OK seen the video your referring to, which was made by the creator BILL / William over at Lionheart Creations , payware aircraft.
a lotta of the views your seeing are done, using the Keyboard commands on your computer keyboard,,, some, not all.
other views are used like Track IR, a head tracking software device
Bills video was uploaded in 2010, not to long after TRACK IR came out.
You can also use the space bar and your mouse to move around Zoom In & Out too , in "FSX"
The keyboard commands to tinker with are :
CRTL Shift Enter
CRTL Shift Backspace
Enter Shift
Enter Backspace
CRTL - + Keys
and at the same time hold down on these
CRTL CRTL SHIFT ENTER
CRTL SHIFT BACKSPACE
Try those and move around your cockpit or aircraft
I set up ALL my Aircraft CFG Files so that the views allow me to move around any direction
XYZ = TRUE in the Aircrafts Views section !!! { -------- very important if ya want to move around the Aircraft !
Track IR5 :
http://www.naturalpoint.com/trackir/products/trackir5/ Heres one of my YOU TUBE Video I made some time ago, using the DASH 7, by Milton Schupe , I used a combination of keyboard commands and my Track IR5 to move around the cockpit and outside the aircraft - recorded with a registered version of FRAPS recording software
then I took all the Video clips and put them into my Serif Video Editor and edited out badd unwanted footage , no special effects used.
Then process the video, so it can be uploaded to YOU TUBE, and they'll process it again on the end.
