Thanks for the quick reply. The script worked without errors.
The images have different parameters (2nd one has faster speed, 3rd one lower iso).
In general it seems stable enough. The functions I tried seemed to work. There are of course a lot of options that I'm not familiar with as I haven't played much with my SX100 in the past four years (still had it on the 1.3 branch) and CHDK seems to have added even more options.
Let me know if you have more things to test.

Thanks again. I switched the build status to alpha.
Don't forget what the H stands for.

waterwingz - Thanks.   It looks like the grid files have hard coded values for a smaller display. 320x240. Once I made a new grid file, it worked fine.


just discovered that the sx700hs is starting to be supported


my camera has firmware 100d


could you share a grid file you have changed for this camera please


or can someone tell me what size the screen is on these cameras


thanks

The screen is 640x480 when using the LCD. Note that pixels are square, unlike on earlier cameras.

Hi,
while beeing very long time user of CHDK on my Powershots I'm very grateful to the developer team.

Testing the build CHDK_DE_sx700hs-100e-1.5.0-5596 on my SX700 I've found so far the following issues:

script command set_focus -1 (or any high value near to infinity) does not work, however this issue was discussed on different other topics already.

CHDK OSD in video mode: displayed values seem to be sensless: "0001 kbit/s" (sometimes vaues up to "0004") or permanently "00:00:01" if video time remaining should be displayed.

Override ISO value via CHDK menu: works fine if values below the minimum value of Canon standard (e.g. 50 ISO) are choosen, however it fails if the Canon standard was set to values between 400 ... 3200 ISO (all PSAM modes). In this cases the camera switches of if the shutter is pressed. If ISO should be pushed bejond the maximum standard of 3200 ISO the use case would be: setting this maximum value via the Canon menu and than use the CHDK override ISO in combination with a -1EV correction (in case of 6400 ISO) via Canon standard menu in order to obtain correct exposure. Btw, using the EV correction from the CHDK menu where values from 0 .... 4EV can be choosen, does not have any influence at all on the exposures taken.

Would be happy if one of the CHDK masters will go after this issue at one of the next builds.

But staying healthy has priority currently ....

CHDK OSD in video mode: :( core/gui_osd.c line 581
            // D6: filesystem related info is not updated during recording

" In this cases the camera switches of if the shutter is pressed."  ???

Thanks for the reports.

Different cameras have different limits and issues, so it's not clear if this is a bug or expected behavior.

This camera requires MF or AFL enabled (either with the Canon UI or set_mf or set_aflock) for set_focus to work at all. In those modes, calling set_focus should immediately update the focus distance.
You can use the DOF calculator to show the current SD value, under OSD settings->DOF Calculator
set "Show DOF Calculator" to "in misc"
check "Show Subj. Dist. in Misc."

The port is configured so that 1562414mm is largest non-infinity value that can be set. Values beyond that should result in infinity. However, at the wide end of the zoom, it will go to infinity at much lower values (my sx710, which I think has the same optics, shows infinity with set_focus(10000) at full wide). Setting -1 should set focus to "infinity" but that may actually give you the best infinity focus.
Additionally, set_focus only focus at certain steps. On my sx710 at full wide, setting 4000 to 9000 all result in SD around 5000.

Yeah, these cameras don't seem to update free disk regularly while the video is recording.

Do you mean 400 to 3200 in the CHDK override value, or that the Canon UI is set to those values, while a different value is in the override?

As caefix said, a posting a romlog would be good. See https://chdk.fandom.com/wiki/Debugging#Camera_crash_logs_.28romlog.29

Note that values beyond the Canon limits may not crash, but they probably don't actually set the ISO much beyond the Canon limit. That means that ISO override is really only useful for script, or for Canon settings that restrict the ISO (for example, many cameras force low ISO for long exposures)
Don't forget what the H stands for.

The use case is: setting e.g. ISO 3200 via Canon UI and ISO override to e.g. to ISO 6400 via CHDK, leave CHDK and press shutter. Would expect either an overexposed image or - to avoid that - would have to set a -1EV exposure compensation via Canon UI. However pessing shutter results into a camera shut down. ROMLOG.LOG attached.

To be more presise on this topic: setting e.g.100 ISO via the Canon UI and e.g. 50 ISO via CHDK Menu and leave CHDK. In this case the camera takes an image if the shutter ist pressed (no shut of) and the EXIF data of the image ist updated to e.g. 50 ISO. In this case I would expect either an underexposed image or would have to set a +1EV exposure compensation. However the image is NOT underexposed but exposed like 100 ISO to stay with the example.

This type of use cases work like expected on all my other Powershots with CHDK, at least as long the HW limits of this particular cams are not exeeded.
