#Instructions:

#Create 3 .txt files with the following names in the same folder where you set the log path to: vt_playlists.txt video_urls.txt vt_urls.txt
#You'll use those to store the actual channel URLS (one per line)
#Channel URLS should be in the format https://www.youtube.com/playlist?list=UUP8TJll-FkcJ0CtvWHN7xVw where everything after /playlist?list=UU is the channel ID
#Channel ID is the string following /channel/UC in the channel homepage URL and can be obtained with the following javascript injection: window.location=ytInitialData.metadata.channelMetadataRenderer.channelUrl

#Set the following 3 paths as appropriate as well as add/remove filter keywords on line 22! AND DONT FORGET THE TRAILING SLASHES FOR THE FIRST TWO PATHS (not the executable though)
