This sequence was shoot with a 7D to RAW .CR2 files.
10s exposure every 15s.
28mm lens at F2.0.
The CR2 files were batch converted to CineForm RAW (as fast as the CompactFlash would read.) I did a direct conversion form the flash media to local drive with this shell command.
DPX2CF J:\DCIM\100EOS7D\*.CR2 e:\stars1.avi -q4
The results are a real-time playable AVI with resolution 5184 x 3456. This was loaded into CineForm FirstLight for color correction and keyframed image cropping. This was then loaded into VirtualDub for scaling to 1920x1080. I use CS5 Adobe Media Encode to produce the 1080p mp4 upload.
