Fast MD with burst/preview mode

[letank]

just installed 411, the older version on a A720IS..... works very nicely..... Need to set the specs.

Now i can see who is dumping animal waste in my front yard.

Great job

[letank]

version 716 is working as well on the A720IS w allbest 50.

But in fast mode only, in slow mode it takes one shot after MD, then the LCD goes to sleep after 1min (same w older version) The timeout is set at 10 mins.

It may have to do w the focusing.... the green light does not lit in slow mode after the first pict is taken, it does not even blink orange.

At least the weather has been a real San Fran classic: thick fog... so no dog walkers has come to let the animal take a $%# on the grass.

In fast mode the script keeps shutter half-pressed while detecting. In slow mode it doesn't. Thus it does not focus until it detects and no LEDs will blink during slow mode MD.

Set "Disable LCD Off: Script" in CHDK settings to prevent the camera from going to LCD power saving mode.

Yet another new version. If your current version works fine for you, there's no need to upgrade. Also, you'll probably need to upgrade your CHDK to use this new version, because:

This version uses ubasic commands currently only available in recent juciphox builds, which even more recently became the mainstrem CHDK flavour, see this thread: http://chdk.setepontos.com/index.php/topic,2297.msg21224.html#msg21224.

I repeat: this new MDFB version requires a shiny new version of CHDK.

If you are using an older build, use an older MDFB version.

The script is attached to this message. If you can't see the download link, you need to log in to this forum.

This version has only been tested on a570is, and quite briefly. It would be nice to get some test feedback at least from an S2/S3 user, an S5/TX1 user and a Digic II propset ixus or A series user.

Changelog:

MSDB 080914:
- Now requires the new CHDK juciphox-allbest-trunk version, build 509 or higher (if your CHDK is older than September 14th 2008,
  it is likely not compatible).
- No more separate versions for the two propsets (Digic II/III) thanks to the new universal commands replacing get_prop commands. Models with a separate video button still have their own version. Each version now outputs an error if you try the wrong one.
- For models with no video button, video/still mode is now autodetected from mode dial position and thus the still photo/video parameter has been removed.
- Added commands to release shoot_half after taking a photo. This fixes operation on IXUS750 and IXUS55, likely some others as well. On most cameras releasing shoot_full was sufficient, but apparently not for all. This change shouldn't break anything and it doesn't slow the script down (it adds 10 ms to post-still-shoot operation (not reaction time), but the propcase wait loop is probably equally shorter now, so re-arm is probably just as fast as it was before).
- Ends immediately if attempted to run in play mode.


(And before PhyrePhox asks: Yes, there's still two versions even though the video button can be (and is) tested by the script. The video button models still need a script argument for choosing still/video mode. I don't want it shown in other cameras as it would confuse users since it's actually autodetected but AFAIK I can't remove it using script commands).

Thanks, you rock,  it is working! Cannot wait to post over 5 times to give you good karma.

It has been a fun year.... I dumped Windoze for Linux, almost: GPS is non op yet, anf chkd is op... discovered it last year.. but did not have time to read all the details.

I shot these last night with an S5 IS using "MDFB-080716-DigicIII-MovieButtonModels.bas"

enjoy

Hey Falchor,
Does your S5IS crash when using MD with video capture set at the 640 with Jucifox builds
Original Allbest #51 works fine but juciphox just wont do it.
This is the main reason I use CHDK is for surveillance but cannot use the latest build,really annoying.
I've tried all the MD versions but same result

did you try disabling your lcd monitor and setting to script?

"did you try disabling your lcd monitor and setting to script?"

Yeah tried,"script,alt and no"
I'm fairly sure the new CHDK video settings are screwing it up but they are not implemented in the S5IS,untill they are I think this problem will stay.
I have no video settings in the chdk menu,what I've been told this is normal,but strangely,recording video normaly I can change the bitrate,but it has no effect
I'll stay with Allbest #51 till things get sorted out

Im trying to get a nice shot of  shooting a lightbulb with a bb gun.
3 bulbs in and it kinda worked... need to not zoom in as much so i get some chunks of glass .
quick question tho a720 is  how do you turn off noise reduction ?

If you want to try to catch the bullet hitting the glass or the very first milliseconds after impact, you'll need to make the camera trigger well before the bullet hits. That needs some setting up. You can use MD to trigger from something other than the bulb (like a flashlight in the scene somewhere) or USB remote trigger (my recommendation), either setup fired from e.g. your gun's trigger. Or for a quick fix, try putting a balloon in the bullet's way, it probably has enough energy left to break the bulb after. May not help enough, though.

quick question tho a720 is  how do you turn off noise reduction ?

In CHDK RAW settings menu. It only turns off dark frame reduction, though, but that's probably what you ment.

I use S2IS & CHDK Autobuild 0.6.6, revision #544.
I put 'MDFB-080914-VideoButtonModels.bas' in the script folder of CHDK.
I tried to load the script (main menu>scripting parameters>load script from file)
Nothing happens.
It seems the .bas is not recognised by CHDK

Are you actually starting the script? In normal REC mode, press and release the ALT button and then shoot. See wiki for general CHDK script usage instructions.
