Which DNG version have you selected?

Version 1.3 works only with newer Adobe products like Lightroom.
Version 1.1 is the better version vor other programs.

Choose the version 1.1 in the RAW/DNG menu. CHDK will prompt you to create the file badpixel.bin. You find a menu entry for that in the same menu.



'super fine' does not work for the SX220. There is issue with the memory management.

Hello,

I'm new here and I'm using chdk since yesterday. I have a question: what is the best way to save battery when making a timelapse with long intervals? (1 frame every 10 minutes). Can i shut off the lcd screen?

What's the best script to use for this purpose on the sx 220hs?

Thank you

As you might expect, there has been lots of discussion about this over the years.  Search this forum for "battery life".  These are probably the definitive works so far though :
chdk stuff - a590 power 1
chdk stuff - a590 power 2

Meanwhile, the general consensis is that you really need an external battery pack for serious intervalometer shooting.

Yes - as you will read in the links above,  either plug in a video cable or insert a wooden split to activate video mode.  Otherwise you can insert a set_backlight 0 into your script.  It needs to be after every shoot is take as shooting turns the backlight back on.    Either way,  you won't save a lot of power.  The camera processors and sensor use most of the batteries power - not the display.

The best one is the simplest one that does what you want.  Hard to beat the simple intervalometer script included with the CHDK distribution file and already on your SD card for that.

Ok thank you for your quick answer!

Unfortunately I would like to make a timelapse with the camera inside the waterproofcase WP-DC42. So it becomes a little bit difficult to have an external power supply.

If the processor and sensor use the most energy, do they use it only when the camera makes a picture?
So approximately the camera will make as much pictures when the interval is just 2 seconds or 5 minutes(of course a bit less) before the battery is empty? 

I'm just gonna test how long it takes before the battery is empty while the interval is 10 minutes.

I'm not sure how much difference it makes but taking a picture definitely draws more power that when the camera is idle.  And in the links I posted on the A490, the best battery life is obtained by switching from "shooting" mode to "playback" mode whenever you were not actually taking a picture (with the camera configured so that the lens stayed out when the switch happens).   With your 10 minute picture taking interval,  that could be very useful.

That sounds like a good place to start - no sense solving a problem that it might turn out you don't have.

@Tiz,
If you want to try to play the videos over USB from the camera on your computer, you will surely have problems to view them properly. The bitrate is extremely high on the original video (up to over 33 Mbit).
If that is the problem, download the videos from your cam and try again. For me, VLC Mediaplayer (Videolan) works great and without stuttering.
I personally like the 23,976 fps much more than the 30fps from the sx200is. If you are using PAL on your TV, there is only one frame/sec added to the PAL specified 25 fps. On 30fps 5 frames were removed to meet PAL specs and that is really horrible.
I don't think that the monitor refresh rate has anything to do with your problems.
Not heard of such problems until now.

Try to convert the video into another container format like avi, mp4 or mkv. Most systems have problems with the mov container. You don't have to touch the h.264 video stream, only change the container.

The SDHC or SDXC Card can make problems too. For me, Sandisk Extreme 16G with 30 Mbit/sec works great ;)

You you use AppGeeker Video Converter - Handles MOV to MP4 conversion well, and can convert videos to any other video file format.

Very simple to use.

I have a problem with the SX220 grid and people said me to post it here cause its a bug.
The problem is that shooting at 3:4 ratio the grid is also at 3:4 ratio but aligned to the left and the camera live preview image is alinged to the middle of the screen. thx Paul
