I have the same camera and firmware as mojo43 . Like to try patched chdk version if it could work better with this camera? But the download link is dead...

Me too. I want to download the patched chdk version but link is dead.
The link was for an experimental build - I don't keep those around for long.

The philmoz patch file used to create the download will not apply cleanly to the current build and I don't really have time right now to fix that.

So here's a rebuild of the stuff you asked for using the older version of CHDK it was created for :
ixus220_elph300hs-100c-1.3.0-3344-full.zip

I can build for other cameras but this is a time limited offer

Thank you waterwingz.
I go it and tested on Ixus 220 / elph 300HS and Video Exp Ctrl v3.5 (videx3.lua):
I installed the rebuild on a 4GB SD card with card tricks.
The script videx3.lua (v 3.5) does not need native lua calls enabled with this patched rebuild.
During video capturing with the script Tv (speed control) works and Sv (ISO control) also works.
Av (aperture control) does not work as reported above in previous comments.

I can make a comparison on this camera with the previous version of Video Exp Ctrl v3.4 (videx3.lua):
With Video Exp Ctrl v3.4 you do not need a patched CHDK build, but lua native calls must be enabled.
Even though, Tv (speed control) does not work , Sv (ISO control) works and Av (aperture control) works but gives you only two aperture values.

For both versions(Videxp3.lua v3.4 and 3.5) I can say that they enhance video capturing because they both expand ISO control: you gain higher ISOs.

Thanks waterwingz!

This build works with v3.5 script like mercier wrote.

I don't like the way my ixus slightly overexposure videos and this gives tools to fix it.

I've lost track of what works and what doesn't. I'm traveling this week and not able to do custom builds. Does the standard script on the wiki not work for you?

ok thanks, i'll make do. just thought if it was less buggy then it might have been nice sort of thing.

ive updated now my chdk from 2014 June to current stable today now.

did a little test with videxp3.3 which i have and it seamed ok. did crash when i pressed the play button i think but when i half pressed shutter before pressing menu or other button,i’ve just forgotten which other button it was... seams that what someone said was that you need to half press the shutter button before exit for it to not crash the camera?

the wiki only has version 3.1 and the download link is dead. good thing i have 3.3

. now you mention it, does anyone have a copy of this 3.4 version people seam to be talking about? I’m not sure what it’s benefits are?

thanks muchly, time for some sleep

The text copy of the script on that page is 3.1 The copy available from the download link is 3.4.

I just tested that link and it seems to work fine for me

First at all, this script is the real deal! One of the most useful scripts ever written for CHDK, no doubt. I'd like to personally thank Waterwingz for the hard work done & taking into account the suggestions above, making the script even better. Thank you so much.

Also I'd like to report that my SX230 works really well with that one.

The only thing that bothers me is the loud noise of up & down buttons, which is easily heard on record. Since my SX230 have these buttons merged with a turning wheel, that of course makes less noise, I decided to take a try and set the up & down commands to a wheel turn.

As a newbie in script-writing, I can take a guess that these lines 'is_key("up")/is_key("down")' are standing for up & down commands and insted of 'up' and 'down' I need to desribe a left & right wheel turn, but I coun'd find a name for that command. Please, does anybody know? Or CHDK doesn't support wheel as a button mechanism? Thanks.
