It is not a meteor.I am not convinced it is anything in orbit.I would need to see you record another satellite (doesn't need to transit anything) passing with the camera, scope and framerate and and appear similar.Satellites are numerous and predictable enough for you to catch one for a moment in the sky somewhere....
Freezing the frame, and taking it's narrowest width, making clones and stretching them across the disk of Jupiter (32 arc seconds) it would take about 30 of them. A usual LEO satellite angular diameter is safely 1 arc second across/2 at best if not the ISS, Tiangong, Lacrosse 5. So it just might fit.No cubesat would be 1 arcsecond across.Would need to be a decent sized satellite brighter than Jupiter.....

In many of my Lunar/solar videos I catch small stuff like that all terrestrial in nature...

 Five elsets with epoch both sides of the observation time AND one 35 days
old agree within 1' or better, and 1/4 s according to HeavenSat. But it
shows their track 45' left of Jupiter, and with an angular speed of 0.26
d/s !

Moving your location ~25 km ESE (to +45.60 -73.50) puts the track over
Jupiter.
