Just a suggestion .. you should not do it anymore as i can see the flexing of the braze on against the seat tube ... you may accidentally damage the mounting of the braze on without knowing .. just my 2 cents.
This is what I mean, that flex exactly at the tube

I think what you trying to say is you suspect the seat tube is flexing too much or maybe the braze on bracket is not fasten tight enough to the seat tube. Maybe you get your LBS to take a closer look.

I have a bunch of bikes sitting around and I cannot get flex like that. Perhaps that's because they have clamp-on FD's or adapters.
So in answer to the question, perhaps it's normal for a frame with a flimsy braze-on.

There's sometimes a buggy.
How many drivers does a buggy have?
One.
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.

Yes, my Colnagos have steel Brazeons and they don't flex at all. A lot depends on the layup of the carbon around the brazeon, or in a lot of cases, the bolt-on. Flatter frame tube profiles in that area will likely flex more. I was only trying to concentrate looking at the flex right at the Brazeon and the frame in your video and not the flex from you pulling and pushing it at the tail end of the derailleur. Whatever it is, not really much you can do about it except on the newer front derailleurs there's a support screw or "arm" (S2 Campy 2015 and onward) that lays against the frame for added support.
