Can someone help me fix the script so that it can work?
Which script is that? Link it or attach it.

I see. Apparently this camera unlocks AE when recording starts. What happens if set_aelock(1) is repeated (once) after that...?

Attached script puts a set_aelock(1) after a full press / video button press.

@mojo43 :  please try it and see if that helps ?

None of the scripts work with SX40 HS, even if the maximum ISO is under 1250.... Any possible ways to run it on SX40HS??

Thanks so much, I will try it later today when I get back home. Sorry that I didn't respond earlier. I am not sure why, but I didn't receive a notification that anyone responded to the thread. I will let you know soon!

I tried the script and unfortunately it is still not working. It is like the exposure will change for a brief second and then the autoexposure kicks in. Again the script works perfectly while not recording. I did find something out. The fast EV setting turns off autoexposure while recording video. I manually control the exposure, but at least the exposure is locked... Any other ideas?

Thanks in advance!

The solution isn't a complete fix - if I stop the video recording by pressing 'Set', the start another one (without stopping the script) I get the same crash.
So I need to add the half press stuff inside the is_pressed("set") condition? Or maybe reassert the half press after each time we stop recording?

Making me a little nervous about cameras with video buttons here - I'll go see if "my" sx50 has returned home for its day of birding.

Update :  sx50 is happy with the changes - although it gets "unhappy" if you try to press("video") when the mode dial is not set to video mode.  This works when CHDK is not loaded - I guess for now the warning about not being in video mode applies.

On the G12, releasing AE lock and re-doing the shoot_half between videos stops the crash.
My hacked up version attached.

Next problem - on the G1X the camera crashes when the script ends after the AE unlock :(

Edit: SX40 mostly works (start, stop, adjust exposure); but crashes if ISO set above 1250.

Edit2: After hacking in support for 'press("video")' for the IXUS310, the script works; but has the same problem as the G1X - crashes on exit after releasing the AE lock.

After more testing I found the SX40 also crashed on exit after releasing AE lock.

However I've made some progress on fixing this.

Adding
  call_event_proc("TerminateAdjustmentSystem")
to the restore() function before calling set_aelock(0) stops the G1X and SX40 from crashing (IXUS310 still crashes a lot).

This still works on the G12 (which did not have the exit crash) - interested to see if it has any effect on other cameras.

Updated script (v3.4) attached, this also gets the initial Tv, Av & Sv values at startup and restores them on exit.

Phil.

  sx130is (1.01d & 1.01f)
  ixus310hs (1.00a & 1.01a)
  sx40hs (1.00d, 1.00g & 1.00i)
  g1x (1.00e, 1.00f & 1.00g)
  g5x (1.00c, 1.01a, 1.01b)

Is that just in video mode?  And if so,  in video mode when you have used Tv,Av,Sv overrides?  Or does it crash using AE lock in normal image shooting modes?
