Software Dev / Re: Updating the UI: Network / Remote Control Screen

We figure that connecting via the microusb cable is a special case. Since you have to be physically present for this, you always get access to SSH and the remote control app this way. You connect your computer to the camera via USB, visit the URL it says to, and it should "just work". SSH will ask for a password, but the remote control app will not. This is non-configurable, and will always work, and will definitely be mentioned in the manual.

Good choice! "It just works" should always be the goal

Since the default is now to *not* allow SSH from the internet, I'm comfortable with simply setting a password for SSH. You should still use key-based authentication for SSH if you allow access from the wider internet, but you can turn that on from the command-line.

How are you actually checking that the connected interface is "just" LAN? I'm not too familiar with "advanced" network setups...

Other than that I prefere version 4! It has a sowewhat clearer outline. Will there be an additional screen to manage certs or will whe have to set them up using the WebApp/ SSH?

And one very minor nit-picky detail: the port is set to 22 but the command shows 22786

Looks very promising!

one more thing again:  wouldn't the "enable network interface" checkbox make sense as very first item since everything else depends on it? maybe grey out all the features not working if the net is disabled.
Also, does not enabling the network interface still leave the possibillity to connect via USB? If so that should be mentioned somewhere, preferably in the manual

Can't wait till I get the chance to do high speed of my black powder cannon!

I think you need Way more Light there, because those two Videos are super dark. Maybe also some Backlight would help to see the Edges of things better and makes the individual things in your frame Stand out better.
Or try to get longer exposure-times per frame, if possible also try to open up your apperture on your lens. But more Light is always good for highspeed.

Yep you need way more light! However much light you think is enough, you still need more. I also had to learn this the hard way. Moreover you appear to be using an AC source for your light, hence the "flickering". The Naked eye usually won't notice 50/60 or 100/120 Hz if the brightness does not vary too much, but for a highspeed cam it's quite noticeable.

I've had good results with sunlight, battery-powered leds and special "high-speed" circuits.

I've not yet tested filming at night (something like the stars), but you can indeed st the frame rate very low. I believe it was about 10s max exposure per frame. (You can search it on the forums here, telsa500 posted it somewhere )
However I don't think using a high speed camera is a good idea for low-light situations. It might work and you might get some useable results, but your effectively wasting money and computing power on the exact opposite kind of features you're using.

But using the camera as dual-purpose might work. I'll try to do some test shots in the coming weeks or so.

For SSH I think you need to add a field for the port because leaving the SSH server on port 22 is not a good idea (the vast majority of automated attacks by bots are on the default port, if you can change it you avoid 95 % of them).

This is then just security by obscurity and therefore not really secure. It might also break (badly designed) stuff which relies on the defaults. I do however like the general idea to be able to change the port using the UI.

I've made the screen lockable, not that it's worth very much since anyone can pop out the system MicroSD card and fiddle with the saved settings on it. I might just remove the button entirely, since perhaps it confers a false sense of security.

Indeed, get rid of the locking. It's less stuff to implement and more screenspace!

In version 2, which I like quite a bit more, I unified the HTTP API and web app controls. The web app uses the HTTP API to control the camera, so you can't really have one without the other. I figure if you're just using the HTTP API, it's not a big deal if the web app is being served in the background. You can just ignore it. Unifying the controls also freed up enough space to display the IPv4 and IPv6 addresses' QR codes on screen, which I think is less confusing. We don't use the underline anywhere else in the back-of-camera UI.

I also prefer version 2. However displaying 2 QR Codes next to each other is confusing and might be error-prone. Maybe only ever display one type of IP and add a button to switch? Like "display IPv6" ?

note: The web address section only shows up after you've enabled the network interface. The "Next Address" button only shows up if there's more than one active network interface - ie, you've plugged in MicroUSB and Ethernet, and maybe WiFi if we can get it working reliably. It'll cycle through the things which are plugged in.

Then perhaps call the button next interface or next adapter. I had to read your description to figure it out, but it should be obvious from just looking at the picture.

So, as always, please tell me you think. The best time to change designs is while they're still on the drawing board.

I like it in general!

I like it, but just a tiny nit-pick:

You'll need two labels for the Y-Axis as you are plotting two different things. 100% Voltage would not really make sense while 100% charged does.

Great footage, but why are you linking to a point somewehere in the middle of the video? The start is not bad or boring!

glad you made it!
@devs can we get updating via Ethernet in the future? Should make things easier.

the updatescript is not that complicated, you could maybe put the required files on a working sd card and then connect to the camera via ssh. From there on you could manually update things from the sd card without the cam software.

not that complicated is relative, haha. whats a ssh? im not a computer guy

SSH is a way to connect your camera to a computer and then execute commands via a terminal in text-form. It's really powerfull but has a steep learning courve.
If you can tell me the EXACT mounting point of your SD-card (something like "/dev/mmcblk0p2"; can be seen in the save dialog) I could modify the updatescript to run from there for you. You'd probably still need to start it manually as the camapp software is likely not going to see it on there but at least you won't have to do all the commands by hand.

oops, you're right. I thought they've updated it. however it would still give you a known clean state to start from.

If you want I can send you an image of my updated SD card. You would need to restore your callibration data (mine is part of the SD image). It's ~700mb but I think Google drive will share stuff that big.

Or just use the image provides on the official website:

I just noticed that in the current UI there's no way to see your battery level while you are saving videos. If you're using raw saving might take a while and It's very risky to unplug the camera then if you don't know how much charge is left.
TL;DR: make the battery icon visible on all screens or at least on those where you might be stuck for a while

do you guys just put the extracted folder on the usb stick? camupdate folder?

Yep. Just the camupdate folder extracted from the download zip to the root of an USB stick. You might also try an USB harddisk. If i remember correctly I also had trouble using some older thumbdrives and only some of them work.

Chronos User Discussion / Re: I am a professional colorist & would like to try improving your raw footage

« on: August 17, 2018, 05:10:23 AM »

the underexposing was actually on purpose, I wanted the iris to be as closed as possible to get an somewhat sharp image.
Focusing at the moment is really hard, especially outside in the sunlight. The screen is somewhat reflective and even with the focusing tools the camera provides I'm having trouble to dial it in reasonably well. I'm by no means a professional and still learning to use the camera. I cant wait for HDMI out which should make focusing a lot easier.

Also I'm pretty sure the lens was clean but I'm going to check again.

@Patrickrebstock & @NiNeff:
Please also post what settings you are using for those clips, especialy things like Gain (ISO) and Apperture /Focal length /What lens was used.
Would be realy helpfull.

All my footage is shot using the stock zoom lens: https://www.krontech.ca/store.html#!/Computar-12-5-75mm-f-1-2-zoom-lens/p/77244261/category=21981409
as far as I know there's no ISO setting, but an analog gain feature, which was set at the minimum.
Aperture for the coins was about f10
