Some on you have been having trouble following my ill written instructions on doing this, I'm not the best at writing tutorials it seem :P
The article is available here: http://cpdigitaldarkroom.com/2013/07/how-to-post-custom-video-to-instagram/
I decided to record it without me explaining it step by step so I could get it up faster. Watch it in fullscreen and you'll be able to follow along on Mac. Windows should be relatively the same.
If you need any more help don't hesitate to contact me! I'll help you get your video posted.
