Chronos User Discussion / Can't find digital gain setting when trying to control from camera webpage

« on: November 23, 2020, 10:59:14 AM »

Anyone know how to control the digital gain from the camera's webpage?  There is a way to control analog gain, but I haven't been able to find a way to control digital gain.

Chronos User Discussion / Why the vertical color bands

« on: November 17, 2020, 01:14:27 PM »

Hi:

I'm starting to use my color Chronos 2.1 and I'm having trouble with  color vertical bands. The bands are much worse when I lower the exposure time.  Because I'm using the camera for scientific purposes, I need to use a low exposure time around 50 microseconds.  But I still get the bands at higher exposure times although not as strongly. Is there something I can do to get rid of these?

Chronos User Discussion / Re: Playing back high-speed video

Hi.

Thanks for the input.

So, here's and example of what I'm going to place as text on my video for inclusion in a scientific paper:

10,488 FPS
583X Slow Motion

I've set the playback speed in AVS Editor (before producing it as a final video for distribution) at 0.3.  So since the original speed is 60 fps from the Chronos, the new speed would be 18 fps.

So, the 583X is calculated as follows:

10.488/18 = 582.67 or 583

Don't know about AVS editor being a ripoff, but for now it is meeting my needs.  It was cheap and I just couldn't justify paying monthly subscription fees for Adobe products, since I'm only producing videos for scientific purposes.

Please let me know if you think my calculations are in error.

Also, is that the correct way to phrase the degree of slow motion; i.e. 583X Slow Motion.

Thanks!

Chronos User Discussion / Playing back high-speed video

« on: October 14, 2020, 12:32:56 PM »

Hi All:

I just got the Chronos 2.1 last week and it is pretty cool.  But if I film something say at around 5000 fps in .mp4 format, how do I play it back?  If I use something like AVS video editor, I can only slow the speed down to .05.  I'm not sure what the speed is then.  0.05 of what?  It does seem like the higher the filming fps, the slower, in a relative sense, it plays back at a specific speed setting in the desktop software.  Ultimately my question is, how can I tell people who view my video what speed they are actually seeing, because it doesn't seem to be the speed that the video was filmed in.

Thanks.

Chronos User Discussion / Filming in black and white with Chronos 1.4 color version

« on: July 28, 2020, 02:42:20 PM »

Is it possible to have the Chronos 1.4 color version film in black and white by adjusting a setting on the camera itself?  Yes, I understand that the color version doesn't have quite the sensitivity or resolution as the monochrome version, just wondering if it is possible.

Thank you.  I just discovered that myself and was about to post.

Would you mind sharing how you create videos when you do want to do post processing?  Guidance on which format to save the video on the Chronos, which post processing software you use, etc. would be greatly appreciated.  I just need some guidance to get me started so that I can better understand the entire process on what needs to be done.

Thanks.

Chronos User Discussion / Re: Desktop software to playback chronos videos

« on: July 26, 2020, 07:43:18 AM »

Well, I'm still pretty confused.

I looked at the files that VLC can open.  The Chronos allows one to save in the following formats:

H.264
Raw 16bit
Raw 12bit
CinemaDNG
TIFF
TIFF Raw

When opening a file in VLC, I don't see any of these formats as options for Media Files or Video Files.

An article I read stated that .MP4 as a video container and H.264 as a codec are a good choice.

As I understand it, the Chronos only sets the codec not the video container.  Or am I not understanding something.

Thank you, but it looks like VLC does not work with .dng files.

Like I said I have zero experience with video.  Is VLC an acronym for VLC Media Player?

Chronos User Discussion / Desktop software to playback chronos videos

« on: July 25, 2020, 05:13:17 PM »

I'm a complete newbie with video.  I just shot my first video with my Chronos 1.4.

I'm looking for easy to use desktop software which will playback the videos that I shoot.  I'm not sure how this works since there are many individual files in each of the folders.  So software which maybe allows me to select a folder and then the software will "play" all of the files at a selected speed?

Chronos User Discussion / Re: Static IP Address

« on: July 25, 2020, 10:26:40 AM »

I was able to solve the immediate problem of not being able to save recordings.  I found the misplaced SD card and inserted it into the 1.4 camera.  I then formatted it and the camera was able to save to the card.  I guess any other storage device that has already been formatted (even if that format is FAT32 or the other supported formats) will not work.  Hopefully someone who knows more will chime in and provide more information on this topic.

With regards to running the web based GUI without an internet connection, I was not able to do this.  I did try using a network switch which did help if and only if the switch also had an active internet connection.  I think I was able to assign a static IP address, but that too did not work unless there was an active internet connection.  The only time I could bring up the web page and have the web page recognize the camera was when the switch also had an active internet connection.  Again, hopefully someone has more information on this as I was hoping to control the camera using the web page but without an active internet connection.

I tried using a switch.  As expected, it works if there is an internet connection. Once the Chronos has an assigned IP address, the internet connection can be removed and the webpage on the computer still works.

However, if the router or camera is turned off or if the network cable from camera to router is removed, then the camera IP address is lost and the webpage does not recognize the camera.

Would assigning a static IP address solve this issue?

Thanks, I'll give that a try.

While I am pleasantly surprised at how quickly I was able to start recording video, I am equally dismayed by my inability to save recordings.  I have tried everything I can think of, but nothing works.  Unfortunately, I misplaced the SD card that comes with the camera.  However, I have tried to connect a hard drive and also tried a thumb drive.  The camera recognizes that the drives are attached, but always throws up an error message when I try to save.  When using the camera interface to save, the message is almost always "Save Folder does not exist".  When I've been able to use the web page, either nothing happens after clicking "Save", when a hard drive is attached, or the message is "Recording failed. Read-only file system", when a thumb drive is attached.

I also tried inserting the SD card from my Nikon camera, but the Chronos does not recognize that it is inserted.

Chronos User Discussion / Static IP Address

« on: July 25, 2020, 08:02:49 AM »

I just received the 1.4 and am playing around with various aspects.  I would like to be able to use the web interface, however, out in the field I will not have an internet connection.

I thought that simply plugging the camera into the network connector of my computer would bring up the web page (after entering an IP address).  However, unlike a router, the IP address provided for the mini USB connection does not work when using a network cable.  Would assigning a static IP address solve this problem?  If so, how does one do that?

Also, has anyone run into the problem of attaching the camera to a computer running Windows 10 via a mini-USB causes Windows 10 to crash.  This has happened five times.  After Windows 10 restarts, the camera can be seen on the web page and operated from there.  However, if the connection is lost or a thumb drive plugged into the camera, Windows immediately crashes again.

With a network cable plugged into a router CONNECTED TO THE INTERNET, there are no crashes and the webpage readily comes up and is connected to the camera.  But I won't have an internet connection in the field.

Thanks for any help.

Chronos User Discussion / Macro Video

« on: July 14, 2020, 08:30:27 PM »

I would like to do some macro work with  the monochrome version of the 1.4 (which I should receive any day now).

Will the following lens work?

computar C-Mount 13-130mm Varifocal Lens

Listings say that it is compatible with 1/2" cameras and uses a C-mount.  I assume the 1/2" is the sensor size, but I'm not sure.

Thanks.
