Any chance you know how to write a script to start video and to lock exposure so it is not always changing ? There are quite a few people that would really like to have this working...

thanks in advance.

Not off the top of my head.  I don't use video with my cameras but I guess a lot of people do.  The script writing is the easy part - I just don't know if any of the set_TV() type functions do anything while you are in video mode ?

I have been trying out different combinations with this script (http://chdk.setepontos.com/index.php?topic=5295.45) and the lock seems to work but the problem is that every time the camera moves it seems to reset and turn off the AE lock. I could be wrong about this, but I am not sure where to go from here.... Thanks for your help anyways...

Oh and by the way, the video on this camera is fantastic! I am pulling really high bit rates and the quality is great!

Is there a function for AE lock in bas?

That's a very technical script - it will take a lot of work to improve on it.  Not sure what else to suggest assuming you got the right addressses in stub_entry_2.S for your camera model.  Sorry.

I got the addresses from this page (http://trac.assembla.com/chdkde/changeset/880), and as I said it seems to work until the record button is pressed and there is movement. Thanks for checking it out... I guess I will have to wait until someone with a greater knowledge in this area looks at it.

Thanks again...

Sorry if I'm still here to ask questions.

Is there a way to extend the battery life? Changing an external battery pack for example, or something like that

Any news about exposure lock during video ?

i am really anxious on buying this camera and my retailer is going out of stock .

Can someone tell me if exposure lock for video is just a matter of time or there is the posiblity that exposure lock will be imposible for this model ?

For whomever is interested, I used Adobe's Lens Profile Creator to create a profile for DNG shooting for the ELPH300HS.  It is by no means perfect, but with some minor adjustments in your RAW program, it's not too bad.

http://dl.dropbox.com/u/14988694/Canon%20PowerShot%20ELPH%20300HS%20%284.3-21.5%20mm%20f2.7-5.9%29%20-%20RAW.lcp

Further distortion, vignetting, and color correction are in this file:

http://dl.dropbox.com/u/14988694/barreldist.xmp

I've found that it does have a bit of an orange tinge to it, but it seems to get the colors pretty close to what  the ELPH300HS JPEG processing looks like [and in some cases, more accurately captures the colors in the scene].

(Also, I'm a newb with all these different file types, so if I posted some that aren't actually anything, just let me know)

Hello everyone.

Does anybody know if there is an effective motion detector for the ixus?
I tried many of those which are on the scripts page with no success.
The aim is to take pictures of birds. But if it's possible to set the script for lightning too, it would be awesome.
Sorry for my poor english and thank you in advance.
