Works for 5sec 540p on 256GB RAM. Going any higher on res or length and it seems to blow up consistently:

[Python Error] /Users/os/.local/share/uv/python/cpython-3.13.12-macos-aarch64-none/lib/python3.13/multiprocessing/resource_tracker.py:400: UserWarning: resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown: {'/mp-fjl0z2pk'}
  warnings.warn(

The app shuts down then restarts saying "API key required"

Make sure you select full local model execution in the settings - some features might try to call default APIs

Please make sure to include full crash logs in reports. The single line won't help alone.
