Yea I couldn't get the recordable window to work, it was just black in OBS sadly.
The reason I ask for video processing is that it can run in the background when doing other stuff on the pc or when away from the PC, without having to use up a monitor in the process etc. 

Or even if it had to be a totally separate program, I would happily pay like £50 for a video processing tool that could censor input videos just like this live tool does and then save them out as a new file. I have been looking for a tool that can detect and censor videos for years with no luck, it's either the whole video gets censored or it's only a live/browser censor. 

How difficult would it be to add in a feature where you could feed the program say video.mp4, and have it censor it frame by frame, then pump out a video_censored.mp4 version? You already have ffmpeg as part of the program so I assume splitting audio, censoring and recombining could all be handled with that. At the moment I do something similar with ffmpeg but it applies one kind of blurring, to the whole video rather than specific filters to detected parts.

No he's correct, if you don't chase up trademark disputes you can lose your trademarks. Nintendo had this exact thing happen with a donkey kong trademark back in the 90s, it's why they are so aggressive about taking down anything that even remotely targets their IPs nowadays.
