Hello, noob here. Just installed CHDK and enabling optical magnification on video yields less than favorable results...I have found that the magnification works, however I cannot retract it. What's interesting is that when I switch to image shooting mode after, the optical magnification button does not work either. I have found that entering image review/playback then back to shooting mode fixes the problem temporarily until I try it again. Conversely, optical zoom works as normal on the image shooting mode.
Did I do anything wrong in the installation? I would chalk this up as an anomaly however there is a youtube video by @rhcrcgvp showing a CHDK SD1400IS demonstration with optical zoom working as normal. I am stumped, and any advice is welcome.
Just to confirm: You mean, if you start recording video, you can zoom in with the optical zoom, but cannot zoom out again until stopping and switching to play?
Extremely unlikely to be a problem with your installation, more likely a bug in the port. There's two supported Canon firmware versions, 100a and 100c? It's possible the bug is only present in one port.IIRC there was a fairly common problem something like you describe that was straightforward to fix, but more modern cameras have zoom unlocked by default so it's been many years and I don't recall the details offhand.
That's strange. I'm seeing here that my camera is running on firmware 100c, but I might be wrong so I'll link an image below.
Though, the demonstration video on youtube showed that OP was running it on firmware 100c too and his was working fine. Then again that video is also 12 years old and was running on a then unstable version of CHDK so something must have changed.I'll try running the unstable version of CHDK tomorrow and I'll post again to see how it goes.
There could be other camera settings that affect the behavior. Looking back, one of the issues I remembered involved digital zoom: The zoom would stop working if you went from optical into digital. This could be affected by Canon digital zoom or "digital teleconverter" setting (I think these are all a single setting on your cam). I'd suggest testing with that off in the Canon menu, if it isn't already.
Huh, I feel a bit silly now. Just tried it again and it worked. I thought I had tried out these tests with digital zoom off but I was wrong, and turning off digital zoom did indeed solve the optical zoom issue. I don't think I'll need to load up the previous builds anymore. Thanks.
Here's a test build with a workaround used for the same (or similar) issue on other cameras of this generation. Please check if it works when digital zoom is enabled.
Sorry for the wait, yes it does indeed work like a charm.
I'm also not very tech savvy with these kinds of things, but I just copy and pasted the zip contents into the SD card and overwrite the same-name files as needed.
