+### Crop & Trim

+These CPU-intensive features are enabled by default so be sure to disable them on resource-limited systems. 
+
+Additionally, the source materials they use for detection relies on the NHK World stream being in 1080p. **Using a lower resolution stream URL will result in crashes upon detection if trim or crop is enabled.**
