Littleton Sunrise 12/22/15

This is another attempt at a sunrise time lapse.  This was done using 999 frames 3 seconds apart.  For some reason, 999 is the maximum amount of frames my camera will do using the internal settings.  There also appears to be a frame loss towards the beginning of this video and the last one I created.  I’m wondering if it is the camera or the software I’m using.
