rem flash setting
@title flash
@param a off or on
@default a 1
set_prop 16 a

a = 1 -> Flash on. a = 2 -> Flash Off. a = 0 -> Flash Auto.

this script is working on my s3is in non-movie mode. so it *should* work on your digic3 when you replace the 16 with the 143, no?
thats correct, original canon osd still shows flash off, but flash fires
to change back i have to set original flash setting to off

Maybe the behaviour i described above is because of the flash is not full charged

thanks

...This script makes sense only for S series for picture shooting in video mode...

Do you mean: ...because they don't have a dedicated video button ?
Or is there a further difference to the other models, e.g. to the SD series ?

On the newer Ixus models you can attach Rec. movie to the Print button and use it with a long press.

In still record mode then you get the remaining video time OSD and you can record a movie without changing the mode, recording starts directly & after stopping the movie recording you are back...so this seem to bee the same procedure as on the S-series with the dedicated movie button ?

what happens when you press the shutter during such a video recording? i guess the recording stops? on s-series, a picture is taken, and the movie continues... see my video for example

Thats also on ixus70
pressing shutter or let a script call shoot_full stops movie recording

i have edit my post above. after the scipt finished the flash fires itself?!?

Hi all,
first of all I must declare that I don't understand script writing.
As I uderstood the script ewar posted wait 1000 untill fire the fire.
I tested it on my g9 and it does nothing, nor in video mode nor in single shot mode.
I've changed the set_prop to 16, 79, 122, nothing in any case.
What else should I try?

This is the last script I've runned:

rem set flash mode to "off" before shoot
press "shoot_half"
sleep 1000
rem override flash mode to "on"
set_prop 79 1
press "shoot_full"
sleep 1000
release "shoot_full"
end

bye, and thanks to all :)

This script is only for S-series with "picture shooting during video recording" built-in feature.

Sorry for the misunderstanding.
Is there something that can be done to control the flash during a long exposure shot?

awwrite, override of flash during video on s-series (and probably tx-1 as well) is in trunk now.
next project will be the manual firing of flash via script. thanks ewavr!
