-    -i --file_path          Input file
-    -enc --encoder          Encoder to use (aomenc or rav1e)
-    -e --encoding_params    Encoder settings flags
-    -a --audio_params       FFmpeg audio settings flags
-    -t --workers            Maximum number of workers
-    -tr --threshold         PySceneDetect threshold
+    -i --file_path          Input file (relative or absolute path)
+    -enc --encoder          Encoder to use (aomenc or rav1e. Default: aomenc. Example: -enc rav1e)
+    -e --encoding_params    Encoder settings flags 
+    -a --audio_params       FFmpeg audio settings flags (Default: -c:a copy (copy audio from source to output) )
+    -t --workers            Maximum number of workers (overrides automatically set number of workers. For Aomenc recommended value is YOUR_THREADS - 2 (Single thread per worker). Rav1e can use tiles that uses multiple threads, example:  '--tile-rows 2 --tile-cols 2' load from 2.5 to 3.5 threads, optimal for 6/12 cpu is 4 workers)
+    -tr --threshold         PySceneDetect threshold (Optimal values in range 15 - 50. Bigger value = less sensitive )
