Can't imagine thats the issue. All other modes work fine. Also, when moving the crop to one of the corners of the sensor, the stripes are gone. I'll try to reinstall however...

Hope that it is not because of the very low serial: it is 000017...

Ok, then I really have a faulty sensor or whatever. Shit...

today I wanted to try a resolution I never tried before and I could not make it work. I tried 832x456 @ 5682 fps and got some really ugly fast moving stripes at the left side of the display, which appear in the footage too. After fiddling a while it turned out that all of the resolutions with 832 width have the same problem.

I attached three of the recorded frames, the stripes are visible in each frame. The problem appears only at this resolution. Restart, black calibration and changing gain won't change anything...

Do you encounter this on your 2.1 too? Help is really appreciated. Thanks! Martin...

General high-speed discussion / Upscaling footage
« on: July 12, 2021, 03:27:30 PM »

now that I got the sweet spots for my camera (thanks to mklinger) I tried higher frame rates to see whether the footage afterwards can be upscaled without becoming ugly.

So I tried some different approaches, but in the end I came up with two workflows that might work. Maybe this is of use for somebody, so:

1. Using Adobe camera RAWs new feature "Super Resolution", which will convert an existing DNG into a new DNG with twice the resolution while keeping the RAW data intact. Actually it bakes the upscaling recipe into the DNG. So one doesn't loose the overhead from the RAW. Unfortunately only Adobe Software can deal with theses enhanced DNGs. When scaling up a 1152x648 frame to 2304x1296, the "enhanced" DNG can be read with DaVinci, but it stays at 1152x648. So going the Adobe way the workflow is a) grade and enhance (new super resolution) the DNGs e.g. from within Lightroom, then b) export these enhanced DNGs from Lightroom as 1920x1080 TIFF sequence.

2. Grade and export the DNGs from within Lightroom without "super resolution" to TIFF, then let e.g. Topaz Gigapixel AI do its job upscaling to 1920x1080.

I attached a PSD with three layers: one from Gigapixel, one from Lightroom Super Resolution, and one from the original  DNG to TIFF without scaling. Although Gigapixel is a somewhat over the top with sharpening, I will stick to it.

There is something to mention, too: The "Enhance Photo" function does a very good job on Moiré. Look at 200% at the roof in the background, there were no vertical roof joints, it is Moiré! GigaPixel simply enlarges it, while "Enhance photo" addresses it quite well. So maybe even when using GigaPixel or equivalents for upscaling, you might want to use Adobe Camera Raws "enhance photo" additionally before exporting.

Have fun!

Great post! Haven't seen that until now. Very good, really!

Maybe this randomness is the same randomness that appears with other features of the camera? As posted here in the forum I recently had some issues with the cameras IO settings. Seems this happens to others too now and then.

Since the camera remembers its settings when being turned off and booted up again, there has to be a file or a place where the settings are stored. If the values are messed up somehow, maybe this might be a reason?

However it would be nice to know where settings are stored...

Just two put my 2 cents to this: I also had trouble booting the camera when having HDMI connected. But actually I don't use that very often, so I can't tell when and exactly und which circumstances this happened.

Did some testing with food. The camera was rigged to a rotating mount and completely detached, having a WLAN-hotspot connected to it and triggering wirelessly via IO2. Sigma 24mm 1.8, 1920x1080, 0db.

Same problem here, but not solved yet. Anyone have a fix for that?

I have this adapter, btw.

Software Dev / Feature request: Toggle Input for IO2
« on: July 03, 2021, 12:56:59 AM »
Hello, I wonder if it was possible to get a toggle function for IO2. At the moment this is available only at IO1, BNC, this makes a setup unnecessary clumsy.


OK thanks. I never touched post trigger delays. I will surely try the reset configuration option, if the issues appears again. Thanks.

Jesus, where did the Chronos 1.4 land? :-)

Aaaah! Ooooh! Uuuug! You are a magician!

Then it would be e.g. possible to alter the defaults for the Web UI, for example. Cause every time I start the web control, I need to retype the smb share information, the pass and so on.

Yes, thanks. I will try with the reference frames, but sometimes this is not possible. I would like to use the Chronos like a point and shoot, and even black calibration take a lot time sometimes. Even more saving.

Would be great to have a FPN software for cases when not having reference frames. However, if one has references, your proposal is great. Thanks!

Yes, that's for sure something I will try.

I know its always nice to be able to avoid lifting the exposure in post. The luminosity mode in the AE does some decent trick, yes, but especially when working with reference frames a dedicated algorithm could do way better, I a am sure. In the PNG there are still a lot of vertical bands visible. I tried your AEP, but I have only one frame. The problem with FPN is, that i tends to be much more annoying in movies than grainy noise, no?
