hello, when i put my clip (recorded from obs) in blur, I have this message :

Script evaluation failed:

Traceback (most recent call last):
File "src\cython\vapoursynth.pyx", line 2239, in vapoursynth.vpy_evaluateScript
File "encodings\utf_8_sig.py", line 23, in decode
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 187: invalid start byte

If someone can help me, would be great :p
