Thanks.

For cameras with a playback pushbutton, these parameters seem to work :-

RECORD    0x1001
PLAYBACK 0x1003
MOVIE       0x9A5


Cannot get it to work on the A550 though.

Hi All,

Do you think HD video recording can be enabled on the SX10? I think the difference between SX1 and SX10 is only the sensor and the SX200 can record 720p video with a CCD sensor very similar to the one in SX10.

Also, can faster continuous shooting rates be enabled by CHDK? As the camera can do about 3.6fps in ISO3200 mode (2MP) it seems that the 1.4fps limit in all other modes (including regular 2MP and even 0.3MP) is a limitation imposed by the firmware.

Some investigations about 12-bit RAW.
I inspected pixel values statistics for SX10 using show_stat program.

You still think that the 12-bit ADC means 12-bit measurement accuracy?  :haha

SX10 1.01A updated: added wheel support, multipartition support, RAW sum/average for 12-bit RAW (to do: curves and RAW subtract  for 12-bit RAW).
Forget about video bitrate change (no MJPEG inside?).
Binaries + scr: http://ewavr.nm.ru/chdk/for_test/

Wheel support & multipartition setup (8GB, 2MB+ restMB) with swapping via menu works fine, also the 3rd ALT-shortcut (video button)  :)

But it seems to be 10 bit, still better than the 8 bit JPEGs.

SX10 1.01A updated

Also successfully tested:
- Power on in record mode (hold power btn)
- MD (fudgey's MDFB-080914), ~85ms most time, rarely ~100 ms reaction time
- Tv bracketing (- mode, + mode, +/- mode)
- Subj. Dist. bracketing
- LED's (all working)
- User menu (uses the AF frame selector / Delete button for selection)

Updated again - RAW subtraction is patched for 12-bit support, some minor fixes.
Curves are removed from this build, because I have no idea how to patch it for 12-bit support.

@fe50
Many thanks for testing. Since I'm newbee as CHDK user, I can't test all its features  ;)

that does not work:
- Auto NR with shutter speed override;
- shutter speed override (and maybe other overrides), if shutter button is pressed quickly.
So far, I have no idea how to fix it.

Probably fixed, but more testing is required.

Not fixed, but if shutter is pressed quickly, NR works correctly.
Files are updated.

i'm reading ALOT of reviews about the sx10 lately, and all of these reviews come to the same conclusion: remarkably good camera.
if i hadnt invested in my slr system, i think i would already own a sx10 by now. what is a good camera + chdk? a VERY good camera.
great job, ewavr, and all those who contributed.
