Sounds like video line inspection isn't going to help me very much. The
blockage probably has an inch of other debris sitting on top of it, so the
video wouldn't show us anything. The vent pipe is only about an inch and
half in diameter, so it's unlikely that it is a lost squirell blocking the
vent. Probably just a bunch of leaves and shingle gravel that has built up
into a solid mud.
If they have a tricked-out camera, they might be able to manuever it in
from below. Then again, such a camera service might cost you more. I
wonder if your kids or the kids of a previous owner might have gotten
on the roof and jammed a ball/rock/toy down the vent. Maybe some
varmint/bird decided to stash some object that smelled like food down
your vent for safe keeping.
Have you tried a shop vac? I'm thinking a little upward force might
help. If it's something like a rock or toy, the previous ramming might
have wedged it in too hard for a vacuum to shift things. :(
One other thing: You mentioned you used a hose "balloon". While I
like those and they typically work well, they expand and would keep any
debris trapped if the clog doesn' t dislodge.
To get the surface junk out, put a regular garden hose down the pipe
until it stops and then turn on the hose full blast and wait as junk
flows out the top with the water flow. Even if it doesn't dislodge or
erode away the entire blockage, it'll help a camera see what the
underlying problem is.
BTW, it doesn't hurt to put a small nozzle at the end when doing this
for greater erosive effect.

They make nozzles for garden hoses that are designed to maximize the
force of the stream. Brass, cost about 2 dollars.
Another idea would be to drill a half inch hole below the clog and
push a 3/8" rod up the push the clog up. Don't know about tile
pipes, if one could do this.
If you can get close enough to the clog, you can use a spade bit from
the bottom, or conceivable from the side.

A GOOD shop vac might pull it out. If you can't get the hose in, tape
it to a piece of pvc that will fit into the vent pipe. I wouldn't take
a chance on losing the wand.
