CHDK NEWS: Ported to more Canon P&S Cameras, New CBR Video Compression Options
See this page for further details about anything mentioned below. http://chdk.wikia.com/wiki/CHDK New Cameras Supported: Canon Powershot A560 fw v1.00a Canon Powershot A570 fw v1.00e Canon Powershot A720 IS Canon Powershot SD500 fw v1.01a (IXUS700) Progress has also been started on porting it to the following models: SD300 SD700 S5 IS -- Yes, a way was found into the previously locked-out new models, or at least the S5 so far. This may mean it might be possible to also port it to the G9 and SX100 in the near future if there is more success with the S5, all being new Digic III models locked out in a similar manner. New Constant Bit-Rate (CBR) video compression options found and implemented by EWAVR See this discussion page http://chdk.wikia.com/wiki/Talkownloads Test builds available for: A570 v1.00e A610 v1.00e A610 v1.00f A620 A630 A640 A700 A710 G7 v1.00g G7 v1.00i G7 v1.00j Ixus 700 (SD500) S2 v1.00e S2 v1.00f S2 v1.00g S3 IS (works great on mine so far!) You not only have compression ratios of 1 to 99 for VBR mode, Variable Bit Rate (constant quality) as before, but you now have an alternate option of CBR mode, Constant Bit Rate (variable quality). With CBR settings of 0.25x, 0.5x, 0.75x, 1x (standard), 1.25x, 1.5x, 1.75x, 2x, 2.5x, and 3x. (the higher the number being the higher the video quality, the higher the MB/s.) Note: to use the Quality (VBR) compression settings above 95 or Bit Rate (CBR) settings of 2.5x or higher you will need the fastest SD cards you can find. You may have to also lower your audio sampling rate if you want to be able to sustain such high video data rates without hitting buffer overrun problems. You may download these test versions from the "/for_test/" link in the opening paragraphs on that discussion page (link above). New uBASIC scripting commands available for faster and simpler loops and more complex if/then/else/endif multi-command constructs. See Fingalo's CHDK2 page and the two "Special Builds" sections on the Scripting Tutorial page for further details: http://chdk.wikia.com/wiki/UBASIC/TutorialScratchpad To make full use of the more complex and in-depth "get_prop" and "set_prop" uBASIC commands by Fingalo be sure to see the ongoing investigation into this low-level-access feature in this discussion area: http://chdk.wikia.com/wiki/Talk:UBAS...ration_section And this page of now-known Property Case ID values: http://chdk.wikia.com/wiki/PropertyCase By using the "get_prop" and "set_prop" commands you have almost complete access to all internal features and flags being set by the camera at any time, for use in any of your own automated scripts. Anything from setting custom color modes, sharpening settings, and even setting auto-exposure bracketing steps up to 4 or more f/stops per 3-shot bursts, in 96 available EV steps per 1-stop increment. Example use: one simple script can give you 6 fast HDR exposures of 2 stops apart for each exposure. You can even alter auto-flash intensity in 96 steps per 1 stop increments (the amount of full 1 stop increments for flash not fully tested yet). There is more accuracy and capability in these cameras than anyone ever first suspected. If you are new to writing CHDK scripts be aware that these "set_prop" and "get_prop" uBASIC scripting features/commands are for more experienced script-writers. It would be easy getting lost in their subtleties and co-dependent complexities until you are familiar with the more common uBASIC camera control commands and uBASIC syntax on the scripting tutorial-scratchpad page. If you have a Digic II or Digic III camera that is not supported yet be sure to check out the revamped "For Developers" pages http://chdk.wikia.com/wiki/For_Developers With your camera and your effort you might be the first on your block to add your camera model to the growing number of CHDK supported cameras for everyone on earth. |

CHDK NEWS: Ported to more Canon P&S Cameras, New CBR Video Compression Options
Kevin, given your frequent posts and fervent support of this software,
when are you going to post some actual *examples* demonstrating your use of chdk? |

