Playback freeze in after effect, I tried everything...
I’m experiencing a recurring issue with After Effects (v24.5 / 2025) on a brand new machine built for motion design and 3D. AE consistently freezes during preview after a few minutes — the interface remains responsive, but the preview image stays locked. No crash, no error message, no way to report the bug.
🖥️️ My setup:
GPU: NVIDIA RTX 5070 Ti (Studio Driver)
Power: 330W adapter
RAM: [insert amount, e.g. 32 GB DDR5]
OS: Windows 11 Pro
AE Version: 24.5 (2025 release)
🧪 What I’ve already tried:
Mercury GPU AND Mercury Software Only rendering modes (same result)
Different AE versions, projects, and compositions
No third-party plugins
Clean cache & preferences reset
Updated NVIDIA drivers (Studio and Game Ready)
Disabled all sync services, antivirus, background apps
Observations:
Preview freezes after several minutes regardless of project size
RAM usage stays stable / doesn’t max out
No GPU or CPU spikes before freeze
AE doesn’t detect this as a crash or bug, so no report is generated
Recap: What We’ve Eliminated
| AE version | 2024 & 2025 freeze |
| GPU acceleration | Disabled → still freezes |
| RAM | Not maxed out (17/83 GB used) |
| Projects | Happens across all |
| Plugins | No third-party |
| Drivers | All up-to-date |
| Reinstall AE | Tried |
| Preferences reset | Done |
| Power supply | 330W (confirmed okay) |
