I have gotten ultravalometer and motion detection to run seperately on sx10 is. I would like to combine these two in order to make time lapse of say a storm but still not miss any lightning strikes. Is this possible? Have searched to he best of my ability but this is a broad site.. thnks

You can only run one script at a time. You could write a script which did both motion detection and interval shooting, but I'm not aware of one already written.

Don't forget what the H stands for.

Build yourself a lightning strike detector and use the script to control your camera:

If you want directivity you can modify a motion detector:

Google for terms, lightning photography and lightning photography trigger, you will find a number of guides including commercial lightening detectors and some archived CHDK guides posted from other sources than the CHDK forum:

Some examples:

It looks like you may fin it here:
http://chdk.wikia.com/wiki/UBASIC/Scripts:_Multipurpose_Motion_Detection

you may need some modifications so that when the motion detection function exits on timeout you take a shot anyway before rearming it?
=> Changing the following line:

Code: [Select]

if a=1 and t>0 then shoot

to

Code: [Select]

if a=1 then shoot

Note: Your JPG to movie converter should be smart enough to use the time stamp within the JPG file to properly rebuild the timing for your MJPEG movie.
