This talk page is not a good place to ask for help with CHDK. You are much more likely to get an answer if you post your questions on the CHDK Forum

Forum Down?

Hi CHDK members,

I just noticed something: When i try to enter the Forum, it tells me that "this account has been suspended"

I just wanted to point it out to be sure something is done.

Modifying exposure parameters during video recording


In the manual it's not mentioned if it would be possible to modify the exposure parameters during video recording (increasing/decreasing automatic exposure value e.g. in case of high contrast scenes) Thanks for any hint!


Unable to Load CHDK on Canon PowerShot A470

I can't seem to access CHDK on my camera. I think I'm doing everything right. Please Advise!

When do you thinnk that CHDK version for the SX20 will be removed from Beta?

CHDK port for Canon SX30 IS

I understand that currently there is no support for the SX30 IS, however there is support for the SX20 IS. I own an SX30 IS and was wondering what I could do to help expedite the port to this camera? I was also wondering if the current firmware hack for the SX20 IS could be easily modified to work with the SX30 IS? If there is a developer I could talk with about this particular model please reply.

Full Resolution Stills while recording video

Does anyone know if CHDK will enable any of the cameras with the dedicated video record button on them to capture a Full Resolution Still while recording video? This feature is on the Canon TX-1 natively and is VERY useful. I really like the features of both the SD4500 and the SX210IS, but when you press the shutter release during video record it stops the recording completely and takes a picture, you then have to press the record button once again to continue recording. Any help would be appreciated, including, but not limited to, possible alternative cameras that are 10X plus zoom, record HD video, and can take full resolution stills during video record.

SX1 IS -> RAW photographs don't work


With the newest (2010-12-19) CHDK version the RAW photo function doesn't work on the SX1 IS.

In fact a 16.4 MB CRW_xyz.CRW file is created, but it's not filled with readable data. All Picviewers reading CRW/CR2 codec normally show a picturesize of 0x0 pixels and quit with an errormessage by opening such a file.

Any ideas?


Mit der neuesten Verison von CHDK (19.12.2010) bekomme ich mit der SX1 IS kein lesbares RAW Format auf die Karte. Es wird lediglich eine 16,4 MB große Datei auf die Karte geschrieben die aber nicht lesbar ist. Alle getesteten Fotoviewer melden eine Fotogröße von 0 mal 0 Pixel und bringen eine Fehlermeldung beim Versuch eine solche CRW/CR2-Datei zu öffnen.

Irgendwelche Ideen?

Ansonsten: Gute Arbeit Jungs!

Gruß, Matthias

Microphone Disable on SD700 IS

I need to disable the microphone on a Canon Powershot SD700 IS. I use the video mode to record images of land that I have for sale from time to time. The wind noise from outside makes it difficult to post a decent video on YouTube without sounding like you are in a storm. Is there any way to disable the microphone using CHDK 14:41, March 11, 2011 (UTC)

Which camera?


I'm new here and want to ask which compact camera (older or newer) would be the best choice to profit from all the functions CHDK? (RAW, Bracketing, Motion Detection)

CHDK for Sony a33/a55 for all documentary filmmakers?

Hi there,

I know the Canons have their advantages, but for documentary filmmakers which run on the field, the option to use a DLSR with follow focus, which records long time video sounds just too good. The biggest and only real crucial drawback is that it records at only 16Mbit, so the picture is only usable if the sun is shining and no fast movements and light changes happen. Naturally this is the case in documentary field work. Magic Lantern made it possible to change the Bitrate for the Canon cameras quite easily it seemed to me from the instructions. Is there any chance to make that possible for the Sony a33/a55 as well? Is anybody working on it already or interested or looking for someone with special programming skills to start working on it? Please answer on this post then. Any help would be highly appreciated by the documentary filmmaker world. Thanks a lot.

I was wondering if there is a port to the Elph 310 HS that is in the works. I couldn't see one.

Elph 310HS Port?

I was wondering if there was a port to the new Elph 310HS in progress? I couldn't find it.


Porting has just started, look at ELPH310, there you'll find a link to the porting thread:

Please participate in the porting process. If you have no software/programming skills please support the porting process at least by testing as much as possible and give as much feedback as possible to the developers in the porting thread.

SX 130 IS ver 1.00b required

I have sx130is ver1.00b. I wish any body can develop the chdk for this version. I am very crazy finding FW of this version but yet to wait to publish. Any one plzzzzzzzzz14.96.3.244 14:34, February 26, 2012 (UTC)

Access SD card in picture taking mode

I am planning the following application:

- a camera should continously take a picture every few seconds

- while in picture taking mode I would like to access the SD card over USB from a computer to download and delete the latest file

Is there a way to do that with CHDK? I have a PowerShot A540 with CHDK and I could not figure out if this is possible or not. 19:14, February 29, 2012 (UTC)

Ixus 220hs ver. 1.01G

I own a Canon' IXUS 220 HS'but the hack does not work on this. My version is 1.01G... when it comes out a hack also works for this version? Thank you.

primary.bin file ???


I want to make my SD card bootable with the "SDMINSTE" program.

But how does the step work? I

"Unzip the primary.bin file from the CHDK distribution file to the root of the FAT16 partition on your SD card"

I hope to hear from you.



  • typo, fixed now; the file is named diskboot.bin, not primary.bin...

I have a CANON PSA3100is. but i can't find CHDK firmware for thisin your list.

can I have one? or does CHDK firmware for PSA3000 is also work for PSA 3100is?





Thank you for the wonderful software! I just purchased a Canon Powershot A3400 IS and I was wondering if there were any plans to create a CHDK firmware for this camera (or if any of the current firmwares work with it)?

Thanks again!

Does anyone know, if it would be possible to hack a camera to record video in a resolution of 1 pixel wide x max width (a 1px line of horisontal pixels)???
