Hot launches can certainly look like that too, because you have the rapid ejection of the exhaust gas inside the tube (via the side pipes) pushing up against the missile's own exhaust as it launches, so the two gases are effectively counteracting each other, creating a kind of pressurised vacuum in between that's devoid of smoke, if only for a split second which in this instance the camera was able to capture for you to see.
Pressurized vacuum?

It's like a vacuum that's created by highly pressurised gases from opposing sides, similar to an implosion-type detonation where the rapid pressurisation of where the two gases meet (as well as the air caught in-between) expand outwards like a shockwave from an explosive reaction. So you end up with a small vacuum in the middle for a brief moment with no smoke as air gets pushed out instead of getting sucked in as would be the case with a normal vacuum.
There's probably a more proper term for it which escapes me. I'm pretty sure "reverse vacuum" ain't it, however.
