Then what is the video mode that you mention and in which selection does it works?
In CHDK context, "movie mode support" means a certain set of extra features associated with video recordings.
On this camera, these features are:
- Ability to modify the video stream's bitrate. Constant and variable bitrate modes (CBR, VBR) are available, you can select one of these in "video parameters" -> "video mode". In CBR mode, "video parameters" -> "video bitrate" can be used to select the constant bitrate (it ranges from 1/4 of factory bitrate to 3x factory bitrate). In VBR modes, "video parameters" -> "video bitrate" specifies the maximum bitrate that will be used, and "vbr minimum bitrate" specifies how many percent of the maximum bitrate will be the minimum bitrate. Video bitrate will not exceed 41000 kbit/s, regardless of the selected multiplier ("video parameters" -> "video bitrate").
- Time based video restrictions are lifted. The new time limit is 3 hours for a single recording. I did not actually test this, but I believe it should work.
File size based restrictions are unchanged. If video files are limited to 4 GB (the manual says so, I think), recording will stop when that amount is reached.

It does not matter which camera mode is used when recording videos, the overrides should be effective.

Ok, thank you, this is clear now. I can confirm that I can setup these things with 110f. I am not sure about the 3 hours video (I haven't tried such long time) but the other settings are working.

It's possible to make the camera switch on by itself using a firmware function (discovered by Ant). A Lua function enabling the use of this feature is posted here. It can be added to time lapse scripts to conserve power when the camera is not shooting for a longer period. It can, in some cases, make an external control device (microcontroller, computer) unnecessary.

To shoot long time exposure I am using something like (from Python):
Code: [Select]
camera.lua_execute('set_tv96_direct(usec_to_tv96('+shutter_time+'))\n' \
                                      'press("shoot_half")\n' \
                                      'repeat\n' \
                                      '   sleep(10)\n' \
                                      'until get_shooting()\n' \
                                      'press("shoot_full")\n' \
                                      'return')

This works perfectly and it captures a picture with the shutter_time exposure. Now the question: if I set a long shutter_time (like 300 seconds) and I decide to stop the acquisition in the middle, is there a lua function that I can invoke to abort the current shooting?

There is no such function. We don't know any working method that could be used to interrupt an ongoing exposure.
Bulb exposure seems to be the closest to what you want, but unfortunately, the M10 does not support that (firmware limitation). The EOS M3 does.
