Inconsistencies/"Yellow" Trailer

"Yellow" Trailer
Up until the close shot of Yang and Junior "kissing" they all have fireaxes then, as it cuts to a wide shot, they seem to be holding swords (same seen in ep1), and back in the close up they have axes again. The wide shot could have possibly been done later when the models had been updated while everything else in the trailer was with an older model.

 * 1) RWBY Yellow Trailertion - At around 2:21, a man can be seen running in one spot for less than 1 second before it cuts to Junior.
