is it possible to activate long shutter 1/6 or less with less FPS on
the ML?
for example, camcorder canon HV30, has a slower shutter speed up to
1/6 at 6 frames per second in video mode


it would be fairy video effect of smeared image, just like in those
frames:

You can get this effect with FrameMerger (a VirtualDub plugin).

Here's a version modified by me, where you can enter arbitrary
strength values. The zip contains both source and executable.

result of adequate, thank you... lack of virtualdub is that the program cannot not open mov files from 550d, need recoding, but mjpeg from pentax is okay

To open Canon MOV files in VirtualDub, first save them as AVI with
Avidemux (don't recompress them, just change the container).

Two more options:
- Use AviSynth to handle loading of non-avi/vfw codec enabled files. You
can't save in h264 this way though.
- Use ffdshow, it has a vfw version too. (I usually install CCCP:
http://www.cccp-project.net/ it has everything one needs).
