python script: https://github.com/amdonatusprince/youtube-channel-video-url-extractor/blob/master/main.py

in cmd or powershell (in the directory where script it) run: python <<script>>.py.. change the channel url and target directory at top of script. (may need python on win 10), if so allow it to be installed.

may need selenium (pip3 install selenium) see here: https://bobbyhadz.com/blog/python-no-module-named-selenium

may need bs4 module (beautiful soup). : pip install beautifulsoup4

I sincerely hope this works for you – it didn’t work for me!
