I think 2Conv https://2conv.com/en63/ and Joyoshare Screen Recorder https://www.joyoshare.com/screen-recorder-for-win/ work perfectly as well. 2Conv is my favorite free online tool to download YouTube videos to MP3, MP4, and AVI. The Joyoshare program supports more formats and has more flexible features. I always use it to save online movies and record gameplay in 1080p without latency and time limitations. I like both of them.
