Thanks again Sean, The methods you suggest are logical. That's pretty much how I attack problems anyway. I was hoping there was a direct command to transform the projection of an image. That would be a lot simpler (and probably faster as far as CPU cycles go) than using the entire Hugin program.
I will try making a .pto and inspect it. It might give me some clues. I also want to mention that I found a way to do what I want in Photoshop CS6 but its also a bit inefficient. I could not find a way to do the equirectangular panini directly in PS so I used several filters to achieve a similar result. Since the images are all the same size and shape (they're all video frames) my sequence of adjustments can be repeated across all of them. - I open the video file in PS and make it a "smart layer" - I apply my sequence of filters to it (they are not applied immediately) - I select "render video" and choose my video output options - Then I wait just over 2 hours for PS to process 2 minutes of footage (7200 frames) but then I have a complete .mov file. So, the drawbacks of using PS are 1) its close but not exactly what I want, while Hugin does exactly what I want in a single step, and 2) it takes forever and I have a fairly fast Mac. I haven't timed how long it will take to export a video to 7200 separate images from Premiere but that will play a factor. I've also wondered how hard it is to make a plugin for Premiere. With all of the thousands of things you can do in Premiere (or After Effects) I was surprised I couldn't find a plugin that would let me change the projection of a video. Maybe there is but I wasn't able to find it after 2 solid days of searching. I'll post what I find as I experiment with the .pto file in case it can help others in the future.