Personally I don't mind being kept up to date (I'm waiting for the version that will support my camera's firmware, I'd really like the RAW function). Fair comment, Neil. I'm just having a little dig at "Kevin", who has some 'interesting' posting habits on usenet. You may not have recognised him elsewhere, but let's just say his views are often stridently given... If I was the author of CHDK, I would want someone else doing my advertising... (O; |

He'll probably do that just as soon as you post anything more than highly immature attempts for attention. Neither of you should hold your breath waiting. |

They seem to have been able to download the firmware from the camera, but there is no CHDK build for it yet, unless I missed it somehow. True, a misread on my part. I mistook a report that the A720 firmware was finally available for download (for analysis), not the working ported binaries. Just as you state. It appears now that the A650, A720, S5 IS, G9, and other Digic III cameras have been compiled and are working on a whole other OS (DRYOS vs. VxWorks). While it is possible, CHDK is going to have to be re-analyzed from square-one to make it work with them. Due to the overwhelming benefits of any camera that can run CHDK I suspect it will happen, it's just a matter of when. Winter is a good time for the less adventurous photographers to find something else to do with and for their cameras. New CHDKs might be part of their snow-day activities. When I think of the leaps and bounds that CHDK has taken in only the last 6 months, ever since that first little binary that allowed people to only save RAW files, and on only one model of camera at that, 17 different cameras supported presently. Now it's capabilities are all the way up to a selection of 7 different full-color live histograms, Zebra's real-time under/over-exposure areas flashing in your EVF/LCD (in 6 different flavors and 255x255 different color options, with user selectable under/over limit settings), programmable motion-detection fast enough to capture lightning strikes, an unlimited number of cropping and composition grids, an inexpensive and 100% adaptable USB remote trigger, on-screen DOF calculations, full-frame high-speed stereo photography done with two cameras linked by USB (all automated)..... I could also mention the fun things like having a 10,000 e-book library on one SD card to read on your camera's EVF/LCD while on vacation, but that's not photography related. Aside: with the right font converted to RBF format it's actually pleasurable to read an e-book using your camera and CHDK, I used it for that while tanning this summer. (I've also already found a way to use my camera as an MP3 player but it's a too-clunky work-around when MP3 players are so small and cheap now.) .... I've no doubt that CHDK's availability and capabilities are only going to grow exponentially. As it already has. It's becoming difficult to even keep up with the weekly changes and new findings, huge sections of the Wikia pages haven't even been updated with all the new features in the last month. (We're too busy playing with our cameras' new, and until now unavailable, capabilities.) People once thought that new video compressions were impossible. Now we have 98 VBR options and another 10 CBR video quality options to choose from. Some of such high quality that even the best SD cards available can't keep up with the bandwidth needed. Need I mention the new set_prop scripting command that allows me to take +/- 4 or more f/stop brackets, in high-speed multiples of 3-shot EV brackets, with each f/stop in increments as fine as 96 steps if wanted? Or unlimited automated DOF bracketing? I've yet to delve into the 96-steps per f/stop flash-output options to fine-tune the flash for macro-photography. Using a simple script it could read the camera settings automatically to set the flash for the macro-photo distances. Or for high-speed photography studies that were once only the realm of the laboratory. (Flash output intensity is controlled by flash speed, the dimmer the flash the faster the relative shutter speed.) The unlimited precision intervalometer options is child's-play compared to the new things that CHDK cameras can be now be made to do. CHDK is already well past the "HOLY F'n WOW!" stage of development. I don't think the camera designers even realized what their cameras could be made to do, nor how many have been waiting so long for something just like this. |

The designers certainly knew, but to include all that capability implies supporting all that capability, including software upgrades when bugs are found, and of course delaying the product launch until all the software is completely written and tested. You can't really blame the manufacturer for being reluctant to include all the capabilities on the lower end cameras, when so few users would ever use the extra features. |
