Something was clearly amiss with Marvel Studios' new Avengers: Age of Ultron YouTube trailer, almost to the point of being unwatchable. It seems there was a bizarre stabilization filter on that's warping every frame — and causing the black bars to bounce around like crazy throughout the clip. (Update: It's fixed now, thankfully — all verb tenses updated from present to past.)

Here's Iron Man, for example:

It wasn't intentional (although it does make for some trippy art). Marvel is aware, however, and is working to fix it (Update: it's fixed — see above.) This is Executive Editorial Director of Digital Media Ryan Penagos (aka "Agent M"):

Our best guess is that someone checked off YouTube's own stabilization tool, which is how Marvel was able to fix without uploading. The lesson? If you're going to hold Twitter hostage, be sure to QA the unlisted YouTube preview early and often.
