Great start Luc, I've subscribed to your channel.
One thing I noticed, especially with the second video, is that trying to convey something via video forces me to clear up my thoughts even more to break in down. In writing, I can get away with intellectualizing, but this won't work on YouTube, so rhat might be a good thing.
It's interesting how this works indeed, and I am assuming you are using this format as a way to engage with younger audience members, ones who don't read? ( which is a lot these days) which I think is a great idea.
I found the videos to be clear and concise as far as the idea and audio goes, but I would agree that the jump cuts (technical term for when the cuts cut to a similar shot size and framing) is quite distracting. If you want to cut a lot, to keep the pacing up I would recommend cutting from a wider shot to closer or vice versa, that way it's not a s jarring. Also with the jump cuts, if you're using adobe Premier to cut, you can use a in the effect - video transitions - morphcut, which does a good job of getting rid of the jump cuts.
Overall, I think the lighting and framing is good, just the above mentioned jump cuts, another thing you could do, is have less of you talking and more cutting to stock footage as that won't seem as jarring.
As an video editor myself I can appreciate the time and effort that has gone into this!
Any way just my 2 cents, I look forward to seeing more
