Comet Lovejoy C/2013 R1 1/4/2014 85mm 30fps 1080p HD Time-lapse Video
This video converts 762 individual photos shot at 85mm focal length into 1080p HD video at 30 frames per second. Each photo was cropped to approximately 3840 pixels on the longest side ("4K video"), then they were converted to HD video at 1920 x 1080 resolution (1/4 the original resolution).
This was shot before dawn on January 4, 2014 on a standard tripod (no tracking mount). Most of the streaks passing through the frame occupy several photos (which have an average exposure time of 2.5 seconds each), so most appear to be satellites. It was shot less than 24 hours after the peak of the Quadrantid meteor shower though, and Comet Lovejoy isn't all that far in the sky from the radiant point of that shower, so if I hunt through all of the 762 photos I might find a Quadrantid meteor or two.
