Time Lapse Video

Sunrise in Destin, Florida (MOV format)

This 26 second time lapse sequence was shot during a one hour period using the G12 triggered by an intervalometer.  The G12 was set at manual focus and manual exposure of ISO 80, f4, 1/200 second shooting JPEG at 1920x1080 resolution.  The exposure was my guess (based on “open shade”) for the end of the sequence, 6:36 am.  The intervalometer was set for 6 second intervals between shots.  The G12 and intervalometer were each battery powered and 599 shots were taken.  Those 599 shots were imported into QuickTime Pro as a sequence and output as the above .mov file.  I’m pretty happy with it.

I’m relatively new to video and don’t understand much of what I’m doing (or trying to do).  In fact, part of the reason for this post is to compare videos after going through processing, uploading, posting to the blog, etc.  Whereas the opening video (above) is a large .mov file that was uploaded to YouTube (took a while), the video below is an .avi version converted from .mov in Adobe Premiere Elements; it is only 69 MB but YouTube does not pick up that it is HD video. 

AVI format

Next I loaded the .mov file into QuickTime and exported it as a 4MB .mv4 file, see below.    Again, not HD.

MV4 format

I’m very curious how these will compare after going through the process and also how I can improve the process.

Thanks for the info on the intervalometer. There was a CHDK script I could run for this functionality on my G9 before it bricked. Not available for my G10 or the G1 X as yet. Looks like I'm buying one.
