Slowly please!
That's
my concretization of the effect I am adressing here.
(I'm no native speaker so my words my not always hit.
And "wobbling" maybe was even wrong, as "wobbling" seems to be the same than "shaking".
I tried to find a better fitting word, it that was (see above) "kneads within".)
This effect occurs - to my observation - allways if you 2D deshake a large fov movie. (I wonder how often I wrote this expression in this thread)

To say it explicitly: That won't be me.
As I don't know enough either.
And the answers (kindly by shekh and wonkey_monkey) gave me ever more questions.

quad is Avisynth I don't know anything about (& different sub forum).
But if it does simply resize lines wrt to a reference line, then it will be correct only for fov = 0.
(No math, but just simple imagination
)
Sorry, but I'm at a loss like you. Can't help any better.
Tried to contribute by describing an effect that possibly could be enhanced.
Ran against walls.
