Should I also have changed other things?
Found some time for lines to make it more stable:
-- exit_alt button proof; Leave <alt> for zooming, <rec> or not.
Code: [Select]
       repeat sleep(100) until get_alt_mode()
               wait_click(200)-- Preset minTv that´s save for Your cam. (Start recording only): Bright preview, std video.
-- Within limits still to explore script works fine, ends smooth.  :xmas
Crashing: Try to shoot in exit_alt...
Code: [Select]

So far, the S3IS works well. It's older, and yet it outperforms the newer SX40HS

Sx270:
FHD with upto ... 0.8 sec. BUT after finishing script a reboot is necessary.
(Even if nothing was done... Edit: No matter, 1/2way gone by cam...)  :haha
Need to start with lens open.
Seems an issue with AEL (@ lowlight & ??).
Crashes happen between help screen and 1st drawing draw_box()...
    or after script finished.... 1st AEL action --> Cam off.
Manually swapping to <play> [review video|menu action|...] <rec> same.

Edit2: Sx270 works even with ISO 6400 12800, so Sv tables grew...
++ Zoomkeys can be used to adjust ISO for easy dimming...  ::)
(... then exit alt to zoom...)

Sx270... seperate Digic 6 version, works very nice in VGA, HD + FHD.
Set menu, then reboot, so settings are valid after crash.

Seems fine so far with Tv>=1/30 and valid ISO on other cams too.

SX240: ISO>3600 crashing ...
D20 could have 6400.
