Hi,

The script below will record a series of video clips (.MOV) and then change each clip name to the day and time when the clip started - e.g. 26152534.MOV (15:25:34 on the 26th). The only variable is 's' which is the individual clip length in seconds.

I wrote it to record solar events so I have my camera time set to UTC time (GMT without daylight saving). This means I can accurately time any flares that I capture in astro time.

I run it on my camera attached to a remotely controlled telescope that I control from inside my garage. The camera is controlled from inside CHDKPTP which allows me to focus remotely on the LiveView screen.

One question for the gurus: I can start the script remotely by typing

luar s=10; loadfile('A/CHDK/SCRIPTS/SUNVIDZ.LUA')()

into the Execute text box. Any idea how I can stop it remotely so I can change the telescope target?

	dir = os.listdir("A/DCIM/" .. get_current_folder(), false)

	file_name_new = "A/DCIM/" .. get_current_folder() .. "/" .. new_name .. ".MOV"
	os.rename(file_name_old, file_name_new)
end

	press("video")
