So I tried something super new... I went through my video footage and exported frames. However, we shot everything in vertical. As a test, I skimmed through a video pan of the audience and exported the frames that I felt would be best for a pano. Brought those frames into photoshop to auto-align for a panorama with 4 vertical frames. I'm genuinely impressed with how easy it was for it to turn out as well as it did. I also took a frame from the firework finale and masked it into the bg.
