The video's author described the software and method he used....
Quote:The formation flights and prerecorded flying scenes were created using FSRecorder (freeware). Just so that there is no ambiguity, I flew each of the aircraft... no special programming. All video was shot using Fraps and my head tracking hardware/software
FS-Recorder-freeware-

Fraps-Video capture-freeware/payware-
http://www.fraps.com/-My guess is he uses the payware version as there is no 'Fraps' watermark. The freeware version has a 30 sec. limit for each clip, but you seldom use clips longer than 30 sec.
Basically you create and record flights with formations if you want, as described in the FS-Recorder manual. You then play it back with FS_Recorder, creating the camera angles you want, and record with the Fraps video capture software.
You then stitch the video clips together with video editing software like Windows Movie Maker.
At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation. Igor Sikorsky
