Wow, great for timelapses. Can the frame be dumped from a long accumulation (longer exposure) via shutter overide or is that fixed elsewhere? Can speed ramping occur?

        #ifdef CONFIG_500D
        skip_top    = 24;
        skip_left   = zoom ? 64 : 74;
        #endif

Hi Greg ! Do your latest modifications works ? No more greenish color with zoom and full height frame ?  ???
If you think it's impossible, you have lost beforehand

Wonderful, Greg ! Compliments !
Now Wolf should correct his 550D code by following your example, and refresh his pull request ! Great !

@Greg -> awesome :-)

How did you find the right zoom skip?
When I take a zoom silent pic I get no borders, but it doesn't work with 0 zoom.

Hi, again.

Do you think that 1280 x 400 24fps continious raw  is possible for 550d?

Try this:
        #ifdef CONFIG_550D
        skip_top    = 26;
        skip_left   = zoom ? 0 : 152;
        skip_right  = zoom ? 0 : 2;
        #endif

Still pink.
I tried

skip_right  = zoom ? 0 : 1; 

Still pink also.

This value must be 2, this is the full frame. (1734 x 1156)
Check for 5x and 10x. For 500D 10x gives bad results.

On 10x same pink.
I don't mind, still satisfied with the no-zoom DNG :-)

this is your problem, needs to be 2048 or something close to that

dcraw.exe -k 2048 is what you need

autodetect_black_level() produces a value of 0/0 here. Hard code it to some reasonable value, like 2048.

If you have the black borders defined properly, the black level will be autodetected. If not, just hardcode something.

On 600D when I turned debug on it would either detect what looked to be the correct level or return 0, hit or miss. It seemed to get better in later builds. before raw histo looked funny.

500D looks good :

I tried different even values without success and don't understand to hardcode it.
At least the 550D users can use zoom raw the way Shizuka discribed.
