The problem was caused by cropping on an odd-numbered line, they have to be even-numbered to suit the colour-filter array.

Let us try the A1100 colour profile anyway, I will post in a few minutes.

Nothing more that I can do.

I cannot just guess colour matrix values.

If you have access to a 24-colour chart you could use DNG4PS2 to create a matrix.
You can also try photographing the colour chart on a monitor.

It is not easy to do.

The programme often just tells you the errors are too big to proceeed.

Let us see if philmoz can give more information about the digital zoom problem.

Can't find the relevent posts right now - sorry.
Was it this ? :-
http://chdk.setepontos.com/index.php?topic=6560.msg69505;topicseen#msg69505

Might have been related - IIRC it was around the same time period. However, there were explicit postings about zoom in video getting stuck in digital mode and not being able to revert to the mechanical range. Something like this :

If the letters on the carton are white, then the JPG image is slightly blue-green, it needs more red.

You need to include something that is white or neutral grey in the image.

Guess it starts at line 145 here http://trac.assembla.com/chdk/browser/trunk/platform/generic/wrappers.c

Getting a bit complicated to set the zoom.

Actually, I believe that refers to something quite different.

That zoom problem related to setting a zoom position manually from a script and crashing the camera when you tried. It was an interaction of some sort with autofocus. I tracked it here for a while :

http://chdk.setepontos.com/index.php?topic=7071.0

Philmoz solved it for some cameras (his & my G10) but it is still an outstanding issue for the SD780, SD940 and SD980 and possibly others.

The zoom problem in this thread is different - it does not cause a crash. All that happens is that when CHDK enables mechanical zoom in video mode (a feature not available in the default Canon firmware - likely because the zoom noise gets into the audio track) it will zoom in until digital zoom takes over. Once you are in digital zoom range you can't get back to mechanical zoom range unless you stop recording.
