After two weeks I'd be a lot more shocked if you were bowing straight.  Luckily, you have a video cameral.  That's not as good as a violin teacher, probably, but at least you can see what you're doing and you'll be able to fix it.  

Clearly, the issue here (as seems to be for 95% of new violinists) is that the motion for moving the bow is coming from the upper arm at the shoulder, rather than the forearm at the elbow.  It is impossible to bow straight by bending the arm at the shoulder.  Instead, all but for roughly the lowest 1/4 - 1/3 of the bow, the proper motion is created by extending and collapsing the arm at the elbow. Shoulder movement is mostly confined to raising and lowering the angle of the bow to make contact with the desired string. 

The left hand and arm are only responsible for playing the correct notes and vibrating.  The volume, tone and the soul of the violin is all in the right arm.  Fiddlerman has some videos on bowing that are well worth watching.  In addition, the great violin teacher Ivan Galamian has much to say on the subject.  Here's an entire work by Galamian, but the link points to the beginning of the bowing section.  It's well worth studying.
