threadripper PRO 5965WX (24c/48t)

  • Board: ASUS Pro WS WRX80E-SAGE SE WIFI II, BIOS 1602 (2024-09-04)

  • RAM: 128 GB DDR4-3200 RDIMM ECC, 8-channel

  • GPU: NVIDIA RTX 4080 Super (16 GB)

  • Drives: Samsung 980 PRO 1TB + WD Blue SN570 2TB (NVMe)

  • OS: Windows 11 Pro x64 Build 26100.6725 (24H2)

  • AE: Creative Cloud, current (Oct 2025)

    Any help?
