At my cameras this thin line happend if I change the resolution and forgot a black calibration. Or I using the exposure slider - then I have to make a black calibration too.
Waaaaaaait. So using the exposure slider requires a black calibration afterwards?  :o Was this documented somewhere and I just completely missed it or forgot it?
I had this problem as well in the early days, so there's probably a threat about it here somewhere, but it's not exactly in the official documentation ;)

I bought a couple of these Stratus LED units with the reflector. I havent put them through their paces yet but they are a reasonably cost effective solution if you dont mind making your own mounts to hold them.

I have five or six of them and they work great! Do however be careful to not fully discharge your batteries with them, as they don't have any control circuits to prevent damage to your cells and will just run as long as physically possible. Or add a small battery management chip depending on the type of battery you intend to use.

After quite a bit of (unrelated) recalibrating of my 3D printer I finally got around to printing this. It works great! Thanks for the idea and the files!

This is a great idea, I will test this!

The m2 screws are to secure the SATA cable in the SSD holder to prevent it from moving/shifting when connected to the SSD.
Ah, thanks! I personally don't need those as the disc and cable are relatively tight in there already, but good to know.

so i would expect that more heat means, battery drains faster, and that High gain would draw more power.
As far as I'm aware recording does not consume more power than idling.
The power consumption is pretty constant apart from the fan, which obviously depends on the external temperature.

My USB-Soundcard finally broke completely yesterday after Years of hard use and Abuse. Litteraly into pieces... So today i went and bought a New USB-Audio-Interface. And the first thing to do with it is obviously hooking it up to the Trusty Hameg Osciloscope and blast Globetrotter on it to film it with the Chronos. Looks way better than the old one. Settings used: FullHD @1kfps; somewhere around 180 Shutter; 0dB Gain; Schneider-Kreuznach 50mm 0.95 @f/1.2; No grading/ Editing/ Sharpening on this one, also no denoise, just run it to AE very quickly to compress it for posting here and turn up the Saturation a bit on the Green. This one is rather long, but i kept it as is from the Camera .h264 .mp4 File anyways.
 Also, i just noticed, i maybe forgot to do Black-Calibration on the Bottle one, hence the Weird Lines all over the Shadow areas in the Image. Have to keep an eye on this, but still new to the cameras Workflow, so Black-Cal is a thing to remember bevore shooting important stuff.

That walking Stick-figure is awesome! Also congrats on finally getting your Chronos ;)

There is no in-camera option for this.
I cant speak for Krontech but personally I think there won't be such a feature anytime soon. The Monochrome Version of the cam exists already and there's enough software solutions out there to convert color Video/images to monochrome if really needed.

There's no size difference between the color and monochrome versions as far as I know.
The Datasheet says the dimensions are 8.45 x 6.76mm.

I ran into a similar problem today using an SD card. I think the issue was that I inadvertently had a "\" in the file name - what I assume is an unacceptable character. My story is the same, the camera acted like it saved normally, didn't throw a warning, and I didn't realize my mistake until I put the card into my computer and realized the file wasn't there. If there were a confirmation that the file saved, or a way to show files in the current folder, it would be very useful in my opinion. Thanks!
The file might still be there and recoverable using any system other than windows to look for it. If you don't want to install Linux or don't have a MAC use a live System booted from USB.

There are several options. You could use network storage / samba shares. You could use SSH access and then use the common linux tools or a python script. There has been one posted here on the forums, but it's quite outdated and from before we had a proper API. It might still work though.

I just noticed that if the focus aid is turned on it will be visible in the 60fps live recording. Not a problem for me but good to know before you go recording a lot.
oh this is indeed important to know!

I finally found the time to also print this SSD holder. I forgot to add supports for the print, but my printer handled it very well even without them.
I did some very quick tests an the SSD is about twice as fast as the SD card when saving DNG files, MP4 is about the same. Currently I have it formatted to FAT32, maybe I'll "upgrade" the filesystem to EXT3 or even EXT4 and see how it does then.
However reading EXT formatted Devices from Windows sucks :D


EDIT: I just saw the mounting-holes for the m2x10 screws, what are they for? As far as I can tell the holder works perfectly fine without those screws in there...

so far I have run into three issues:
 - the "OK" button on the safely remove dialog can't be clicked (neither via the touchscreen, nor via click on the cogwheel)
 - I hear wierd noises (almost sounding like a fan) on the live video audio, even without  microphone being plugged in
 - I'm sofar unable to record audio is there a special microphone needed? I tried a regular PC Headset without any amplification.

Hm, I cant find a problem in this dialog - in both windows (storage and play) it works well.
And I am also not able to record audio with the build in mic - there is only a loud hum in the clip.
It works for the SD Cards, but not for eSATA on my camera. I did not test USB.
