chdk + time-lapse scripts

Hi guys,

I'm starting to think this is not possible, at least not with the G9, so I thought I'd check. I'm trying to get time-lapse shooting working with an interval of 1-2 seconds, but even when set to 1 second, it takes about 4 seconds between shots.

Are any of you able to get it down to 1 or even 2 seconds? If so, which script are you using and which camera are you using?

Thanks

What script are you using? Are you shooting jpeg or raw?

Canon specs say G9 is capable of 1.5 FPS in continuous mode (large/fine jpeg, raw presumably slower) https://www.usa.canon.com/internet/portal/us/home/support/details/cameras/support-point-and-shoot/powershot-g-series/powershot-g9

You will generally not get a faster rate than the Canon spec. If you use an intervalometer script that does a full half press, auto focus + auto exposure, shoot cycle for every shot, it will be much slower.

If you use a script that shoots in continuous mode or holds half press clicks full it will be faster. https://chdk.fandom.com/wiki/Lua/Scripts:_Raw_Meter_Intervalometer is a script I wrote using this technique, which can generally shoot at speeds closer to the canon continuous mode spec.
