I do make basic videos of me playing music. It could be good for mixing in backing tracks. The Linux tools are generally pretty good and it's easier to use these days.
I consider Audacity to be mainly an audio editor with some recording capability. Ardour is a full multitrack system with real time effects. It can do far more than I need really, but as it's free to use I get the benefits. I do actually pay them something anyway. I wish some open source projects were on Hive so I could support them with votes.
Have fun with your videos.
