filmmaker cy kuckenbaker describes his method in more detail:
"I locked the camera (canon 7D with a EF-S 17-55 f/2.8) on a tripod and shot the planes with 1080p video at 24fps with an exposure Id tested the day before (50/s, f/13, ISO 100) that would keep the sky deep blue with no blowout for a good chroma key. To give the video a sense of temporal change as the planes fly by I did an 8 hour time-lapse under a bridge nearby shot at the same angle and composited it over the planes. without it theres no sense of time passing. I used an intervalometer to shoot about 800 images with the same exposure as the video. Once I had it posted as a regular video clip, I keyed the sky out of it as well. I put everything together in adobe premiere, which challenged my system since I needed 40 video tracks to stack all the airplane clips together. The last piece was to put a new sky back in a still image with depth and clouds thats panned using key frames in premiere."
