    waterwingz, SD-card transcend 2gb.speed and class not known.lost about one-sixth RAW.Sorry mi bad english,im from ukraine :)
    Its a Class 2 then - the slowest card available these days.  If indraneel is using a faster card then that might explain why you are seeing the problem and he is not.

    I have a class 4 (Lexar multi use SDHC 4GB).
    DNG images are spectacular (not purple). Opens in PS CS5.1 etc.. Almost looks like those from the G10 or coolpix p6000...
    photomechanic fails to show dng thumbnail or preview. Since photomechanic shows only the embedded jpeg, I'm guessing the DNG does not embed the produced jpeg. Is that on the charts? Might be a big workflow help.

    !! Thanks to all, especially waterwingz !!

    1.00b
    Movie mode not working with or without raw selected. rec sign shown and then camera switches off leaving lens extended.

    setmode.lua runs and says pass, strike a key, and then finished. screen blinks, changes colors, icons flash etc during test. logs folder is empty. What should I be reporting?

    The "purple" RAW images are because CHDK RAW contains only the actual sensor buffer data - no header or anything else to tell your PC software how to interpret the data.  Most PC photo programs use the same library called DCRAW - which tries to guess what camera the RAW image was created with based entirely on the file size.  Obviouly this only works with cameras that the DCRAW maintainer have information about ( i.e. not recent CANON p&s camera ) and if two cameras have the same sensor size then their file size can be the same. In that case, even though the information they contain needs to be interpreted differently, the photo software does not know that.  And you get things like purple RAW images.

    New version :

    A800 1.00B Beta 2

    Added the 'PAUSE_FOR_FILE_COUNTER' - should fix the RAW file name save errors.

    Found and fixed a small problem in capt_seq.c .   Not sure it would have caused any problems.

    Double checked the movie_rec.c code.  Looks identical to the 1.00C version.  Can somebody confirm that the 1.00C works and would everyone else test to see if video recording works with the 1.00B ?

    Hmm, not sure on this one and to be honest I had never even thought to test video capture mode on the 100c XD  I'll test that sometime soon on my 100c (I don't have my camera with me right now else I'd test it now.)  So far as I know no work has been done to make sure the video capture works so odds are it doesn't ;)  Thanks for pointing this out!

    That's good :)  That's exactly what it should do - the screen will flash/flicker, change colors, show different icons, etc.  That means a core part of the scripting stuff is working, so that's good :)  As my Dad likes to say, "Sometimes it's better to be lucky than good" ;)

    To be honest, it's a stroke of luck that so much of this works - the DNG files, the setmode.lua scripting, and even just turning on for that matter!  Thanks waterwingz for making some 100b builds :D

    Just as a 'for what it is worth' - if you read back a few pages in this thread you'll find where I was doing tests with the 100c and getting purple .CR2 files but when I did .DNG files they were fine and there was a side discussion about image file headers and all that (which waterwingz summarized nicely a post or two back.)

    A800 1.00B Beta 2

    movie mode works for 3 to 5 sec. Then stops with a caution sign on top left exactly where 640 is displayed (this is a yellow stop sign with an exclaimation mark !). The movie plays ok with sound. Camera does _not_ switch off in the middle.

    Is there any way to set manual focus and stop autofocus from kicking in? I can set manual focus in alt mode but I cannot take pictures in alt mode. I can take pictures if I leave alt mode, but then camera auto focuses every time, unless I set AFL.

    What "Video Quality" level setting are you using ?   This tends to happen when the quality level is high - creating more data and larger files than the camera can write to the SD card as fast as it generates new data.  Try setting the quality level way down at first - less than 50.  I think for most class 2 SD cards,  values above 70 tend to stop in the manner you mentioned.

    Haven't played with that - but is more of a general CHDK question than an A800 question so maybe somebody else can chime in here.

    Alright back home, grabbed the latest autobuild for the 100c from http://mighty-hoernsche.de/trunk/ which is a800-100c-1.1.0-1792-full_BETA and tried out video mode.

    I set it to video capture mode, start taking video, and it starts recording - it pops up a thing in the middle that tells me the kb/s it is recording at.  Up and left it counts up the seconds and at around 14 it starts showing that yellow caution thing but it keeps recording.  I tried it again and again at around 14 seconds that yellow icon blinks at me.  Thing is, it keeps on recording and when I put the card in my computer I can play the video files and they keep going (I stopped at about 20 seconds.)

    I have been doing all my testing on a 2 GB PNY SD card because it's the one I have all set up with the hex editor to work.  Could I easily do the other method with the PS.FI2 file on a 16 GB Class 10 SDHC card?  Would I have to still tweak the hex thing on it?  (I've never messed with that firmware update method or whatever it's called.)
