I did not deep-dive into all the functionality yet, but for the main task I was looking for (converting Youtube video with high-quality at speed/scale), it's doing well :)

Way faster to proceed than those free online converters.
And it's good that it works with 4K videos (and above).

Definitely gonna help to streamline my process as I'm a short-form video editor and usually need to grab such source files.

Thank you!
