What is the slowest shutter speed available then? Is it 1/x sec. for x fps movies?

Original firmware in A710 sets maximal exposure time in video 1/30s (PROPCASE_TV  = 480) for 30 and 15 fps, 1/60s (PROPCASE_TV  = 577) for 60 fps. But we can set 1s (1 fps) or more...  (not in this release).

I have the SX100 IS and when not in CHDK mode I like the movie mode exposure lock, enabled with the Up arrow. I can enable this even in CHDK mode, but when I half press the shutter key for the AF feature (that's excellent) the exposure lock goes out and the rest of the clip the exposure becomes in continuous adjusting.  Does the script have some code for make also a exposure unlock? And, in the case of exposure Lock, is it possible to make some adjust to the exposure when zoom in or zoom out, in order to compensate the lost or gain of luminance when the zoom is applied.

Well, experimental build (Allbest based) for most A-series cameras with Ev correction in video here (with src.)
When video is recorded, press "+/-" ("disp" for cameras without "+/-") key. Exposure is locked and you can use <- and -> keys to adjust it (0.5 Ev step, Ev display present on screen). Press "+/-" again to exit this mode; after optical zooming or refocusing this mode disables automatically.
Unfortunately, positive Ev correction is available only in bright environment (in this version CHDK can change only exposure time, not aperture or ISO).

Thanks Ewavr for adding the movie mode exposure lock, I use this function all the time on my A640.

Does the current version of CHDK allow the control of Aperture and ISO in Movie mode yet?
I'd love to be able to lock in the ISO at 80, shutter at 1/30th and adjust the aperture on the fly according to the brightness of the environment.

is there a way to make this exposure lock work on the S95 ?

edit: solved - if you preselect the exposure via EV, it is locked.
