How do you blur part of a video

[Master Tape]

I want to blur out part of a video, to censor something. I'm keen to see how BlurBox looks, but i can't get it working.

FFmpeg command to create a blurred box in a video:

ffmpeg -i input_video.mp4 -filter:v "drawbox=x=100:y=200:w=300:h=200:color=black@0.5:t=fill,boxblur=luma_radius=10:chroma_radius=10" output_video.mp4

parameters:
- `x=100`: X-coordinate of the top-left corner of the blur box
- `y=200`: Y-coordinate of the top-left corner of the blur box
- `w=300`: Width of the blur box
- `h=200`: Height of the blur box
- `boxblur=luma_radius=10`: Intensity of the blur effect
