Canon S3IS Force HD

It's 2022. There has got to be way to finally force Cameras to either record lower resolutions than what they usually record videos at, or maybe even make them record higher quality videos than what they come with. Why is no one trying to do this? It's 2022 now... There's a lot of improvements going on with photos, but barely anyone wants to even try touching the code for video generation in these cameras... Why???

Even the following S5 IS with 8.0 MegaPixel is VGA only.  :(

Consider what you are wondering about.

It's 2022 now. There is got to be a way to finally force that A-Ford to become an EV with ABS, airbags and powered windows.
Why is no one trying this? :)

I might write software that tells you that A-Ford lists those capabilities.

But the way it has to be done in real life.....by replacing almost the entire car with something from 2022 is harder.
And would it still be an A-Ford or something that just looks like it?
So if you are willing to gut your S3IS and refurbish it with modern stuff it can be done ;)

Software can only work with the available hardware. If that hardware is not capable of performing the task, no amount of software can force it.

But are we sure it's impossible? Maybe we can push it beyond its limits...
The SX40HS could never zoom in while recording Slow Motion Video before. However, after a new script was written, it actually opened up this capability, that shouldn't have been possible at all.
Who is to say that overriding the resolution isn't possible? Maybe even for 15 seconds of HD video before the RAM is filled?

the same hardware, but a 6 fold data stream?
maybe by upping voltage to the processor to clock it higher and with liquid nitrogen to make it survive that? :)

No one is stopping you from doing it yourself.

After you've spent a few years learning how the technology actually works, and reverse engineering the Canon code come back and tell us how you got on.

Are we sure it's necessary to overclock the processor and all that stuff? I managed to make the Canon SX40HS zoom in while recording slow motion. A feature that was supposed to be impossible... Apparently, it shouldn't even work, since the processor at this point is focused solely on the Slow Motion recording, and shouldn't have enough power to initialize a zoom in... And yet, it somehow works...

Whereever is need to build house around o: within cam, forum has parts for solution  :D

Set Date to 2037, might detect yet hidden future updates ... :lol

Who said that was "supposed to be impossible" ? Moving zoom while recording (whether slo mo or not) is not remotely in the same category has recording HD on a system that was never designed to record HD. Zoom is telling an actuator to move, which requires negligible CPU cycles. Recording HD requires vastly more CPU, memory, and IO bandwidth, which are fundamentally defined by the hardware.
Canon would have been very foolish indeed to spec a camera with enough power to record HD in 2006, and then not sell it with HD capability.

Those of us who work on this stuff generally work on what interests us, or what we feel is necessary to support the project.

Anyway, as Phil suggested, you're welcome to download the source, fire up ghidra and try your hand at reverse engineering. You may find that substantial time and effort are required to learn the necessary skills, and that once you have them, the work itself also requires substantial time and effort.

Congratulations - you found a script written in 2015 that enables a trivial and pointless feature on the SX40.


No one ever said this was impossible.


The camera is unable to adjust focus or exposure when recording slow motion video - zooming in changes both the focus distance and aperture so without the ability to adjust focus or exposure your slow motion video will go out of focus or get brighter or darker depending on which way you zoom.


If Canon had allowed zooming during slow motion video then customers and reviewers would have complained about the focus and exposure problems in the resulting video - so Canon chose to disable the zoom feature.
